A bit about the role

In addition, you will build and maintain strong relationships with external vendors and managed security service providers to support incident response activities, ensuring SLA compliance and effective collaboration during critical events. You will stay current with emerging threats and adversary tactics, techniques, and procedures, and integrate threat intelligence into response strategies to strengthen nbn’s overall cyber defence posture.
