Google Cloud VM Manager vs Tenable Patch Management

Google Cloud VM Manager manages operating systems across Windows and Linux VM fleets running on Compute Engine. Its tools cover patch management, OS inventory and OS policies. Patch jobs apply updates on demand or on a schedule, report compliance, and can use selected approvals and pre- or post-patching scripts. OS inventory collects hostnames, OS and kernel versions, installed packages, available updates, Windows applications and OS vulnerabilities. OS policies centralize software configuration deployment, maintenance and reporting. Teams can use the Google Cloud console, Google Cloud CLI or OS Config API; Terraform can extend scope across projects. The service supports projects inside VPC Service Controls perimeters, but patch jobs operate on VMs in one project at a time. A free tier covers 100 VMs per Cloud Billing account per month, and limited-functionality mode is available at no cost for unlimited VMs. After the free tier, the listed charge is $0.003 per hour per VM with an active OS Config agent.
