CST VerdictBased on our analysis of core features, integrations, company size fit, deployment model, here is our conclusion:
Security teams managing large subdomain inventories who need to quickly identify third-party service dependencies will find cnames valuable for that single, unglamorous job. The tool does one thing well: bulk CNAME resolution at no cost, which means you can run it repeatedly without justifying recurring spend to procurement. This is a CLI utility, not a platform; it won't replace your external attack surface management tool, but it will save time in the reconnaissance phase before you feed results into one.
