ONYPHE vs Guardz External Footprint: 2026 Comparison
ONYPHE is a free external attack surface management tool. Guardz External Footprint is a commercial external attack surface management tool by Guardz. Compare features, ratings, integrations, and community reviews side by side to find the best external attack surface management fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams responsible for external asset discovery and exposure monitoring should start with ONYPHE because it operates as a passive reconnaissance engine, finding exposed infrastructure without requiring agents or API integrations across your estate. The free tier lets you baseline your internet-facing attack surface immediately, which matters for teams under budget pressure or those running initial scans before committing to a paid EASM tool. Skip this if your priority is vulnerability assessment and remediation workflows; ONYPHE finds what's exposed but doesn't deeply score or manage patch prioritization across discovered assets the way purpose-built EASM platforms do.
Mid-market and enterprise security teams drowning in external asset sprawl will get immediate value from Guardz External Footprint because it actually monitors your dark web exposure instead of just scanning open ports. The tool covers all four critical NIST ID and DE functions, with particular strength in continuous monitoring and asset discovery across DNS, TLS, and credential leak channels. Skip this if your organization has already mapped and locked down your external footprint; Guardz is built for teams still discovering what's actually exposed.
