Following the evaluation of different email systems, our customer decided upon BULPROS’s modular and rule based solution iQ.Suite for Microsoft Exchange. The significant advantage of the solution was that it is server based. This ensures that incoming emails are first decrypted, then tested for viruses and content, and afterwards archived and delivered without user intervention. The process is reversed for outgoing emails: first, testing for viruses and content on the server, then archiving and encoding. In this way, all important security checks could be accomplished with little effort even before the email left the company or alternatively reached the receiver.
Another reason for the customer to adopt iQ.Suite was the company-wide scalability of the solution and the flexible upgrading all the way to the realization of a continuous and integrated Email Lifecycle Management (ELM). In addition to encryption and anti-spam, this encompasses email classification and compliance as well as email archiving.
The paths of the emails were short due to the integrated modules. Moreover, the solution was easily integrated into existing IT structures with excellent performance and remained stable even with extremely heavy email use.
The IT and network administrator introduced the email encryption to the company at the request of domestic and international sales partners. Certain information such as calculations or invoices had to be accessible only to the recipient of the message and be protected from viewing. This requirement was quickly fulfilled using the module “iQ.Suite Crypt” for server-based en/decryption. The company-wide encryption guidelines could be centrally and flexibly configured.
Now only a key needs to be stored centrally on the server for each encryption process used. In this way, the receiver of the email easily receives the public key and the communication partners can exchange encrypted emails including attachments. The emails are signed for increased security ensuring authenticity and integrity of the email.
To test encrypted emails for viruses, emails are first decrypted using iQ.Suite on the server and then analyzed by Malware. The first scan for viruses exposes any possible false keys. Only then, the email is decrypted and scanned for viruses a second time ensuring “clean” emails in the in-box.
Most convincing was the anti-spam module “iQ.Suite Wall” with its consistent management console for the simple processing of unwanted messages, the unerring content analysis of emails and the message summary function. In addition, the users receive regular messages regarding newly filtered emails located in “suspected spam”, which the user can then forward into his/her inbox. To minimize the amount of administration, the administrator can allocate incoming emails to whitelists and blacklists containing sender addresses that are allowed and not allowed respectively. Thus, e.g. desired and not desired newsletters can be easily differentiated.
The effect of the spam filter can be significantly increased through content analysis of emails. The CORE technology (Content Recognition Engine) integrated in “iQ.Suite Wall” analyses both the subject line and the content of the email including the attachments according to company guidelines reaching spam recognition rates of over 98 percent. False positives are almost negligible using this email filter.
