Guardian vs the alternatives

For regulated hybrid estates that want continuous drift detection and change reconciliation without a heavy services programme, Guardian is the closest like-for-like alternative. Tripwire Enterprise has the larger policy library (Fortra publishes 4,000+ policy and platform combinations). Guardian ships CIS Benchmarks and out-of-the-box policy, reconciles every detected change against ServiceNow, Freshservice, Ivanti Neurons or BMC Helix, and is sold in three tiers so you can start with Essentials and add capability later.

Both detect configuration change and reconcile it against approved change requests. Netwrix Change Tracker is a file integrity monitoring and hardening tool with 250+ CIS-certified reports. Guardian is built around an independent record of actual state across servers, end-user computing, network, cloud and containers, reconciled against your ITSM, with compliance evidence for FCA, SOX, DORA, NIS2 and GDPR.

Evolven leads with patented AI risk scoring and a CI/CD risk gateway, which suits DevOps-heavy teams. Guardian leads with audit evidence: embedded CIS Benchmarks, bespoke policy, and continuous reporting mapped to the frameworks regulators ask about. Guardian Enterprise adds AI change reconciliation and AI compliance on top. If your first question is what will the auditor accept, start with Guardian.

No. Guardian checks your CMDB rather than replacing it. ServiceNow holds the record of what is expected to be true. Guardian captures what is actually running and reconciles the two, flagging every change that has no matching approved change request. Most Guardian customers run it alongside ServiceNow, Freshservice, Ivanti Neurons or BMC Helix.

Guardian keeps a record of actual configuration state that is independent of the supplier's own tools and reports. Every change, whoever makes it, is captured at line level and checked against its approved change request, so you can verify supplier reports rather than rely on them. That supports third-party oversight duties such as DORA Article 28, under which financial entities remain fully responsible for compliance even when an ICT provider runs the service.

IaC drift tools compare live cloud resources with the Terraform, Pulumi or CloudFormation code that defined them, and the newer platforms also discover cloud resources created outside code. They stay inside the cloud accounts. Guardian covers the rest of the estate as well: on-premises servers, end-user computing, network devices and hybrid workloads with no IaC definition, and it produces the compliance evidence that IaC tools are not designed to provide.

Pulumi Discovery & governance audits cloud resources against policy packs such as CIS, NIST, HITRUST and PCI DSS, and its AI agent, Neo, writes fixes as infrastructure code. It suits platform teams who run their cloud through Pulumi. Guardian covers the wider hybrid estate, reconciles every change against approved change requests in ServiceNow, Freshservice, Ivanti Neurons or BMC Helix, and provides evidence to support FCA, DORA, NIS2, SOX and GDPR reporting. It also stays independent of the tooling that deploys and fixes your infrastructure.

Usually, yes, because the two answer different questions. Wiz is a cloud security platform that ranks misconfigurations, vulnerabilities and identity risk by how exploitable they are. Guardian tracks what changed across the whole estate, including physical servers, end-user computing and network devices, checks each change against its approved change request, and turns the result into audit evidence. The two work well side by side.

Configuration drift is the gradual divergence between how a system is supposed to be configured and how it is actually configured, caused by emergency fixes, manual edits and changes made outside the approved process. It matters because regulators ask you to prove that every change was authorised. Uptime Institute's 2026 outage analysis found configuration and change management failures were the leading cause of network-related outages.

DORA applies to EU financial entities and its regulatory technical standard on ICT risk management (Article 17) requires a change management procedure covering all changes to software, hardware, firmware, systems and security parameters. SOX, PCI DSS, NIS2, ISO 27001 and FCA operational resilience rules carry similar expectations. Guardian produces continuous evidence against these, rather than a point-in-time snapshot.

Guardian detects and reconciles drift, then routes the fix through your existing change process, raising incidents in your ITSM tool where needed. That is deliberate: in a regulated estate, an unapproved automatic change is itself a compliance event. Where you want automation, Guardian can trigger actions in other systems through its API.

Yes. Guardian Essentials comes with a 30-day free trial, so you can scan your own servers, see drift against a known-good baseline and run CIS Benchmark reports on real systems before you commit. If you want to compare Guardian with a tool you already run, book a 30-minute call with the Guardian team.

Guardian does not run active network discovery. It works from agents, the agentless Connection Manager, a node list, or data imported from ServiceNow or Freshservice CMDBs and from AWS and Azure. Your existing discovery tooling stays the source of what exists; Guardian becomes the source of how it is configured and whether each change was approved.
