Email is the most widely used business tool in the world and is without borders. This great freedom and ease of use unfortunately brings its own issues and threats with email being an easy way to send viruses, unwanted messages (SPAM), leak data out of the organisation and send inappropriate content. Cygnia has solutions to thwart and manage all of the above and offers solutions from the leading email security vendors, these can either be on-premise or cloud solutions.
Types of Email Security “On Premise” or “In the Cloud”?
Email security comes in two forms “On Premise” or “In the Cloud”. On premise solutions reside on the organisations network, in the cloud solutions are done out on the internet by managed services providers.
On premise solutions generally tend to be more granular than in the cloud offerings, although the organisation has the overheads of power, updating the system, providing redundancy should an appliance/ server fail and updating the hardware.
Email security checks a number of the parameters of an email as it enters in to the organisation typically this looks against the organisations email policy. The parameters are typically, if the email is considered as SPAM, the security of the email for viruses and malware and the content of the email if it has explicit words or contains confidential information. If an email does breach the policy there are a number of remediations that can be performed, these include quarantining the email, deleting it, allowing it through but reporting the event, etc.
Data Leakage Prevention
Many organisations are looking at Data Leakage Prevention (DLP) and the controls they can put in to place to manage data loss from the organisation. Cygnia’s range of email security solutions are extremely configurable and can help as part of a wider DLP strategy. With policies that go down to user level managers and administrators can control who sends and receives what and the checks and balances that are put in place to prevent information leaving the business.
Email encryption provides secure transport of emails from one recipient to another. The types of encryption can vary from PGP, SMime, TLS and Web Portal Technologies as do the transport methods. PGP emails are sent from one gateway to the other whereas web portals stay on the senders network and the recipient uses an SSL session to view the email like a secure webmail session. Clearswift offers PGP, SMime, TLS and Web Portal encryption, Mimecast offers TLS encryption.
