Email is still the number one attack path. Senserva checks whether your Exchange Online protections are actually turned on and tuned.
Exchange Online and Defender for Office 365 offer strong email protection, but the defaults are not the recommended settings, and policies drift. Senserva audits your anti-phishing, anti-malware, anti-spam, and Safe Links configuration against best practice and compliance baselines.
Demo and Game Mode run free, no registration, no access to your tenant. Windows and Mac.

Senserva runs standalone for full Microsoft 365 posture across configurations, logs, and CVEs, or right alongside Exchange Online.
| What Exchange Online does well | Where teams want more |
|---|---|
| Mature anti-phishing, anti-malware, and anti-spam engines. | Default policies are weaker than the recommended configuration, and few teams revisit them. |
| Safe Links and Safe Attachments protection (with the right licensing). | Hard to confirm every protection is enabled, scoped, and prioritized correctly. |
| Granular transport rules and mail-flow control. | No native mapping of email settings to compliance controls. |
| Deep integration with the rest of Microsoft 365. | Findings live separately from the rest of your posture. |
| Capability | Exchange Online | Senserva |
|---|---|---|
| Verifies protections are enabled and tuned | Manual | Native checks |
| Best-practice baseline comparison | Limited | Native |
| Compliance mapping | No | MCSB, CISA SCuBA |
| Unified with identity and device posture | No | Yes |

Senserva builds a complete, structured Microsoft 365 security dataset, configuration, identity, devices, logs, CVEs, and compliance mappings, as one connected graph, and opens all of it to the AI of your choice through the Claude MCP and the Senserva SDK. Bring your own model, there is no AI markup. Point Claude, or any AI you run, at the whole dataset and it can audit, threat-hunt, explain, and remediate from your real findings, not a vendor summary.
That is the part most tools do not give you. Many have no AI at all, or a closed built-in assistant you cannot point at your own model, or they keep their findings in a dashboard you cannot query. Where a tool does expose its data to your AI, Senserva runs right alongside it and adds the rest of the Microsoft 365 picture. Either way, the data stays with you, nothing is locked in a vendor cloud.
The majority of breaches start in the inbox: phishing, business email compromise, and malicious attachments. Exchange Online Protection (EOP) is the built-in first line, with Microsoft Defender for Office 365 adding Safe Links and Safe Attachments to detonate URLs and files before users reach them. The protection is only as good as the policy: default policies are deliberately permissive, and custom anti-phishing, anti-spam, and anti-malware policies are where real tuning happens.
Stopping spoofing of your own domain depends on three DNS-based standards. SPF lists who may send for your domain, DKIM cryptographically signs outbound mail, and DMARC tells receivers what to do when SPF or DKIM fail and where to send reports. A DMARC policy stuck at p=none, or missing DKIM, leaves the door open to impersonation. Getting all three to enforcement is one of the highest-value, lowest-cost email hardening steps.
Beyond filtering, the configuration around mailboxes is a frequent weak spot: external auto-forwarding that quietly exfiltrates mail, overly broad mailbox delegation and full-access permissions, transport rules that bypass filtering, and legacy authentication protocols (POP, IMAP, basic auth SMTP) that cannot enforce MFA. These are the settings attackers abuse after an initial compromise to maintain access and move mail.
Frameworks from CIS to the CISA SCuBA Exchange Online baseline call out the same controls: enforce DMARC, disable legacy auth, block auto-forwarding, and turn on Safe Links and Safe Attachments. Treating these as a checklist mapped to the standard you answer to makes email both safer and easier to audit.
No. Defender enforces email protection; Senserva verifies it is configured to best practice and maps it to compliance, alongside the rest of your tenant.
No agents and no cloud service. Senserva reads your tenant through Microsoft's APIs and runs on Windows or Mac. You can explore the whole product first on the free Advanced Microsoft 365 Security Simulator, with no access to your environment at all.
Yes. The Advanced Microsoft 365 Security Simulator and the game let you explore a full scan, the findings, the AI, and the reports for free. Scanning your own tenant takes a free registration, which unlocks 2 tenants with up to 25 users each, and education institution and nonprofit discounts are available.
Yes. It supports multi-tenant and MSP fleets, with bulk tenant security audits and unified, client-ready reporting across many customers.
Senserva is built for AI from the ground up and also runs fully without it. Turn it on for AI-enhanced reports and to run the product from Claude, or the AI of your choice, via our market-leading MCP. You bring your own model, so there is no AI markup, and the rich data model keeps calls and cost low.
