The idea of a “network perimeter” feels outdated now. Users work from everywhere, devices move across networks, and applications live in the cloud.
What has stayed constant is the endpoint. It’s authenticated, monitored, patched, restricted, and often decides whether access is allowed at all.
Starting to feel like endpoint management is quietly replacing the firewall as the real perimeter.

I agree, especially when access decisions are no longer based on where you connect from, but what state the device is in.
If a device is unpatched, jailbroken, missing encryption, or failing compliance checks, it doesn’t matter whether it’s on VPN, or corporate Wi-Fi access gets blocked. That’s a perimeter decision, just enforced at the endpoint instead of the edge.
I’d say it’s less about replacing the perimeter and more about moving it closer to the user. Networks still matter, but endpoints now carry identity, posture, and risk signals. Endpoint management becomes the enforcement layer that feeds everything else conditional access, zero trust, and even incident response.
If the endpoint isn’t trusted, nothing else downstream really is.
