Cloud & DevOps
DevSecOps is an extension of DevOps that integrates security practices, tools, and accountability into every phase of the software development and deployment lifecycle — making security a shared responsibility rather than a final-stage gate.
Traditional security models performed security reviews and penetration tests only at the end of the development cycle, after the cost of fixing vulnerabilities was highest. DevSecOps shifts security left — embedding automated security checks early in the CI/CD pipeline — including static application security testing (SAST) to scan source code for vulnerabilities, software composition analysis (SCA) to detect known CVEs in open-source dependencies, and dynamic application security testing (DAST) against running applications. Infrastructure as code (IaC) is scanned for misconfigurations (open S3 buckets, overly permissive IAM roles) before provisioning, and container images are scanned for vulnerabilities before deployment. Security champions embedded in development teams and regular threat modelling sessions ensure that security requirements are considered during design, not retrofitted after the fact.
Example
A healthcare SaaS company adds Snyk to its GitHub Actions CI pipeline to automatically block pull request merges when a dependency has a CVSS score above 7.0, catching a critical vulnerability in a JSON parsing library before it reaches production.
Related terms
DevOps
DevOps is a set of practices, cultural principles, and tooling that unifies software development (Dev) and IT operations (Ops) to shorten delivery cycles, improve deployment frequency, and increase system reliability.
CI/CD (Continuous Integration / Continuous Delivery)
CI/CD is a DevOps practice in which code changes are automatically built, tested, and deployed through a pipeline, enabling teams to deliver software updates rapidly and reliably.
Containerization
Containerization is a lightweight virtualisation technique that packages an application and all its dependencies — libraries, configuration, and runtime — into a portable, isolated container that runs consistently across any environment.
Version Control
Version control is a system that records every change made to source code over time, enabling teams to track history, revert to previous states, and collaborate on the same codebase simultaneously without overwriting each other's work.
