Ransomware and payment fraud now target companies with 10 employees as readily as companies with 10,000. Quantum designs security in layers: identity, endpoint, email, network and backup — each one monitored, each one tested. The result is a business that can pass a cyber-insurance questionnaire and sleep at night.

Frequently asked questions
Do small businesses in Riverside and San Bernardino County really get attacked?
Yes. Attackers automate their targeting, and smaller companies are attractive because defenses are thinner. Most incidents we see start with a phishing email or a reused password, not a sophisticated exploit.
Will you help with our cyber-insurance application?
Yes. We map your controls to the carrier's questionnaire, close the gaps (usually MFA, EDR and tested backups) and provide documentation the underwriter accepts.
Is cybersecurity included in managed IT?
A security baseline is included in every managed plan. Advanced services such as 24/7 SOC monitoring, compliance programs and penetration testing are scoped separately.
