Our success is measured not by our standards, but by those of our clients.
That’s the CrossRealms difference.
How we Transformed the Ravina Festival Experience with the Aruba WiFi Project

CrossRealms implemented a breakthrough system at Ravinia Festival to ensure wifi access for their 15,000 guests and staff all-throughout the park. Now, Ravinia has one of the strongest crowd-focused wireless connections in the entire country. See how we got there…

“In the process, I got to know the ‘CrossRealms way of thinking’ and just really liked it. Their dedication is to the quality of the solution, not to sell a product. So, I never have to worry about their motivation. They’re always looking after my best interests and their subject-matter expertise has been a tremendous load off my mind.”

PAWS Chicago Overhauls IT Infrastructure and More: Testimonial for IT Services Firm CrossRealms
PAWS Chicago Co-Founder Alexis Fasseas and others discuss the comprehensive managed IT services and solutions that CrossRealms Inc. provides to the Chicago-based, no-kill animal shelter. PAWS was looking for guidance on IT and they needed to update their infrastructure and applications. They also sought to obtain more responsive IT support, reduce downtime, and achieve cost savings.

What we did:

  • Reduced the number of servers at each PAWS location, moving 10 servers to our CoreSite data center
  • Upgraded circuits to Firstcom
  • Replaced old firewalls at four locations with new, more powerful Palo Alto Networks firewalls (and reconfigured them)
  • Upgraded wireless at three locations
  • Re-cabled one location for expansion
  • Switched from Microsoft Exchange to Office 365
  • Installed devices for electronic display screens
  • Implemented 3CX Phone System at one office
  • Web hosting
