VPN Replacement in 2026: From Encryption to Invisibility

VPNs are a 1990s solution to a 2020s problem. They were designed for an era when corporate networks had a clear perimeter and "remote access" meant dialing in from a hotel room. That era is over.

In the past three years, VPN concentrators have been the entry point for some of the most damaging cyberattacks: Pulse Secure's CVE-2021-22893 gave attackers persistent backdoors across government agencies. Fortinet's CVE-2023-27997 enabled pre-authentication remote code execution. Cisco's CVE-2023-20269 let ransomware groups walk into corporate networks.

The common thread: VPN concentrators are permanently visible on the internet, and they're the highest-value target on most corporate networks.

Why VPNs Can't Be Fixed#

The VPN model has a structural flaw: VPN endpoints must be publicly accessible. They need open ports (UDP 500, 4500, TCP 443), DNS records, and the ability to accept connections from anywhere. This means:

1. They're always scannable. Every attacker can find your VPN concentrator in seconds.
2. They're high-value targets. Compromising the VPN gives access to the entire network.
3. CVEs are devastating. A single VPN vulnerability can expose your entire organization.
4. Access is too broad. Once authenticated, users are "on the network" with access to resources far beyond what they need.

Making VPNs "better" — stronger encryption, better authentication, split tunneling — doesn't fix these problems. As long as the VPN endpoint is visible and grants broad access, the fundamental vulnerabilities remain.

The Post-VPN Model: Invisible Infrastructure#

The replacement for VPNs isn't a better tunnel to a visible server. It's making the server invisible.

With network hiding:

• No visible endpoint: There is no VPN concentrator for attackers to find. No open ports, no DNS records, no response to scans.
• Per-resource access: Users access exactly one resource per session, not an entire network segment.
• Automatic expiration: Access credentials (QURLs) self-destruct after use. No persistent credentials to steal.
• Agentless access: No VPN client to install, configure, and troubleshoot on every device.

The experience for users is simpler, not harder: authenticate through your existing SSO (Okta, Azure AD), click the QURL, and you're connected to the specific resource you need. When you're done, the connection disappears. No VPN client hanging in your system tray, no split tunneling decisions, no "you must be on VPN to access this."

The Numbers#

| Metric | Traditional VPN | Network Hiding (LayerV) | |--------|----------------|------------------------| | Visible attack surface | Always present (open ports, DNS) | Zero | | Authentication latency | 100-300ms handshake | < 50ms (p99) | | Access scope | Network segment | Single resource | | Credential theft impact | Full network access | One resource, time-limited | | Client software | Required on every device | None (browser-based) | | CVE exposure | Constant target | No visible endpoint to exploit | | Deploy time | Days (concentrator + client) | Minutes (DNS change) |

What Enterprises Are Actually Doing#

The enterprise migration away from VPNs is happening in two phases:

Phase 1 (2020-2025): VPN → ZTNA. Organizations replaced VPN concentrators with Zscaler Private Access, Cloudflare Access, or similar ZTNA solutions. This improved access control but didn't eliminate infrastructure visibility.

Phase 2 (2025+): ZTNA → Network Hiding. For infrastructure that should have zero network presence — admin panels, cloud resources, APIs, internal tools — organizations are adding network-layer hiding on top of or alongside ZTNA.

The White House national cyber strategy accelerated Phase 2 by explicitly calling for "denying adversaries initial access" — not just controlling access, but preventing discovery.

Making the Switch#

If you're still running a VPN for remote access, the migration path to invisible infrastructure is:

1. Identify high-value resources: Admin panels, databases, CI/CD, staging environments, API endpoints
2. Protect with LayerV: DNS change via proxy mode — resources become invisible in under an hour
3. Migrate users: Users authenticate via existing SSO. No client software to deploy.
4. Decommission VPN: Once all resources are hidden, the VPN concentrator can be shut down

The free sandbox at LayerV includes 500 QURLs per month for experimentation. Growth tier ($299/month) unlocks full proxy-mode cloaking for production infrastructure.

Your VPN concentrator is being scanned right now. Make it disappear.
