Services
Network segmentation. Hardening. Change control.
Access control, infrastructure hardening, and operational handoff — backed by electronics, ERP, and a networking / security path.
01
Network segmentation
Document the live network — VLANs, access, and dependencies — so guest, cameras, voice, and production are not on the same blast radius.
The problem
The real network lives in a few people’s heads. Guest Wi-Fi, cameras, phones, and production sit on the same broadcast domain until something breaks.
In practice
- Sit with the people who run it and the gear that actually does the work.
- Document VLANs, ACLs, access, and dependencies so the next person is not guessing.
- Keep that record current when the environment changes.
Best fit. IT and operations teams who need someone who has already lived inside live systems — electronics, RF, and a logistics ERP — not only a classroom lab.
02
Infrastructure hardening
Find the gap, test the control against a written spec, and write up what failed — MFA on VPN, camera VLAN isolation, UPS on the core.
The problem
A walkthrough can pass and the requirement still is not met — open guest Wi-Fi on the camera VLAN, no MFA on VPN, no UPS on the core.
In practice
- Trace a problem to hardware, config, or process instead of treating the symptom.
- When a control fails, write it up so it can be fixed. Failure in testing is the work.
- Sign off when the result matches the criteria we already agreed on.
Best fit. Teams who need someone who already troubleshoots, documents, and checks their work before it goes back to the user.
03
Change control and handoff
Leave SOPs and a change window, not a single person who holds the router login. The work is done when the team can run it.
The problem
One person knows the firewall, the VPN, and the camera NVR. Everyone else waits. Risk sits on that person’s calendar.
In practice
- Write runbooks people can use on their own the first week.
- Walk through the change once, then let the team run it.
- Keep materials current when the environment changes.
Best fit. Teams that want the next person productive without a private tutorial every time.
