SquareX

SquareX is a Browser Detection and Response (BDR) solution that detects, mitigates, and threat-hunt client-side web attacks in real time. The job it does: assessing, monitoring and responding to security threats on your behalf.

It makes the most sense for companies without a full security team. They also list Cyber Security, so expect those to show up in the feature set.

SquareX is based in Palo Alto, California and founded in 2023. More on sqrx.com.

Things worth asking about: response times, what is included in monitoring, and reporting. Get the renewal terms in writing before the first invoice.

If you have worked with SquareX, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
