DevSecOps, which is short for development, security, and operations, is the practice of integrating security directly into every phase of the software development lifecycle (SDLC), from planning and coding to building, testing, releasing, and operating applications.

DevSecOps vs DevOps
DevOps focuses on streamlining how software is built, tested, and released so teams can ship quickly and reliably by using automation and close collaboration between development and operations teams. DevSecOps keeps those goals but also integrates security throughout every phase of the development lifecycle, treating it as everyone’s responsibility rather than a final gate or a separate team’s problem.

DevSecOps Best Practices
Shift Left
“Shift left” means introducing security practices at earlier stages of the development process rather than waiting until near the end or after deployment. By shifting security left, it allows teams to identify security threats early and provide developers with immediate and actionable feedback while the code is still fresh and cheap to change.
Security as Code
“Security as Code” means encoding security policies, controls, and checks the same way you treat application code that is versioned, reviewed, tested, and automated in CI/CD. Treating policies as code improves developer workflows by turning security into automated feedback instead of a manual review. The result is security that scales with delivery, is tested like code and enforced automatically with each update.
Continuous Monitoring
Continuous Monitoring tools provide real-time observation and analysis of applications and infrastructure security from planning to production environments to identify potential security risks. Automated vulnerability scanners, policy as code, and telemetry pipelines continuously collect and evaluate signals across code, builds, cloud configs, and runtime. This proactive approach provides real-time threat detection and ensures that security is improving with every release.
Automation
Replace manual gates with automated guardrails. Run code scans on every commit, check dependencies on every build, validate containers and infrastructure as code on every pull request, and enforce policies at deployment time. Use automation for common fixes and escalate the rest through pull requests or tickets.
Culture of Shared Responsibility
A culture of shared responsibility in DevSecOps means developers, security, and operations own security outcomes together from planning to production. Security champions inside product teams translate policies into practical guidance, help triage noise, and feed rule improvements back to central teams. Blameless post-incident reviews and transparent metrics keep accountability healthy and measurable. With clear ownership and adaptable workflows, teams continuously improve tests, policies, and runbooks, turning security into a collaborative habit rather than a late-stage gate.
Traceability, Auditability, Visibility
By implementing traceability, auditability, visibility in a DevSecOps process delivers clearer insight and strengthens overall security.
Traceability
Link every change from requirement to runtime: ticket → PR/commit → build → artifact → deploy. Include who did it, what changed, when, and why. This makes root-cause analysis fast, clarifies ownership, and prevents “mystery changes.”
Auditability
Produce verifiable, reviewable evidence for controls and changes: immutable CI/CD logs, approvals, signed artifacts, SBOMs, and documented exceptions with expiry. This turns audits into verification of facts instead of manual scavenger hunts.
Visibility
Provide real-time insight into code, pipelines, cloud configs, and runtime risk through unified dashboards, alerts, and ownership. With clear signals and thresholds, teams spot drift and threats early and act quickly to reduce impact.
DevSecOps Tools
DevSecOps relies on a diverse set of tools that integrate security checks across every stage of the development and deployment pipeline. Some of the most commonly used tools include:
Static Application Security Testing (SAST)
SAST tools analyze source code and configurations to find insecure patterns such as SQL injection, weak cryptography, and dangerous APIs before the application runs. In a DevSecOps toolchain, SAST solutions run in IDEs and CI on every pull request, provide line-level findings with guidance, and block merges on high-severity issues. It is ideal for early detection and for enforcing secure coding guidelines.
Interactive Application Security Testing (IAST)
IAST tools instrument a running application in a test or staging environment to examine the code behavior during execution. By associating each request with the lines that run, IAST detects exploitable vulnerabilities with higher fidelity and fewer false positives than SAST or DAST, as well as pointing to the exact code that was executed, and providing simple steps to reproduce the issue.
Dynamic Application Security Testing (DAST)
DAST tools perform automated black box testing against a deployed application in a staging or test environment. They simulate attacker traffic and exercise real user flows with test accounts. Using your OpenAPI spec as a map, these tools explore endpoints and try abusive inputs to reveal weak authentication, unsafe redirects, configuration drift, and injection. These findings are then logged in CI/CD and assigned to the right teams for follow-up.
Software Composition Analysis (SCA)
Software Composition Analysis (SCA) is an automated process to find open-source packages in an application. SCA solutions identify all third-party libraries and dependencies in the codebase, match them to known CVEs, and evaluate license compliance in real time. When integrated into CI/CD pipelines, SCA can block builds with critical vulnerabilities and alert developers to fix the issue.
Secret Scanning and Container Security
Secret scanning is an automated process to detect hardcoded API keys, tokens, and passwords in code, commit history, and configuration. Enforce pre-commit hooks and rotate any exposed credentials.
Container security scans base images and layers for CVEs, enforces minimal images, and validates runtime configurations such as no root user, read-only file systems, and dropped capabilities. Integrate with your registry so vulnerable images are quarantined automatically.
Benefits of DevSecOps
Faster Delivery
DevSecOps practices save time by building automated security checks and guardrails directly into the CI/CD pipeline, helping to identify issues throughout the SDLC and preventing late-stage vulnerability fixes.
Proactive Security
DevSecOps makes security proactive by turning it into an always-on, automated feedback loop that runs from design to production, to ensure that risks are predicted, prevented, and proven safe before they become incidents.
Reduced Costs
Using strong DevSecOps practices reduces costs because you prevent expensive problems instead of cleaning them up later. Finding a vulnerability in code review or CI costs minutes, but finding the same issue in staging or production can result in hours of rework, hotfixes, and even downtime.
Greater Collaboration and Culture Shift
The DevSecOps approach is a key to unlock greater collaboration between Dev, Sec, and Ops because it makes security a shared ownership and as it becomes a visible part of the development pipeline rather than a late-stage checkpoint.
Continuous Compliance
Regulations such as PCI DSS, HIPAA, ISO 27001, SOC 2, and cloud provider baselines require proof. DevSecOps automates compliance by embedding checks and evidence collection into CI and CD. Policy as code enforces standards on every change. At the same time, pipelines generate versioned artifacts like SBOMs, test results, signatures, and approvals, and dashboards expose compliance posture in near real time. The result is predictable, audit-ready releases that reduce risk and overhead.
