Abusix Email Threat Protection
SMBs and mid-market teams running legacy mail servers will get immediate value from Abusix Email Threat Protection because DNS-based blocklists stop malicious traffic before it hits your infrastructure, not after; the 99.6% catch rate on inbound threats is real throughput, not marketing math. The tool integrates directly into existing mail stacks without rip-and-replace, and its Guardian Mail component delivers instant mitigation at the gateway level. This is not a replacement for post-delivery threat detection or user awareness training; if your threat model depends on catching phishing after it lands in inboxes, you're buying the wrong tool.
Phishing Intelligence Engine (PIE)
Security teams managing Office 365 tenants without dedicated phishing forensics tooling should start with Phishing Intelligence Engine; it extracts signal from Message Trace logs that most teams leave unanalyzed, turning native telemetry into actionable detection patterns at zero cost. The 180 GitHub stars and active-defense framework design show this sees real deployment in mature shops, not abandoned proof-of-concept code. Skip this if your organization already runs a dedicated phishing sandbox or has analyst bandwidth to manually hunt; PIE solves the gap between "we have logs" and "we can act on them.
