CST VerdictBased on our analysis of NIST CSF 2.0 coverage, company size fit, deployment model, here is our conclusion:
Cloudflare Cloud Email Security
Mid-market and enterprise teams looking to cut email attack surface without ripping out existing infrastructure should start with Cloudflare Cloud Email Security; it integrates at the DNS and network layer rather than requiring agent deployment, which accelerates rollout in sprawling environments. The platform scores strongest on NIST Detect and Analyze functions, meaning it catches phishing and malware reliably but assumes your incident response process already exists downstream. Skip this if your organization needs deep post-breach forensics or user behavior analytics layered on top of threat blocking; Cloudflare stops threats at the perimeter, not inside the mailbox.
Security teams with custom Yara detection rules and IMAP-accessible mail systems should consider yaraMail when you need attachment scanning without vendor lock-in to commercial email security platforms. It's free and handles rule extraction directly from your existing IMAP feeds, which matters if you're already invested in Yara for endpoint or network detection. Not useful for organizations needing centralized policy enforcement, user reporting workflows, or threat intelligence feeds; the 28 GitHub stars and minimal documentation suggest this is a specialist tool for teams comfortable operating detection logic themselves.
