What Chesterfield businesses get from one team
Managed IT, cybersecurity and business phone systems, run by one local team.
Managed IT Support
Unlimited remote and onsite support, proactive monitoring of devices and servers, patch management, vendor coordination, onboarding and offboarding, and documentation of every managed system. Urgent issues get a response outside the 8-to-5 window.
Co-Managed IT
If you already have IT staff, we add capacity, coverage and specialized expertise around them, so vacations, after-hours incidents and projects outside their skill set stop becoming your problem.
Cybersecurity and 24/7 Monitoring
Layered defenses across devices, accounts, email and web activity, watched around the clock by a U.S.-based Security Operations Center.
Backup and Recovery That Is Tested
Workstations, servers and Microsoft 365 backed up, verified and restore-tested, so ransomware or a hardware failure does not become a crisis.
Business Phone Systems
Cloud phone systems with Total Voice, or support for existing Avaya IP Office and Aura systems.
Cybersecurity Risk Assessment
A Cybersecurity Risk Assessment finds the gaps and shows what to fix first.
