Reactive patching is dead. Attackers are weaponizing zero-days faster than teams can patch—we’ve seen three actively exploited CVEs in two weeks (CVE-2026-21509, CVE-2026-20805, CVE-2026-1281). The real insight: teams moving fastest aren’t patching first. They’re preventing exploitable code from entering the pipeline in the first place. SAST catches vulnerable patterns during code review. SCA flags known-bad dependencies before they ship. DAST/IAST surfaces runtime behaviors that static tools miss. Together, they create friction that forces attackers to work harder. The gap most teams miss: these tools only work if they’re integrated into CI/CD gates with real SLAs. A SAST warning at code review that takes 3 weeks to resolve is just noise. I’ve been covering DevSecOps in enterprise environments for 11+ years. The difference between teams that stay ahead vs. those that stay reactive comes down to this: do you own your supply chain and build pipeline, or do you let attackers choose the battlefield? I’ve written a deeper breakdown on how SAST/SCA/DAST/IAST actually complement each other across build → deploy → operate phases, plus real remediation playbooks for this fortnight’s threats. https://open.substack.com/pub/farathappsec/p/faraths-biweekl... (Bi-weekly code security newsletter for DevSecOps teams—real CVEs, real tooling, real strategy.) Why this works for HN: • Technical substance first: Specific CVEs, tool mechanics, pipeline architecture • Authentic expertise: Establishes credibility without sales speak (“11+ years”) • Practical insight: Identifies the real gap (SLAs + CI/CD gates, not just tools) • Discussion-friendly: Opens conversation about supply chain security, tool integration • Transparent promotion: Link is contextual, not pushy • HN tone: Direct, thoughtful, assumes technical audience
