CST VerdictFeatures, pricing, ratings, and pros and cons, compared head to head.
IVRE (Instrument de veille sur les réseaux extérieurs) or DRUNK (Dynamic Recon of UNKnown networks) is a free external attack surface management tool. Vulneri ASM is a commercial external attack surface management tool by Vulneri. Compare features, ratings, integrations, and community reviews side by side to find the best external attack surface management fit for your security stack. Independent and vendor-neutral: our scores and rankings are earned, never bought — sponsored placement is always labeled.
CST VerdictThreat hunters and red teamers with in-house infrastructure will extract real value from IVRE because it bundles passive DNS, active scanning, and data aggregation into a single framework you control entirely, eliminating vendor lock-in on recon workflows. The 3,964 GitHub stars reflect active use in offensive security circles, and the free pricing means you pay only for the infrastructure you run it on. This is not for teams expecting a managed SaaS experience or those who need hunting automation built in; IVRE requires familiarity with command-line tools and willingness to integrate data sources yourself. Mid-market and enterprise teams drowning in false positives from their current ASM tool will find real value in Vulneri ASM's exploitability validation, which actually confirms which discovered assets pose immediate risk rather than just flagging everything. The platform covers ID.AM and ID.RA functions across cloud, SaaS, and on-premises infrastructure while automating ownership assignment to cut response friction. This is not the pick for organizations needing mature vendor support or a lengthy implementation runway; Vulneri is a seven-person shop based in Brazil, so you're buying technical strength and speed over hand-holding.
Based on our analysis of core features, company size fit, deployment model, here is our conclusion:
