Stop the threats that get past the filter.
Quaragate connects to Microsoft 365 with an app-only grant and uses AI to triage every message after delivery, quarantining phishing, business email compromise, and malware across all of your mailboxes. No MX changes. No mail rerouting.

Native filtering checks mail once, at the door.
Microsoft 365 and most secure email gateways score a message at the moment of delivery, then move on. But verdicts change. A link that was clean at delivery gets weaponized an hour later. A compromised vendor account starts sending convincing invoices. The dangerous mail is already sitting in your users' inboxes, and nothing is looking at it anymore.
Threats land first, detonate later
Delayed-weaponization links and time-shifted payloads sail past a one-time check at delivery.
Trusted senders get compromised
Account takeover and vendor fraud come from real, authenticated mailboxes that pass SPF, DKIM, and DMARC.
Gateways add risk and rerouting
MX-based products sit in the delivery path. A misconfiguration or outage there can hold up every email you send and receive.
Three steps, no mail-flow changes.
1. Connect
Grant a least-privilege, app-only connection to Microsoft Graph and Exchange Online. No DNS or MX records change.
2. Triage
AI classifies and scores every delivered message, learns each tenant's normal behavior, and re-checks mail as new signals arrive.
3. Quarantine
Malicious mail is pulled from the inbox automatically, with a full audit record of what was found and why.
Detection and remediation that keep working after delivery.
Inbox-level AI triage
Every delivered message is classified and scored against a per-tenant behavioral baseline, not a static global ruleset.
Automatic quarantine and clawback
When a verdict turns malicious, Quaragate removes the message from the mailbox it already reached and records the action.
BEC, phishing, and malware coverage
Impersonation, credential phishing, QR-code attacks, account takeover, and malicious attachments, mapped to named threat types.
Multi-tenant by design
Strict per-tenant isolation so one customer's mail and verdicts are never visible to another, with one console across them all.
