Integrate the Clang Static Analyzer with Vulnetix. Use scan-build to find memory leaks, null dereferences, and security bugs in C/C++ code, then upload SARIF results.
Install & scan
$ # Ubuntu/Debian sudo apt-get install clang clang-tools # macOS via Homebrew brew install llvm # Verify scan-build is available scan-build --help $ scan-build -sarif -o sarif-results make
Run LLVM / Clang Static Analyzer in CI
Scan on every push and upload the report as a workflow artifact:
- name: Install Clang
run: sudo apt-get install -y clang clang-tools
- name: Run Clang Static Analyzer
run: scan-build -sarif -o sarif-results make
- name: Upload to Vulnetix
run: |
find sarif-results -name "*.sarif" -print0 | xargs -0 -I{} vulnetix upload --file {}
How Vulnetix compares: better together
Vulnetix does not replace LLVM / Clang Static Analyzer. Keep running it. Vulnetix sits on top of LLVM / Clang Static Analyzer (and every other scanner you already own) turning disconnected tool outputs into one prioritised, fixable queue.
| Capability | Vulnetix | LLVM / Clang Static Analyzer |
|---|---|---|
| Security coverage | ||
| SAST (static code analysis) | ✓ Built-in rules + Semgrep augmentation | ✓ Core: path-sensitive C/C++/ObjC static analysis via checkers, SARIF export selectable through scan-build |
| 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 | ✗ |
| Cloud / CSPM | ✓ Cloud-posture findings, compliance tab | ✗ |
| Mobile (MAST) | ~ Ingests mobile scanner output; no native mobile engine | ✗ |
| License compliance | ✓ SPDX, copyleft/AGPL/SSPL policy | ✗ |
| SBOM generation | ✓ CycloneDX 1.7 + SPDX 2.3, cosign-signable | ✗ |
| Malware / supply-chain | ✓ De-duplicated corpus + install-time firewall (25+ registries) | ✗ |
| Network / infra vuln | ~ Ingests network scanner output; no native network scanner | ✗ |
| Fuzzing | ✗ Ingests fuzzing crashes; no native fuzzer | ✗ |
| Pentest / bug bounty | ✗ Ingests pentest/bug-bounty findings; not a testing service | ✗ |
| The Vulnetix orchestration layer | ||
| Cross-scanner dedup & one queue (ASPM) | ✓ Correlates every scanner into one prioritised queue with ownership routing | ✗ |
| Exploit-intel prioritisation | ✓ EPSS, CISA KEV, Coalition ESS, CWSS, Vulnetix LEV | ✗ |
| Reachability analysis | ✓ Tree-sitter + CVEAffected; direct/transitive/semantic | ✗ |

What LLVM / Clang Static Analyzer does well
- Path-sensitive symbolic execution tracks per-path program state to find memory bugs (use-after-free, leaks, null deref) that pattern matchers miss, with a low false-positive design goal
- Deep, first-party understanding of C/C++/Objective-C semantics as part of the Clang/LLVM toolchain
- scan-build wraps existing builds transparently and can emit SARIF (alongside html/plist), integrating into CI without code changes
- Reusable analyzer library embedded in Xcode and many IDEs for inline developer feedback
Where Vulnetix adds to it: Vulnetix ingests the Clang analyzer's SARIF, deduplicates it against Semgrep and other SAST engines into one prioritised queue, and adds exploit-intel, reachability, versioned VEX, and SSVC that the analyzer has no notion of. Vulnetix orchestrates it, never replaces its C/C++ analysis core.
No migration, no rip-and-replace. LLVM / Clang Static Analyzer keeps doing what it does best; Vulnetix adds the orchestration, exploit-intelligence prioritisation and remediation layer built for the way AppSec works today.
Centralise LLVM / Clang Static Analyzer results in Vulnetix
Upload LLVM / Clang Static Analyzer SARIF 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.
