Intelligence Committee member Ron Wyden wants CISA, OMB and NIST to lead a federal effort to rout out obsolete VPNs from the U.S. government.
Analysis Summary
# Regulation/Compliance: Federal Zero-Trust Remote Access Transition (Proposed)
## Overview
This initiative seeks to mandate the removal of obsolete, internet-facing Virtual Private Networks (VPNs) across the U.S. federal government. The goal is to replace legacy perimeter-based security with Zero-Trust Architecture (ZTA) to mitigate vulnerabilities exploited by nation-state actors (specifically Russian and Chinese entities).
## Key Details
- **Issuing Authority:** CISA, OMB, and NIST (requested by Sen. Ron Wyden/Senate Intelligence Committee)
- **Effective Date:** Pending (Proposed two-year phase-out)
- **Jurisdiction:** Federal Civilian Executive Branch (FCEB), Department of Defense (DoD), Intelligence Community, and Federal Contractors
- **Status:** Proposed / Legislative Advocacy
## Requirements
### Mandatory Requirements (Proposed)
1. **Purge Legacy Gateways:** Complete removal of all public-facing, legacy remote-access VPN servers.
2. **Migration to Zero-Trust:** Implementation of remote access solutions that do not "broadcast presence" on the public internet.
3. **Identity Verification:** Continuous, context-aware authentication for every access request.
4. **Contractor Compliance:** Federal contractors must adhere to the same remote access standards as the agencies they serve.
### Recommended Practices
1. **Cloaking Entry Points:** Utilizing technologies that hide remote access gateways from public internet scanners.
2. **Least Privilege Access:** Granting employees access only to specific applications rather than broad network segments.
## Affected Organizations
- **Industries:** Federal Government, National Security, Defense Industrial Base (DIB).
- **Organization Size:** All federal agencies and associated third-party contractors.
- **Geographic Scope:** United States (Federal Infrastructure).
## Compliance Timeline
- **Current Phase:** Congressional call to action and directive to OMB/CISA (July 2026).
- **Short-term Milestone:** NIST to develop implementation standards for migration.
- **Intermediate Milestone:** OMB to issue a formal memo directing agency investment.
- **Final Deadline:** Full purge of insecure systems within **24 months** of the final order.
## Implementation Guidance
### Assessment Phase
- **Inventory Discovery:** Scan and identify all internet-facing legacy VPNs (e.g., Cisco, Fortinet, Ivanti, Check Point).
- **Vulnerability Mapping:** Identify years-old vulnerabilities and unpatched gateways currently exposed to the public web.
### Implementation Phase
- **Architectural Shift:** Transition from perimeter-based VPNs to Zero-Trust Network Access (ZTNA).
- **Procurement:** Invest in modern "invisible" remote access tools that offer granular application-level access.
### Validation Phase
- **Assumed Breach Testing:** Conduct penetration testing assuming an attacker is already inside the network.
- **Scanning Verification:** Ensure that remote access points are no longer discoverable via public internet scanning tools.
## Technical Requirements
- **Zero-Trust Architecture (ZTA):** Must align with NIST SP 800-207.
- **Authentication:** Multi-factor authentication (MFA) is mandatory; preference for hardware-based or phishing-resistant tokens.
- **Micro-segmentation:** Replacing broad network access with secure tunnels to specific resources.
## Penalties & Enforcement
- **Fines:** Loss of federal funding or contractual penalties for non-compliant government contractors.
- **Other Consequences:** Increased risk of administrative sanctions; potential for "Binding Operational Directives" (BODs) issued by CISA.
- **Enforcement:** CISA and OMB oversight through federal cybersecurity scorecards and audits.
## Related Standards
- **NIST SP 800-207:** Zero Trust Architecture framework.
- **Executive Order 14028:** Improving the Nation’s Cybersecurity (the foundational driver for Zero Trust).
- **CISA Zero Trust Maturity Model:** Provides the roadmap for agency transition.

## Practical Recommendations
1. **Stop Buying Legacy VPNs:** Immediate moratorium on the purchase of traditional, perimeter-based remote access gear.
2. **Prioritize Ivanti/Fortinet/Cisco Replacements:** Focus first on the hardware brands specifically cited in current nation-state exploit campaigns.
3. **Audit Contractors:** Send formal inquiries to all third-party vendors regarding their use of legacy VPNs to access agency data.
