Mortar

Red teamers and penetration testers validating their own detection coverage should use Mortar to systematically test whether your EDR and XDR actually catch what you think they catch. The tool's free pricing and 1,501 GitHub stars reflect genuine adoption among practitioners who need to simulate evasion techniques without licensing friction. Skip this if you're looking for a commercial product with vendor support or want something that doubles as a monitoring platform; Mortar is a testing harness, not a detection layer.
