WatchGuard has released an update to its XCS (extensible content security) line of email and web content security appliances.
To offer new spam blocking and encryption capabilities, it said that the new WatchGuard XCS add-in for Outlook allows end-users to mark any delivered messages that bypass the XCS spam filters as either ‘spam' or 'not spam'.
It said that this way, end-users gain the ability to report false positives where legitimate messages were marked as spam, as well as false negatives, where a good message was tagged mistakenly as spam. In addition, the tool adds senders to the end-user's personal ‘trusted' or 'blocked' senders list giving them more control over their messages.
WatchGuard has also strengthened its XCS line with SecureMail Email Encryption, which allows end-users to encrypt sensitive outbound messages directly from the WatchGuard XCS appliance without the need for a local encryption server or additional desktop software.
According to the company, messages are secure until they are delivered and unencrypted via a simple authentication process by the recipient. It said that this feature can also be customised as a branded service for organisations wishing to promote their brand as part of their commitment to highly secure email communications.
Tim Helming, director of product management at WatchGuard, said: “Email continues to be a significant threat vector for businesses around the world. These latest enhancements to WatchGuard's XCS security appliances provide for even better spam blocking efficacy and the new encryption features give peace of mind to businesses that want to ensure that their sensitive data is handled securely.”
