Brands named, in the order the engine gave
- Mimecast mentioned
Quick flag on the sources: a lot of the top-ranking "best of 2026" listicles are affiliate/vendor-adjacent content, and one of them mixed up brands (it attributed "Harmony Email" pricing to Mimecast - Harmony Email & Collaboration is Check Point's product, formerly Avanan).
- Check mentioned

The answer, as recorded
Quick flag on the sources: a lot of the top-ranking "best of 2026" listicles are affiliate/vendor-adjacent content, and one of them mixed up brands (it attributed "Harmony Email" pricing to Mimecast - Harmony Email & Collaboration is Check Point's product, formerly Avanan). Treat the specific dollar figures below as ballpark list prices, not quotes. Here's what I'd actually recommend, in order: **1. Microsoft Defender for Office 365 (Plan 1)** - Start here before buying anything. If you're on Microsoft 365 Business Premium, it's already included at no extra cost, and most small businesses haven't turned on Safe Links, Safe Attachments, or anti-phishing policies properly. Configuring what you own is the highest-return move. Plan 1 standalone is roughly $2/user/month if you're on a cheaper M365 tier. **2. Check Point Harmony Email & Collaboration (formerly Avanan)** - My top pick for a *paid* add-on if you're a Microsoft 365 or Google Workspace shop. It's API-based rather than a true gateway, so there's no MX record change, no mail-flow risk, and it scans internal email too (which a gateway can't see). It also consistently tests well on business email compromise. Downside: quote-only pricing and no archiving. **3. Barracuda Email Protection** - Best "one vendor, one bill" option. Around $5/user/month MSRP, and the bundles fold in archiving, encryption, backup, and phishing training. If you want to stop evaluating products and just have it handled - especially via an MSP - this is the pragmatic answer. **4. Proofpoint Essentials** - The SMB-packaged version of genuinely enterprise-grade threat intel, roughly $3-4/user/month basic and $7-9 for the Pro tier with outbound DLP. Pick this if you're in a regulated industry or need DLP on outbound mail. It's more admin overhead than the others. **5. Abnormal Security** - Narrower pick: it's the strongest at vendor fraud and invoice/payment-redirect BEC specifically. Worth it if you move real money by email. Priced and sized more for mid-market, so it may be overkill under ~50 seats. **6. IRONSCALES** - Several listicles rank it #1 for SMB on the strength of transparent per-user pricing and a fast M365 setup. That's a fair description, and the user-reporting/remediation loop is genuinely good, but I'd put it below the above on raw detection. Reasonable shortlist candidate, not where I'd start. One structural note: traditional gateways (Mimecast, Proofpoint's gateway line) require repointing your MX records, which means they become a single point of failure for all your mail. For a small business without a dedicated IT team, the API-based options (Check Point, Abnormal, IRONSCALES) are lower-risk to deploy and trivial to remove if you don't like them. Mimecast remains strong if email *continuity* - mail flowing during an M365 outage - is the thing you care about most.
