Context Hub

Context that improves every investigation.

Context Hub maintains knowledge about your people, apps, and business relationships. Agents combine that context with incoming signals to make decisions, then feed their findings back into the Hub.

Can I try Mesa without connecting Microsoft 365?

Yes. Submit an email or URL for a free scan. An administrator can connect Microsoft 365 when your organization is ready for ongoing protection.

Are email, identity, and takedowns separate products?

They are capabilities of Mesa Agentic Platform. Professional and Professional+ combine email protection, identity investigations, Context Hub, and a phishing takedown allowance.

What access does Mesa need?

A submitted email or URL requires no Microsoft 365 connection. Identity investigations read sign-in and directory data with administrator consent; they do not require mailbox-content access. Email protection requires mailbox permissions. Identity containment requires separate response permissions.

What can Mesa do automatically?

Email remediation follows your configured policies and plan. Takedown requests and identity containment actions require your team’s approval.

Who decides whether a phishing site is taken down?

The registrar or hosting provider decides whether and when to remove it. Mesa investigates the evidence and prepares the request for your approval. A takedown does not revoke access to an already-compromised account.
