We maintain global hybrid instances of our chosen tools for SIEM, Application Performance Monitoring, Log Monitoring, Backlog Management, Identity Access Management, Service Desk, self-help portals for colleagues and incident communications. In addition to the challenges delivering this capability brings, we're also the team responsible for the security operations centre and our security architecture, working across Tesco globally to secure our systems and data!
