Fortra Email Security & Anti-Phishing

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.

Zivver Secure Business Email

Mid-market and enterprise teams with strict data residency or compliance requirements will get the most from Zivver Secure Business Email, particularly its automated outbound content scanning that catches data exfiltration before it leaves your network without requiring manual intervention. The platform holds GDPR, NIS2, DORA, and HIPAA certifications simultaneously, which matters if you operate across regulated jurisdictions. Skip this if your priority is inbound threat detection alone; Zivver's strength is preventing what employees accidentally send out, not just blocking what arrives in the inbox.
