“We were positively surprised by their high level of support! That’s why we changed from Spamhaus to Abusix.”

Thomas L. – System Engineer, Switzerland

“Trialing Abusix’s Blocklists was pretty straightforward. The configuration of my mail servers took me a couple of minutes and I immediately benefited from a reduction in system load – Thanks guys! ”

Peter D. – Head of Security, Germany

“The deciding factor to go with Abusix was the amount of positive detection, which was significantly better than the competitors’ solutions. As a decisive test, we have created a few fake, very fresh domains and send spam to ourselves and Abusix Mail Intelligence was the quickest to pick those up.”

Mateusz C. – CSM/IT Manager, Norway

“rspamd plus Abusix is as good as it gets.”
