Case Study: SureWest Communications boosts outbound spam filtering and cuts CPU load with Cloudmark Authority

SureWest Communications cuts scan times to under 1 second with Cloudmark

SureWest Communications, an internet service provider, faced a challenge with growing outbound spam. This issue was increasing their resource consumption and putting them at risk of being blacklisted by other ISPs. To address this, SureWest sought a solution from Cloudmark that could extend the capabilities of their existing SpamAssassin email platform.

Cloudmark implemented its Cloudmark Authority for SpamAssassin solution. This provided immediate results, including a 50% reduction in CPU load and the ability to process 50% more messages per hour. The solution also increased filtering accuracy with zero false positives and allowed SureWest to reduce its physical hardware by 25% initially, with plans to cut it by 60% in the medium term. Cloudmark's solution helped SureWest proactively block outbound spam and significantly reduce administrative costs.
