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.
Startup and SMB security teams protecting Microsoft 365 will benefit most from Attic M365 FREE because it stops AiTM phishing attacks that bypass MFA, the attack class traditional email filters miss entirely. The tool deploys in five minutes with no payment required, making it immediately useful for resource-constrained teams, and its real-time detection of fake login pages covers both NIST PR.AA and DE.CM functions simultaneously. Skip this if your organization needs protection beyond Microsoft 365 or runs a heterogeneous SaaS stack; Attic is deliberately focused on one platform and one threat vector.
