Microsoft Exchange 2019 Transport Filtering Agent vs Hornetsecurity 365 Total Protection: 2026 Comparison

Microsoft Exchange 2019 Transport Filtering Agent

Exchange administrators running on-premises Microsoft Exchange 2019 who need malware detection at the transport layer without licensing costs should evaluate Transport Filtering Agent; it intercepts messages before they reach user inboxes and integrates with third-party scanning engines rather than forcing you into a vendor-locked email gateway. The tool is free and deploys directly into your existing Exchange infrastructure, cutting the decision friction that kills most email security projects. Skip this if you've already standardized on cloud email or need advanced phishing/BEC detection; Transport Filtering Agent prioritizes malware blocking over social engineering defenses, and the 20 GitHub stars signal limited community adoption and active maintenance compared to mature alternatives.

Hornetsecurity 365 Total Protection

SMB and mid-market teams without dedicated backup infrastructure will find real value in Hornetsecurity 365 Total Protection because unlimited storage across 12 regional data centers removes the cost guessing game that kills most M365 backup projects. The platform covers the full NIST recovery cycle, PR.DS through RC.RP, meaning you're not just protecting against threats but actually able to restore fast when incidents happen. Skip this if your organization needs detection-heavy threat hunting; Hornetsecurity prioritizes BEC prevention and compliance over continuous monitoring for advanced intrusions.
