Skip this if your primary need is user awareness training; GreyMatter is built for teams that want automation to do the heavy lifting on incident response, not behavior change.
Security teams under siege from phishing will find Keepnet Incident Responder's automation genuinely useful; the platform removes detected threats across inboxes and archives in minutes rather than hours, which matters when your inbox is the attack surface.
