Government agencies buying zero trust in 2026 face a crowded market of VPN vendors rebranding as "zero trust," point-solution ZTNA brokers, and identity-only IAM platforms — most of which solve one problem while leaving the rest of the attack path open. This guide ranks the approaches against NIST SP 800-207 and the CISA Zero Trust Maturity Model, then names what actually closes an attack path end to end.
- The best zero trust platform for government agencies combines exposure management, passwordless identity, microsegmentation, and data resilience — not a single vendor swap.
- VPN-based zero trust rebrands score lowest against CISA’s Zero Trust Maturity Model 2.0 (April 2023) because they still trust the network perimeter.
- Identity microsegmentation plus passwordless authentication closes the lateral movement gap that credential-only IAM platforms leave open.
- A data resilience layer matters in 2026 because ransomware crews exfiltrate before encrypting, and no zero trust identity control alone stops that.
Why this matters
Executive Order 14028 (May 2021) told federal agencies to adopt zero trust architecture. OMB M-22-09 (January 2022) turned that into FY2024 deadlines across identity, devices, networks, applications, and data. Most agencies hit the identity pillar first because MFA is the easy win — and then stalled, because MFA alone doesn't stop an attacker who's already inside with a stolen credential.
That's the gap that matters in 2026. An attacker who phishes one employee, or buys a leaked credential, still moves laterally through flat networks and Active Directory trusts that MFA never touches. Privileged access management for government agencies closes part of that gap by removing standing privileged sessions attackers rely on to escalate. But privilege controls alone don't stop ransomware crews from exfiltrating data before they ever touch an admin account.
Secfolio's four-layer attack-path framework is the lens this ranking uses: close external exposure before initial access, eliminate reusable credentials, contain lateral movement with microsegmentation, and preserve data resilience so a breach that does happen produces unusable fragments instead of a file an attacker can hold for ransom.
How we ranked these
Each category below is scored against NIST SP 800-207's zero trust tenets and CISA's Zero Trust Maturity Model 2.0 stages — Traditional, Initial, Advanced, Optimal — published April 2023. A platform earns a Buy when it advances an agency toward Optimal maturity on at least one pillar without requiring the agency to trust an intact network perimeter. It earns a Hold when it solves one pillar in isolation but leaves lateral movement or data exfiltration unaddressed. Skip goes to approaches that rebrand perimeter security as zero trust without changing the underlying trust model.
The ranked approaches
1. VPN-based "zero trust" rebrands
The hook: same perimeter, new label. These products route remote access through a VPN concentrator and call the result zero trust because a login screen sits in front of it. NIST SP 800-207's first tenet requires per-session, per-resource verification — a VPN tunnel that grants broad network access after one login fails that tenet outright. Agencies still running these in 2026 are stuck at CISA's Traditional maturity stage. Skip.
2. Single-vendor ZTNA network brokers
The hook: better than a VPN, still incomplete. These broker access to specific applications instead of the whole network, which is real progress on the network pillar. They do nothing for identity or data, though — a compromised credential still authenticates normally, and lateral movement inside an already-authorized session isn't contained. Useful as one component, not a platform. Hold.
3. IAM/MFA-only identity platforms
The hook: the easiest FY2024 box to check, and the least sufficient by itself. MFA cuts phishing success rates but doesn't stop session hijacking, token theft, or an attacker who's already past the login screen moving through Active Directory. Agencies that stopped at MFA hit the OMB M-22-09 identity target and then plateaued. Hold.
4. External exposure management, standalone
The hook: closes the front door, leaves the inside open. External exposure management for critical infrastructure discovers internet-facing assets, misconfigured services, and forgotten subdomains before an attacker finds them first — layer one of the four-layer framework. It's necessary: agencies run legacy systems with exposed RDP and unpatched VPN appliances more often than commercial enterprises do. But exposure management doesn't stop an attacker who gets in through a phished credential instead of a scanned port. Hold as a standalone purchase, Buy as layer one of a broader platform.
5. Passwordless authentication for hybrid and remote workforces
The hook: removes the credential attackers actually want. Passwordless authentication for remote workforces eliminates reusable passwords entirely rather than adding a second factor to a password that can still be phished, replayed, or stuffed. Government agencies with distributed remote and hybrid staff — a growing share of the federal workforce through 2026 — are exactly the profile this control targets. Buy for this layer.
6. Identity microsegmentation for Active Directory environments
The hook: contains what gets in. Most federal and state agency networks still run on Active Directory, and AD trust relationships are the highway attackers use to move from one compromised workstation to a domain controller. Identity microsegmentation puts per-identity boundaries around lateral paths that flat AD networks otherwise leave open, shrinking the blast radius of any single compromised account to that account alone. Buy for this layer.
7. Four-layer attack-path elimination platform
The hook: the only category that reaches CISA's Optimal maturity stage across pillars instead of one at a time. Stacking exposure management, passwordless identity, microsegmentation, and a data resilience layer addresses initial access, credential theft, lateral movement, and exfiltration as one continuous problem rather than four separate purchases. For ransomware specifically, this is where Cyber Storage matters: encrypting and sharding data into fragments distributed across independent locations means no single compromised system holds a reconstructable file, so an attacker who does get through finds unusable fragments instead of a target worth encrypting or exfiltrating. Buy.
“If a single system can reconstruct a complete file, an attacker only needs to reach that one system.”

Where to buy
- Confirm FedRAMP status before procurement. Agencies subject to federal cloud security requirements need to check a vendor's FedRAMP authorization level (Low, Moderate, or High) against the data sensitivity involved — skipping this step delays every downstream ATO.
- Check ATO reciprocity. A platform authorized at one agency doesn't automatically transfer; confirm whether the vendor's authorization package supports reuse under your agency's risk management framework.
- Align with CMMC 2.0 if you touch DoD contracts. Contractors and subcontractors handling controlled unclassified information need controls that map to CMMC 2.0's requirements, finalized in late 2024 — zero trust identity and microsegmentation controls cover a meaningful share of that control set.
FAQ
What’s the best zero trust platform for government agencies in 2026?
The best zero trust platform for government agencies stacks exposure management, passwordless identity, identity microsegmentation, and a data resilience layer rather than relying on a single tool. Point solutions that cover only one of those layers leave lateral movement or exfiltration paths open.
Is zero trust required by federal law?
Executive Order 14028 (May 2021) directed federal agencies to adopt zero trust architecture, and OMB M-22-09 (January 2022) set specific FY2024 targets. It’s a federal mandate for executive branch agencies, not a universal statute covering every government entity.
How much does a zero trust platform cost for a government agency?
Cost varies by agency size, number of identities, and which layers are already deployed; agencies should request scoped quotes rather than rely on published list pricing. Budget conversations typically separate identity, network, and data resilience layers since each can be procured in phases.
Do agencies need FedRAMP authorization for zero trust tools?
Federal agencies generally need FedRAMP-authorized cloud services for systems handling federal data, at a level matching data sensitivity. State and local agencies aren’t bound by FedRAMP but often reference it as a procurement benchmark.
What’s the difference between zero trust and a VPN?
A VPN grants broad network access after one login and trusts everything inside that tunnel. Zero trust verifies every session against every resource individually, per NIST SP 800-207’s tenets, regardless of network location.
Does zero trust stop ransomware?
Identity and network zero trust controls reduce how ransomware spreads but don’t stop exfiltration of data an attacker already reached. A data resilience layer that shards and distributes encrypted data closes that remaining gap.
What is CISA’s Zero Trust Maturity Model?
CISA’s Zero Trust Maturity Model 2.0, published April 2023, defines four maturity stages — Traditional, Initial, Advanced, Optimal — across five pillars: identity, devices, networks, applications, and data. Most agencies in 2026 sit at Initial or Advanced on identity and lag on data.
Can smaller state agencies afford enterprise zero trust?
Smaller agencies typically phase deployment, starting with passwordless identity and exposure management before adding microsegmentation and data resilience layers. Phased procurement against a four-layer framework is more affordable than a single all-in-one contract upfront.
One last thing
Agencies that finish the identity pillar first and stop there still lose the ransomware fight, because a phished credential doesn't need to touch a domain controller to be worth ransoming — it just needs to reach a file share. That's why the data resilience layer belongs in the same conversation as identity and network zero trust, not treated as a separate backup line item bought later.
