DevSecOps vs. DevOps: Key Differences Explained
DevOps focuses on speed and collaboration between development and operations teams to deliver software efficiently. DevSecOps builds on DevOps by embedding security into every stage of the development process, ensuring vulnerabilities are addressed early and continuously.
Key Takeaways:
- DevOps: Prioritizes speed and automation, with security handled after development.
- DevSecOps: Integrates security throughout, balancing speed and safety.
- Fixing security issues early is 30x cheaper than after release (IBM research).
- Cyber threats and regulations like GDPR and HIPAA make DevSecOps essential.
Quick Comparison:
| Aspect | DevOps | DevSecOps |
|---|---|---|
| Security Timing | After development | Throughout the lifecycle |
| Team Focus | Dev + Ops | Dev + Ops + Security |
| Testing Priority | Functional, performance | Security + Functional + Performance |
| Responsibility | Dedicated security team | Shared across all teams |
If speed is your priority, DevOps works well. But for sensitive data, compliance, or stronger security needs, DevSecOps is the better choice.
DevOps vs. DevSecOps: Basic Concepts
DevOps Core Elements
DevOps reshapes how software is delivered by merging development and operations into a unified workflow. It emphasizes speed, teamwork, and automation to speed up software delivery while ensuring reliability. At its core, DevOps relies on continuous integration and delivery (CI/CD). This fast-paced model lays the groundwork for the security-focused additions introduced by DevSecOps.
DevSecOps Security Integration
DevSecOps takes the DevOps framework and embeds security into every step of the development process, making it a priority from the very beginning.
"The time to market is shorter every year and older security practices slow down development. Teams had to find a way to speed up without compromising security. This is how DevSecOps started. The ultimate goal is to unite security teams and developers while ensuring fast, safe delivery of code."
- Sonatype‘s 2020 DevSecOps Community Survey
This approach involves ongoing security testing and monitoring, starting from the planning phase and continuing through deployment. These changes in how security is handled directly influence the tools and methods used – which we’ll dive into next.
Key Differences Overview
Here’s how DevOps and DevSecOps differ:
- DevOps prioritizes speed and efficiency in the development cycle.
- DevSecOps weaves security into each phase, with a focus on continuous testing.
- DevSecOps requires expertise in security tools and identifying vulnerabilities.
- Unlike DevOps, DevSecOps incorporates security during the build process, not after development.
With DevSecOps, the mindset shifts to "move fast, but fix as you go". This contrasts with the traditional DevOps approach of "move fast and fix later." The difference underscores how DevSecOps integrates security into every stage rather than treating it as an afterthought.
Security in Development Cycles
DevOps Security Steps
In traditional DevOps, security is often treated as an afterthought, only addressed once the code is fully developed. This delay can lead to vulnerabilities slipping through the cracks. A stark example is the 2021 Colonial Pipeline ransomware attack, which disrupted fuel supplies across the U.S. and underscored the dangers of postponing security measures.
Here’s how security typically unfolds in a traditional DevOps workflow:
- Development teams complete the code.
- Operations teams deploy the code and test its functionality.
- Security teams then step in to assess vulnerabilities.
- Any issues found are resolved post-deployment.
This reactive approach can leave systems exposed during critical stages.
DevSecOps Security Steps
DevSecOps takes a different route by embedding security into every phase of development. Using a ‘shift-left’ strategy, security checks start early and happen continuously. This requires a change in mindset, fostering collaboration among developers, operations, and security teams from the get-go.
Consider the case of a major retail company. After suffering a data breach caused by a missed payment gateway vulnerability, they moved from a traditional DevOps model to DevSecOps. By integrating security scans into their CI/CD pipeline, they caught vulnerabilities earlier and avoided similar incidents.
This integrated approach ensures that security becomes part of the process, not just an afterthought. The next sections will dive into the tools and techniques that make this possible.
Team Structure Changes
The move from DevOps to DevSecOps also brings changes to team roles and responsibilities. Here’s how the structures differ:
| Aspect | DevOps Structure | DevSecOps Structure |
|---|---|---|
| Security Ownership | Mainly handled by a dedicated security team | Shared responsibility across all team members |
| Skill Requirements | Focused on development and operations | Includes additional security expertise |
| Communication Flow | Linear (development → operations → security) | Circular (continuous collaboration) |
| Testing Responsibility | Mostly managed by QA and operations teams | Involves the entire team |
To succeed in this model, teams need to develop skills in:
- Secure coding
- Detecting vulnerabilities
- Automated security testing
- Ongoing monitoring
A study analyzing over 5 million static scans found a 143% rise in small applications using automated security testing, reflecting the growing emphasis on proactive risk management. These team adjustments set the stage for exploring the tools that power this collaborative approach.
Tools and Methods Comparison
DevOps Pipeline Tools
DevOps prioritizes automation and efficient deployment through continuous integration and delivery platforms. Here’s a breakdown of key DevOps pipeline components:
| Tool Category | Common Tools | Primary Function |
|---|---|---|
| CI/CD | Jenkins, GitLab CI/CD, GitHub Actions | Automates building and deploying code |
| Infrastructure as Code | Terraform, Ansible | Automates infrastructure management |
| Containerization | Docker, Kubernetes | Manages application containers |
| Monitoring | Prometheus, Grafana | Tracks system performance |
On top of these essential tools, DevSecOps broadens the scope by embedding security into each step of the pipeline.
DevSecOps Security Tools
DevSecOps enhances traditional DevOps practices by integrating security measures at every stage of the process. This approach can significantly reduce vulnerability remediation costs – up to 30 times less than fixing issues after release. Adoption rates for security-focused tools are also increasing:
- 50% of teams use Static Application Security Testing (SAST)
- 44% employ Dynamic Application Security Testing (DAST)
- 50% regularly scan containers and dependencies
Tool Requirements List
The shift from DevOps to DevSecOps requires additional tools that support seamless integration and advanced automation. Here’s a comparison of tool requirements:
| Requirement | DevOps Tools | Additional Security Tools |
|---|---|---|
| Code Analysis | Basic linting tools | SAST (e.g., Veracode, Checkmarx) |
| Testing | Functional testing | DAST, IAST, Penetration testing |
| Monitoring | Performance metrics | Vulnerability scanning, Compliance monitoring |
| Deployment | CI/CD pipelines | Security gates, Policy enforcement |
While DevOps tools focus on speed and automation, DevSecOps tools ensure security is a core part of the process – delivering fast deployments while minimizing risks.

| Role | Security Responsibilities |
|---|---|
| Security Engineers | Conduct threat modeling and perform security testing |
| Developers | Follow secure coding practices and address vulnerabilities |
| Operations | Monitor security and manage patches |
| Security Champions | Advocate for and implement security practices across teams |
This structure emphasizes collaboration and integrates security into every stage of the workflow.
Common Transition Issues
Shifting from DevOps to DevSecOps isn’t always smooth. A major hurdle is the lack of security expertise within existing teams. Developers may not be familiar with secure coding practices, and operations teams often lack experience with security automation tools. Additionally, teams accustomed to fast deployments might resist security measures that could slow down delivery.
To address these challenges:
- Provide focused training to fill security knowledge gaps.
- Integrate security tools directly into CI/CD pipelines to maintain efficiency.
- Foster a culture where security is seen as everyone’s responsibility.
