Cybersecurity & IT Support in San Bernardino County
Managed detection and response, identity protection, and security hardening for businesses across San Bernardino County, from the High Desert to the Inland Empire.
San Bernardino County is the largest county in the country by area, and the businesses spread across it, from the High Desert down through Rancho Cucamonga, Fontana, and Ontario, rarely have consistent security from one location to the next. Multi-site operations accumulate different endpoint tools, fragmented identity policies, and uneven Microsoft 365 configurations, which is exactly the kind of gap attackers look for. Sonic Systems already has field technicians servicing clients throughout the county every week, and our managed cybersecurity program brings one standardized, monitored security baseline across every office, backed by human threat hunters rather than alerts firing into a void.
Local Priorities
- Inconsistent security policies and tooling across multiple offices county-wide.
- Microsoft 365 accounts targeted by credential theft and business email compromise.
- Endpoint alerts that no one investigates, leaving real threats undetected for days.
- Compliance and cyber-insurance requirements that demand documented, provable controls.
What Is Included
- 24/7 managed EDR with human threat hunters who investigate and remediate, not just alert.
- Managed ITDR for Microsoft 365: monitoring for credential theft, impossible travel, and MFA bypass.
- Security awareness training and simulated phishing tailored to your teams.
- Firewall, identity, and access-control hardening standardized across all sites.
- Cyber-insurance alignment and security-questionnaire documentation support.
Business Outcomes
- Consistent security baselines across every San Bernardino County location.
- Lower risk of account takeover, ransomware, and business email compromise.
- A defensible posture for auditors, insurers, and enterprise clients.
- A local partner with technicians already working across the county each week.
