Replace the network perimeter with per-request authorization.
Give people, devices, and agents scoped access to internal systems without a flat network.
Access used to be a location question. Being on the network meant being trusted. That assumption does not survive contractors, distributed teams, unmanaged devices, and automated agents that need to reach internal systems on their own credentials.
This is where VPNs fail quietly. A single tunnel grants more reach than anyone intended. Contractor access outlives the contract. Nobody can answer which systems a given identity can reach today without reading a firewall config.
Zero Trust Access moves the decision to each request. It gives the team a clearer way to broker access by identity, device posture, and context across internal applications, SSH targets, and private services, using Cloudflare Access, AWS Verified Access, Google BeyondCorp, or Microsoft Entra as the enforcement point. What matters next is scoped reach, immediate revocation, and an auditable record of who reached what.
Start with the widest tunnel —
Pick the VPN path or shared credential that grants the most unnecessary reach and replace it with per-application access.
Attach policy to identity and posture —
Define access by who is asking, what device they are on, and what the request is for, rather than by network location.
Make revocation immediate —
Ensure access can be withdrawn in one place and takes effect everywhere, including for automated agents holding their own credentials.
Outcomes
Scoped reach —
Each identity reaches only the systems its role requires, with lateral movement closed off by default.
Faster onboarding and offboarding —
Contractors, new team members, and agents gain and lose access through one governed path.
Auditable access record —
Every request carries identity and context, producing a reviewable trail of who reached what and when.
