Integrate Honggfuzz with Vulnetix. Fuzz C/C++ targets using software or hardware coverage, then convert crash findings to JSON for upload.

How Vulnetix compares: better together
Vulnetix does not replace Honggfuzz. Keep running it. Vulnetix sits on top of Honggfuzz (and every other scanner you already own) turning disconnected tool outputs into one prioritised, fixable queue.
| Capability | Vulnetix | Honggfuzz |
|---|---|---|
| Security coverage | ||
| SAST (static code analysis) | ✓ Built-in rules + Semgrep augmentation | ✗ |
| SCA / dependencies | ✓ 40+ ecosystems, transitive graph | ✗ |
| DAST (dynamic testing) | ~ Ingests DAST results; no native dynamic engine | ✗ |
| Container & image | ✓ Image CVEs, base image, Dockerfile | ✗ |
| IaC / misconfiguration | ✓ Terraform, k8s, CloudFormation | ✗ |
| Secret scanning | ✓ 1,000+ rules, source + binary + git history | ✗ |

| Network / infra vuln | ~ Ingests network scanner output; no native network scanner | ✗ |
| Fuzzing | ✗ Ingests fuzzing crashes; no native fuzzer | ✓ Feedback-driven, hardware-coverage-capable C/C++ fuzzer; its sole purpose. |

What Honggfuzz does well
- Security-oriented feedback-driven fuzzer battle-tested internally at Google on Chrome, Android and other critical targets
- Hardware-assisted coverage via Intel BTS and Intel PT in addition to software SanitizerCoverage, enabling feedback even on hard-to-instrument targets
- Multi-threaded by default, running N parallel fuzzing instances, with persistent-mode iteration speeds up to ~1M/sec
- Works with ASAN/MSAN/UBSAN and provides compiler wrappers for straightforward C/C++ harnessing
Where Vulnetix adds to it: Vulnetix has no native fuzzing engine and does not run Honggfuzz; it ingests and orchestrates Honggfuzz crash output, consolidating it with scanner findings into one deduplicated, prioritised queue with exploit-intel, reachability, versioned VEX and Safe Harbour autofix. Better together: Honggfuzz surfaces the crashes, Vulnetix prioritises and drives them to fix.
No migration, no rip-and-replace. Honggfuzz keeps doing what it does best; Vulnetix adds the orchestration, exploit-intelligence prioritisation and remediation layer built for the way AppSec works today.
Centralise Honggfuzz results in Vulnetix
Upload Honggfuzz JSON output to the Vulnetix platform to deduplicate findings, prioritise them with EPSS, CISA KEV and Coalition ESS exploit intelligence, and track remediation across every scanner in a single queue.
