Cover SAST (SQL injection / XSS / SSRF / IDOR / RCE), SCA (OSS CVE + license + reachability), container scanning (image layer + runtime; Docker / Kubernetes), IaC scanning (Terraform / CloudFormation / Kubernetes manifests; misconfigurations), secret scanning (GitHub tokens / API keys / private key leaks), DAST (runtime test), API security (GraphQL / REST / OpenAPI schema), SBOM generation (CycloneDX / SPDX; US EO 14028 / EU CRA), license compliance (GPL / AGPL / MIT / Apache), AI code auto-fix (Snyk DeepCode AI / GHAS Copilot Autofix / Semgrep Assistant - +60% PR acceptance), reachability analysis (Endor Labs - noise -85%), ASPM (Apiiro / Cycode - tool consolidation + risk-based), code-to-cloud (Wiz Code - pre-prod + runtime visibility), Shift-Left (IDE plug-in + pre-commit + PR block - 5-min feedback loop), multi-tool defense (2 SAST + 2 SCA + 1 CNAPP), container runtime security (Falco / Aqua Trivy Operator), and AI-generated code security (Copilot / Cursor output SAST). Deliver +90% vulnerability detection, -80% false positives (60% to 12%), -70% fix time (60 to 18 days), 100% SBOM coverage, +60% AI auto-fix acceptance, 24h Critical CVE remediation, $5M+ saved annual breach cost, SOC 2 / PCI DSS v4.0 / EU CRA / US EO 14028 compliance, and tap a market projected at $45B by 2030 (25% CAGR). Selection guide: (A) indie / solo dev = Aikido Free or Semgrep CE + Snyk Free + GitHub Dependabot = free; (B) startup (1-10 devs) = Snyk Team + GHAS + Semgrep Pro = $500/mo; (C) mid-stage (10-50 devs) = Snyk + GHAS + Endor Labs + Wiz Code = $50K/yr; (D) growth (50-200 devs) = Snyk Enterprise + GHAS + Apiiro / Cycode ASPM + Wiz Code = $200K/yr; (E) enterprise (200-2,000 devs, F500) = Checkmarx One or Veracode + Snyk Enterprise + Wiz Code + Apiiro = $500K-3M/yr; (F) highly regulated (finance / healthcare / defense) = Checkmarx One + Veracode + SonarQube Enterprise + JFrog Xray + Black Duck = $1M-5M/yr (FedRAMP / HIPAA / PCI DSS v4.0); (G) cloud-native (K8s + microservices) = Snyk + Wiz Code + Aqua / Sysdig + Trivy = $300K/yr; (H) Java + Maven = Snyk + Mend.io + SonarQube + Veracode = $200K/yr; (I) Node.js + npm = Snyk + Semgrep + GHAS = $50K/yr; (J) Python = Snyk + Semgrep + Dependabot = $30K/yr; (K) OSS / self-host = Semgrep CE + Trivy + Grype + Dependency-Track + OWASP ZAP = $10K/yr (infra); (L) Japan = Snyk Japan + GitLab Ultimate + SonarQube + Yamory (JP SCA) = 10M-100M JPY/yr. Five success factors: AI code auto-fix (+60% acceptance), reachability analysis (noise -85%), ASPM (risk-based prioritization), Shift-Left (IDE + PR block), mandated SBOM (US EO 14028 / EU CRA). 2026 trends: AI code auto-fix +60%, reachability analysis noise -85%, ASPM, code-to-cloud (Wiz Code), mandated SBOM, supply chain security (Log4Shell defense), AI-generated code security, Shift-Left (5-min feedback), multi-tool defense, container runtime security. Roadmap: Week 1 vendor demos + repo inventory + OSS dependency baseline + SBOM; Month 1 Snyk + GHAS + top-10 repos SAST + SCA + secret scan + IDE plug-in (critical CVE visible); Months 2-3 full repo rollout + IaC + container scan + PR block + AI auto-fix (-50% FP, -30% fix time); Month 6 ASPM (Apiiro / Cycode) + Wiz Code + reachability (-80% noise, -60% fix time); Year 1 full ops (+90% detection, -80% FP, -70% fix time, 100% SBOM, +60% auto-fix adoption, 24h Critical CVE, $5M+ saved).
