Assetnote Attack Surface Management Tool vs ONYPHE: 2026 Comparison

ONYPHE

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.
