Open Group Sets 2025 Zero Trust Standard, Forcing Vendor Alignment on Interoperability

Standards Activity Replaces Marketing Definitions

The Open Group's Zero Trust Architecture Working Group is building a formal reference model and consolidated standard for zero trust, with the first iteration expected early to mid 2025. For enterprise buyers, this marks the point where zero trust stops being a vendor marketing term and becomes a testable set of interoperability and certification criteria.

The working group plans to release a snapshot in spring or summer 2025, followed by a consolidated standard that could support future certification programs. This matters because procurement teams can now anchor RFP language and architecture roadmaps to a neutral model rather than individual vendor frameworks. The shift reduces integration risk and gives buyers a common basis for comparing claims across SASE, identity, endpoint, and network segmentation products.

Vendor Pressure to Align Frameworks

A formal standard creates competitive pressure on Zscaler, Palo Alto Networks, Cisco, Fortinet, Okta, Microsoft, and IBM to align their zero trust messaging and product integrations around a shared model. Currently, each vendor defines zero trust differently depending on whether their primary product is SASE, IAM, or endpoint security. A third-party standard removes that ambiguity.

Buyers gain leverage in two ways. First, vendors will need to demonstrate conformance to the standard rather than relying on proprietary definitions of "zero trust." Second, procurement teams can use the reference model to tighten requirements around policy enforcement, identity verification, device trust, and continuous assessment without becoming dependent on a single vendor's terminology.

Federal Adoption Shapes Enterprise Expectations

The U.S. General Services Administration continues to embed zero trust architecture in federal IT security procurement and guidance. This matters because federal adoption patterns often drive compliance expectations in regulated industries, especially healthcare, financial services, and defense contractors.

Vendors with strong federal credentials and compliance packaging gain an advantage, particularly those already selling identity, network segmentation, and secure access service edge products into government accounts. Enterprise buyers in regulated sectors should expect auditors and assessors to ask for zero trust alignment even if no specific regulation mandates it yet. Federal positioning creates a de facto compliance expectation.

Market Scale Drives Platform Consolidation

The zero trust architecture market reached approximately $29 billion to $34.5 billion in 2023-2024 and is projected to grow to $84 billion to $85 billion by 2030. The scale explains why incumbent security platforms and specialized zero trust vendors are aggressively bundling and expanding across IAM, SASE, and endpoint categories.

For buyers, large and rising market size means sustained vendor investment but also more aggressive pricing, packaging, and cross-sell motions. This creates negotiation leverage. Vendors need to win platform consolidation deals to capture the growth forecast, which means buyers can push for better pricing, expanded licensing, and integration commitments when evaluating multi-product suites.

What to Watch

Track the Open Group's reference model release in early to mid 2025. Procurement teams should begin aligning internal architecture requirements and RFP language to the emerging standard now, even before vendor products change. This positions buyers to demand conformance testing and interoperability guarantees rather than accepting vendor-specific frameworks.

Watch for vendors who move early to align with the standard versus those who resist. Early movers signal confidence in their architecture. Resistance often indicates proprietary lock-in risk. Use the standard as a forcing function in contract negotiations to lock in integration commitments and reduce future switching costs.
