A no-nonsense introduction to DevSecOps

DevSecOps is usually either overcomplicated or understated in the way its communicated. Here's a simple, no-nonsense take at it.

The financial losses occurring from cybercrime have risen from USD 3 Trillion in 2025 to USD 6 Trillion in 2021 and are projected to reach USD 10 Trillion in 2025.

That's already double the size of the Indian Economy. If cybercrime was a country, it would be the third-largest economy in the world.

Safe to say — software security has become a big deal, and traditional approaches just aren't cutting it anymore.

DevSecOps is a philosophy or approach that software engineering teams can leverage to strengthen the guardrails around their software and minimise losses from any breach. This methodology has security baked right into its core.

DevSecOps is a mashup of "Development," "Security," and "Operations," and it integrates security best practices throughout the entire software development process.

Instead of dealing with security measures after development, DevSecOps builds upon the collaborative, automated, and continuous delivery principles of DevOps to make sure security is front and centre from the get-go.

The main idea behind DevSecOps is that everyone's got a part to play in keeping things secure, not just a dedicated security team. This means developers, operations folks, and security gurus all work together right from the start, ensuring security is woven into every stage of development.

This teamwork makes it possible to catch and fix vulnerabilities early on, reducing the risk of security breaches and avoiding the financial and reputation mess they can cause.

But wait, how do we do all this?

It’s done in a two-pronged approach.


Automation is the name of the game in DevSecOps. By automating processes like vulnerability scanning, code analysis, and compliance checks, the development process gets streamlined, and security checks are consistently applied at every stage. Plus, automation reduces the chances of human error and gives developers and security teams more time to tackle complex, strategic tasks.

Building Continuous Integration and Continuous Deployment Pipelines for developers to frequently ship newer, improved versions of the software is a standard way to achieve automation.

Lately, even the provisioning of cloud infrastructure resources (with security in mind) has also been automated via a methodology called GitOps.

Continuous Monitoring

Continuous monitoring is another key aspect of DevSecOps.

Real-time monitoring and analytics tools help identify potential security issues as they come up, allowing organisations to proactively tackle vulnerabilities before the bad guys can take advantage.

By continuously observing and analysing the environment, tech teams can proactively identify potential security threats, vulnerabilities, and misconfigurations in real-time, enabling them to respond quickly and minimise the impact of security incidents.

So, what's in it for organisations that embrace DevSecOps?

Quite a bit, actually:

  1. Better security: Integrating security best practices throughout development means organisations can seriously reduce the risk of breaches and keep sensitive data on lockdown.
  1. Quicker time-to-market: Automation and collaboration between development, operations, and security teams streamline the whole process, getting products out the door faster.
  1. Cost savings: DevSecOps helps cut costs tied to security incidents, like cleanup efforts, legal liabilities, and damage control. Plus, catching security issues early on saves time and resources in the long run.
  1. More customer trust: When customers know their data and info are well-protected, they're more likely to stick around and keep coming back for more.

In a nutshell, DevSecOps is a modern approach to software development that takes security seriously from the beginning.

It's helping organisations create software that's more secure, reliable, and ready to take on the challenges of today's digital landscape.

As technology continues to evolve, DevSecOps will play an increasingly important role in keeping organisations ahead of the curve and protecting against emerging threats.
