How to Protect Your Pipeline With DevSecOps

We’ve all seen it: a fast-moving continuous integration and continuous deployment (CI/CD) pipeline gets code out the door quickly, but with a few security oversights that only become apparent when it’s too late. A recent study of over 320,000 GitHub repos with CI/CD configurations found widespread issues, everything from exposed secrets to malicious injections, could easily slip past unnoticed.

That’s where DevSecOps comes in. It’s not about adding one more layer of process. It’s about building security into the foundation of how we write, test, and ship code. When everyone shares responsibility, you stop treating DevOps security like a final gate and start making it part of the flow.

Teams are eliminating vulnerabilities by baking automated security checks into every stage of their pipeline: static analysis on every pull request, open-source scanning on every build, and secret detection before code even hits version control.

DevSecOps gives us the blueprint to secure our code without slowing us down. That starts with visibility, automation, and the right cultural mindset.

1. Common Pipeline Weak Spots and How to Fix Them

Even the most mature pipelines have cracks because modern software delivery is complex by design. We rely on dozens of tools, plugins, and third-party services to move fast, but every component introduces potential risk. 

Open-source dependencies can come bundled with known vulnerabilities. Misconfigured access controls can give attackers a clear path to sensitive systems. Meanwhile, secrets, including API keys, credentials, and tokens, are often accidentally committed to source control in a rush to ship. 

These aren’t theoretical problems. They’re the kind of issues we see every day in real-world breaches. Here’s how to take action using DevSecOps best practices:

• Use Software Composition Analysis (SCA) to scan third-party packages for vulnerabilities every time you build. Open-source components are a magnet for attackers, and most teams use them by the hundreds. Checkmarx One’s SCA integrates directly into your CI/CD workflow to automatically identify known CVEs and license risks, giving your developers real-time feedback before a vulnerability makes it to production.
• Scan for hardcoded secrets with Checkmarx Secrets Detection to keep credentials out of source code and prevent the risk of exposure. It only takes one overlooked API key to open the door to data theft or infrastructure compromise. Our scanning tools flag secrets the moment they hit the repo, so your team can fix issues before they’re committed, or worse, pushed to a public repository.
• Set guardrails around who can access what in your build systems. Least privilege access and role-based permissions aren’t just security best practices. They’re essential for reducing your attack surface. With Checkmarx, you can enforce policy controls and automate alerts when access deviates from your security baseline.

When security is embedded directly into your workflow, you can identify risks in real time, prioritize what matters most, and reduce the noise that leads to alert fatigue. Use this visibility to track exposure trends over time, set risk thresholds for different environments, and automate escalation paths when issues exceed defined severity levels.

Integrate findings into your existing dashboards and reporting tools to give security and engineering teams a shared view of risk that drives collaborative, continuous improvement. With Checkmarx One, you see the entire picture, from code to container, so nothing slips through the cracks.

2. Building Security Into Your Pipeline From Day One

CI/CD automation has transformed how fast we deliver code, but speed without security is a recipe for risk. That’s why secure-by-design principles need to be embedded from the very first commit. When security controls are built into development workflows rather than bolted on later, you reduce friction, avoid technical debt, and catch vulnerabilities when they’re cheapest to fix. The goal isn’t to turn developers into security experts, but to empower them with the right tools, feedback, and guardrails, right where they work.

• Static Application Security Testing (SAST) with contextual risk scoring: Go beyond basic static scanning with contextual analysis based on data flow, call hierarchy, and known exploitability, so developers can focus on fixing what matters most. Integrated directly into the dev workflow, it delivers prioritized results inside integrated development environments (IDEs) and source code management (SCM) systems, turning security findings into actionable code improvements.
• Build-time threat modeling and image hardening: Instead of just scanning containers, inject security posture earlier with automated threat modeling and base image analysis. Use Checkmarx integrations to identify misconfigurations in Dockerfiles, detect use of deprecated libraries, and enforce secure defaults before an image ever runs in production.
• Automated policy enforcement: It’s essential to define and enforce guardrails across your repositories and CI/CD tools. With Checkmarx One, you can block merges or deployments if critical vulnerabilities are detected or automatically create tickets for remediation. Everything is orchestrated to align with your team’s workflow.
• Developer enablement: Beyond just flagging issues, we surface remediation guidance in plain language, offer secure code snippets, and integrate with collaboration tools like Jira and Slack so developers can act fast, without leaving their environment.

Building in security from day one isn’t just more effective; it’s simply more efficient. You reduce context switching, avoid costly rework, and foster a culture where writing secure code is just how things are done. Encourage developers to treat security findings like bugs, triaging and tracking them with the same urgency as functional defects.

For example, use CI policies to ensure every pull request runs through SAST and SCA gates. Set service level agreements (SLAs) for remediating high-risk findings and integrate those timelines directly into sprint planning. Most importantly, continuously review and refine your tooling to make sure it’s delivering actionable insights, not just noise.

3. Scaling Secure Practices With Automation and ASPM

Manual security reviews can’t keep up with the speed of modern development. Every new microservice, integration, and release multiplies the risk landscape and the burden on security teams. To keep pace, DevSecOps engineers need scalable, automated solutions that embed security directly into CI/CD pipelines and development environments without sacrificing speed or flexibility.

That’s where DevSecOps automation and Application Security Posture Management (ASPM) come in. Automation isn’t just about running scans. It’s about orchestrating the right checks at the right time with minimal developer friction. For example:

• Automate SAST and SCA scans on every pull request or build, with results delivered directly in IDEs or pull request (PR) comments so developers can resolve issues without breaking flow.
• Set up dynamic risk scoring to adjust enforcement policies based on business impact, asset sensitivity, and real exploitability. Don’t block every medium-level vulnerability—block the ones that matter most.
• Integrate with ticketing systems like Jira to auto-create issues and track SLAs for remediation.
• Use alerts strategically through Slack or Teams integrations—no more email overload.

Meanwhile, ASPM acts as the glue that holds it all together. Instead of juggling multiple tools with siloed outputs, ASPM unifies your security posture across the SDLC. With Checkmarx One, you can:

• Correlate findings across SAST, SCA, secrets detection, Infrastructure-as-Code (IaC), and container scanning
• Prioritize vulnerabilities based on runtime context and attack paths
• Track metrics like time-to-remediate and unresolved critical issues per repo or team
• Create executive dashboards that reflect real risk, not just raw scan volume

The result? A proactive, risk-aware security program that evolves with your architecture and helps your engineers move faster, with fewer surprises at release time. Take it a step further by setting automated enforcement rules that adapt as your codebase and infrastructure scale, such as tightening scan frequency on critical services or relaxing controls in non-prod environments to keep workflows smooth.

Use ASPM to continuously audit policy compliance across business units, flag drift, and uncover bottlenecks before they impact velocity. And don’t forget developer feedback loops—track which alerts are ignored, which findings are reopened, and where remediation time lags, so you can keep fine-tuning your program to match how your teams really work.

4. Getting Started and Leveling Up With DevSecOps

Whether you’re starting from scratch or optimizing an existing setup, here’s how to move forward:

• Start with a security assessment of your pipeline to identify where your blind spots and bottlenecks are
• Automate where you can, starting with the highest-value opportunities like SAST on pull requests and SCA for critical dependencies
• Adopt a maturity mindset—assess your DevSecOps posture regularly using a recognized DevSecOps maturity model and evolve your processes, tools, and policies as your architecture grows
• Build feedback loops and measure impact—track remediation velocity, false positive rates, and where developers need more enablement

And if you’re short on in-house security resources or looking to accelerate adoption, consider engaging with a trusted provider for DevSecOps as a service. Our approach lets you scale best practices with external expertise while focusing your internal teams on innovation.
