Common questions
Guardian360 vs Greenbone / OpenVAS, answered
Is Guardian360 like OpenVAS?
Guardian360 uses multiple scan engines under the hood, but unlike a DIY OpenVAS deployment it is fully managed, agentless and maps findings to 25+ frameworks, with nothing for you to host.
Do I need to host anything with Guardian360?
No. Scanning runs from the central EU-hosted platform; an internal network only needs a lightweight Probe appliance.
