What is DevSecOps

integrating security with every part of the development process

For years, teams pushed hard to deliver software faster. In that rush, security often came later, sometimes after most of the work was done. By then, fixing issues was costly and time-consuming.

That approach doesn’t work anymore. A small gap in code security can now become a big risk, especially with more cloud apps and open-source tools.

Organizations are adopting DevSecOps to address this issue. DevSecOps is a working style that blends security into each phase of the software development process.

This blog explains DevSecOps, why it is important to use it in software development, and how security is integrated in every part of the development process.

What is DevSecOps?

DevSecOps (short for development, security, and operations) is a software development approach that incorporates security considerations throughout the entire software development lifecycle (SDLC), but not just at the end.

In many software development teams, developers just focus on writing code, operations teams handle deployment, and security is added at the end. But that makes it harder to fix security-related problems later.

DevSecOps is an evolution of DevOps practices that encourages developers, testers, security staff, and operations teams to work together. This makes security a shared responsibility of all team members. Its main aim is to automate security testing and vulnerability detection by making it a part of the CI/CD pipeline.

With the rise of cyberattacks, it is very important to adapt to DevSecOps practices early to deliver reliable and secure applications to end users.

DevSecOps vs DevOps: What’s the Difference?

Aspect
DevSecOps
DevOps
Overall Approach
It integrates security at every stage of the software development workflow. It encourages the security teams to work together with the development and operations teams.
DevOps refers to the cultural practices for software development, which encourage software development and operations teams to work collaboratively for the quick delivery of software.
Primary goal
Focuses on fast delivery while keeping security checks active throughout the process.
Its main aim is to enable quick application development and deployment through automation.
Who Handles the Security
Developers, testers, operational teams, security teams, etc., all have a shared responsibility to handle security.
Mostly, security teams handle the application security at the end of the development cycle.
Process Flow
Security checks are done in every stage, including code writing, testing, building, deployment, etc., through automation.
Code is developed and tested first. Later, it is checked for vulnerability issues.
Tools Required
DevSecOps requires tools that are needed in DevOps and additional tools for security checks.
DevOps requires tools for CI/CD monitoring, automated testing, etc.

Why DevSecOps Matters Today

According to the recent survey done by Grandview Research, the global DevSecOps market size was valued at USD 8.84 billion in 2024 and will grow at a 13.1% CAGR from 2025 to 2030. This shows that automated security testing is becoming essential in software development processes.

Other than this, DevSecOps is used across multiple industries to meet strict compliance requirements, including:

  • Healthcare: With DevSecOps practices, software development teams can build applications that follow HIPAA compliance to secure patients’ data.
  • Government Projects: Applications that handle government data can be the first target for cyberattacks. By introducing the DevSecOps methodology during software development, teams can save applications from cyber threats.
  • Finance: In the finance industry, DevSecOps ensures that software with payment gateway integration follows PCI-DSS compliance when handling customers’ transaction data.

What Are the Benefits of DevSecOps?

DevSecOps isn’t only about keeping code safe. By building security into the daily workflow, many of the usual headaches, like rushed fixes or last-minute reviews, can be avoided.

Here are a few key benefits of introducing DevSecOps practices in the software development workflow:

  • Spotting Issues Early: Teams can catch weak spots in the code while it’s still being written or tested, before anything reaches the user.
  • Quicker Delivery: When security checks run automatically during builds, it removes delays caused by long review cycles.
  • Lower Compliance Risks: Software used in regulatory industries like healthcare, aerospace, etc., needs to follow security compliance standards, and DevSecOps always helps with this.
  • Cost Saving: By fixing critical bugs in the early stages, teams can save on development costs.

Core Principles of DevSecOps

  • Shift-Left Approach: DevSecOps was introduced based on the shift-left security approach. It states that security checks should not be done at the end, but teams should begin reviewing risks as soon as features are planned or code is written. This way, teams can identify threats in the software’s design and development phase.
  • Security as Code: Rather than setting up policies for security checkups manually, teams should write them in code format. This way, teams can reuse policies and update and track past versions with version control systems.
  • Security Automation: DevSecOps encourages teams to automate the security checks using the SAST, DAST, and IAST tools with CI/CD pipelines to detect potential bugs automatically.
  • Continuous Monitoring and Response: It is very important to use the DevSecOps tools to continuously monitor the security of the application after it is deployed. This can help teams identify security issues like strange traffic or failed login attempts.
  • Collaboration and Communication: DevSecOps encourages different teams, including development, security, and operations, to work together and openly communicate to solve any issues.

How Security Fits into Every Step of the DevOps Pipeline

In software development, the CI/CD pipeline has multiple stages, and each stage follows the security guidelines. Here is how:

Code & Development

While using DevSecOps, security implementation starts from the coding and development phase. Teams are required to write code in secure and trusted components and ensure that code reviews are implemented to catch hardcoded logic, outdated libraries, etc.

Build & Integration

Once the code is written and committed, teams should use automatic tools to build it. These tools can identify outdated third-party packages or risky changes and validate the configuration files. If the code changes don’t follow pre-set security standards, the build fails and shows an error message.

Testing

Automation testing is used to test each code change. It uses different testing methods for input validation, testing features, and checks for data leaks.

Deployment

Teams once again evaluate the code at this stage before deploying it. They need to review firewall rules, API settings, and access control. Deployment tools can stop the operations if any issue occurs.

Monitoring

Once the code is in production, employ ongoing monitoring tools to find security risks, unauthorized access, etc.

Using Modern Requirements4DevOps to Support DevSecOps from the Start

In the DevSecOps culture, security integration starts from the software planning phase. If the software requirements aren’t traceable or analyzed for risks, it can cause issues later.

That’s why it is very important to connect security expectations with work items, including user stories, test cases, features, etc., and for that, you need a proper requirements management tool.

Modern Requirements4DevOps offers key features like traceability, version control, change management, risk analysis, document management system, etc., that can help teams prepare requirements that follow security compliances.

If you are already using Azure DevOps or plan to, it’s worth exploring how Modern Requirements can help you manage requirements and risk without slowing your team down.
