The VPN Replacement Playbook: How Trinity Cyber Delivers Real Zero Trust

In 2025, VPNs and the firewalls they terminate on were the most exploited attack surface in the enterprise.

Conventional Zero Trust Network Access (ZTNA) was created to replace VPNs. And it is an improvement. But most ZTNA solutions don't address a core security risk: they focus on who is connecting and ignore the session payload content. That leaves a fundamental gap: a more controlled on-ramp to the same inadequate threat inspection. Which only detects the threat after it is in your environment and costly damage has begun, if at all.

If you're managing a team stretched thin by alert queues, maintaining a VPN you know is a liability, or evaluating ZTNA solutions that can't tell you what's moving through the sessions they approve — this guide was written for you.

What’s Inside:

• Why the VPN problem is bigger than you think
• Why “Just Add ZTNA” is insufficient
• How a new model for preemptive threat defense, identity-aware ZTNA with Full Content Inspection^™, stops threats before they land

Trinity Cyber didn’t wait. We pioneered the preemptive defense approach.
