Platform and supply chain: hardened or minimal base images (Chainguard, distroless, or an in-house golden image program), Kubernetes and container security at scale (we run GKE and EKS), PaaS/edge hosting such as Vercel, Netlify, or Cloudflare Pages, SBOMs and software supply chain security, and automation connecting scanner APIs to Jira, Slack, or reporting pipelines. Application and edge security: DAST and edge/WAF platforms (Invicti, Burp Suite, Cloudflare, Akamai), and vulnerability disclosure or bug bounty programs (HackerOne, Bugcrowd), including researcher communication, report validation, and duplicate handling.
