“Most owners have gotten used to bad IT. I'd like to ruin that for you.”

Billy DunnFounder, BDunn & Company, since 1989

Keep the day running.
Make the work better.

Those are parts of the same relationship. The better we know your business, the more useful we can be.

Dependable IT.

Computers, networks, email, phones, backups and security. We make the systems work together, keep them maintained, and help your people when they need us.

  • A staffed security operations center watches around the clock.
  • Backups are checked daily and test-restored on a schedule.
  • We work through problems with your software and equipment vendors.

Your staff shouldn’t have to referee the vendors to get an answer.

How we look after your IT

A more productive business.

We look for the work that consumes time, hides mistakes, or keeps getting put off. Then we use the right mix of experience, software and AI to improve it.

Years of documents. A usable chronology.

For a law firm, we built a workflow that put records in order and linked the facts to their original documents and pages.

The first draft went from about six hours to 35 minutes, ready for attorney review.

37 years

In business: Billy started it in 1989. The same family runs it today.

25+ years

Client tenure: Many clients have stayed more than 25 years. Almost all have stayed more than 10.

24/7

Security watch: Your business closes. The watching doesn’t.

Yours

What you own: Your domains, licenses, documentation, and the code we write for you.

What a quiet night looks like

6:00 PM

You go home.

The lights go off. The watching doesn’t. A full security operations center (SOC) takes the night shift on your systems, 24/7/365.

Your office goes dark at 6. We don’t.

8:00 AM

You walk in. Nothing happened.

When you do need us, call (817) 265-5000 and we pick up.

That was one night. Give Billy 15 minutes and he’ll tell you what we’d be watching at your place.

  2. 11:00 PM Handled before you knew

    A drive starts to fail.

    We catch it early, your data stays safe, and a replacement is on the way.

  3. 12:40 AM Handled before you knew

    A runaway log starts filling the server’s disk.

    We clear it out, so there’s room again before the morning rush.

  4. 3:00 AM

    Backups, checked.

    Every backup is checked daily for success, and test-restored on a schedule: real files, or a copy of the server booted up.

  5. 4:30 AM

    Patches, on a schedule.

    Windows, macOS and the third-party apps, not just Windows Update.
