Zero Trust Spending Hits $17.6B in 2026 as IAM Takes 39% of Budget

IAM becomes the dominant zero trust line item

Identity and access management now accounts for 39.2% of zero trust architecture spending in 2026, according to new Coherent Market Insights data covering the $17.6 billion market. That single functional category—user and application authentication—is larger than network segmentation, endpoint security, and data protection combined.

For enterprise buyers, this settles a two-year debate about where to anchor zero trust investments. The market has chosen: identity-centric controls win the budget war. Buyers standardizing on Microsoft Entra, Okta, CyberArk, or Ping Identity can now justify those commitments with external spending data. Buyers still assembling point products face growing pressure to consolidate around a single identity platform or explain why their approach differs from 39.2% of the market.

The forecast projects zero trust spending will reach $24.9 billion by 2033, an 8.2% compound annual growth rate. That trajectory gives CISOs a defendable external benchmark for sustained annual budget increases tied to IAM, multi-factor authentication, and continuous verification.

NIS2 penalties convert zero trust from project to mandate

The EU NIS2 Directive now applies to more than 160,000 organizations across 18 critical sectors, with non-compliance penalties reaching €10 million or 2% of global annual turnover. The Coherent report explicitly links NIS2's requirements—continuous authentication, least-privilege access, supply chain security—to accelerated zero trust adoption across European enterprises.

For buyers, this changes the cost-benefit calculation. Zero trust capabilities are no longer discretionary security improvements; they are regulatory risk mitigation expenses. EU-headquartered or EU-exposed enterprises can use the penalty structure to argue for accelerated timelines on strong MFA, micro-segmentation for critical services, and supplier access controls.

The regulatory pressure also reshapes vendor negotiations. Buyers in NIS2-covered sectors can demand reference architectures, compliance templates, and audit support as table stakes. Vendors unable to demonstrate how their tools map to NIS2 requirements for continuous authentication and least privilege lose access to a market covering 160,000+ organizations.

NIST guidance reduces implementation uncertainty

NIST released zero trust implementation guidance in June 2025 with 19 practical models for hybrid and multi-cloud environments. The Coherent report notes this framework is driving increased spending on zero trust integration, authentication, and security orchestration by reducing implementation uncertainty for enterprises and government agencies.

For buyers writing RFPs, the 19-model framework creates a filtering mechanism. Vendors must now show which NIST models they support and provide reference architectures for hybrid and multi-cloud zero trust deployments. Tools lacking those reference architectures become easier to exclude during vendor selection.

The guidance also validates platform consolidation. Enterprises assembling zero trust from multiple point products face higher integration costs and longer timelines than buyers standardizing on platforms with pre-built NIST model support. The 19-model framework makes "works out of the box" a measurable vendor requirement rather than a marketing claim.

North America captures 39% of spending, shaping vendor competition

North America holds 39.2% of the zero trust market in 2026, concentrating vendor attention and go-to-market investment in U.S. buyers. This geographic split structurally advantages U.S.-centric vendors—Okta, Zscaler, Palo Alto Networks, CrowdStrike—over smaller regional players in near-term market share capture.

For buyers, the North American concentration means more aggressive sales cycles, more pricing pressure, and more competitive discounting than counterparts in other regions will see. It also means reference customers, implementation partners, and technical support resources will be densest in North America.

The IAM and authentication focus also clarifies the primary vendor battleground. Microsoft Entra, Okta, CyberArk, and Ping Identity compete directly for the 39.2% share tied to user and application authentication. Network-focused vendors—Zscaler, Palo Alto Networks, Cisco, Netskope, Cloudflare—compete in the smaller but still material network segmentation and ZTNA segments.

What to watch

The 39.2% IAM share creates pricing power for identity platform vendors in renewals and expansions. Buyers should negotiate multi-year commits with volume caps now, before vendors internalize the market data.

NIS2 enforcement begins in earnest in 2026. Enterprises in covered sectors should map zero trust roadmaps to specific NIS2 requirements and document how IAM, MFA, and segmentation investments satisfy regulatory obligations. That documentation converts security spending into compliance budget, which is easier to defend.

The NIST 19-model framework will become the de facto RFP requirement for U.S. federal and large enterprise buyers. Vendors without NIST-aligned reference architectures by mid-2026 will lose access to those procurement cycles. Buyers should ask for NIST model mapping in discovery calls, not during final vendor selection.
