CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Microsoft 365 administrators managing credential phishing at organizations under 5,000 users will find real value in EAST Anti-Phishing Tool because the CSS-based deployment model actually stops phishing pages from rendering correctly on your own login portal, blocking the attack before users even type credentials. The free model with no per-seat licensing means you get Entra-native protection without budget negotiation; deployment takes under an hour through the portal interface. Skip this if your environment runs hybrid identity systems outside pure Entra or if you need detection and response capabilities beyond the login page itself.
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. The platform's time-of-click verification and one-click remediation directly address the gap between detection and human response, cutting remediation friction that legacy tools create. Skip this if your organization needs a unified email security stack that also handles data loss prevention; Egress Defend stays focused on phishing and leaves DLP to other tools.
