Cybersecurity Budget Benchmarks for 2026: Essential Planning Guide for Enterprise Security Leaders

Complete cybersecurity benchmarks 2026 analysis covering threat statistics, budget allocation strategies, regulatory compliance, and ROI metrics for CISOs at organizations with $2B+ revenue

Executive Summary

CISOs planning 2026 budgets face a brutal reality: global security spending hits $262 billion while breach costs average $4.88 million. For organizations with $2B+ revenue and 3,000+ devices, the question isn't whether to increase budgets—it's how to allocate dollars across people, processes, compliance, and tools that actually stop attacks.

Here's what your budget must address: ransomware attacks jumped 149% in early 2025. Attackers now move laterally through networks in just 48 minutes after breaking in. 59% of healthcare organizations suffered ransomware encryption last year. Defenders discovered 670 new OT vulnerabilities in six months. Your security budget can't just grow—it must transform to match attacker speed and sophistication.

What the 2026 Threat Data Reveals

Attacks Accelerate

Cybercrime damages will exceed $9.5 trillion in 2025. Healthcare alone saw 364 hacking incidents affecting 33 million people in 2025. No sector escapes.

Speed kills. CrowdStrike and ReliaQuest research shows attackers now move from entry to lateral spread in 48 minutes—down from 62 minutes in 2023. Worst case? Breakout in 51 seconds. That's a 22% speed increase year-over-year, shrinking your detection window to almost nothing.

Ransomware Dominates

Ransomware incidents spiked 149% in the first five weeks of 2025 compared to the same period in 2024. Attacks now happen every 19 seconds worldwide. Financial stakes? Average ransom payments jumped from $400,000 in 2023 to $2 million in 2024—a five-fold increase. Early 2025 data suggests payments now hover near $3 million.

Extortion tactics evolved beyond simple file locks. Double extortion—where attackers encrypt data AND threaten to publish stolen files—became standard. Some groups now deploy triple extortion: they target your customers or launch DDoS attacks to force payment. Sophos research shows 63% of 2024 ransomware incidents exploited software bugs as the entry point. Patch faster or pay later.

Manufacturing and healthcare organizations face particular vulnerability to ransomware due to the operational impact of downtime. When production lines halt or hospital services become unavailable, the pressure to pay ransoms intensifies dramatically. Healthcare organizations reported higher recovery costs in 2024, often exceeding the ransom demands themselves. This reality has forced security leaders to prioritize business continuity capabilities and incident response readiness alongside preventive controls.

OT Systems Under Attack

IT and OT networks converging created attack surfaces that criminals exploit aggressively. IBM X-Force tracked a 146% jump in attacks causing physical damage—equipment downtime, safety incidents, production halts. Nation-state attacks on OT tripled in 2024. These aren't just data breaches. They're attacks that stop assembly lines, destabilize power grids, and disrupt water treatment.

Researchers disclosed 670 new OT vulnerabilities in H1 2025 alone. Half rated Critical or High severity. Worse: 21% had public exploit code within days of disclosure. Attackers weaponize these flaws faster than most organizations can patch. Industrial security teams tracked at least one major OT attack with physical impact every week throughout 2024.

Attacks bridging IT and OT cost $4.56 million on average—more than pure IT breaches due to production losses. Add safety risks and regulatory fines, and the true cost multiplies. Security leaders can't treat OT as someone else's problem anymore.

Medical Devices Create Risk

Healthcare confronts a harsh truth about connected medical tech: 53% of networked medical devices carry at least one critical flaw, per FBI warnings. Another 14% run on dead operating systems with no update path. Claroty Team82 found 99% of hospitals host devices with known exploits. Worse: 89% of healthcare orgs have devices with ransomware-linked bugs accessible from the internet.

Why so vulnerable? Only 13% of medical devices support standard security agents—meaning anti-malware can't protect 87% of clinical tech. Another 21% use weak or default passwords. These flaws exist across MRI scanners, patient monitors, infusion pumps, and lab systems. Equipment essential for patient care that can't simply go offline for patches.

Healthcare orgs increased medical device security spending 75% last year. Yet only 17% feel confident they can detect and stop medical device attacks. That gap between spending and confidence? That's where patients get hurt.

Regulatory Drivers for 2026 Budgets

CISA Zero Trust Maturity Model

CISA positioned Zero Trust as the new baseline for federal agencies and critical infrastructure. Their maturity model spans five pillars: Identity, Devices, Networks, Applications & Workloads, and Data. Each pillar progresses through Traditional, Advanced, and Optimal stages. For manufacturers, healthcare orgs, and critical infrastructure operators, CISA guidance sets de facto standards even without legal mandates.

CISA's Cross-Sector Cyber Goals define baseline practices all organizations should adopt. In 2025, CISA released specific OT asset inventory guidance—you can't protect what you don't know exists. Microsegmentation and network isolation feature heavily in CISA recommendations, pushing budget dollars toward tools that enforce granular access.

Moving from Traditional to Advanced maturity across CISA's pillars typically means investing in IAM platforms, network segmentation, continuous monitoring, and automated orchestration. Organizations that adopt CISA controls proactively position themselves for future regulations while immediately blocking the attacks documented earlier.

NIST CSF 2.0 Adoption

NIST released CSF version 2.0 in early 2024—first major update since 2014. CSF 2.0 now applies to all organizations, not just critical infrastructure. New addition: a sixth core function called "Govern" that pushes cybersecurity into boardroom conversations about risk.

CSF 2.0 emphasizes supply chain risk, security measurement, and integration with enterprise risk management. Security leaders using it find themselves investing beyond technical controls into governance structures, third-party risk programs, and metrics that matter to CFOs. NIST published companion profiles, including a ransomware risk profile, that map the structure to specific threats and help prioritize spending.

Healthcare and manufacturing get extra attention. NIST SP 800-171 Rev. 3 defines protection for Controlled Unclassified Information—requirements spreading beyond government contractors. NIST's post-quantum crypto work and IoT device security guidance shape long-term budget plans, especially for equipment staying in service through 2030.

CMMC 2.0 Timeline

After years of delays, DoD's CMMC 2.0 program kicked off in late 2025 when the final rule took effect November 10. Phase 1 runs through late 2026: Level 1 certification for basic hygiene, voluntary Level 2 assessments. Defense contractors and suppliers need third-party certification proof of security controls.

Level 2 aligns with NIST SP 800-171—110 security requirements covering access control, incident response, system protection, and more. Budget for gap assessments, fixing what's broken, and paying C3PAOs (CMMC assessors) to certify you. Costs vary wildly based on current security maturity: hundreds of thousands to several million for mid-sized defense contractors.

CMMC ripples beyond direct defense work. Prime contractors push security demands down to subs and vendors. Manufacturers supplying the defense base—components, materials, services—should expect CMMC-style requirements influencing 2026 budgets whether or not they hold DoD contracts directly.

Sector-Specific Regulations: Healthcare, Manufacturing, and Critical Infrastructure

Healthcare organizations must prepare for the proposed 2025 HIPAA Security Rule updates, which would elevate network segmentation from an "addressable" specification to a mandatory requirement. Cyber insurance providers have already moved ahead of regulations, with many now requiring documented microsegmentation implementations as a condition of coverage. Healthcare organizations implementing comprehensive microsegmentation report cyber insurance premium reductions of 15-30% alongside higher coverage limits, creating a business case that extends beyond regulatory compliance.

Manufacturing and industrial organizations face increasing requirements under FDA guidance on securing Operational Technology used for medical product manufacturing, which emphasizes zone-based architectures following IEC 62443 standards. The FDA's June 2025 whitepaper calls for manufacturers to implement robust network segmentation, asset inventories, and access controls across production environments. While this guidance initially targets pharmaceutical and medical device manufacturers, the precedent suggests similar requirements may expand to other FDA-regulated industries.

Critical infrastructure operators should prepare for the Cyber Incident Reporting for Critical Infrastructure Act (CIRCIA) requirements taking full effect in May 2026. CIRCIA mandates reporting of substantial cyber incidents to CISA within specific timeframes, with non-compliance penalties potentially reaching millions of dollars. Budget planning should account for incident detection and reporting capabilities, legal review processes, and coordination with the Cybersecurity and Infrastructure Security Agency. Organizations in sectors designated as critical infrastructure—including energy, water, manufacturing, healthcare, and transportation—must ensure their security operations centers can detect reportable incidents and initiate required notifications within mandated windows.

How to Allocate: Benchmarks That Matter

Security Spend as % of IT Budget

Security should eat 10-15% of IT budgets for orgs facing high threat exposure. Global security spending hits $262 billion in 2026, up from $188 billion in 2023—double-digit growth rates. For manufacturing, healthcare, and industrial orgs with big OT footprints and regulatory mandates, aim for the high end of that range. Some need to exceed 15% to address threats documented here.

Split it this way:

• 40% security software and platforms
• 25% managed services and professional services
• 30% internal security staff
• 5% training and awareness

Your mix will vary based on maturity, threat level, and compliance needs. Organizations implementing Zero Trust or recovering from breaches often spike consulting and platform spending in transformation years, then shift back to operations later.

For 2026 specifically, plan for 8-12% year-over-year budget growth to match threat evolution and regulatory demands. This covers AI-driven analytics, XDR platforms, and identity-based microsegmentation. Organizations that froze or cut security budgets through 2024 may need sharper increases in 2026 to address accumulated gaps.

Where to Invest in Tools

Identity and Access Management - IAM platforms provide SSO, phishing-resistant MFA, adaptive access based on risk signals, and automated identity lifecycle. Budget for platform licenses plus integration work with apps, data sources, and security tools. Full IAM rollouts take 12-18 months and consume 15-20% of annual security budgets during deployment.

Network Segmentation - Attackers spread laterally in 48 minutes. Traditional VLAN-based segmentation can't keep up in hybrid environments with IoT, OT, and medical devices. Identity-based microsegmentation platforms work with existing network gear while providing granular policy enforcement. Healthcare systems report 76% TCO reduction versus firewall approaches, with deployment in week, not years. Organizations implementing microsegmentation see 45% lower breach costs when attacks happen.

XDR Platforms - Extended detection and response integrates multiple telemetry sources—endpoints, networks, clouds, apps—into unified threat detection. Organizations report 40-60% faster threat detection while consolidating point products. Budget for licenses, integration services, and analyst training to leverage these tools. Manufacturing and industrial orgs benefit from XDR that extends into OT and correlates IT security events with operational anomalies.

Invest in People and Process

Tools alone won't save you. Security talent remains scarce—Security Architects, OT Security Engineers, and Cloud Security Specialists command premium pay. Budget for competitive salaries, retention bonuses, and training. Can't hire enough? Managed security service providers (MSSPs) fill gaps, especially for 24/7 SOC work and specialized skills like OT security or cloud protection.

Incident response needs both people and retainers. Keep specialized forensics and recovery firms on retainer for rapid response when attacks hit. Average incident response engagement costs $150,000-$500,000 depending on scope—far less than the $4.88 million average breach cost when response fails. Regular tabletop exercises and simulated attacks validate procedures and find gaps before real incidents.

Vulnerability management deserves more investment given exploitation of VPNs, firewalls, and edge devices jumped 8-fold from 3% to 22% of breaches. You need automated scanning plus skilled analysts who prioritize patches based on actual risk, not just severity scores. Current median patch delay sits at 32 days—shrink that window. Budget for scanning platforms, patch automation, and personnel time to test and deploy updates across complex environments.

Industry Benchmarks You Can Use

Healthcare: Where Breaches Cost Most

Healthcare breach costs average over $7 million per incident—highest of any industry. 67% of healthcare orgs got hit by ransomware in 2024. 53% suffered encryption of critical systems. Recovery took 291 days on average. During that time? Patient care stays compromised.

Medical device security needs 20-25% of security budgets. This covers specialized asset discovery using passive monitoring, microsegmentation that isolates clinical tech from general IT, and continuous monitoring that spots weird device behavior. For a 500-bed hospital, expect initial investments of $1-4 million, with annual operating costs of $400,000-$1.2 million.

Regulatory compliance drives more spending. HIPAA Security Rule compliance remains table stakes. Cyber insurance demands specific controls before coverage—many carriers now require documented microsegmentation. Organizations implementing microsegmentation, MFA, and EDR across environments report 15-30% insurance premium drops—measurable ROI within first policy renewal.

Manufacturing: Protect Production and IP

Manufacturing orgs face twin threats: IP theft and production disruption. Manufacturers save $2-3 million annually from better network segmentation that prevents production downtime. One day of unplanned downtime in automotive manufacturing costs $2 million. Pharma production interruptions exceed $10 million daily. Security investments deliver measurable business value beyond just risk reduction.

OT security investments focus on three areas:

1. Asset inventories - Active scanning and passive monitoring to see all industrial control systems, PLCs, and OT devices
2. IT/OT network segmentation - Creating boundaries that stop threats from crossing between enterprise and production networks while enabling necessary business connectivity
3. Continuous monitoring - Detecting weird behavior patterns signaling reconnaissance, lateral movement, or imminent attacks

IEC 62443 compliance became the de facto standard for industrial security—pharma, chemical, and critical industries all adopt its zone-based approach. Rollout takes 18-36 months and costs $3-8 million for mid-sized facilities, depending on current maturity and production complexity. But IEC 62443 alignment improves security, simplifies audits, reduces insurance costs, and meets customer supply chain security demands.

Intellectual property protection requires investments in data loss prevention technologies, insider threat detection platforms, and privileged access management systems. Manufacturing organizations possess valuable trade secrets, product designs, and process innovations that nation-state actors and competitors actively target. Comprehensive IP protection programs typically consume 15-20% of security budgets and include both technical controls and legal frameworks for classification, handling, and monitoring of sensitive information.

Critical Infrastructure: Meeting Government Expectations

Organizations designated as critical infrastructure—including energy, water, transportation, and manufacturing of essential products—face elevated expectations from government agencies and regulators. CISA guidance and presidential directives increasingly establish baseline security requirements that critical infrastructure operators must meet. Budget planning should account for compliance with these mandates while recognizing that government authorities may provide limited funding support, expecting organizations to self-fund most security improvements.

The Cyber Incident Reporting for Critical Infrastructure Act implementation in May 2026 requires technical capabilities to detect substantial cyber incidents, assess their severity, and report to CISA within specified timeframes. Organizations should budget for security information and event management (SIEM) platforms capable of aggregating logs across IT and OT environments, threat intelligence feeds that enable correlation of observed activity with known attack campaigns, and defined incident classification procedures. Legal and compliance resources represent another budget component, as organizations must navigate the complex determination of what constitutes a reportable incident and coordinate responses with multiple stakeholders.

Critical infrastructure operators should also prepare for potential government-mandated security standards in their sectors. The Transportation Security Administration has issued cybersecurity directives for pipeline operators, the Environmental Protection Agency is developing requirements for water systems, and the Federal Energy Regulatory Commission continues refining NERC CIP standards for electric utilities. While these sector-specific regulations vary in their requirements, common themes include network segmentation, asset inventories, incident response capabilities, and vulnerability management programs. Organizations should allocate 10-15% of security budgets toward compliance program management, including tracking of regulatory obligations, evidence collection for audits, and coordination with oversight agencies.

Building the Business Case: Quantifying Risk and Return

Cost-Benefit Analysis of Security Investments

Security leaders must articulate the business value of proposed investments to secure budget approval from finance committees and boards of directors. The most compelling business cases quantify both the costs of potential security failures and the measurable benefits of proposed controls. Research demonstrates that microsegmentation delivers $3.50 in value for every dollar invested through reduced incident response costs, improved operational efficiency, strengthened compliance posture, and lower cyber insurance premiums.

Organizations can quantify potential breach costs using industry benchmarks tailored to their sector and size. The global average breach cost of $4.88 million provides a baseline, but healthcare organizations average over $10 million per incident, while OT-impacting breaches cost $4.56 million. Multiplying these figures by the organization's estimated annual probability of a material breach—commonly assessed at 20-30% for enterprises with $2 billion-plus revenue—yields expected annual loss from cyber incidents. Proposed security investments that reduce breach likelihood or limit breach impact can then be evaluated against this expected loss figure.

Operational efficiency gains provide another quantifiable benefit category. Organizations implementing identity-based microsegmentation report 60-80% reduction in policy management overhead compared to traditional VLAN-based approaches, freeing security and network engineering resources for higher-value initiatives. Incident response times decrease by 40-60% with comprehensive detection and response capabilities, limiting the scope and cost of security events. Automated vulnerability management reduces the time required to identify, prioritize, and remediate security weaknesses by 50% or more, addressing one of the primary attack vectors documented earlier in this analysis.

Cyber Insurance Considerations

Cyber insurance has evolved from a risk transfer mechanism to a forcing function for security improvement. Insurers increasingly require organizations to implement specific controls—multi-factor authentication, endpoint detection and response, network segmentation, and immutable backups—before providing coverage. Organizations that fail to meet these requirements face either policy non-renewal or dramatically higher premiums. Conversely, organizations that implement comprehensive security programs report premium reductions of 15-30% alongside higher coverage limits and lower deductibles.

When building security budgets, organizations should coordinate with insurance brokers to understand which controls will yield the greatest premium reductions. Microsegmentation implementations, for example, directly address insurers' concerns about ransomware spread and breach containment. Organizations can often justify security investments by demonstrating that three years of premium savings will offset implementation costs, with all subsequent savings representing pure return on investment. Some forward-thinking CFOs now view security budget increases as insurance premium reduction strategies, reframing the conversation from cost center to value driver.

Coverage gaps represent another consideration. Even with cyber insurance, organizations remain liable for breach notification costs, credit monitoring services for affected individuals, regulatory fines and penalties, and litigation expenses that may exceed policy limits. Many policies also exclude coverage for nation-state attacks or incidents resulting from known but unpatched vulnerabilities. These gaps mean that robust security programs remain necessary even for insured organizations, with insurance serving as a financial backstop rather than a substitute for preventive controls.

Action Plan: What to Do Now

Q1-Q2 2026: Immediate Priorities

Address the 48-minute lateral movement window first. Assess your current mean time to detect and respond—establish baselines you can measure improvements against. XDR platforms consolidating multiple telemetry sources enable faster investigation and response, making them high-impact early investments.

IAM improvements deliver immediate risk reduction. Audit privileged accounts now. Require phishing-resistant MFA for admin credentials. Grant privileged access just-in-time for specific tasks, not permanently. Nearly 30% of intrusions used legitimate accounts—attackers focus on compromising valid credentials, not deploying malware. Adaptive access controls that check risk signals before granting access defend against this pattern.

Vulnerability management demands attention. Unpatched flaws jumped to 22% of breaches. Find internet-facing systems. Prioritize patches based on actual exploit availability, not just severity scores. Shrink that median 32-day fix window. Automated patch deployment for OS and common apps reduces manual work while improving consistency. For OT systems and medical devices where patching faces constraints, network segmentation becomes the compensating control.

Medium-Term Initiatives for H2 2026

Network segmentation and microsegmentation implementations represent foundational security improvements that reduce blast radius and contain breaches. Unlike traditional VLAN-based approaches that require extensive network redesigns and create operational friction, modern identity-based microsegmentation platforms leverage existing network infrastructure while providing granular policy enforcement. Organizations implementing microsegmentation report deployment timelines of weeks rather than years, with comprehensive coverage across IT, IoT, OT, and IoMT devices.

The business case for microsegmentation strengthens when organizations quantify the benefits. Reducing vulnerable attack paths by 70-90% directly addresses the lateral movement tactics used in the majority of successful breaches. Manufacturing organizations benefit from production uptime protection, with microsegmentation preventing the spread of ransomware into operational technology environments. Healthcare organizations gain the ability to isolate medical devices and clinical networks while maintaining necessary connectivity for care delivery. Organizations implementing microsegmentation typically see 45% lower breach costs when incidents occur, validating the investment through quantifiable risk reduction.

Security operations center maturation should progress through H2 2026, building on Q1-Q2 detection capability investments. Organizations should establish or refine security incident classification and response procedures, ensuring that detection capabilities connect to appropriate escalation and containment workflows. Tabletop exercises and red team engagements help validate that procedures work under pressure and identify gaps before actual incidents occur. For organizations unable to maintain 24/7 SOC capabilities internally, managed detection and response services provide access to skilled analysts and specialized tools at a fraction of the cost of building internal teams.

Long-Term Strategic Investments Through 2027

Zero Trust architecture transformation represents a multi-year journey requiring sustained investment through 2026 and into 2027. Organizations should develop comprehensive roadmaps aligned with CISA's Zero Trust Maturity Model, defining progression from Traditional to Advanced and ultimately Optimal maturity across identity, devices, networks, applications, and data pillars. Budget planning should account for platform implementations, integration efforts, and the organizational change management required to shift from perimeter-based security to continuous verification of every access request.

Cloud security posture management becomes increasingly important as organizations migrate workloads to cloud infrastructure. Misconfigurations in cloud environments create exposure that attackers actively exploit, with cloud security gaps appearing in a significant percentage of breaches. Organizations should invest in cloud security posture management platforms that continuously assess configurations against security best practices, identify exposed storage or databases, and enforce consistent security policies across multiple cloud providers. Integration between cloud security tools and extended detection and response platforms enables unified visibility across hybrid environments.

Supply chain cyber risk management programs require sustained investment given that third-party involvement in breaches doubled from 15% to 30% year-over-year. Organizations should implement vendor risk assessment processes, contractual security requirements, and continuous monitoring of third-party security postures. Software bill of materials (SBOM) requirements emerging from government procurement standards will expand to commercial environments, requiring organizations to track software components and their vulnerabilities across their supply chains. Budget allocation should cover tools for SBOM generation and analysis, legal resources for contract negotiation, and the personnel required to manage vendor assessment programs.

From Reactive to Resilient: Your Next Move

2026 won't be kind to organizations that treat security as an afterthought. Attackers move in 48 minutes. Ransomware strikes every 19 seconds. 99% of hospitals harbor devices with known exploits. 670 new OT flaws emerged in six months.

But security leaders who allocate budgets wisely—across people, process, compliance, and tools—can shift the odds. Microsegmentation stops lateral movement. IAM systems block credential theft. XDR platforms cut detection time 40-60%. Organizations implementing these controls see measurable results: 45% lower breach costs, 15-30% insurance premium drops, and production uptime that competitors can't match.

Regulatory drivers add urgency. CISA Zero Trust maturity models, NIST CSF 2.0, CMMC certification deadlines, and sector mandates won't wait for your budget cycle. Organizations that move now position themselves ahead of both attackers and auditors.

Budget season isn't about defending last year's spend. Ask better questions: Which controls stop the 48-minute lateral movement? What cuts our detection time in half? Where does $1 invested return $3.50? Which tools let us fire our least effective vendors?

Security budgets either enable business velocity or constrain it. Choose tools that deploy in weeks, not years. Pick platforms that reduce, not multiply, your operational burden. Invest in controls that auditors recognize and insurers reward. Build resilience that lets your business take calculated risks instead of cowering from every shadow.

Ransomware attacks occur every 19 seconds globally, with average ransom payments reaching $2-3 million. 63% of ransomware incidents exploit unpatched vulnerabilities as entry points. Organizations should prioritize: rapid detection/response platforms (15-20% of security budget), microsegmentation to prevent lateral movement (15-20%), and vulnerability management programs (10-15%). Organizations with microsegmentation see 45% lower breach costs when attacks occur—$2.68M versus $4.88M average.

What are the 2026 compliance deadlines driving cybersecurity budget decisions?

Answer: Critical 2026 compliance milestones include: CMMC 2.0 Phase 1 (through late 2026) requiring Level 1-2 certification for defense contractors; CIRCIA incident reporting taking full effect May 2026 with 72-hour reporting windows; HIPAA Security Rule updates elevating network segmentation to mandatory status; IEC 62443 adoption becoming standard for manufacturing ($3-8M implementation over 18-36 months); and NIST CSF 2.0 with new "Govern" function requiring board-level security governance. Organizations not budgeting for these mandates face penalties ranging from contract loss (CMMC) to millions in CIRCIA non-compliance fines.

Why should healthcare and manufacturing organizations prioritize microsegmentation in 2026 budgets?

Answer: 53% of medical devices carry critical vulnerabilities, and 99% of hospitals have devices with known exploits. 670 new OT vulnerabilities emerged in H1 2025 alone. Microsegmentation delivers measurable ROI: 76% TCO reduction versus firewalls, 60-80% reduction in policy management overhead, 15-30% cyber insurance premium decreases, and deployment in weeks instead of years. Healthcare organizations implementing microsegmentation report mean-time-to-contain dropping from 4-6 hours to under 10 minutes. Manufacturing firms save $2-3 million annually by preventing production downtime.

How should security leaders use CISA and NIST frameworks for 2026 budget justification?

Answer: CISA's Zero Trust Maturity Model defines Traditional, Advanced, and Optimal maturity across five pillars (Identity, Devices, Networks, Applications, Data). Progressing from Traditional to Advanced typically requires 12-24 months and 15-25% of annual security budgets. NIST CSF 2.0 adds "Govern" function, pushing security into board discussions. Budget allocation by NIST function:

• Identify: 20%
• Protect: 35%
• Detect: 20%
• Respond: 15%
• Recover: 10%

Organizations demonstrating CISA/NIST alignment report 15-30% cyber insurance premium reductions and faster audit cycles. These frameworks provide board-ready justification: "We're implementing controls recommended by CISA and NIST to meet federal baseline standards that apply across critical infrastructure."
