The Deep Security Agent and online help are made available in ZIP packages. These packages are digitally signed. You can check the digital signature on the ZIP file in the following ways:

Check the signature on installer files (EXE, MSI, RPM or DEB files)

The installers for the Deep Security Agent and Deep Security Notifier are digitally signed using RSA. The installer is an EXE or MSI file on Windows, an RPM file on Linux operating systems (Amazon, CloudLinux, Oracle, Red Hat, and SUSE), or a DEB file on Debian and Ubuntu.

The instructions below describe how to check a digital signature manually on an installer file. If you'd like to automate this check, you can include it in your agent deployment scripts. For more on deployment scripts, see Use deployment scripts to add and protect computers.
