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.
Mid-market and enterprise security teams drowning in phishing false positives will find real value in Egress Defend's behavioral AI that learns individual user patterns instead of firing on every suspicious link.
