Modern software builders need to reduce risk and confidently ship. In an ever-shifting tech landscape, that’s harder than ever.

This is why we built CircleCI: the CI/CD platform that makes it easier for developers to win at software.

At CircleCI, we know that velocity must go hand in hand with building securely. World-class engineering teams don’t sacrifice security for speed but rather choose CircleCI to deliver both.
Our product philosophy for our customers has eight pillars:

1. Security for all: We believe that security features should be accessible to all customers, regardless of their plan level.

2. Unobtrusive security: We design security features to be intuitive and easy to use and believe most of all they must not interfere with the user experience.

3. Secure by default: We build secure defaults out of the box.

4.Traceability: We believe visibility can drive accountability.

5.Store of no value: We strive to minimize the amount of valuable or sensitive data stored.

6. Fail securely: When we fail, we fail securely.

7. Least privilege: We grant users and systems only the minimum level of access necessary to perform their intended functions.

8. Complete mediation: We ensure that all user actions are fully authorized and authenticated at all times.

CircleCI enables developers to build faster, more secure, and more reliable pipelines, without needing to be a CI/CD expert. As a result, teams building on CircleCI regularly achieve elite software delivery benchmarks.
