DevSecOps Professionals rely on a suite of tools to seamlessly integrate security into the development pipeline. Knowing the right tools is essential to automate processes and secure applications at every stage. In 2025, certain DevSecOps tools stand out as industry standards.
This guide groups the top DevSecOps tools 2025 by function – from CI/CD and containers to security testing and infrastructure – and explains why each is important. These are among the best security tools for developers and IT teams to master for a successful DevSecOps practice.
Version Control & CI/CD Tools
Why it matters: Version control and Continuous Integration/Continuous Deployment (CI/CD) tools form the backbone of DevOps automation. They allow teams to collaborate on code and deliver updates rapidly. For a DevSecOps specialist, mastering these tools is crucial because it’s where you will embed security checks early in the development lifecycle.
Git & GitHub: Git is the most popular version control system, and platforms like GitHub (or GitLab/Bitbucket) make collaboration easy. DevSecOps engineers use Git to manage code changes and enforce best practices (like code reviews). GitHub also offers GitHub Actions for CI, which lets you automate builds, tests, and security scans on every pull request. Mastering Git is fundamental – for example, knowing how to sign commits or use branch protection rules helps maintain code integrity.
Jenkins: Jenkins remains one of the top CI/CD tools in 2025 for automating workflows. It’s an open-source CI server that orchestrates building, testing, and deploying applications. DevSecOps teams love Jenkins for its extensibility – you can integrate security scanners into the pipeline with numerous plugins. For instance, you can configure Jenkins to include security scan steps (like a dependency vulnerability check) as part of the build pipeline. Learning Jenkins gives you a flexible platform to enforce security gates in the CI/CD process. Refonte Learning DevSecOps training projects use Jenkins to teach students how to embed security into pipelines.
GitLab CI/CD: GitLab offers an integrated solution where your repo, issue tracker, and CI pipelines are in one place. It’s gaining popularity for DevSecOps because of built-in security features – GitLab can automatically run SAST or container scans as part of the pipeline. Knowing GitLab CI/CD means you can write YAML pipeline definitions to automate everything from code commit to deployment. A practical use-case: using GitLab’s security scanning templates to check your code and containers for vulnerabilities on each merge. Mastering either Jenkins or GitLab CI (or a cloud CI service like CircleCI) is key to implementing DevSecOps automation in any environment.
Containerization & Orchestration Tools
Why it matters: Containers have revolutionized how we build and deploy software. Tools that deal with containerization and orchestration are essential for DevSecOps specialists because modern applications often run in containers. Securing the container environment – from image to runtime – is a big part of integrating security in DevOps.
Docker: Docker is the go-to tool for containerizing applications. It allows you to package apps along with their environment, ensuring consistency from development to production. For a DevSecOps practitioner, understanding Docker is non-negotiable. You’ll use it to build secure container images (for example, using minimal base images and scanning them for vulnerabilities). A typical use-case is writing a Dockerfile for your app and then using Docker to scan that image with a tool like Trivy. Mastering Docker also means knowing how to manage image repositories, handle secrets in images, and follow best practices (like not running containers as root).
Kubernetes: Kubernetes is the leading container orchestration platform, used to manage and scale containerized applications. DevSecOps specialists should be comfortable with Kubernetes (or managed services like AWS EKS or Azure AKS) because it’s often your deployment target. Key tasks include deploying applications via YAML manifests or Helm charts and ensuring security configurations are in place (such as network policies, pod security contexts, and secret management). Kubernetes has a learning curve, but it’s crucial for orchestrating containers at scale – and for enforcing security policies across your cluster. (Refonte Learning’s DevOps courses typically include hands-on labs with Docker and Kubernetes to build this competency.)
Container Security Tools: Alongside Docker and Kubernetes, you should know tools specifically designed to enhance container security. For instance, Trivy (by Aqua Security) scans container images for vulnerabilities and misconfigurations, helping ensure your images are safe to deploy. Container-focused security platforms (like Docker’s built-in scanning or Red Hat’s StackRox) can also enforce policies on your container clusters. Understanding how to integrate these tools into your CI/CD pipeline means you’ll catch insecure container configurations before they hit production.
Application Security Testing Tools
Why it matters: DevSecOps is all about baking security into development, so you need to master the tools that test your application’s security. These include static analysis tools for code, dynamic testing tools for running apps, and software composition analysis tools for dependencies. They help catch vulnerabilities continuously and early. A DevSecOps specialist should know how to wield these tools and interpret their results.
Static Application Security Testing (SAST): SAST tools analyze source code for security weaknesses without executing it. Examples include SonarQube, Checkmarx, and Snyk Code. Using SAST, you can catch issues like SQL injection risks or hardcoded secrets as developers write code. For instance, SonarQube can be integrated into a CI pipeline to fail a build if new high-risk vulnerabilities are introduced. Mastering a SAST tool means you can fine-tune security rules for your codebase and help developers fix flaws early.
Dynamic Application Security Testing (DAST): DAST tools test running applications by simulating external attacks. A top example is OWASP ZAP, an open-source tool that can crawl and attack a web app to find issues like XSS, SQL injection, and insecure configurations. Another popular option is Burp Suite (widely used for penetration testing). As a DevSecOps engineer, you might set up ZAP to run nightly against a staging environment of your web application. Learning DAST tools teaches you how to automate what a penetration tester does – and then feed those results back to developers for fixes before release.
Software Composition Analysis (SCA): SCA tools focus on your third-party components (open-source libraries, frameworks) and check for known vulnerabilities and license risks. Tools like OWASP Dependency-Check, Snyk, or Black Duck scan your project’s dependencies against vulnerability databases and alert you if you’re using a library with a known CVE. For example, Snyk can monitor your project and send a pull request to upgrade a vulnerable package. Mastering an SCA tool is crucial in the era of supply chain attacks – it ensures you’re not unknowingly shipping insecure libraries as part of your application.
Infrastructure & Configuration Tools
Why it matters: DevSecOps isn’t just about apps – it’s also about the infrastructure they run on. Infrastructure as Code (IaC) and configuration management tools let you automate environment setup, and using them securely ensures your deployments are consistent and compliant. Understanding these tools also helps you prevent misconfigurations (a common source of cloud security incidents).
Terraform: HashiCorp Terraform is the leading IaC tool for provisioning cloud infrastructure using code. Instead of clicking around a console, you write declarative configs to spin up resources (servers, databases, networks, etc.). For DevSecOps, mastering Terraform is powerful: you can enforce security at the infrastructure level (for example, ensuring all storage buckets are encrypted or no security group is overly permissive). A common scenario is using Terraform to deploy a web server and its security group, then running a scanner like Checkov on your Terraform files to catch any insecure settings (like open ports) before applying them. Knowing Terraform also means you can version-control your infrastructure and have peer reviews for changes, just like application code.
Ansible: Ansible (by Red Hat) is a popular configuration management and automation tool, great for provisioning and maintaining systems. It uses YAML playbooks to install packages, configure settings, and deploy applications. For a DevSecOps specialist, Ansible is handy for automating security hardening across multiple servers. For example, you can use Ansible to enforce configuration benchmarks (like turning off weak protocols or ensuring firewall rules) on every server consistently. It’s agentless and uses simple YAML files, making it straightforward to apply changes across many servers at once.
Secrets Management (Vault): HashiCorp Vault is a crucial tool for managing sensitive information such as API keys, passwords, and certificates. Instead of embedding secrets in code or config files, you store them in Vault and retrieve them securely when needed. DevSecOps Engineers often integrate Vault into CI/CD pipelines and applications so that credentials are provided on the fly (and even rotated regularly). Mastering Vault means you can implement dynamic secrets (e.g. generating temporary database credentials for each deployment) and ensure that sensitive data is tightly controlled throughout your infrastructure and applications.
Actionable Tips for Mastering DevSecOps Tools
Start with one per category: Don’t overwhelm yourself by trying to learn all tools at once. Focus on one representative tool in each category first (for example, Git/Jenkins for CI/CD, Docker for containers, SonarQube for code scanning, Terraform for IaC). Build a strong foundation with those, then expand to alternatives or more advanced tools.
Use hands-on labs and sandbox projects: The best way to learn these tools is by using them in a realistic setting. Create a demo project or use intentionally vulnerable applications (like OWASP’s Juice Shop) to practice running scans, deploying with containers, etc. Many tools have free community editions – set up a local lab environment and break things safely.
Automate and integrate: Treat automation as a learning tool. Write small scripts or pipeline configs to glue tools together – this not only reinforces how each tool works, but also mirrors real DevSecOps workflows. For example, automate a workflow where a Git commit triggers Jenkins, which then runs a SAST scan and builds a container image. This practice will make you proficient in using tools in concert, not just in isolation.
