Download of CatoClient 4.5.2 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X was originally developed by Cato Networks. We recommend checking the downloaded files with any free antivirus. The software relates to Security Tools.
From the developer:
Cato Client allows a simple, secure, and user-friendly connection to Cato's Cloud. It provides businesses with a simple, affordable, and enterprise-grade secure network - at the fraction of the cost of legacy approaches. By rethinking network security from the ground up and bringing it onto the Cloud, securely connecting your business is simple again.
