An IT Partner Down the Road, Not Across the Country
Buzz has been protecting Southern California businesses since 2011. Here is what clients tell us makes the difference.
Cybersecurity-First IT
Protection is built into every service from the first day, never bolted on after an incident. One team runs your technology base and your defenses side by side.
Fast, Human Response
When something slips, a real person reaches out quickly. We move fast, speak plainly, and finish the fix instead of closing the ticket early.
Founder-Led Trust
Edward Baker leads Buzz personally. Clients reach the people in charge rather than a rotating bench of junior techs, and always know who answers for their account.
24/7 Monitoring
Your systems stay under watch at every hour. Threats get handled the moment they surface, not after someone spots the problem the next morning.
Transparent Pricing
We never ask you to disclose your revenue, and no paid assessment stands between you and a quote. You get clear numbers and a plain rundown of what they cover before anything is signed.
Free Assessments
Qualifying businesses get a no-charge security audit. You walk away with a plain-language read on where you are exposed and practical recommendations, with no strings attached.
Industries
IT and Cybersecurity Built Around Your Industry
Buzz works across a wide range of sectors and brings real experience in each one, rather than the same template applied to every client.
Healthcare & Medical Practices
HIPAA work, device upkeep, and steady uptime for the systems clinics depend on every day.
Financial Services & Insurance
FINRA readiness, protected client records, and breach defense for regulated firms.
Legal Offices & Law Firms
Locked-down case files, tight access controls, and client confidentiality that holds up.
Biotech & Life Sciences
Research data protection, validated systems, and compliant infrastructure for science teams.
Professional Services
Protected cloud apps, quick helpdesk help, and IT that keeps busy advisory teams moving.
Charter Schools & Education
Safeguards for student records, E-rate help, and managed IT that respects the budget.

FAQs
Common Questions
Quick answers to what businesses ask us before they reach out.
What does Buzz Cybersecurity actually do?
Buzz runs your technology and your security as one job. That covers everyday IT management, helpdesk, patching, and planning, plus the protective side: threat monitoring, detection and response, backups, cloud security, and ransomware defense. Most clients hand us the whole thing. Some keep an internal IT person and use us for the parts that need depth.
Where does Buzz work?
We have offices in Irvine and Corona and support businesses across Orange County, Riverside County, San Bernardino County, Los Angeles, and San Diego. Day-to-day work happens remotely. When a job needs hands on the equipment, an engineer drives out.
How fast does Buzz respond when something breaks?
Urgent items go to the front of the queue. Because your systems are monitored every hour of the day, a good share of issues are caught and settled before anyone on your staff notices. When you do send a request, a person answers it, not a chatbot and not a next-day ticket.
Can Buzz work alongside our in-house IT team?
Yes. Co-managed IT is a large part of what we do. Your internal team keeps the day-to-day and the projects they know best, and we take monitoring, after-hours cover, security operations, and the heavier infrastructure work. It adds bench strength without another salary.
Which compliance frameworks can Buzz help with?
We support businesses working toward HIPAA, FINRA, PCI-DSS, NIST, and CMMC. We review where you stand today, point out the gaps in plain language, and help put the controls and documentation in place so an audit is not a scramble.
What is included in the free assessment?
It is a hands-on review of how your IT runs right now: the network, the devices on it, how access is granted, the software in use, and the weak points already present. You get a written rundown in plain English, what each finding means for your operation, and what we suggest doing next. No cost and no obligation.
