• Integrate Nessus with security and infrastructure technologies using APIs, vendor integrations, and custom scripting.
• Collaborate with Security Operations, Infrastructure, Application, and other technical teams to coordinate and drive vulnerability remediation.
• Develop and maintain technical architecture, implementation, configuration, testing, operational, and support documentation.
• Provide technical recommendations related to Nessus capabilities, modules, configuration options, upgrades, architecture, and enhancements.
