Blue Team Analyst · Vulnerability Management
You can't patch everything at once. Learn what to fix first.
In our Blue Team Analyst programme you run a vulnerability scan, prioritise the output with CVSS, EPSS and asset criticality, and track remediation to closure with the teams who own the fix.
- Read scanner output properly
- Prioritise with CVSS, EPSS and asset criticality
- Track remediation to closure
