A DevSecOps engineer is responsible for making sure security is built into every stage of the software development process, not just tacked on at the end. They bridge the gap between development, security, and operations teams to identify, prevent, and fix security issues as code is written, tested, and deployed.
This means they work alongside developers and IT operators right from day one, embedding cybersecurity practices and tools directly into workflows. Instead of waiting until after software is released, a DevSecOps engineer ensures every feature and update gets checked for security risks from the ground up. Their goal? Safer, faster releases without bottlenecks, and resilience against cyberattacks.
DevSecOps stands for Development, Security, and Operations. A DevSecOps engineer is the pro tasked with making security a team sport in the world of building and running software. Gone are the days when security only showed up in the last five minutes before launch. The DevSecOps engineer brings security into every step, working side-by-side with developers and IT to make sure nothing slips through the cracks.
These experts use a blend of automation, collaboration, and hands-on know-how to catch vulnerabilities early, implement security controls, and respond rapidly to threats as they crop up. By integrating security checks, testing, and policies throughout each stage, they help teams move faster while making software safer.
Cybercriminals don’t wait for a project to be finished before trying to sneak in. Every time code is pushed live or new features roll out, there’s a potential for new vulnerabilities. The old-school, “security last” method puts organizations at risk, especially as release cycles speed up.
DevSecOps is a modern, proactive answer. It embeds security directly into CI/CD (continuous integration and continuous deployment) practices, shrinking the time between code being written and security issues being found. This not only helps prevent incidents but can also reduce the cost and headaches of fixing problems after the fact.
Here’s what the role looks like broken down:
Embed security into DevOps pipelines
DevSecOps engineers build and maintain tools that automatically scan code, infrastructure, and applications for security flaws at every stage.
Automate security tests and checks
They set up automated tests that check for vulnerabilities, misconfigurations, and compliance issues before code is deployed.
Collaborate across teams
These pros don’t work in a silo. They coach developers on secure coding practices, help IT teams safeguard cloud resources, and act as a go-to resource for all things security.
Monitor for threats and respond quickly
Using monitoring and alerting tools, DevSecOps engineers keep an eye on production environments to spot (and squash) potential intrusions, misconfigurations, or suspicious activity fast.
Promote a culture of shared security responsibility
They educate, advocate, and sometimes even gamify security awareness among all teams to make it a habit, not a hurdle.
Integrate security scanning into CI/CD workflows (using tools like Snyk, SonarQube, or open-source equivalents)
Remediate vulnerabilities as soon as they’re discovered
Define security policies and ensure they’re automatically applied
Review code and infrastructure changes from a risk perspective
Prepare for and participate in security audits
Keep up with current threats, compliance requirements, and best practices
Security automation tools (for example, static and dynamic analysis, container scanning)
Cloud security know-how (AWS, Azure, GCP security practices)
Coding/scripting skills (Python, Bash, Groovy, and others)
Familiarity with infrastructure as code (IaC)
CI/CD pipeline experience
Soft skills (communication, collaboration, problem-solving)
Picture a startup building a web app. The DevSecOps engineer ensures:
The code gets scanned for vulnerabilities automatically with every commit
Secrets and keys aren’t accidentally published
Cloud resources have least-privilege access policies
When a new threat crops up (say, a new exploit in a popular library), the pipeline blocks deployment until the issue is fixed
This continuous, integrated process helps prevent incidents before they reach customers.
Not sure how to get started? Here’s a roadmap:
Learn programming (Python is a common go-to)
Get a handle on cloud platforms (start with AWS or Azure)
Dive deep into cybersecurity basics
Explore automation and CI/CD tools (Jenkins, GitLab CI, etc.)
Practice with open-source DevSecOps tools
Consider relevant certifications like CompTIA Security+, AWS Security Specialty, or Certified DevSecOps Professional
Role Element | Description |
Security in CI/CD | Automates checks for vulnerabilities during builds, tests, and deployments |
Collaboration | Works with developers, security, and ops for integrated best practices |
Threat Monitoring | Watches production systems for suspicious activity |
Policy Enforcement | Ensures compliance and security rules are always active |
DevSecOps engineers act as the glue between security and speed in software projects
They empower teams to detect, prevent, and fix security issues early
Automation and collaboration underpin their daily work
The approach is highly relevant in a threat landscape that’s always changing
Up-to-date skills in CI/CD, automation, code, and cloud are essential
