DevSecOps is the process of baking-in security practices into devops. We list over 100 tools that can help you to implement DevSecOps.

What is DevSecOps?

Devops with security baked in from the start

DevSecOps is the integrating of security practices into devops. A shorthand description is that security is “baked in” to the DevOps process, and not treated as another layer. Which means thinking about infrastructure and application security from the start and to include security as a key part of the application development lifecycle - using an operations-centric approach to vulnerability assessment via logging, event monitoring, configuration, patch, identity and privilege management.

A DevSecOps approach can be a driver of change in an organisation and because it applies to processes, people, and the tools that they use - it requires a change of attitude.

However, a key aim of applying a DevSecOps approach is not to slow down the DevOps process, the tension being that security and compliance should not be sacrificed for speed of development using continuous integration/continuous development tools.

DevOps organisations deploy code frequently, with shorter lead times, recovering from failures faster and spending less time addressing security issues. The implementation of security during development and delivery means less reliance on penetration testing and pre-production gate reviews.

It’s been reported that organisations that successfully embed security into DevOps experience a 50% drop in their production vulnerabilities and that their time to fix improves by 25%.

DevOps cycles through the following key phases:

  • Pre-commit
  • Commit / Continuous integration
  • Acceptance
  • Production
  • Operations

DevSecOps tools

The SANS Institute have mapped a number of open source security tools to the DevOPs phases outlining a DevSecOps toolchain and DevSecOps process summarised in the this poster:


Eric Johnson also walked through the first two phases in this presentation to the Australian Cyber Conference in Oct 2018.


Pre-commit checks are security activities used to find and fix common issues before changes are checked into source code repositories.

Threat modelling / attack mapping

  • Attacker personas are based on user personas and they describe the characteristics, capabilities and resources displayed by attackers . A number of different attacker personas represent an attacker landscape as well as various attacker types and threats to defend against.

  • Evil user stories an evil user story takes the viewpoint of a malicious adversary.

  • Mozilla Rapid Risk Assessment (RRA) The purpose of a Rapid Risk Assessment is to understand the value and impact of a service to the reputation, finances, productivity of the project or business, based on the data processed, stored or accessible by services.

  • OWASP Application Threat Modelling Threat modelling works to identify, communicate, and understand threats and mitigations within the context of protecting something of value. *OWASP ThreatDragon is An open source, online threat modelling tool from OWASP
