As described on Microsoft Marketplace.
Sentaro stops the AI-driven fraud that looks like normal work
AI-generated phishing, business email compromise, and executive impersonation now mimic real business communication and slip past native filters. Sentaro connects once to Microsoft 365 and turns signals from across your business environment into one AI Behavioral Defense, powered by Sentaro's own models, each purpose-built for its layer and trained and developed in-house, so you catch what looks normal but isn't.

Sentaro deploys via the Microsoft Graph API in minutes. No MX record changes, no new gateway, and no disruption to mail flow. Sentaro runs alongside Microsoft Defender rather than replacing it.
Message Defense, live today across Microsoft 365
- Detect. AI scoring on every inbound email - header signals, sender context, content intent, and behavioral history - analyzed in milliseconds.
- Classify. Phishing, BEC, executive impersonation, spoofing, vendor compromise, and account takeover (ATO) signals that traditional secure email gateways miss.
- Explain. Every email is labeled Threat, Suspicious, or Safe inside Outlook, with the sender reputation, suspicious text, and behavioral anomalies behind the label shown in plain language.
- Respond. Threats are flagged inline within seconds - on desktop, on mobile, and on private devices, worldwide.
Three more defense layers, rolling out through 2026
- App Defense. Discovers every SaaS app, AI tool, and OAuth grant in use across the organization, scores each app's threat level, identifies which AI engine and LLM it runs on, monitors for breaches, and generates an incident report on the impact to your organization.
- Domain Defense. Monitors leaked and exposed credentials tied to your company domains before attackers use them.
- Behavioral Defense. Builds context across users, teams, and channels to flag abnormal behavior and account misuse.
One integration, four layers, and a dedicated model behind each one, purpose-built for the threats that layer has to catch and developed in-house by Sentaro.
Built for regulated and resource-constrained security teams
- 100% EU data residency with zero cross-border data flow.

Unknown means this listing does not publish a repository. It is not a statement that the code is closed, and a linked repository is not a claim that the publisher wrote it: the registry computes that relationship privately and does not publish it.
Evidence risk is the share of the build you cannot see before you deploy, not a security rating. Sign in to see the layer-by-layer basis for this band.
