  • Familiarity with vulnerability management and ticketing platforms (ServiceNow, Jira, Azure DevOps, or similar).
  • Experience leveraging scripting, automation, APIs, or AI-assisted workflows (Python, PowerShell, LLM-based tooling, etc.).
  • Certifications such as GPEN, OSCP, PenTest+, or equivalent industry-recognized credentials.
