AWS Resource Discovery is a free cyber asset attack surface management tool. Axonius Unified Device Observability is a commercial cyber asset attack surface management tool by Axonius. Compare features, ratings, integrations, and community reviews side by side to find the best cyber asset attack surface management fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Teams building an initial asset inventory across sprawling AWS accounts should start with AWS Resource Discovery because it discovers what you actually have before you can defend it, and the free price tag means zero friction to run it today across dev and prod environments. The tool catalogs resources in JSON format via botocore, giving you the raw material to feed into downstream CSPM or CIEM tools rather than replacing them. Skip this if you need continuous monitoring or remediation workflows; it's a one-time discovery pull, not a persistent control plane.
Axonius Unified Device Observability
Healthcare IT and clinical engineering teams managing sprawling medical device fleets will get the most from Axonius Unified Device Observability because it actually classifies devices by protocol and clinical function rather than treating them as generic assets. The platform ingests from CMMS, EHR, RTLS, and network telemetry simultaneously, giving you a single authoritative record of 150+ device attributes that most asset tools simply cannot correlate. Skip this if your priority is incident response automation; Axonius prioritizes continuous monitoring and asset classification over playbook execution, making it stronger on the ID and DE functions than PR.IR.
