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.
Mimecast Collaboration Threat Protection
Organizations with distributed teams relying heavily on Microsoft 365 collaboration tools should start here for malware and phishing defense in Teams, SharePoint, and OneDrive, where most other email security platforms simply don't scan. The 14-day lookback threat scanning combined with continuous file inspection means you catch compromises that slip past initial detection, and the cloud-native deployment means no additional infrastructure to manage. Skip this if your organization needs post-breach recovery workflows or advanced insider threat detection; Mimecast Collaboration Threat Protection is built for early threat identification, not incident response.
