HailBytes ASM vs Qualys CSAM
A self-hosted EASM alternative for teams that want active external recon ownership without committing to the Qualys Cloud Platform.
TL;DR
Qualys CyberSecurity Asset Management (CSAM) with the EASM add-on layers external discovery onto Qualys’s mature internal asset and vulnerability management platform. HailBytes ASM is a self-hosted alternative that runs the recon pipeline inside your own AWS or Azure account, priced on infrastructure rather than per-asset Qualys subscription.
- Pick HailBytes ASM if you don’t want a Qualys Cloud Platform commitment, need white-label client deliverables, or want unlimited scans at flat VM cost.
- Stay with Qualys CSAM if you’re already standardized on Qualys VMDR and want EASM correlated with internal asset and vulnerability data inside the same console.

When HailBytes ASM Wins
- You don’t want a Qualys Cloud Platform commitment. CSAM’s value is unifying internal and external assets inside Qualys; standalone external discovery doesn’t justify the platform tax.
- MSSPs and pen-test firms. White-label deliverables and per-instance cost make resold continuous monitoring viable.
- Government and regulated industries. AWS GovCloud and Azure Government deployments, with data never leaving your tenancy.
- AI-agent recon workflows. The built-in MCP server lets Claude, Cursor, and Windsurf drive scans and triage findings.
When Qualys CSAM Wins
- Heavy Qualys VMDR shops. CSAM’s unified view of internal and external assets is a genuine differentiator inside the Qualys ecosystem.
- Vulnerability-management depth is the priority. The VMDR engine has years of detection coverage that pure recon-tooling won’t match.
- Existing Qualys contract spend that absorbs the EASM add-on at marginal cost.
