The two methodologies that have emerged as game-changers in the world of software development and IT Operations are DevOps vs DevSecOps. While DevOps primarily focuses on fostering collaboration between the development and IT teams, DevSecOps brings an additional layer of security into the mix.
In this article, we will discuss the specific nuances of DevOps and DevSecOps, understand the similarities between the two approaches, explore the differences, and finally discuss which approach is best for your business.
What is DevOps?
DevOps is an organizational approach that fosters collaboration and communication between development (Dev) and IT operations (Ops) teams. It aims to break down silos, in which the development and operations team traditionally operate in, and establish a sense of shared responsibility throughout the entire software development lifecycle.
It enables organizations to deliver high-quality software faster and with greater efficiency, by emphasizing on automation of repetitive tasks, such as testing and deployment. Additionally, continuous integration and continuous delivery (CI/CD) are key principles that DevOps teams abide by, which accelerates the product development lifecycle and allows businesses to rapidly deliver the requested features and updates.
What is DevSecOps?
DevSecOps is a relatively newer concept compared to DevOps. It actually expands upon the principles of DevOps by integrating security practices into the software development lifecycle and operations processes from the very beginning. DevSecOps promotes the idea that security is a shared responsibility among development, operations, and security teams, and it aims to build a culture of security awareness and collaboration.
It emphasizes a “shift-left” approach, where security is incorporated early in the development cycle rather than being an afterthought. By doing so, DevSecOps not only enables organizations to continuously deliver on the feature requests but also prevent the software from any vulnerabilities and security threats.

DevOps vs DevSecOps – Exploring the Differences
You can think of DevSecOps as an extension to the DevOps methodology. It expands on the main concept of DevOps with an element of security added to the mix. However, there still are some key differences between DevOps and DevSecOps and in this section, we will discuss those differences in detail.
Philosophy
The two distinct philosophies in software development, DevOps and DevSecOps, both have their own advantages and disadvantages.
DevOps emphasizes collaboration and communication between the teams and the breaking down of silos to speed up the development, deployment, and delivery processes. It focuses on automating workflows and fosters a culture of implementing continuous feedback. As a result, it accelerates the development cycle and makes the overall process more efficient. Hence, adopting DevOps is ideal for organizations that require rapid releases in short iterative cycles.
On the other hand, DevSecOps extends the DevOps philosophy by integrating security practices into every step of the software development lifecycle. This approach adheres to the idea that security is an integral part of software delivery and that everyone involved has a role to ensure the delivery of secure systems. The primary goal with this approach is not rapid delivery, but safety and security of the system. This makes it an ideal approach for organizations that are working with sensitive data or have strict compliance guidelines.
Goals
Traditionally, different teams operate in silos where each team plays a critical role in the line of command. Instead of moving down the line of command, DevOps brings all the stakeholders on the same page, and creates a sense of shared responsibility. As a result, this eliminates unnecessary handovers and delays and speeds up the entire process as a result. However, this requires a complete organizational shift, and it gets difficult to implement DevOps in large organizations with established processes and hierarchy.
In contrast, DevSecOps is a variation of DevOps. It shares the goals of DevOps but adds an additional focus on integrating security measures into software development and operations processes. However, since the primary objective here is to minimize the risk of vulnerabilities, organizations end up compromising on the delivery speed. Therefore, If you are a business that needs to move quickly to stay competitive and relevant, DevSecOps might not be suitable for your needs.
The primary goals of DevOps include improving software delivery speed, enhancing collaboration, increasing efficiency, and enabling continuous integration and delivery.
Emphasis
DevOps places emphasis on collaboration, automation, and efficiency. And as a result, it enables rapid and reliable software delivery. It mainly focuses on streamlining development and operations processes and fostering a culture of shared responsibility.
DevSecOps, however, places a strong emphasis on security from the outset. It integrates security practices and tools into the development and operations workflows to ensure that security is considered at every stage of the software lifecycle.
Security
While security is a consideration in DevOps, it may not receive the same level of attention as in DevSecOps. DevOps teams collaborate with security teams but may rely on their expertise for specific security-related aspects, and their primary goal still remains faster delivery.
Security is a core component of DevSecOps. Development, operations, and security teams work together to implement security controls, conduct security testing, and prioritize security measures throughout the software development lifecycle. As a result, when we talk about DevSecOps vs DevOps, DevSecOps is considered a more secure option.
Advantages
DevOps has numerous advantages, such as with the right practices in place, businesses can reduce their time-to-market and increase collaboration between their teams. DevOps practices create a sense of shared responsibility and shared common goal between the teams. The result is a highly efficient software development, testing, and deployment process.
DevSecOps offers all the benefits of DevOps while providing the added advantage of enhanced security. It helps organizations identify and address security issues early on before they become a potential threat. It reduces vulnerabilities and improves overall system resilience by proactively identifying and addressing issues as they arise.
Challenges
DevOps and DevSecOps, both are organizational approaches, which means that they require alignment of the teams. Overcoming the internal resistance to change could be the biggest challenge that organizations may face when adopting either of these approaches.
Additional challenges that organizations can face when adopting DevOps practices can include managing the DevOps process flow from different teams’ perspectives, creating CI/CD pipelines, and integrating suitable automation tools to meet organizational needs.
In addition to that, DevSecOps may encounter further challenges related to integrating security into existing workflows, balancing security requirements with development speed, along with ensuring collaboration and communication among multiple teams.
Skill Set
DevOps professionals require skills in areas such as automation, configuration management, continuous integration, continuous delivery, and collaboration and communication.
DevSecOps professionals possess skills in DevOps practices and tools, as well as expertise in security principles, secure coding practices, threat modeling, and vulnerability management.

Early stage businesses primarily focus on faster delivery times to gain competitive advantage. Therefore, for businesses focusing on rapid development and delivery of software, DevOps may be the ideal choice. DevOps allows organizations to respond quickly to market demands, iterate on software releases, and foster a culture of continuous improvement. In this phase, businesses may prioritize speed and agility, while ensuring a baseline level of security.
On the other hand, businesses that handle sensitive data, operate in regulated industries, or have a higher risk tolerance may lean towards DevSecOps. This approach ensures that security is not compromised and reduces the risk of security breaches. For businesses that prioritize security as a core aspect of their operations, DevSecOps provides the framework to embed security practices seamlessly, making it the right choice.
In conclusion, while DevOps and DevSecOps share similar goals of improving software delivery and fostering collaboration, they differ in their approaches to security. DevOps focuses on efficiency, automation, and collaboration, while DevSecOps extends these principles to include a strong emphasis on security throughout the software development lifecycle. Therefore, choosing between DevOps and DevSecOps depends on the specific needs and priorities of an organization.
