About Us

CIS is a locally owned and operated internet service provider based in Missoula, Montana. We serve Missoula and the surrounding Five Valleys region, providing fast, dependable internet with hands-on support from a local team.
Since our founding nearly three decades ago, we’ve earned a strong reputation for reliable service and a commitment to our community.
In March 2024, CIS entered a new chapter with the transition of ownership to Max Moss. Our team has since focused on upgrading infrastructure and adopting modern technology to build a stronger, more resilient network.
We provide 24/7 network monitoring and on-call technical response to keep service interruptions to a minimum. Our support team is made up of experienced technicians who take a direct, solution-focused approach — prioritizing clear communication and efficient problem-solving.
