About Emerald Security

Local roots. Enterprise capabilities.

Organizations shouldn’t have to choose between the personal attention of a local technology partner and the expertise of a large IT firm. We built Emerald Security so they don’t have to.

Who we are

A Northern California IT company that answers the phone.

With more than 25+ years in IT and network engineering — and deep, current experience designing cloud architecture and modern infrastructure — we bring enterprise-level knowledge to every project. Our background spans networking, cloud, cybersecurity, systems infrastructure, wireless and automation.

We can be your complete outsourced IT department, work alongside an existing IT team to add expertise and capacity, or step in for a specific project where specialized knowledge is needed. We also design and install physical security: IP video surveillance and access control.

Our roots are in the small communities of Northern California, but our reach isn’t limited to them. We support clients across the U.S. and in Germany, South Africa, India, Georgia, Ukraine, Poland and the Netherlands.

What hasn’t changed is the small-town approach: knowing our clients, understanding how their organizations actually operate, and recommending technology because it solves a real problem — not because it’s the newest thing available.

The people you’ll work with.

How we work

What you can expect from us.

Straight answers

Plain-English recommendations, written estimates and published pricing. If something isn’t worth doing, we’ll say so.

Built to last

Careful design, clean installs and documentation you keep — so your systems don’t depend on any one person’s memory.

Here for the long run

Some of our clients have been with us for more than a decade. We earn that one support call at a time.
