We’re just as particular about the details: every change is documented, every ticket is followed through to the finish, and our co-founders, Kevin Nichols and Joe Kemp, are personally accountable for your experience.

IT support built around Mission Viejo businesses

Mission Viejo has a large concentration of professional services firms, along with financial advisors, retail and service businesses serving south Orange County.

Professional and financial offices need protected data, reliable phones and systems, and fast help so staff can keep serving clients without interruption.

Mission Viejo’s business corridors, from Crown Valley to Alicia

Mission Viejo was planned with roads in the valleys and homes on the hills, so most of its commercial space lines a handful of parkways near the 5. The freeway has five interchanges in the city – Avery, Crown Valley, Oso, La Paz and Alicia – and the 241 connects at Los Alisos Boulevard. The Shops at Mission Viejo and the Kaleidoscope center sit across Crown Valley Parkway from each other, with Saddleback College close by.

The city’s top employers show how mixed the economy is. Saddleback College and two school districts rank near the top, alongside department and big-box stores, a building-products maker and a package delivery station. A restaurant chain keeps its corporate headquarters here.

For the professional and service firms in between, a few things come up again and again:

  • Shared office buildings — the wiring closet often belongs to the landlord. We document what you own, what you don’t, and how your network is kept apart from the suite next door.
  • Retail sites near the two shopping centers — card readers and guest Wi-Fi on separate networks, plus a cellular fallback for the busy weekend when the main line drops. See connectivity consulting.
  • Hybrid teams — many staff live in South County and work from home part of the week, so laptops, sign-ins and files are secured the same way in either place.

Who we work with in Mission Viejo

Mission Viejo is a South County hub for financial advisors and professional firms, many in the business centers around the Kaleidoscope area and the 5. Smaller offices here often want enterprise-grade security without hiring a security team, which is what our included SentinelOne MxDR and 24×7 SOC provide.
