Premium Pentesting.
at Your Fingertips.

No two applications are the same, just like no two pentests are the same. Cobalt brings the right combination of skills, performance and experience to fit your pentesting needs.

Our Vetting Process

Cobalt Core Pentesters are the best of the best. Each of our pentesters has gone through a strict vetting process that only admits the top 5% of applicants. These top performers make up our pentesting community, from which we hand-select the right person for your unique needs to handle your manual pentest.

Stage 1
Application
We receive both inbound applications as well as community and customer referrals. Applications are reviewed by our community team based on tenure, skill and expertise.
Stage 2
Assessment
Once a pentester is selected from the application process they are sent a Cobalt skills assessment to test their technical abilities.
Stage 3
Vetting
After successful completion of the skills assessment, our team will set up a time to interview the candidate as a way to meet face-to-face, and align on community expectations.
Stage 4
Verification
Once a pentester has passed initial vetting, they will be verified by a third party verification vendor. At this stage, tax documentation will be confirmed and NDAs and Cobalt Terms of Engagement will be signed.
Stage 5
Continuous Evaluation
Core team uses a secure VPN for testing. Their work is always peer reviewed by trusted leads and the core labs team.

Our Core Team

We draw on a Core of 400+ highly vetted, certified pentesters to find the right skills to match to your security requirements and business needs.
