HailBytes ASM vs CrowdStrike Falcon Surface
A self-hosted EASM alternative for teams that want continuous external recon without committing to the CrowdStrike Falcon platform, or that need scan ownership and white-label deliverables.
TL;DR
CrowdStrike Falcon Surface (the rebranded Reposify acquisition) bundles EASM into the broader Falcon platform. That’s convenient if you’re already standardized on Falcon, and expensive if you aren’t. HailBytes ASM is a self-hosted alternative that runs the recon pipeline inside your own AWS or Azure account, priced as infrastructure rather than as a Falcon module.
- Pick HailBytes ASM if you don’t want a Falcon platform commitment, need white-label client deliverables, want unlimited scans at a flat VM cost, or need full data residency.
- Stay with Falcon Surface if you’re already a heavy Falcon customer and want EASM correlated with EDR telemetry inside the same console.

| Government cloud (GovCloud / Azure Gov) | ✅ Both | 🟡 GovCloud-1 only |
| White-label for client deliverables | ✅ Built-in | ❌ |
When HailBytes ASM Wins
- You don’t want a Falcon platform commitment. Falcon Surface earns its keep via correlation with Falcon EDR; pulled out of that context, the standalone module is hard to justify on cost alone.
- MSSPs and pen-test firms. White-label output plus a fixed per-instance cost is what turns resold continuous monitoring into a real margin line. Pen-test firm playbook.
- Government and regulated industries. Run in AWS GovCloud or Azure Government and your scan data stays inside the tenancy you control.
- AI-agent recon workflows. A built-in MCP server hands Claude, Cursor, and Windsurf direct control over scans and finding triage.
When Falcon Surface Wins
- Heavy Falcon customers. The EDR + EASM correlation in one console is the real product moat.
- Charlotte AI users. If you already pay for Charlotte, the AI-driven triage extends naturally to Surface findings.
- Existing CrowdStrike contract spend that absorbs the Surface SKU at marginal cost.
