- Product updates - updates to the agent itself. Ensures that agents are running with the latest updates as released by GFI
- Threat definition updates - vulnerability definitions that enable agents to detect the latest threats as soon as they are detected and fixed by software vendors
- Security updates - missing third-party and system, patches and service packs detected on a target computer
GFI LanGuard merges Product and Threat Definition updates and are handled as a single entity; separately from Security updates.
