When compared to Tripwire, AIDE, Graylog or other conventional SEM solutions, Trailbot offers a much more extensible and powerful policies engine that allows anyone to write, fork, customize and share their own smart policies written in javascript or coffeescript.
Other big point in favor of Trailbot is that we are strong believers and supporters of the technological sovereignty movement, so we open sourced all the components in Trailbot's stack so that you can self-host the whole thing in case you don't want to trust any third party.
In addition, all traffic going between Trailbot Watcher and Trailbot Client is encrypted end-to-end using asymmetric cryptography (PGP with 4096 bits keys).
Thanks a lot for your interest, we hope you find Trailbot useful :)
