What is ZTNA—and Why Move Beyond VPN?
As businesses embrace cloud services and hybrid working, traditional security approaches are falling behind. One major shift is the move from VPN (Virtual Private Network) to ZTNA (Zero Trust Network Access). Here’s what that means—and why it matters.
What is ZTNA?
Zero Trust Network Access is built on a simple idea: never trust, always verify. Instead of assuming users inside your network are safe, ZTNA continuously checks identity, device, and context before granting access.
Unlike VPNs, which typically expose large parts of a network, ZTNA connects users only to the specific applications they need. This “least privilege” model greatly reduces risk if credentials are compromised.
The Limitations of VPN
VPNs have long been the standard for remote access, but they come with drawbacks:
-
Too much access: Users often gain broad network visibility.
-
Performance bottlenecks: Traffic is routed through central gateways, causing latency.
-
Scaling challenges: Expanding VPN capacity can be complex and costly.
-
Security concerns: Once authenticated, users are often trusted too much.
In today’s distributed environments, this approach is increasingly outdated.
Why Move to ZTNA?
ZTNA provides clear benefits for modern organisations:
-
Stronger security with continuous verification
-
Better performance via direct application access
-
Greater scalability through cloud-based architecture
-
Reduced attack surface as apps aren’t publicly exposed
It aligns security with how people actually work today.
Why AMS IT Support Recommends Twingate
At AMS IT Support, we guide businesses through the transition to Zero Trust—and we recommend Twingate as a leading solution.
Twingate enables secure, seamless access to internal systems without the complexity of VPNs. It integrates easily with identity providers and allows precise, granular access control.
Key benefits include:
-

Final Thoughts
ZTNA isn’t just an upgrade—it’s a necessary evolution. As cyber threats grow and workforces become more flexible, relying on VPNs alone is no longer enough.
If you want to strengthen security and simplify access, ZTNA is the way forward—and AMS IT Support can help you adopt it with confidence.
