Microsoft security, multiplied
Everything your Microsoft environment already knows about your security posture - surfaced, explained, prioritized, and fixed. In minutes. Not months.
Siemserva: 612 checks across your Microsoft 365 environment. Most organizations running Microsoft 365 are better protected than they realize - and more exposed than they know. Siemserva shows you both. It surfaces every security signal your environment is already generating, maps each finding to CISA SCuBA and MCSB framework controls, and delivers clear next steps - engineer-written fix guides and AI-generated PowerShell remediation tailored to your tenant. Six report types. Free for organizations up to 100 people. One file - download and run.
Why we exist. Our mission is to bring enterprise-grade security and IT management to every organization that needs it - regardless of team size, budget, or technical depth. Most organizations already have serious security tools. What they don't have is the time or budget to get the full value from them. Security teams are stretched thin. IT teams are stretched thinner. Some organizations don't have dedicated IT staff at all - yet every one of them needs to be secure. That's not a failure of effort. It's a resource reality, and the security industry has never built for it honestly. Senserva was. Our core tools are free for organizations up to 100 people. We work with Microsoft MVPs and technical community leaders to multiply our reach. We support nonprofits with direct access. We hold ourselves to one standard: build the most powerful tools available and make sure anyone can use them.
Enterprise-grade capability. No enterprise required. Mark Shavlik has been solving this category of problem for a long time. The patch management technology he built at Shavlik Technologies - acquired by VMware - remains the most widely deployed patching solution in the world. While Mark is no longer involved with that technology, the same instinct that created it drives everything Senserva builds: serious tools, engineered to work for everyone.
"For years I watched the same thing happen. Organizations buy the right tools, configure them as best they can, and still get breached - not because the tools failed, but because nobody could see what the tools were already finding. The signal was there. It just needed someone to surface it, explain it, and say: here's what to do. That's what Siemserva does. And it turns out, that changes everything."

You're Not Crazy. This Shouldn't Be This Hard.
Let's talk about the elephant in the room. You bought Microsoft 365. Maybe E3, maybe E5. You were told you'd get "enterprise security." And technically, you do. It's all there in your license.
But here's what they didn't tell you:
You need to configure 100+ security policies across Defender, Entra, Intune, and Purview. Each one has dozens of settings. Many conflict with each other. Documentation is scattered across thousands of pages. And it changes every month.
You need to monitor 15+ different Defender products. Defender for Endpoint. Defender for Identity. Defender for Office 365. Defender for Cloud Apps. Each with its own console, its own alerts, its own logic.
You need to track compliance frameworks that require evidence you can't easily produce. Your cyber insurance wants proof. Your auditors want documentation. Your board wants assurance. And the frameworks keep multiplying. Each one wants you to map your security posture to their specific requirements. That's weeks of work. Every quarter. Forever.
This isn't a failure of effort. It's a failure of the industry.
Senserva monitors all of it. Siemserva runs 612 security checks across your entire Microsoft environment, streams findings live as the scan runs, and explains every one in plain English - what's wrong, why it matters, and exactly what to do. AI analysis built from real-world pattern recognition across thousands of environments surfaces the gaps that settings dashboards miss, maps each finding to CISA SCuBA and MCSB controls, and generates the PowerShell to fix it.
The Vendors Forgot About You
The security industry has a dirty secret: they don't build for you.
Every major security vendor builds for the Fortune 500. They build for companies with 50-person security teams, seven-figure budgets, and dedicated compliance departments. They build complexity because enterprise buyers equate complexity with capability.
Then they "downmarket" those same products to you. Same complexity. Same assumptions. Same expectations that you have unlimited time and expertise. Just a smaller price tag and fewer features.
That's not a solution. That's a gap waiting to be filled.
Microsoft builds incredible security technology. Defender alone has capabilities that would have cost millions a decade ago. But Microsoft builds for everyone, which means they can't hold your hand through implementation. They give you the tools. What you do with them is up to you.
Until now.
Senserva bridges the gap. The same capability that large organizations get from dedicated security teams - continuous monitoring, compliance mapping, AI-powered analysis, automated remediation - available to every organization, without the team required to run it. First scan in minutes. Subsequent scans in seconds. Or run continuously in SIEM mode, 24/7.
What Senserva Actually Delivers
Enterprise-grade security and IT management, without the enterprise overhead. Here's what that looks like in practice.
We support companies of all sizes. But we have a unique focus: Security Management for the Rest of Us. Taking advantage of advanced technology from us and our partners like Microsoft to create a product with all that power - and none of the headaches.
Use What You Have
You already own Microsoft security. Siemserva audits 612 checks across Entra ID, Exchange, SharePoint, Teams, Intune, and more - no agents to deploy, no complex setup. Just run it and see exactly what needs fixing.
Six Reports, Six Audiences
One scan produces six distinct reports: Detailed (for your sysadmin), Compliance (for your auditor), Business Focused Review (for your CFO), and Remediation (for whoever has to fix it). And more. Every report is a self-contained HTML file. Print to PDF in one click.
AI That Explains the Why
Press A on any finding and get a plain-English AI response tied to your actual scan data. Ask why PIM security matters and get an answer that references your specific environment - not a generic Wikipedia definition. Your Anthropic API key, your data, your analysis.
This isn't about adding another tool to your stack. It's about finding and SOLVING problems.
Security Software You'll Actually Want to Use
Most security software is miserable to use. Clunky interfaces, jargon-filled reports, hours of configuration before you see any value. .
We built the opposite.
Siemserva starts in minutes. Findings stream live as the scan runs. Subsequent scans take seconds. And here's the part that surprises people: it's genuinely satisfying to see exactly where you stand - what's solid, what needs attention, and exactly what to do about it.
Minutes, Not Hours
First scan: 5-10 minutes for most environments. Subsequent scans: often seconds, thanks to delta detection. SIEM mode runs continuously on a 30-minute cycle. No waiting for a final report - findings stream live as the scan runs.
Dual Risk Scoring
Every scan produces two scores: a deterministic heatmap score computed directly from your findings (objective, repeatable), and an AI Risk Assessment that factors in attack chains, blast radius, and privilege exposure. The AI score can never fall below the deterministic score. You get both - and you can show both to leadership.
PowerShell Generated for You
On the Remediation tab, press P. Siemserva sends your findings to Claude and gets back an executable .ps1 script - sorted by severity, using the Graph PowerShell SDK, with -WhatIf support and error handling built in. You review it. You run it. Humans stay in control.
That's not a feature. That's a different philosophy

Built by Someone Who Gets It
Mark Shavlik
Founder, Senserva
Mark Shavlik isn't new to this. He built Shavlik Technologies, the company that pioneered patch management and was acquired by VMware. He's spent 30 years in the trenches of IT security, and he's seen the same pattern repeat over and over.
"For years I watched the same thing happen. Organizations buy the right tools, configure them as best they can, and still get breached - not because the tools failed, but because nobody could see what the tools were already finding. The signal was there. It just needed someone to surface it, explain it, and say: here's what to do. Siemserva does that. And it turns out, that was the only thing that mattered."
This isn't a startup chasing trends. It's a team with deep technical roots and a straightforward belief: every organization deserves the same quality of security intelligence as the ones that can afford a full team to produce it.
But here's what Mark's most proud of: people actually want to use Senserva. They don't dread it. They run assessments, show colleagues, and tell their IT friends. After 30 years of building security software that people had to use, he finally built something people choose to use. That's the real breakthrough.
