The question asked, verbatim: best email security gateways for remote teams

Brands named, in the order the engine gave

1. Google Workspace mentioned
   A quick framing note first, since it changes the answer: for a remote team on Microsoft 365 or Google Workspace, you probably don't want a gateway.
2. Slack mentioned
   API deploy on M365/Google, inline-mode blocking before the user ever sees the mail, and it covers Teams/Slack/OneDrive/Drive too, which is where remote teams actually leak files.
3. IRONSCALES mentioned
   IRONSCALES - The best pick if you have no security staff.
4. Abnormal AI mentioned
   Abnormal AI - Where I'd go if your real risk is wire fraud, vendor invoice fraud, or account takeover rather than commodity spam.
5. AI mentioned
   Abnormal AI - Where I'd go if your real risk is wire fraud, vendor invoice fraud, or account takeover rather than commodity spam.
6. Microsoft Defender recommended
   Microsoft Defender for Office 365 Plan 2 - Not a strong recommendation on merit, but if you're already on E5 or Business Premium you own it.
7. Office Pride recommended
   Microsoft Defender for Office 365 Plan 2 - Not a strong recommendation on merit, but if you're already on E5 or Business Premium you own it.
8. Proofpoint mentioned
   Proofpoint or Mimecast - Real gateways, and I'd only steer you here if you need heavy compliance archiving, e-discovery, or you're a few thousand seats with regulatory obligations.
9. Mimecast mentioned
   Proofpoint or Mimecast - Real gateways, and I'd only steer you here if you need heavy compliance archiving, e-discovery, or you're a few thousand seats with regulatory obligations.
10. Real DRaaS mentioned
    Proofpoint or Mimecast - Real gateways, and I'd only steer you here if you need heavy compliance archiving, e-discovery, or you're a few thousand seats with regulatory obligations.

The answer, as recorded

A quick framing note first, since it changes the answer: for a remote team on Microsoft 365 or Google Workspace, you probably don't want a *gateway*. Classic SEGs (MX-record rerouting) were built for on-prem mail. API-based platforms deploy in minutes, see internal east-west mail, and can claw back a message after delivery - which matters when your users are on home networks and personal devices. Here's who I'd actually name, in order: **1. Check Point Harmony Email & Collaboration (formerly Avanan)** - My default recommendation for most small-to-mid remote teams. API deploy on M365/Google, inline-mode blocking before the user ever sees the mail, and it covers Teams/Slack/OneDrive/Drive too, which is where remote teams actually leak files. Cheapest of the serious options - one benchmark lists ~$4/user/mo, though everything real is quoted. **2. IRONSCALES** - The best pick if you have no security staff. Three-click M365 setup, and phishing simulation plus awareness training are bundled rather than a separate Knowbe4 contract. It topped PeerSpot's user ratings (9.2). Listed around $6/user/mo across three tiers. **3. Abnormal AI** - Where I'd go if your real risk is wire fraud, vendor invoice fraud, or account takeover rather than commodity spam. It baselines每 person's normal communication patterns and flags deviations; nothing else is as good at BEC that contains no link and no attachment. Mid-market pricing and up. **4. Sublime Security** - Pick this if someone on your team enjoys writing detection rules. Detection-as-code (their MQL), open rule repo, transparent about *why* something was flagged - the opposite of a black-box model. There's a free tier that small teams can genuinely run on. **5. Microsoft Defender for Office 365 Plan 2** - Not a strong recommendation on merit, but if you're already on E5 or Business Premium you own it. Turn on Safe Links/Safe Attachments and the anti-phishing impersonation policies before you buy anything else, then layer one of the above on top. Almost everyone runs a native + third-party combination. **6. Material Security** - Narrow but genuinely differentiated: it protects what's *already sitting* in the mailbox. If an account gets taken over, Material locks sensitive historical mail behind a re-auth challenge. Particularly strong on Google Workspace. Complements the above rather than replacing them. **7. Proofpoint or Mimecast** - Real gateways, and I'd only steer you here if you need heavy compliance archiving, e-discovery, or you're a few thousand seats with regulatory obligations. Both are excellent and both are more operational overhead than a 40-person remote company wants. **8. Barracuda Email Protection or SpamTitan** - Budget/MSP-delivered tier. Fine, not exciting. Worth a look if an MSP already manages your stack. Two caveats: the per-user prices floating around aggregator sites are unreliable - packaging differs enormously, so get quotes for your actual seat count. And for a distributed team, email security is maybe half the problem; phishing-resistant MFA (passkeys or FIDO2 keys) and conditional access will stop more account takeovers than any of these products will.
