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.
MailChannels Outbound Filtering
Hosting providers and enterprises managing high-volume SMTP infrastructure need MailChannels Outbound Filtering to stop compromised accounts from becoming reputation liabilities before they reach recipient mailboxes. The tool detects anomalous sending patterns in real time and can auto-revoke credentials via API webhook, which means you're not waiting for abuse reports to shut down a breached account. The tradeoff is real: this is a relay hardener for organizations with their own mail infrastructure, not a replacement for inbound gateway filtering or user-level email security, so don't expect phishing detection to catch much once mail has landed in inboxes.
