Install Siemserva by Senserva with your morning coffee. Key issues fixed before lunch. Sleep well at night.

The biggest risks are the ones nobody noticed. Know your Microsoft 365 security gaps. Fix the high-priority ones, fast. Prove you are compliant. Save up to 80% of your security management time.

Siemserva by Senserva scans your Microsoft 365, Intune, Entra ID (logs included), CVEs, and Purview tenant, surfaces what matters, and helps you remediate it, whether you run a single tenant, multi-tenant, or MSP fleet. That means Intune compliance auditing, Entra configuration auditing, and continuous tenant monitoring in one Entra ID security scanner. MSPs cut security management time across every client tenant, standardized and run from one place. Works Great for MSPs, saving time and helping you solve all the difficult problems. It is built on three decades of Microsoft security heritage from founder Mark Shavlik.

Fast, deep scans. Powerful reporting. AI enhancements that matter. 650+ deterministic checks across your whole tenant in minutes, mapped to key frameworks and audit-ready on the first scan, with AI-enhanced reports and AI created, Siemserva validated remediation that cuts hardening time dramatically. The depth of a security team at the speed of one command.

up to 80%

less time spent on Microsoft 365 security

Teams report cutting Microsoft 365 and Azure hardening time by up to 80 percent with Siemserva by Senserva. The reason is simple: it replaces manual, multi-console, PowerShell-driven audits with one command that finds and fixes hundreds of issues for you.

One command, not many consoles
650+ checks across your whole tenant in minutes, instead of exporting and correlating across a dozen admin portals by hand.
Remediation written for you
Every finding arrives with a validated, ready-to-run fix, so you stop researching and writing PowerShell from scratch.
Reports and evidence, automatic
Six AI-enhanced reports and audit-ready compliance evidence on every scan, instead of hours of cut-and-paste per audience.
Repeatable every time
The same scan gives the same answer, so reviews stop depending on who ran them or how much time they had.
Siemserva AI-enhanced Microsoft 365 security report

AI-enhanced reports your auditors actually read

Every scan becomes six reports, from a deep technical breakdown to a one-page executive summary, each carrying the evidence, the mapped control, and the validated fix. The AI provides new and powerful insights; the evidence makes them defensible. Self-contained HTML, print-ready for the audit binder.

Validated AI remediation, not just findings

For each finding, Siemserva generates a fix tuned to your tenant, validates it, and lets you review and apply it, often as ready-to-run PowerShell after your review, from the full Senserva UI or from Claude through the Senserva MCP. The next scan proves it worked.

How validated remediation works

Misconfigurations are half the story. Your logs are the other half.

Most posture tools stop at settings. Siemserva reads your logs too. Alongside 650+ configuration checks, it investigates your sign-in logs, the unified audit log, directory and provisioning logs, and security alerts, so you see not just the door left unlocked, but who walked through it. Risky activity surfaced, ranked, and tied to a fix.

Sign-in and risky sign-in analysis
Replays the last 14 days of sign-in activity to catch risky and out-of-policy access, legacy authentication in the wild, and accounts signing in outside any Conditional Access policy.
Unified audit log health
Confirms auditing is actually on and capturing the events your investigations and your auditors depend on, instead of failing silently.
Directory and provisioning logs
Surfaces risky changes to roles, applications, and identities, and provisioning activity that has drifted away from policy.
Security alerts, triaged
Pulls in security alerts and ranks them alongside every other finding, in one prioritized view, each tied to evidence and a remediation step.
Conditional Access gaps and bypass paths
Every Conditional Access policy is checked for the holes that matter: users and apps no policy applies to, risky exclusions left in place, legacy authentication slipping through, and report-only policies that were never enforced.
Logs, read end to end
Sign-in, unified audit, directory, and provisioning logs are read together and correlated, so risky activity is caught across all of them at once, not one console at a time.

Configuration tells you where you are exposed. Logs tell you whether it is being used against you. Siemserva does both, in one scan.

Catch configuration drift, continuously

A tenant that was secure last quarter quietly is not this quarter. Settings change, exceptions linger, and Microsoft moves defaults. Siemserva compares your live configuration against a known-good baseline on every scan and surfaces exactly what has drifted, so you can run it on a schedule and keep your modern workplace on baseline between audits. That continuous security drift management keeps misconfigurations from quietly piling up between reviews.

Baseline comparison
Every scan is measured against a secure baseline mapped to MCSB and CISA SCuBA, so drift is defined against a standard, not a guess.
Identity and role drift
Catches Conditional Access exclusions that linger, MFA quietly disabled, and Azure or Entra role assignments that drift from approved access.
Intune and device drift
Flags compliance policies, configuration profiles, and update rings that have slipped, per device and per tenant.
Run it on a schedule
With continuous scanning, drift is caught as it happens, not at the next audit, with a validated fix attached to each finding.

CVEs and missing patches, ranked by what can actually hurt you

A raw CVE list is noise. Siemserva reports the vulnerabilities and missing patches across your estate, enriches each one from the authoritative sources, and ranks them by real-world risk, so you fix the handful that matter, not the thousands that do not.

Enriched from the real sources
Every CVE is enriched from NVD, CIRCL, CISA KEV, EPSS, and Microsoft MSRC, with CVSS scores and vectors, CWE type, and exploitation status.
Ranked by exploitation, not just CVSS
Actively exploited (CISA KEV) first, then EPSS probability, severity, exposure age, and fleet impact, in a repeatable, defensible order.
In the same dashboard and reports
Missing patches surface as findings beside your configuration and log results, each with the CVEs it fixes and a KEV badge when it is being exploited.
Ask your AI for the plan
Through the MCP, ask Claude which missing patches fix actively exploited CVEs, and get a risk-tiered remediation plan from your real data, no per-CVE lookups.

How Siemserva reports on CVEs, and how AI uses them

"Senserva cut my tenant hardening effort by 80%. Setup takes minutes, results are immediate. The AI doesn't just report findings, it reasons about your environment and tells you exactly how to fix them. If you work with Microsoft 365, Intune, or Entra ID, this is the tool you didn't know you were missing."

Read-only, least privilege
Connects through Microsoft's own APIs with least-privilege, read-only access. It never changes anything on its own.
Your data stays with you
Findings live in a local database you control. Your tenant data is not shipped to us.
You stay in control
Remediation is reviewed and applied by you, never silent automatic changes.

Audit-ready, by design.

Every finding ships with the source data Siemserva used to detect it, the control mapping it satisfies (or fails), and a validated remediation step. Mapped to every major framework and the verticals your auditor cares about.

One tool, from first scan to proven fix. Designed to save you time and get more secure.

Siemserva is a Microsoft 365 security assessment tool that works the way your tenant actually does. It runs a full tenant security scan across Entra ID, Intune, Exchange Online, SharePoint, OneDrive, Teams, Microsoft Defender, Purview, Azure RBAC, and Copilot, then ranks what it finds by Severity. It is an M365 misconfiguration scanner and a hardening tool in one: it does not just list settings, it tells you which gaps put you at risk and why. It also works as an Intune compliance check tool, validating device compliance policies, configuration profiles, and update rings. From an Entra ID security audit to ongoing Microsoft 365 security posture management and continuous configuration drift management, it is one continuous workflow.

That is security posture management without the spreadsheet. Every finding carries the source data behind it, the compliance control it maps to, and a validated remediation step, so Microsoft 365 misconfiguration remediation becomes a reviewed action instead of a research project. Teams report cutting Microsoft 365 and Azure hardening time by up to 80 percent.

Work it all in the Senserva dashboard, or drive the same data from Claude through our MCP server. Either way you get automated security remediation for Microsoft 365, audit-ready evidence, and answers in plain language. See what a Microsoft 365 security check finds, or compare Siemserva with the tools you already run.
