Providing the highest level of security and privacy for our members' electronic information is a responsibility that Spokane Teachers Credit Union takes very seriously. That's one reason why we chose dark fiber from Columbia Fiber Solutions - to ensure the highest level of security for our members online, telephone or traditional, in-branch financial transactions. Dark fiber has also provided STCU with significant time savings in our data and information transmissions because of the speeds associated with high bandwidth networks, allowing us to improve our customer service on many levels.
