“I am truly grateful to be a part of the Cobalt Core team. I can work alongside highly-skilled security professionals. Each project is different, and I can work with different technologies and industries. The ability to work with the product teams allows for great communication and collaboration. Giving us an outlet to ask questions, get them answered right away, get feedback in real-time, understand what areas are more critical to follow, and the customer is constantly updated with our progress, as well.”

Application Process

Our Core Members go through a rigorous application process. Here we go through each step of the vetting process so you know what to expect.

Stage 1
Application
Applications are reviewed by our community team based on tenure, skills, and expertise. The application portal can be found here.
Stage 2
Assessment
Once a pentester is selected from the application process they are sent our skills assessment to test technical abilities.
Stage 3
Vetting
After successful completion of the skills assessment, our team sets up a time to meet face-to-face and align on community expectations.
Stage 4
Verification
Once a pentester passes initial vetting, a background check is conducted by a third-party verification vendor. After successful completion, tax documentation, NDAs, and Cobalt Independent Contractor Agreement are signed and confirmed.
Stage 5
CONTINUOUS EVALUATION
Members of the Core are reviewed on a continuous basis. After each engagement, pentesters review teammates and receive feedback from peers and customers.
