DevOps vs DevSecOps is a question that often sparks lively debate among IT industry professionals. But how do they differ, and which approach to software development is best for your organization?
The similarities between the two terms often lead to some confusion, but although they share many traits, DevOps and DevSecOps are subtly distinct practices. While DevOps generally treats security as a separate process, the DevSecOps model, quite literally, places security front and center.
In this article, we will outline the key differences in the DevOps vs DevSecOps debate and arm you with the knowledge needed to make an informed decision about which approach to invest in to improve your organizationβs security posture.
DevOps: Speed and Collaboration
The term βDevOpsβ stands for βDevelopment and Operations.β It is a modern approach to software creation that combines typical coding and development activities with IT operations and quality assurance.
DevOps aims to speed up the software development process by focusing on frequent release cycles, efficient communication and collaboration among team members, and the use of automation technologies to streamline operations.
Historically, development and operations were treated as separate entities. Under the traditional Waterfall model, for example, the developers wrote the code while the system administrators took charge of its integration and deployment.
However, as newer methodologies such as Agile came to the fore, a fresh approach was needed. This was, in part, due to the sprint-led nature of these new models, which emphasized the need for more frequent software releases (ranging from once every few weeks to multiple times a day).
DevOps was the ideal solution to address the evolving demands of software development, as it seamlessly joined the dots between planning, coding, testing, deployment, and monitoring.

Today, DevOps has become so ubiquitous that it is often used as shorthand for all the βdoingβ of modern software development β from the coding of programs and applications to software deployment and backend operations.
The Guiding Principles of DevOps
The term βDevOpsβ was coined in 2009 by Patrick Debois. Since then, the approach has been adopted by organizations of all sizes.
The key principles of DevOps include:
- Rapid software releases through automation
At its core, DevOps aims to speed up the software development lifecycle. Long gone are the days of the Waterfall model, where development could be held up due to each phase being dependent on the completion of the previous one. Using Continuous Integration and Continuous Delivery (CI/CD) platforms and other automation tools, DevOps focuses on short, sharp release cycles. These deployments can range from once every few weeks to several times per day, leading to continuous improvements and efficiency at scale.
- Collaboration and communication
DevOps also places a strong emphasis on collaboration and communication. Rather than having teams across the business working in silos, all stakeholders are encouraged to work collaboratively and maintain a holistic understanding of the organizationβs goals. In turn, a strong DevOps culture leads to increased productivity and a better working environment.
- Focus on customer needs
One further benefit of DevOps is that the short release cycles allow development teams to make fast, iterative changes and improvements to their codebase. Now, instead of having to wait weeks or even months for changes to be made, new features or bug fixes can be implemented quickly. Making rapid improvements based on feedback from customers or internal stakeholders is vital in todayβs highly competitive technology space.
- Continuous improvement and βfailing fastβ
The fast-moving and agile nature of DevOps allows any changes to be rolled back just as easily as they are implemented. This allows teams to βfail fastβ and prevents any software bugs or operational issues from having a long-term impact on the team.
DevSecOps: Integrating Security into DevOps
DevSecOps stands for Development, Security, and Operations. Building on the successful DevOps model, DevSecOps is an approach to culture, automation, and platform design that treats security as a shared responsibility throughout the entire IT lifecycle.
DevSecOps aims to reduce the number of security issues going into production by catching them at an earlier stage in the development process.
DevSecOps engineers typically test and monitor a companyβs system for vulnerabilities on an ongoing basis. They will collaborate with program developers to patch any holes in the current security program, add countermeasures to prevent new threats, or make the program stronger and more effective.
Application security is already a mainstream skill and is heavily in demand, but DevSecOps is a rising star. Gartner indicates that DevSecOps is in the early stages of mainstream adoption. They quote a 20%-50% market penetration among DevSecOpsβ target audience.
Gartner projects that DevSecOps will reach mainstream adoption within one to four years. Indeed, this approach is currently being used by many leading companies, including Amazon, HP, and Netflix.

Key Goals of DevSecOps
DevSecOps inherits many of the guiding principles of DevOps but with an even sharper focus on improving an organizationβs security posture.
DevSecOps teams will focus on the following:
- Security as a shared responsibility: Rather than the security responsibility falling under the remit of one or two specialist employees, a culture of security awareness is engrained across all members of the software development team.
- Secure coding best practices: Security is never treated as an afterthought. Secure coding best practices are integrated throughout the development process.
- Implementation of security automation: Continuous security monitoring is achieved through security automation tools. This means potential bugs or vulnerabilities can be mitigated quickly.
DevSecOps: What does βshift leftβ mean?
The term βshift leftβ is commonly associated with DevSecOps. It emphasizes how security testing activities have been moved to an earlier stage of the development process.
Within the DevSecOps model, security is integral to the entire software lifecycle, and βshifting leftβ is a synonym for organizations seeking to embrace these goals.
The βshift leftβ trend is further illustrated by the fact that security itself is embedded within DevSecOps as an industry term.
DevOps vs DevSecOps
DevOps and DevSecOps share many core traits, but they each offer a nuanced approach to software development. These similarities and differences are highlighted in the table below:
The Differences Between DevOps vs DevSecOps | |
---|---|
DevOps | DevSecOps |
Combination of development and operations | Integration of security into DevOps practices |
Rapid software delivery and continuous feedback | Faster and more secure software delivery |
Collaboration, automation, CI/CD | Collaboration, automation, security integration |
Emphasis on speed, efficiency, agility | Emphasis on security, risk mitigation, compliance |
Basic security measures; security is addressed later in the process | Security is βshifted leftβ and addressed at an earlier stage |
The DevOps vs DevSecOps debate is often reduced to one of speed and collaboration vs security integration.
However, while it is true that the added security focus of DevSecOps may result in a slightly slower product delivery, the fact that security bugs are ironed out at an earlier stage means that, in the long term, these time savings are negligible.
Likewise, although DevOps practitioners generally treat security as a separate, rather than parallel, process, this doesnβt mean it is discounted entirely.
For example, according to Googleβs State of DevOps 2022 report, 63% of organizations surveyed said they used application-level security scanning as part of their CI/CD delivery.
The report stated:
βOverall, we found surprisingly broad adoption of emerging security practices, with a majority of respondents reporting at least partial adoption of every practice we asked about.β
