When we've needed to contact support, the response has always been very precise. The Altospam teams know their solution inside out. The benefits? A non-intrusive solution, a comfort solution for teams who don't have the time. Time-saving for users. The ability to consult statistics on the interface and, above all, a PRA service is included for emails.

The quality of spam filtering is very good, the number of false positives is very low, and I'd like to emphasize the solution's good value for money.


Choosing ALTOSPAM's outsourced software enables us to efficiently clean up our mailboxes on a daily basis, and to reduce our company's network traffic.


The reliability and availability of the service, combined with a relevant price positioning, make this anti-spam solution particularly well-suited to the needs of VSEs, SMEs and large accounts.


We're very satisfied with the quality of ALTOSPAM's filtering, which stops spam before it clogs up our computer network unnecessarily.


Since we've been using ALTOSPAM, the number of spam messages in our mailboxes has dropped considerably, we no longer receive phishing or adverts, and our internal network is really unclogged.


I chose ALTOSPAM because, in terms of anti-spam effectiveness, it's the best! The ALTOSPAM solution is really perfect, and what's more, if I need any information, all I have to do is contact support and I'm efficiently informed!
