censys-subdomain-finder vs Halo Security Attack Surface Discovery: 2026 Comparison

Halo Security Attack Surface Discovery

Mid-market and enterprise security teams drowning in shadow infrastructure will find real value in Halo Security Attack Surface Discovery because it actually finds what you don't know you're running, then keeps finding it as things change. The agentless external scanning and automated rescans mean you're catching newly exposed assets and misconfigured domains without adding operational overhead, which directly strengthens your ID.AM and ID.RA posture under NIST CSF 2.0. Skip this if you need internal vulnerability scanning or remediation workflows; Halo stops at discovery and inventory, leaving the actual patching to you.
