Integrate RuboCop with Vulnetix. Lint Ruby code for style violations, security issues, and performance anti-patterns, then upload JSON results.
Install & scan
$ gem install rubocop # Or add to Gemfile bundle add rubocop --dev $ rubocop --format json --out rubocop.json
Run RuboCop in CI
Scan on every push and upload the report as a workflow artifact:
- name: Run RuboCop
run: |
gem install rubocop
rubocop --format json --out rubocop.json
- name: Upload to Vulnetix
run: vulnetix upload --file rubocop.json
How Vulnetix compares: better together
Vulnetix does not replace RuboCop. Keep running it. Vulnetix sits on top of RuboCop (and every other scanner you already own) turning disconnected tool outputs into one prioritised, fixable queue.
| Capability | Vulnetix | RuboCop |
|---|---|---|
| Security coverage | ||
| SAST (static code analysis) | ✓ Built-in rules + Semgrep augmentation | ~ Lint + Security department cops catch unsafe Ruby patterns; primarily a style/quality analyzer, not a full SAST engine |
| 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 RuboCop does well
- Standard Ruby static analyzer and autocorrecting formatter, organised into departments (Layout, Lint, Metrics, Naming, Style, Security)
- Lint department detects real logic errors (unused variables, dead code, suspicious constructs) beyond formatting
- Dedicated Security cops (Security/Eval, Security/Open, Security/YAMLLoad, Security/JSONLoad) flag unsafe Ruby idioms tied to RCE and injection
- Rich extension ecosystem (rubocop-rails, rubocop-rspec, rubocop-performance) and JSON output for CI pipelines
Where Vulnetix adds to it: Vulnetix ingests RuboCop findings into its cross-scanner queue, dedups Ruby code issues against dependency and secret findings, and applies EPSS/KEV exploit-intel prioritisation, reachability, versioned VEX and SSVC policy that RuboCop does not model. Vulnetix's native SAST plus Semgrep adds security-rule depth while RuboCop remains the language-native Ruby linter/formatter it never replaces.
No migration, no rip-and-replace. RuboCop keeps doing what it does best; Vulnetix adds the orchestration, exploit-intelligence prioritisation and remediation layer built for the way AppSec works today.
Centralise RuboCop results in Vulnetix
Upload RuboCop 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.
