IT services built around how Irvine businesses work
Irvine concentrates exactly the kinds of businesses where IT failures are expensive: medical and dental practices, CPA and tax firms, law and financial offices, and technology and life-science companies: spread across the Irvine Business Complex by John Wayne Airport, the Irvine Spectrum, and the office parks between them. We support Irvine organizations including:
- Medical, dental and specialty practices
- CPA, accounting and tax preparation firms
- Law, insurance and financial services offices
- Technology, engineering and life-science companies
- Multi-location businesses with an Irvine headquarters
- Growing companies moving into their first real office
The IT problems we see most in Irvine offices
The questions Irvine clients bring us are rarely about a single broken laptop. They tend to be about the building, the growth, or the regulator.
Multi-tenant buildings you do not control
Much of Irvine's office space is multi-tenant, where the telecom room and cable risers belong to building management. We coordinate with property managers and your internet provider on circuits and access, and our in-house low-voltage team handles the cabling inside your suite.
Outgrowing the office IT person
A firm that grew from 10 to 40 people often still relies on one person who 'is good with computers'. We either take IT over fully, or become the team behind that person so they are not carrying security and after-hours coverage alone.
Compliance that comes with the clients
Irvine medical practices answer to HIPAA; tax preparers to the FTC Safeguards Rule. We put the required safeguards, logging and documentation in place and keep them current, rather than treating compliance as a yearly scramble.
Staff split between the office and home
Hybrid teams need secure remote access, protected identities and managed devices wherever people work, without making the office network the weak point.
Phishing and ransomware
New clients often come to us in the middle of an incident, usually started by a phishing email. We contain it, clean it up, secure the environment, then fix what allowed it so it cannot happen the same way again.

On-site in Irvine when you need it
Our Orange County office is in Orange, a short drive from Irvine. About 95% of issues are resolved remotely, which is almost always the fastest fix. When something needs hands on equipment (a failed switch, a new office, a server room) we send a North Blue engineer to your Irvine office, not a subcontractor.
How we prioritize your requests
Every request is triaged by how much it is costing your business. These are the response targets we work to, published as our process rather than a contractual guarantee.
Critical: about 1 hour
The office is down, a server has failed, or a location cannot connect.
High: about 2 hours
Key people or key software are blocked, but work can partly continue.
Medium: about 4 hours
One person is affected and has a workaround.
Low: about 8 hours
Something is slow or needs setting up, but nothing is stopped.
Why Irvine businesses choose North Blue
We have been running IT for Southern California businesses since 1996. Our average client has stayed with us for more than 10 years, and our longest relationships have passed 25. Our practices are aligned with NIST, CIS, ISO/IEC 27001, SOC 2, PCI DSS, GDPR, CCPA and GLBA. And our consultants will tell you when a purchase is not worth it. We would rather keep a client for a decade than sell them something once.
