Most IT companies give you a help desk ticket. We give you our cell phone number. BDunn & Company delivers enterprise-grade IT with the personal touch of a trusted partner — not a vendor.
Think about electricity. You flip the switch and the lights come on. You don't think about it — it just works. That's the standard BDunn & Company holds itself to for your technology. We set everything up right the first time, and then it runs. Reliably. Predictably.
Billy Dunn has been managing IT for small and mid-size businesses in the Dallas–Fort Worth area since 1989 — longer than most IT companies have existed. We've never needed advertising because our work speaks for itself. Every single client relationship we have started with a referral from someone who trusted us enough to share our name.
When we set up your environment, we do it once, we do it right, and we stay with you. No call centers. No tickets. No runaround. Just direct, expert help when you need it.
From your daily email to your network security, we handle every layer of your technology infrastructure — so you can focus on running your business.
Proactive monitoring, maintenance, and support for your entire technology stack. We watch your systems 24/7 so issues are resolved before they become problems you feel.
Multi-layer endpoint protection, email security, network monitoring, and security awareness. We deploy and manage ESET endpoint security and maintain a hardened perimeter for your business.
AI-powered autonomous agents represent a new attack surface most businesses aren't prepared for. We evaluate your exposure and implement policies to protect against AI-driven threats before they reach you.
Our preferred productivity platform. We deploy, configure, and manage Gmail, Drive, Meet, and the full Workspace suite — including security hardening, admin console management, and ongoing user support.
Full Microsoft 365 deployment and management including Exchange Online, Teams, SharePoint, and Azure Active Directory. We support clients who depend on Microsoft's ecosystem and keep it running cleanly.
We deploy and support Yeastar IP PBX systems with Yealink desk phones — professional, reliable VoIP for small businesses. Feature-rich call routing, voicemail, auto-attendant, and mobile apps included.
Platforms We Deploy & Support
The IT industry has trained businesses to accept slow response times, anonymous help desks, and vendor-of-the-month relationships. We've never operated that way — and we never will.
When you have a problem, you call us directly. No ticket numbers. No queues. No automated phone trees. You get a real person who knows your business — because we've built a relationship with you.
We set your environment up right from the start. The right hardware, the right software, configured the right way. When everything is done correctly, ongoing IT work drops to 3–5 hours per week. That's our goal for every client.
We haven't run an advertisement in over 25 years. Every client came to us because another client recommended us. That's the only endorsement that matters — and it tells you everything about how we operate.
We've built deep expertise serving specific industries in the Dallas–Fort Worth area. We understand the compliance pressures, the workflows, and the risks unique to your field.
Secure, compliant IT environments for financial advisors, CPAs, bookkeepers, and accounting firms. We understand the sensitivity of financial data and build environments that protect it.
HIPAA-aware technology for medical practices, dental offices, and healthcare providers. We configure and manage systems that support protected health information while keeping your staff productive.
Law firms demand reliable, confidential, and always-available IT. We support attorneys and legal professionals with secure document workflows, reliable communication systems, and bullet-proof uptime.
Rugged IT solutions for industries that work hard. We support contractors, manufacturers, and energy companies with practical, dependable technology that keeps pace with demanding operational environments.
Artificial intelligence is transforming the attack surface. Agentic AI systems — autonomous software agents that browse, communicate, and act on their own — are already being weaponized by bad actors to probe, phish, and breach business networks at scale and speed that humans can't match.
Most small businesses have no defense posture for this at all. We do. We stay ahead of emerging threats so you don't have to think about them.
We've called the Dallas–Fort Worth area home for over three decades. As part of our commitment to this community, we donate retired business computers — still capable machines — to Mission Arlington, a local nonprofit serving thousands of families in need.
We don't do hard sells or generic demos. Tell us a bit about your business and what's not working the way it should. We'll have a straightforward conversation and tell you honestly whether we're the right fit.
