CSN utilizes several defenses to protect students, faculty, and professional staff against spam. There are several spam-fighting organizations which maintain remote blocking lists. Spam that is not blocked based on the source then goes through the Office 365 spam filter system, which compares contents of emails to possible spam indicators.


  • Enhanced matching against blocking lists
  • Blocking and filtering settings updated daily
  • 90% success rate for filtering spam that bypasses blockers
