if you want a simple DevSecOps definition, it is short for development, security, and operations. Its mantra is to make everyone accountable for security with the objective of implementing security decisions and actions at the same scale and speed as development and operations decisions and actions.
Automation is good
DevOps is all about speed of delivery, and this doesn’t need to be compromised just because you are adding security to the mix.
Use DevSecOps for efficiency
You are only adding security to your workflows. By using tools that can scan code as you write it, you can find security issues early.
