SecPod Saner Personal is a free security tool which scans your PC for vulnerabilities and missing security patches.
Setting up the program takes longer than we expected. First, you have to register with your email address; then you're sent a link to a licence key; you have to download that file to your PC, and import it into SecPod Saner Personal before the program will launch.
Once the initial configuration is done, though, life gets much simpler. Click "Scan" and the program examines your installed software, checking for missing updates. Any problems are highlighted in a detailed report. (It doesn't just say program "x" is outdated; you actually get a list of its known vulnerabilities, and can read more about each one.)
If you're happy to update everything SecPod Saner has listed, then clicking "Remediate All" will download and launch the latest installer for each program. (These won't run silently, at least by default, so you'll need to step through each installation program as usual.) But if you need more control, individual "Fix" links allow you to update specific applications only.
Useful configuration settings help you customise how the program works. If you don't want to update everything manually, for example, you can set up SecPod Saner to run on a schedule, and apply any patches itself.
We tested all this on a Windows 8 system, and ran into one or two problems. For example, the program told us that our Python installation had one vulnerability; we clicked "Fix", it downloaded and installed the latest version, scanned again... And told us Python still had one vulnerability.
More fundamentally, SecPod Saner is supposed to check for "compliance" issues, poorly configured settings and so on, but it wouldn't do this for us. Checking the Settings page revealed it had no "definitions", but we saw no way to resolve that, and the extremely basic documentation didn't help, either.
Despite this, SecPod Saner generally worked well (especially for version 1.0), correctly picking up our outdated applications, then successfully downloading and installing the necessary fixes. There are wrinkles to be ironed out, but the program has some promise, and we'll be interested to see how it develops.
