Zero trust network access

It's time to stop relying on single knowledge factors like usernames and passwords, that are easily compromised and allow bad actors to roam freely.

Step beyond VPN

A single point of failure is bad news for a business; but a golden opportunity for a bad actor. And unfortunately, that's exactly what a VPN's authentication process is. If they circumnavigate it, then they can – and will – cause immeasurable damage.

With Callsign, you don't need to worry – we identify users at an individual level, meaning we can spot a bad actor even if they know a legitimate user’s password. Our Zero Trust approach gives you and your teams greater assurance around the integrity of your network.
