- Cisco Firepower Management Center (FMC)
- Carry out software upgrades, patching, and lifecycle refresh activities across network and security platforms
- Ensure systems remain secure, compliant, and aligned to strict operational standards
- Maintain strong security controls, including segmentation, access policies, and device hardening
- Proactively identify and resolve risks to availability, performance, or security
- Implement controlled changes in line with rigorous governance and audit requirements
- Support incident resolution and TAC escalations when needed, with a focus on fast recovery and preventing recurrence
- Keep documentation and audit records accurate and up to date
