Cerbera

Cerbera is a Linux-native guardian that protects credentials by synchronously blocking unauthorized reads of sensitive data like browser profiles, SSH keys, and password databases at the kernel level before data can be exfiltrated. Its core product, Cerbera, uses Linux's fanotify to intercept and deny read access to specified paths based on a TOML configuration, preventing attacks that occur within milliseconds. The company serves developers and users who need to secure their sensitive information on Linux systems.
