PatchAnalyzer by PointSecure Technologies is a free patch analysis application for OpenVMS systems. It compares installed OpenVMS patches to those available from HP to identify vulnerabilities from outdated patches. PatchAnalyzer investigates OpenVMS systems, presents a list of installed patches, and provides a list of patches currently available from HP. Users can compare these lists to determine if their systems require updating. The software also generates a list of products and licenses installed on the user's OpenVMS systems.
