Halo Security Attack Surface Discovery vs Zerocopter Recon: Side-by-Side Comparison (2026)

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.

Zerocopter Recon

Mid-market and enterprise security teams drowning in shadow IT will find real value in Zerocopter Recon's human-led reconnaissance model, which catches forgotten assets and misconfigurations that automated scanners routinely miss. The vendor's 31-person structure and Netherlands-based operations mean slower response cycles than US-based competitors, but the expert-led approach maps both NIST ID.AM and ID.RA functions in one pass, eliminating the typical workflow tax of stitching together separate asset discovery and risk assessment tools. Skip this if your organization has already achieved 95% asset visibility or runs a mature continuous scanning program; Zerocopter is built for the messy middle, not for hardening what you already know.
