What is DevSecOps in simple terms?

DevSecOps is a software delivery approach that integrates security into every stage of development. Instead of checking for vulnerabilities only before launch, teams include security practices during planning, coding, testing, deployment, and production monitoring.

What does DevSecOps stand for?

DevSecOps stands for development, security, and operations. It describes a collaborative approach where developers, security teams, and operations teams share responsibility for building, releasing, and maintaining secure software.

How is DevSecOps different from DevOps?

DevSecOps extends DevOps by embedding security controls into the software delivery lifecycle. DevOps focuses on faster and more reliable delivery, while DevSecOps adds security testing, automated guardrails, risk-based approvals, and continuous monitoring.

What are the main stages of the DevSecOps lifecycle?

The main stages of the DevSecOps lifecycle are planning, coding, building, testing, releasing, deploying, operating, and continuous improvement. Each stage includes relevant security checks, such as threat modelling, secrets scanning, dependency scanning, infrastructure validation, and runtime monitoring.

What security checks are commonly used in a DevSecOps pipeline?

Common DevSecOps security checks include static application security testing, software composition analysis, secrets scanning, dynamic application security testing, infrastructure-as-code scanning, container-image scanning, and runtime monitoring.

Who is responsible for security in DevSecOps?

Security is a shared responsibility in DevSecOps. Developers write secure code and fix vulnerabilities, security teams define controls and prioritize risks, DevOps teams integrate checks into pipelines, and operations teams monitor production systems.

Does DevSecOps slow down software releases?

A poorly designed security process can slow down releases, but effective DevSecOps aims to reduce delays. Automated and risk-based controls help teams identify serious issues earlier while avoiding unnecessary manual approvals.

Is DevSecOps only for large companies?

No. Startups and smaller teams can adopt DevSecOps gradually. They can begin with lightweight controls such as secrets scanning, dependency checks, infrastructure validation, and clearly defined remediation ownership.

Does DevSecOps include monitoring after deployment?

Yes. DevSecOps includes production monitoring, vulnerability management, configuration reviews, and continuous feedback loops. Security remains important after release because new vulnerabilities and infrastructure risks can emerge over time.
