DevSecOps consultants and application security engineers

Application security engineers review planned features and existing code to identify exploitable design decisions before changes reach production. Bring one in when authentication changes or sensitive data flows need scrutiny.

• Threat modelling: Map trust boundaries and abuse cases, then turn risks into engineering tasks using STRIDE where appropriate.
• Architecture and code review: Examine authorization and API access controls against relevant OWASP ASVS requirements. Document findings with reproduction steps and specific remediation guidance.

DevSecOps consultants integrate security checks into GitHub Actions or GitLab CI without making every scanner warning a release blocker. They configure static analysis with CodeQL or Semgrep and agree failure thresholds with engineering teams.

Software supply chain work covers dependency scanning and container image checks, with tools such as Trivy. Specialists can also introduce secret detection and software bills of materials (SBOMs). Each check needs an owner and an exception process so unresolved findings remain visible after a release.

AppSec engineers investigate weaknesses in web applications and APIs, then support developers with code-level corrections. Testing combines manual verification with tools such as Burp Suite or OWASP ZAP; automated scan output requires validation before it becomes a remediation task.

• Web and API testing: Assess authorization bypasses and injection risks using reproducible test cases within an agreed scope.
• Secure coding support: Review proposed patches and add regression tests for confirmed vulnerabilities. Retest the affected behavior before closing findings.

An AppSec engineer can take ongoing responsibility for vulnerability triage when findings accumulate faster than developers can investigate them. Prioritization considers exploitability and business impact rather than severity scores alone.

Support includes checking whether affected dependencies are reachable in production and coordinating remediation with application owners. Specialists maintain exception records with expiry dates and track fixes through retesting. For newly disclosed vulnerabilities, they identify affected applications and verify whether temporary mitigations address the exposure while a permanent correction is prepared.
