@brandoncox

I support mission-critical Army networks and teach hands-on Cisco networking and cybersecurity procedures.

At Bravura, I deliver hands-on CCNA training in Cisco routing, switching, IPv4/IPv6, VLANs, OSPF, ACLs, NAT, DHCP, network security, and systematic troubleshooting. I build IOS-based labs and translate complex networking concepts into practical enterprise and DoD procedures.

In the U.S. Army, I maintain battalion communications and network infrastructure, resolve Layer 1–3 connectivity issues, and safeguard controlled communications equipment as a COMSEC Custodian. I bring earlier Tier 1 support and healthcare systems experience, along with CCNA and CompTIA Security+ certifications.
