Powerful Fingerprints

Cloudmark employs five fingerprints which are used in all Cloudmark products. These fingerprints have been developed by Cloudmark Research over the past five years and are a part of Cloudmark's core intellectual property which:

  • Provide a highly effective defense against spam and phishing messages.
  • Have been optimized to target the techniques that spammers use.
  • Require no intervention, freeing up administrators from the manual and error-prone management of lists and rules.
