  • Understand what the business needs from technology

  • Manage, document, and improve the environment over time

The password taped to the register is a security risk wearing a welcome sign. Free guest Wi-Fi is expected everywhere now — but an open, unbranded network also hands every visitor a generic experience and puts your point-of-sale, cameras, and files one bad click away from a stranger’s laptop. We build branded guest Wi-Fi hotspots with custom captive portals: the polished login screen your customers see, with your logo and your rules, on a network safely separated from your business systems.

A captive portal is the welcome page guests land on before they get online — the same experience you see at hotels and airports, tailored to your business. We design the portal, set up the guest network behind it, and make sure the whole system runs itself: guests get easy, fast internet, and you get security, control, and a professional first impression.

What we build

  • Custom portal design — your logo, colors, photo background, and welcome message on the login page
  • Sign-in your way — simple one-tap access, terms-of-use acceptance, rotating passwords, front-desk vouchers, or email/SMS sign-in that builds your marketing list
  • Guest isolation & security — a separate guest network (VLAN) that cannot see your business systems, cameras, or registers
  • Bandwidth & session controls — speed limits and time windows so guest traffic never slows your operation
  • Terms & liability — an acceptable-use agreement guests accept before connecting
  • Analytics & marketing integration — visit counts and repeat guests, connected to your email marketing

Problems we fix

  • Guests and customers on the same network as your point-of-sale, cameras, and files
  • A Wi-Fi password on a sticky note that never changes and everyone in the neighborhood knows
  • Generic login screens (or none at all) where your brand should be
  • One guest streaming video and slowing down the whole business
  • No record of who used your Wi-Fi, and no way to turn visitors into repeat customers

Frequently asked questions

Is a captive portal annoying for guests?

Not if it is designed well — one tap or one accept, then online. The friction you remove with easy Wi-Fi comes back as brand impressions and marketing sign-ins.

Can the guest network really be kept separate from our systems?

Yes — a dedicated guest VLAN with its own rules. Guests get fast internet; they cannot see your registers, cameras, or files.

Do you support it after installation?

Yes. One local team designs the portal, installs the network, and supports it afterward — the same people pick up the phone.

The experience behind it

We run enterprise-grade platforms (including UniFi) for more than 100 Los Angeles locations, so your hotspot is built on the same professional equipment hotels and campuses use — not a consumer router with a plug-in.
