Cisco Firewall, Router & Switch Tune-Up and continued Maintenance -- 2

Budget: $50+/hr

Several Cisco ASA firewalls, ISR routers, and Catalyst switches keep our network running, but they have not been touched in a while. I need a thorough tune-up that covers three areas: installing the latest stable software patches, reviewing every running-config for performance tweaks, and hardening the security posture against current threats.

Partial documentation exists—mainly topology diagrams and some old configuration notes—so part of the engagement is to validate what is still accurate and fill in the gaps.

Scope and expectations • Apply current Cisco software/firmware updates after confirming compatibility. • Analyse and refine interface, routing, VLAN, and policy settings to eliminate inefficiencies. • Conduct a focused security assessment (AAA, VPN, ACLs, logging, remote-management) and implement agreed hardening steps. • Produce clean, updated documentation that includes device inventories, final configs, and a concise change log.

Success criteria ✔ All devices boot on the new images without errors. ✔ Benchmarked latency/throughput matches or improves on pre-maintenance values. ✔ No critical or high vulnerabilities are flagged by the post-change scan. ✔ Updated documentation is complete enough for another engineer to restore or replicate the setup.

Access can be provided through scheduled remote sessions; on-site work is possible later if the first phase shows it is required.
