Guardian - 2026 Pricing, Features, Reviews & Alternatives

Guardian is a cloud-based (SaaS) configuration drift detection and compliance monitoring platform designed for enterprise organisations operating in regulated and high-availability sectors. It delivers a single, independent view across an organisation's entire hybrid IT estate, continuously comparing configurations against known-good baselines to identify drift, validate approved changes, and surface unauthorised deviations in real time. Target industries include financial services (banking, insurance, capital markets), public sector (central and local government), healthcare, MedTech, and manufacturing.

Guardian monitors servers, containers, cloud platforms (AWS, Azure, Google Cloud), endpoints, firewalls, routers, switches, and SaaS solutions from a unified interface. Its agentless architecture supports 5-minute onboarding on AWS and requires no persistent agents across monitored infrastructure. Each detected configuration change is classified as matched, unmatched, or ambiguous against approved ITSM change records, with native integrations covering ServiceNow, FreshService, Ivanti Neurons, and BMC Helix. Embedded CIS Benchmark scanning, bespoke policy creation, and support for frameworks including FCA, SOX, DORA, Cyber Essentials, ISO, and ITIL allow compliance posture to be maintained continuously rather than reconstructed retrospectively. Estate segmentation by department, agency, or team supports delegated administration alongside central oversight.

Guardian maintains a durable, timestamped, and attributed audit trail for every configuration change, giving compliance teams and regulators on-demand proof of configuration state at any point in time. This replaces legacy file integrity monitoring tools and reduces analyst hours spent on audit preparation. Guardian is listed on G-Cloud 14 and is available via free trial.
