Networking and Infrastructure

Security-first networking without the jargon. We separate guest, staff, and payment systems, document what talks to what, and lock it down so outages are rare and audits go smoothly.

Outcomes

  • Clear separation of guest Wi-Fi, staff systems, and payment/PCI zones
  • Only the traffic your business needs is allowed — everything else is blocked
  • Reliable service: fewer “mystery” outages and faster troubleshooting
  • Audit-ready evidence for PCI and internal reviews
  • Simple explanations your team can follow and maintain

What we deliver

  • Network & data-flow diagram: who talks to what, and why
  • Zone policy matrix (guest, staff, vendor, payment) with allowed ports
  • Firewall/ACL baseline and rule cleanup list with plain-English reasons
  • VLAN & IP plan with clear naming and standards
  • Secure remote/vendor access plan (MFA, jump host, time-bound access)
  • Evidence pack: screenshots/exports and change logs for auditors

How we explain the complex—simply

Segmentation
Think “separate lanes.” Guests, staff, and payment systems don’t share the same lane, so problems stay contained.
Traffic rules
Only approved connections are allowed. Everything else is denied by default and logged.
Layers (OSI/TCP)
We tie issues to the right layer (cable, switch, IP, ports, app) so fixes are quick and targeted.
Change safety
We schedule changes, back up configs, and keep a rollback ready so operations don’t stall.

FAQ

Does a VLAN automatically make me secure?

Not by itself. Real separation comes from clear rules at the firewall/router level that only allow what your business needs.

Will this break my POS or vendor systems?

No. We stage changes, coordinate with vendors, and use rollback plans so transactions keep moving.

How does this help with PCI?

We shrink and protect the cardholder-data zone, limit access, and provide the evidence your QSA asks for.

Do you support our gear (Meraki, Aruba, Ubiquiti, etc.)?

Yes. We work with your stack and apply the same security principles across it.

What do you need from us to start?

A short call and read-only access to configs/portals. We take it from there and stay out of the way of operations.
