Internet traffic is mainly composed of unwanted traffic and we don't want that to get into our network. We pay our service provider a lot of money for bandwidth and we don't want to pay for someone else abusing our network resources. This is what will happen if you are to use a traditional spam control technique.
With SpamCheetah, you are guaranteed to get close to 100% protection for your e-mail resources as well as protect your network and server infrastructure. Whereas with traditional content scanning spam fighting techniques, the damage is stopped at the last minute: before the spam lands up in the user's mailbox. Moreover content scanning leads to the scary prospect of false positives. You MAY lose important e-mail if you use content scanning. With SpamCheetah we guarantee zero false positives.
E-mails form a very important aspect of modern corporate infrastructure and we cannot afford to take spam control lightly. SpamCheetah does not stop just spam but also viruses, Trojans and other malwares including phishing attacks since they all propagate in the same fashion.
Guaranteeing 100% uptime for your network services has always been a problem. No matter how much time, money and effort we spend on ensuring that the hardware and software infrastructure does not suffer a failure, Murphys' law strikes once in a while and we cut a sorry figure.
ravanan aims to tackle this problem in a very smart manner. It not only ensures that the services are available at all times but also that the backup is no worse than the master. ravanan will not lead to any service degradation whilst the servers are up and also give identical performance if your backup server is synchronized with the master server.
Since ravanan works at layer III of TCP/IP for load balancing and fail-over and layer VII for service redirection, you get the best of both worlds. You get very fast response times for fail-over and the flexibility of HTTP session persistence.
