Pinnacol Assurance customer success story

The challenge

After evaluating their data center’s infrastructure, maintenance and operating costs, and the limited ability for the facility to support redundant power without significant cost and effort, Pinnacol’s Informational Services group found the data center to be outdated and inefficient.

The results

Pinnacol increased security, redundancy, power, connectivity and reliability. The colocation data center scaled to meet shifting needs, even post-contract signature. Greater energy efficiency also lead to greater cost efficiency than staying in-house.

In their words

“We aren't their largest client but we're treated like we are." "They go the extra mile to make sure we get exactly what we need when we need it.”
