Agentic email security
A platform of specialist AI agents that investigates suspicious email, identity threats, and phishing infrastructure, using your organization's context to help uncover what happened and what to do next.
Built for Microsoft 365 email and identity security.
More than a single-purpose scanner
Email threats often cross boundaries: a suspicious message can involve an account, a trusted relationship, or infrastructure outside your organization. Mesa brings specialist investigations together and uses relevant context to help your team see those connections.
Specialist agents
Mesa agents examine suspicious email, investigate identity activity, and trace phishing infrastructure. Each focuses on a distinct security task while contributing to a clearer picture of the incident.
Explore the capabilitiesOrganizational context
Context Hub is a continuous layer of knowledge about your people, applications, and business relationships. Agents combine incoming signals with this shared context to make decisions, and feed their findings back to continuously enrich it.

Analyze suspicious emails and support your team in understanding the evidence and appropriate response.
Identity
Investigate identity signals and activity that may be connected to an email threat or compromised account.
Phishing infrastructure
Investigate impersonation domains and prepare evidence to support phishing takedown requests.
Agentic by design
Mesa's agents gather and assess relevant evidence across the task at hand. They help connect signals and explain what they find, so your team can decide how to respond. Start with a single investigation, then add ongoing email protection when it fits your needs.
