This is currently freeware (for home use) and from a quick glance seems like it has most things covered. I installed on my home laptop, started a scan and after around 5 mins it had detected that my install of Wireshark (you don’t generally get 3rd party patching products picking up on this type of software) was out of date! Brilliant, and all for free.
As far as the patching side of things goes you’re provided with a link to the latest installer but the PSI freeware doesn’t seem to include any kind of automation, quite understandable as it’s not a corporate product. If you do wish to use this in a corporate environment there is the option to integrate PSI 2.0 with their CSI product, obviously for a fee.
Well worth a look!
