Awesome Cybersecurity Blue Team Awesome

A collection of awesome resources, tools, and other shiny things for cybersecurity blue teams.

Cybersecurity blue teams are groups of individuals who identify security flaws in information technology systems, verify the effectiveness of security measures, and monitor the systems to ensure that implemented defensive measures remain effective in the future. While not exclusive, this list is heavily biased towards Free Software projects and against proprietary products or corporate services. For offensive TTPs, please see awesome-pentest.

Your contributions and suggestions are heartily♥ welcome. (✿◕‿◕). Please check the Contributing Guidelines for more details. This work is licensed under a Creative Commons Attribution 4.0 International License.
