AI-Native Detection
Read intent, not just links.
- Analyze sender identity, language, and intent with LLMs to catch BEC and social engineering
- Detect payload-less attacks with no link or attachment for a gateway to scan
- Catch vendor email compromise and invoice fraud from trusted, legitimate senders
Automated Remediation
Pull threats from every inbox at once.
- Quarantine malicious messages across all affected mailboxes in a single action
- Contain threats automatically, or hold actions for analyst approval
- Investigate every email alert alongside endpoint, identity, and cloud data

Beyond the Inbox
The whole email attack surface, one console
Mailbox Takeover
Catch compromised mailboxes fast
Flag anomalous logins, risky OAuth grants, and inbox rules that hide replies or forward mail to attackers. Revoke sessions the moment an account turns hostile.
Outbound Data Protection
Keep sensitive data inside
Classify outbound email and cloud shares by content and context, and block PII, financial, and regulated data before it leaves.
Reporting & Simulation
Turn every user into a sensor
A one-click report button in Outlook feeds live detection, while LLM-driven phishing simulations and training raise resilience.
API Deployment
Live in minutes, no MX changes
Connect through Microsoft Graph and Google APIs. Messages are scanned post-delivery, layered on top of the gateway you already run.
