HailBytes ASM vs Palo Alto Cortex Xpanse
A self-hosted EASM alternative for teams that want continuous external recon without a Cortex XSIAM commitment, or that need scan ownership and white-label deliverables.
TL;DR
Cortex Xpanse (the rebranded Expanse acquisition) is enterprise EASM tightly integrated with Cortex XSIAM and the broader Palo Alto Networks platform. List prices are firmly enterprise-tier. HailBytes ASM is a self-hosted alternative that runs the recon pipeline inside your own AWS or Azure account, priced on infrastructure rather than as a Cortex module.
- Pick HailBytes ASM if you don’t want a Cortex platform commitment, need white-label deliverables, want unlimited scans at a flat VM cost, or need full data residency.
- Stay with Cortex Xpanse if you’re already a heavy Palo Alto / XSIAM customer and want EASM data correlated with XDR telemetry inside the same platform.

| Government cloud (GovCloud / Azure Gov) | ✅ Both | 🟡 Limited |
| White-label for client deliverables | ✅ Built-in | ❌ |
When HailBytes ASM Wins
- You don’t want a Cortex/XSIAM commitment. Xpanse’s value compounds inside the PAN platform; standalone is hard to justify against a self-hosted alternative.
- MSSPs and pen-test firms. A flat per-instance cost and white-label output are what make resold continuous monitoring profitable to package.
- Government and regulated industries. AWS GovCloud and Azure Government deployments keep scan data inside the tenancy you already control.
- AI-agent recon workflows. A built-in MCP server lets Claude, Cursor, and Windsurf drive scans and finding triage from the IDE.
When Cortex Xpanse Wins
- Heavy PAN / XSIAM customers. Native correlation and the ASR auto-remediation playbooks are real differentiators.
- Fortune-500 scale orgs with the procurement appetite for PAN’s pricing tier.
- Existing PAN contract spend that absorbs the Xpanse SKU at marginal cost.
