Re: Securing email by inhibiting urls

["Ilias - " <ilias_pavilion () live nl>]

Hi,

I'm using MailMarshal with blended threat module, which also protect against zero day exploit URL's.

Take a look at the PDF : 
http://www.m86security.com/documents/pdfs/datasheets/email_security/DS_Blended_Threats_Module.pdf

If you want some further information about this solution and how you can use this.. Send me an (direct) message.

Best regards,

A company I work for has been having great difficulty in securing against email attacks.  So far we have disabled 
access to webmail, implemented  rules and processes to block freemail services like hotmail etc until the sender 
registers the address and of course a spam filter (BrightMail).  Attachment filtering is pretty strict as well.
 
The threat that presents the biggest challenge is url links in emails.  The common method of attack is an email from 
somedomain.com <http://somedomain.com>  where they change one character or otherwise make the address look valid (ie: 
joe () s0medomain com <mailto:joe () s0medomain com>  or j0e () somedomain com <mailto:j0e () somedomain com>  etc).
 
I was looking for a way to spot and block hyperlinks but it looks like the only option I have is to filter on these and 
send them to a spam bin.  I'd rather yank the offending hyperlink and replace it with a message of some sort.  
Unfortunately BrightMail doesn't offer that capability.
 
Any products that do this or ideas on a solution?
 
Thanks
