Managed add-on · Works with any plan

Stop the bad email before anyone clicks it.

Email is still the way most attacks get in. Advanced Mail Filter sits in front of your Microsoft 365 mailboxes and inspects every inbound message for spam, malware, malicious links and impersonation attempts, so the dangerous ones never reach your team.

What you get

A gateway that reads every email first.

Built-in filtering catches a lot, but targeted phishing and invoice fraud are designed to slip past it. A dedicated filtering layer adds deeper inspection, impersonation detection and a managed quarantine, tuned by synfo for your business.

Spam & bulk filtering

Junk, newsletters and bulk mail handled before they clutter inboxes, with per-user control over what gets through.

Malware & attachment scanning

Attachments are scanned and suspicious files are held back, including the macro-laden documents attackers favour.

Link protection

Links are checked when the email arrives and again when they're clicked, catching pages that turn malicious after delivery.

Impersonation & BEC detection

Flags emails pretending to be your executives, suppliers or lookalike domains, the classic setup for invoice and payroll fraud.

Managed quarantine

Held messages go to a quarantine our team monitors, with simple digests so staff can release legitimate mail themselves.

Reporting

Clear reporting on what was blocked and why, ready for your next strategic review or insurance questionnaire.

FAQ

Quick questions, quick answers.

Doesn't Microsoft 365 already filter email?
It does, and it's a good baseline. Advanced Mail Filter adds a dedicated layer focused on targeted phishing, impersonation and post-delivery link checks, which is where most successful attacks come from.
Will legitimate emails get blocked?
We tune the policies to your business during onboarding and manage allow lists for key suppliers. Anything held is easy to review and release.
How is this different from DMARC & Phishing Protection?
Mail filtering protects your inbox from inbound threats. DMARC protects your domain from being spoofed to others. Most businesses benefit from both, and they work well together.
Is there any downtime when it's set up?
No. The cutover is a DNS and mail-flow change we schedule and monitor, with no interruption to sending or receiving.
