We recommend...
- BlissRADIUS™
- For Internet Service Providers, small or medium business with requirements for RADIUS authentication and accounting of large number of users. Or medium number of them. Or not so many. Or only if it means keeping under control those few annoying neighbors or friends you share your link with - BlissRADIUS™ will do the job!
- BlissRADIUS Embedded™
- If you need RADIUS but already have client provisioning setup like WHMCS or Blesta or your own home made solution you are proud of, and you don't want to migrate to anything else - then try BlissRADIUS Embedded. Just plug it in and it will work out of the box!
- BackupDude™
- Home or business users that have those folders with special stuff you want to keep safe! But not on the same computer, because we all now that local backups are no backups!
