HailBytes ASM vs Mandiant ASM
A self-hosted EASM alternative for teams that want continuous external recon without committing to the Mandiant Advantage / Google Cloud Security stack.
TL;DR
Mandiant Attack Surface Management (the rebranded Intrigue acquisition, now sold under Google Cloud Security) layers external discovery onto Mandiant’s threat-intel and incident-response heritage. 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 Mandiant Advantage module.
- Pick HailBytes ASM if you don’t want a Mandiant Advantage / Google Cloud commitment, need white-label client deliverables, or want unlimited scans at flat VM cost.
- Stay with Mandiant ASM if you’re standardized on Mandiant Threat Intelligence / Chronicle and want EASM correlated with adversary-tracking data inside the same platform.
Pricing & Cost Model
| Dimension | HailBytes ASM | Mandiant ASM |
|---|---|---|
| Pricing axis | Infrastructure ($0.24/vCPU/hour) | Per asset / Mandiant Advantage subscription tier |
| Annual cost (small surface) | $11,760 (8 vCPU; $16,800 list) | ~$25,000+ (Advantage floor) |
| Annual cost (mid surface) | $11,760–$23,520 (8–16 vCPU; $16,800–$33,600 list) | $60,000–$150,000 |
| Standalone purchase | ✅ | 🟡 Often bundled with Mandiant TI |
| Free trial | 30 days via AWS / Azure Marketplace | Sales-led demo |
| Procurement path | Cloud marketplace (counts toward EDP / MACC) | Direct Google Cloud / Mandiant contract |
HailBytes figures are the 1-year commitment price — delivered as an AWS or Azure private offer, not a discount on the published meter — with list alongside, so the comparison sits on the same annual-contract basis as the competitor column. 8 vCPU ($16,800 list) is the entry size. The meter covers software only; the VM, storage, and networking run in your own cloud account and are billed separately at roughly $35/vCPU/month — $280/month at 8 vCPU, $560 at 16, $1,120 at 32 — so scale that line to the size on the row you are reading, not to 8 vCPU. All-in at 8 vCPU that is about $20,160/year at list or $15,120 on a 1-year commitment, and every break-even quoted on this page is calculated on that all-in basis. Full pricing.
Sizing above 8 vCPU: ASM sizes its scan worker from the host, so a larger instance scans proportionally faster — a 16 vCPU deployment gives the scan engine twice the cores an 8 vCPU one does. Instances deployed before August 2026 pick this up on the next update, when the installer rewrites the worker limits to match the machine.
Architecture & Control

Capability Comparison
| Capability | HailBytes ASM | Mandiant ASM |
|---|---|---|
| Subdomain enumeration | ✅ Multi-source | ✅ (Intrigue heritage) |
| Active port & service scanning | ✅ Built-in | ✅ |
| CVE matching | ✅ | ✅ |
| Adversary infrastructure / threat-intel pivots | ❌ | ✅ Mandiant TI is the moat |
| Chronicle / SecOps correlation | 🟡 Bring your own SIEM | ✅ Native |
| Unlimited scans | ✅ | 🟡 Tier-based |
| Custom wordlists | ✅ Unlimited | ❌ |
| AI-powered analysis | ✅ OpenAI + Ollama (local GPU) | ✅ Gemini-powered |
| MCP server / AI-agent tooling | ✅ Built-in (Claude / Cursor / Windsurf) | ❌ |
| SIEM integration | ✅ Splunk, Sentinel, Elastic, Chronicle | ✅ Chronicle-first |
| Government cloud (GovCloud / Azure Gov) | ✅ Both | 🟡 Google Cloud Gov |
| White-label for client deliverables | ✅ Built-in | ❌ |
When HailBytes ASM Wins
- You don’t want a Mandiant Advantage / Google Cloud commitment. Mandiant ASM’s real value is correlation with Mandiant TI and Chronicle; standalone, the math is hard.
- MSSPs and pen-test firms. White-label deliverables and per-instance cost make resold continuous monitoring viable.
- AWS-first or multi-cloud orgs. Mandiant ASM lives inside Google Cloud; HailBytes runs anywhere.
- AI-agent recon workflows. The built-in MCP server lets Claude, Cursor, and Windsurf drive scans and triage findings.
When Mandiant ASM Wins
- You’re a Mandiant TI customer. Adversary-infrastructure pivots from Mandiant’s frontline-incident corpus is a real differentiator pure recon-tooling can’t match.
- Chronicle / Google SecOps shops. Native correlation across ASM and SIEM data is a meaningful win.
- Existing Google Cloud / Mandiant contract spend that absorbs the ASM module at marginal cost.
