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

Brands named, in the order the engine gave

1. Microsoft mentioned
   If your team is on Microsoft 365 or Google Workspace, the better fit is API-based "integrated cloud email security" (ICES) that plugs into the mailbox, deploys in minutes without MX changes, and can claw back messages after delivery - which matters because remote workers get hit by internal-to-inter
2. Microsoft 365 mentioned
   If your team is on Microsoft 365 or Google Workspace, the better fit is API-based "integrated cloud email security" (ICES) that plugs into the mailbox, deploys in minutes without MX changes, and can claw back messages after delivery - which matters because remote workers get hit by internal-to-inter
3. Google mentioned

5. Abnormal recommended
   Abnormal Security - My default recommendation for a remote team of any real size.
6. Microsoft Defender mentioned
   Microsoft Defender for Office 365 (Plan 2) - If you're on M365 and anywhere near E5 licensing, turn this on before buying anything else.
7. Defender mentioned
   Microsoft Defender for Office 365 (Plan 2) - If you're on M365 and anywhere near E5 licensing, turn this on before buying anything else.
8. SharePoint mentioned
   It's effectively already paid for, covers Safe Links/Safe Attachments across Teams and SharePoint (not just email), and gives you automated investigation.
9. Check mentioned
   Check Point Harmony Email & Collaboration (formerly Avanan) - The best pick if you want one vendor covering email plus Slack, Teams, and OneDrive, which is where remote work actually happens.
10. Avanan mentioned
    Check Point Harmony Email & Collaboration (formerly Avanan) - The best pick if you want one vendor covering email plus Slack, Teams, and OneDrive, which is where remote work actually happens.
11. Slack mentioned
    Check Point Harmony Email & Collaboration (formerly Avanan) - The best pick if you want one vendor covering email plus Slack, Teams, and OneDrive, which is where remote work actually happens.
12. IRONSCALES mentioned
    IRONSCALES - Where I'd point a smaller remote team (say, under 200 people) with no dedicated security staff.
13. Material mentioned
    Material Security - Narrower but genuinely differentiated: it protects the archive, not just inbound mail.
14. Proofpoint mentioned
    Proofpoint - Still the enterprise answer for large, compliance-heavy orgs, with the deepest threat intel and best-in-class DLP and encryption.
15. Mimecast mentioned
    Mimecast - Worth a look if archiving and retention compliance are first-class requirements alongside security;
16. Barracuda / SpamTitan mentioned
    Barracuda / SpamTitan - The budget tier.
17. SpamTitan mentioned
    Barracuda / SpamTitan - The budget tier.

The answer, as recorded

For a fully remote team, the honest headline first: you probably don't want a *gateway*. Traditional SEGs sit in front of your MX record and were built for on-prem mail. If your team is on Microsoft 365 or Google Workspace, the better fit is API-based "integrated cloud email security" (ICES) that plugs into the mailbox, deploys in minutes without MX changes, and can claw back messages *after* delivery - which matters because remote workers get hit by internal-to-internal phishing and account-takeover follow-ons that a perimeter gateway never sees. Here's who I'd actually name, in order: 1. **Abnormal Security** - My default recommendation for a remote team of any real size. API-native, behavioral AI that baselines who normally emails whom, so it catches payload-less BEC and vendor-impersonation - no link, no attachment, nothing for a gateway to scan. Strongest in the category for social engineering, which is the threat remote teams actually lose money to. 2. **Microsoft Defender for Office 365 (Plan 2)** - If you're on M365 and anywhere near E5 licensing, turn this on before buying anything else. It's effectively already paid for, covers Safe Links/Safe Attachments across Teams and SharePoint (not just email), and gives you automated investigation. It won't catch the subtlest BEC - hence layering something from this list on top - but starting elsewhere while leaving Defender unconfigured is a common and expensive mistake. 3. **Check Point Harmony Email & Collaboration (formerly Avanan)** - The best pick if you want one vendor covering email *plus* Slack, Teams, and OneDrive, which is where remote work actually happens. API-based, inline-before-inbox mode available, no MX change. Also the natural choice if you already run Check Point elsewhere. 4. **IRONSCALES** - Where I'd point a smaller remote team (say, under 200 people) with no dedicated security staff. Sits at the mailbox level in M365 or Workspace, and its real differentiator is turning user reports into automatic cluster-wide remediation - so one sharp employee's report protects everyone. Bundled phishing simulation and training too, which consolidates a second line item. 5. **Material Security** - Narrower but genuinely differentiated: it protects the *archive*, not just inbound mail. It locks down sensitive historical messages behind step-up auth so a single compromised remote account doesn't hand an attacker years of W-2s, contracts, and password resets. Great as a second layer; not a complete email security stack on its own. 6. **Proofpoint** - Still the enterprise answer for large, compliance-heavy orgs, with the deepest threat intel and best-in-class DLP and encryption. For a small remote team it's overbuilt and over-administered, but I'd name it the moment auditors or a 1,000+ headcount enter the picture. 7. **Mimecast** - Worth a look if archiving and retention compliance are first-class requirements alongside security; it rates well with practitioners and the combined security-plus-archive bundle can be cheaper than buying both. 8. **Barracuda / SpamTitan** - The budget tier. SpamTitan in particular is the pragmatic choice for a very small remote team that needs solid spam and malware filtering cheaply. Don't expect sophisticated BEC detection at this price point. Practical shape of a good setup: native Defender or Workspace protections configured properly, plus **one** API-based layer (Abnormal, Check Point, or IRONSCALES depending on size and budget). Also enforce SPF, DKIM, and DMARC at `p=reject` - free, and it stops people spoofing *your* domain at your own distributed staff, which no gateway purchase does for you.
