Short answer

SMB and mid-market shops defending Microsoft Exchange on-premises will find ESET Mail Security's value in its lightweight footprint and clustering support for scaling without infrastructure sprawl. The tool covers both anti-malware and anti-phishing with homoglyph detection, addressing the two highest-frequency email attack vectors without requiring architectural redesign. Skip this if your environment is pure cloud; the on-premises focus means you'll lose efficiency managing hybrid Microsoft 365 mailboxes alongside Exchange, and the remote scanning capability doesn't fully compensate for that friction. Mid-market and enterprise security teams drowning in phishing and BEC attacks will see immediate ROI from Fortra Email Security & Anti-Phishing because its DMARC enforcement and account takeover detection actually stop the attacks that make it past your initial filters. The platform covers five of the five NIST CSF 2.0 Protect and Detect functions, with particular strength in continuous monitoring and identity controls that catch lateral movement after compromise. Skip this if your organization needs a single unified email and web gateway; Fortra is email-focused and doesn't pretend otherwise.
