Since 1987 we have been helping clients procure, install, secure and support their computer networks. 

 

WORLD CLASS NETWORK SECURITY FOR SMBs
We recommend that organizations with less than 500 users deploy a combination of Fortinet firewalls together with Sophos endpoint protection software.  These systems have overlapping features which can protect against threats targeting specific security vendors.  In addition, each system offers best-in-breed overlapping protection from the scourge of cryptoviruses and ransomware.  Dual-factor authentication for remote users is also strongly recommended.

HOW WE CAN HELP
Let us help secure your network with these products and services:

  • Firewalls and advanced security solutions from Fortinet

  • SIEM systems, secure wireless and SD-WAN systems from Fortinet.

  • Server and endpoint protetion systems from Sophos.

  • Disaster  Recovery as a Service (DRAAS) systems from Unitrends.

  • Penetration testing and security assessments.

  • Post-incident security analysis and 24 x 7 recovery services.

  • End-user Phishing tests.

Managed Services: The Modern Way to Manage Computer Networks


In this age of crypto-viruses and ransomware, it is critical that organizations manage their networks in a secure manner. For smaller organizations without an-house IT staff, managed services are the best way to accomplish this. Organizations that can benefit from fixed-price monthly support plans include government entities, manufacturers, medical and dental practices and service businesses. 


Our CompleteCARE managed services program is a fixed-price support program designed to cover all of your computer network maintenance needs. Features include: 

  • Unlimited remote, telephone and on-site support.

  • Daily monitoring of PCs, server, firewalls, and network components.

  • Regularly scheduled and as-needed onsite visits.

  • Quarterly file recovery tests to verify that data backup systems are working.

  • Yearly complete server and VM recovery tests to our hardware.

  • Easy to understand fixed-price monthly billing based on the number of servers plus the number of PCs/Tablets/Laptops/Kiosks that are installed.

  • License management and renewal support.

  • Priority access to Sr. IT engineers and executives.

  • Hardware diagnostics and basic repairs.

  • Support for Microsoft Windows Server, MS-Windows, MS-Exchange, Hyper-V, VMware, Linux (most versions), FortiOS (Fortinet's OS) and Cisco IOS.

  • Local support, management and ownership.

  • 10% labor discount on projects outside the scope of managed services.
