Remote work is here to stay, but many organizations still approach it with the old VPN model: one tunnel, then free access to the whole network.
That’s exactly the problem: once an infected device enters the tunnel, it can reach everything. Zero Trust flips the assumption — no device or user is trusted by default.
In practice this means multi-factor authentication, device health checks before connection, and access only to the specific service a user needs — not the entire network.
Moving to zero trust isn’t an overnight project, but it can be phased: sensitive services first, the rest later. The result is a dramatically smaller attack surface.
