ORF ♥ administrator

No false positives

Never miss an important email again. ORF ships with multiple dedicated tools against false positives.

Proven performance

Deployed at 11,000 organizations in 112 countries, ORF filters thousands of emails every second, 24 hours a day.

Being a network administrator for several cities and businesses, I was testing many different products to find the right one. I understood exactly what I wanted a product to do but nobody offered just the right combination of spam checking tests. That is until I stumbled across Vamsoft in a forum on the web. Everywhere I read about ORF, the users were delighted. Now, so am I.
