How we work

A named person owns your outcomes, not a ticket queue.

Every client has a dedicated Director of Client Experience who knows your business, runs regular business reviews, and is accountable when something needs escalating.

  • One point of contact for leadership; engineers your staff know by name.
  • Business reviews with metrics, risks, and the next quarter's plan.

Unified IT & Security Modernization Strengthens Operations at Everest Academy

Challenge

Wireless coverage and network stability varied across classrooms, phishing and inconsistent patching raised cybersecurity risk, surveillance and entry monitoring were limited, physical keys complicated access management, and an aging public address system lacked clarity during announcements and emergencies.

What The Isidore Group did

The Isidore Group designed one architecture for instructional technology, cybersecurity, and campus safety: Cisco Meraki firewalls, UniFi switching and wireless with dedicated VLANs, endpoint governance with patching, encryption, MFA, and role-based access, UniFi Protect cameras and UniFi Access credentialed entry with audit logging, a Visiplex public address system, and mobile device management for iPads and Chromebooks.

Result

Stable classroom connectivity improved instructional continuity, security layers strengthened protection for student and administrative systems, surveillance visibility and access logging improved administrative oversight, credentialed entry reduced the risks of physical keys, and coordinated IT governance improved board-level reporting and planning.

All case studies

As Principal of Everest Academy, student safety is always a top priority, and I'm truly grateful for the partnership of The Isidore Group.
