A former member of the Microsoft Windows NT Kernel team, Mark created HFNetChk and MBSA for Microsoft, and his team built the SMS 2.0 SUS Feature Pack. Mark and his team developed core patch management technologies that were later used in Windows Server Update Services (WSUS). He founded Shavlik Technologies, one of the industry's leading patch management companies, and sold it to VMware; the patch model he designed is still in use in many major patching products.
Too many patches are still applied by hand, while AI-driven attacks move faster than any manual process. Senserva's goal: make patching faster, easier and much more reliable.
Senserva 360 Patch+ finds what your machine is missing, patches it, removes what you do not want and fixes basic security settings, with a click. Free on this machine. From the team that built Microsoft's first patch scanners, HFNetChk and MBSA, now rebuilt with AI agents for Windows, macOS and Linux. AI-enhanced, not AI-dependent: every scan and install works without AI; the agents make it better.

One app for the machine in front of you. Scan it, see what is missing worst first, then act on what you choose.
Scan this machine and see every missing Microsoft and third-party update, with exploited vulnerabilities first. The same scan checks basic Windows security settings, such as SMBv1, UAC, LSA protection, the firewall and PowerShell 2.0.
Install the missing app updates with Senserva's verified installers, after one administrator prompt. It first checks why updates fail on this machine, and it never restarts on its own. A rescan proves the result. It installs third-party app updates on Windows; Microsoft's own updates stay with Windows Update.
Remove software you no longer want. You pick what goes.
Fix a basic security finding with a click, then the check runs again to confirm the fix.
Scanning the machine Patch+ runs on is free, and so are Patch It, Remove It and Fix It on that machine. Patch data checks need registration.
Missing patches are half the picture. Patch+ checks the basic security settings on the machine it runs on, in the same scan as patches, and Fix It corrects a finding with a click.
Patching should fit around your work and around the rules your organization already set.
When an update needs a restart, Patch+ asks before it restarts: restart now, tonight, or delay an hour, up to three times.
When Intune, Group Policy or Configuration Manager manages restarts, Patch+ leaves them to it, and shows the deadline and where it came from.
A patch with a Microsoft known issue or a Senserva Watch breakage alert is marked Warning in the report, with Microsoft's status and fix. With Patch It, such a patch is held from installing until you override it by name.
Patch+ scans and reports what is missing on every platform, and it installs products that have passed the install lab.
Windows 10 and 11, Windows Server 2012 R2 to 2025, .NET, Edge, Microsoft 365 Apps, Teams and SQL Server, plus third-party apps such as Chrome, Firefox, Acrobat Reader, Zoom, VS Code, 7-Zip, Notepad++, Java and VLC. Patch+ is one Native AOT file, and it can also scan your network or your domain, with nothing to install on the machines it scans.
A native Mac app that scans the Mac it runs on against Apple's macOS, Safari and Xcode releases and the Mac builds of apps such as Chrome and Firefox.
Local scans read the installed packages directly and are proven on Ubuntu, Debian, Red Hat, Fedora and Alpine. The p25 command-line scanner runs on Windows, Linux and macOS, with JSON output for scripts.
Linux: Debian, Ubuntu, Fedora, Red Hat Enterprise Linux (UBI) and Alpine, through each distribution's own package manager (apt, dnf, apk).
p25 as .deb, .rpm and .apk packages, with a scheduled scan.
Features and data coverage may change.
The right patch depends on the right data. Senserva's patch repository is rebuilt every day from vendor and threat sources, so a scan is checked against what vendors shipped this week, not last quarter.
Counts from the Senserva patch repository, 25 October 2026. The patch data is Senserva's: access requires registration, and free use runs against hosted data. It is not open source and not offered as a download.
Each agent has one job, a narrow set of tools, and a person who approves what it proposes. Nothing reaches your machines until it has been tested and you have said yes.
A product specialist agent per product learns how that product installs on clean, disposable lab machines before it is trusted. Chrome, Firefox, Acrobat Reader, VS Code, 7-Zip, Notepad++ and KeePass have passed the lab as the system account on Windows Server 2022.
The installer must be signed by that product's pinned publisher and pass a malware scan.
A person consents before anything installs: each one, or once by opting into scheduled patching. A patch with a threat or the wrong publisher is held for every machine until someone looks, and patches roll out in rings: a test group first, then wider.
The agent steps in: it picks one fix from a fixed list of safe actions (retry machine-wide, close the app and retry, use the other verified installer, or stop and report), your machine checks the choice against your policy, and every step is logged. It never runs a command it made up.
When a vendor source fails, an agent proposes the missing releases from the vendor's own pages after the daily build. Code re-verifies every proposal, and one reaches the patch data only after it verifies on three separate days.
A watch service over every place the repository reads. It spots new items as vendors publish them, and the silent changes too: a vendor page that changed shape while the data still looked fine. The AI proposes; code never deploys itself.
Which update replaces which is how you install only what is needed. Each product line, Firefox ESR beside Firefox or a Java release line beside the next, gets its own model, and a Supersedence agent per product proposes and cross-checks. For Microsoft, supersedence stays deterministic.
