Built to Protect Main Street.
We believe small businesses deserve the exact same level of cybersecurity protection as the Fortune 500, without the complexity or enterprise price tag.
Built by Someone Who Has Been on Your Side for 17 Years.
I know what it takes to run a business because I have done it more than once. From wireless retail to the financial industry to construction, I have sat at the owner's desk, made payroll, managed people, and carried the weight that comes with building something. That experience shapes everything about how I approach protecting yours.
In 2009, I founded PC Office Technology as an IT support company. Over the years it grew into Red Door Technologies, and I brought on a trusted partner to help us scale. For 17 years, I have worked inside Chicago small businesses, law firms, accounting practices, contractors, property management companies, and healthcare practices, watching what it actually takes to keep them running.
I watched the threats grow from a virus on one computer to AI-powered attacks targeting thousands of small businesses at once. Last year, I wrote Operation Cyberguard because I knew what SMBs needed to survive the next decade. That work led to a clear decision: Red Door Shield is my answer to that problem. It is what I designed specifically for business owners who need real protection without the complexity, the confusion, or the cost that comes with enterprise security.
When you call, you get me. I will walk you through everything, get you set up, and make sure you understand exactly where you stand.
Red Door does not just mean protection for my clients. For me, the Red Door has always represented being covered, being safe, being cared for. That is what I want for every business owner I work with.
