Start from the job in front of you. Essentials evidences compliance against policy, fast. Professional adds the tooling to quantify and prioritise risk across the estate. Enterprise is built for regulated, large estates that need change control, open reporting and enterprise SSO. Each tier builds on the one below, so the real question is how far along that path you are today.

Yes. The packages are additive: Professional includes everything in Essentials, and Enterprise includes everything in Professional. Moving up switches on the next set of capabilities on the same platform, with no re-implementation and nothing to migrate. Start where you are today and add capability as your needs grow.

Every package runs on the Guardian Core platform: inventory, scanning, manual change reconciliation, differencing and CIS/OOTB policy. Core is the foundation; Professional and Enterprise extend it. Whichever tier you pick, the underlying platform is the same.

Buy à la carte when you need one capability rather than a whole tier. Every module is available as a standalone add-on to Guardian Core, from risk and vulnerability scanning to service management and AI change control. The packages group the modules most teams adopt together. If you only need the one thing, take the one thing.

Guardian ingests data from ServiceNow and Freshservice CMDBs, and from AWS and Azure. Automated change reconciliation works with ServiceNow or FreshService and can raise incidents directly. For identity, Enterprise supports Entra ID SSO, LDAP and per-user API keys.

It is the Enterprise capability that tracks what actually changes across your estate. File Integrity Monitoring (FIM) detects change at the file level, AI change reconciliation matches what changed against what was approved, and every event is logged. The result is a record of change you can put in front of an auditor.

Guardian ships with CIS benchmarks and out-of-the-box policy packs, reports against them, and tracks how your compliance posture trends over time. Professional adds custom reporting, so you can evidence the policies your auditors ask about. You see where the estate stands at any point, not just at audit time.
