Websense offers several email security solutions to address modern threats. Their solutions leverage the Websense ThreatSeeker Intelligence Cloud and Advanced Classification Engine (ACE) to detect known and unknown malware, spam, and targeted attacks. Key capabilities include gateway threat analysis, point-of-click URL sandboxing, behavioral file sandboxing, and built-in data loss prevention. Websense solutions can be deployed in the cloud, on-premises with appliances, or in a hybrid model.

1. WEBSENSE EMAIL SECURITY
SOLUTIONS OVERVIEW

2. Websense Email Security Solutions Overview
Challenge
The nature of email threats has changed over the past few years. Gone are the days when email security, better
known as anti-spam, was primarily tasked with blocking based on volume and scanning for email-borne viruses. The
signature-based techniques used in early solutions, while still a viable part of a multi-layered strategy, are simply not
capable of protecting organizations from the highly targeted, blended attacks of today. In February 2012 IDC stated,
“Signature-based tools are only effective against 30–50% of current security threats.”
Solution
Read the cybercrime blogs and it’s evident that email is still a major attack vector. But read further and you’ll find
that a large percentage of the attacks are actually perpetrated via the web. The takeaway is email facilitates the
attack and web actually performs the actions. A modern security approach therefore requires both web and email
channels be evaluated with a strong cross-pollination of information between the two.
Websense® email security solutions are built on our core TRITON® technologies:
•
Gateway Threat Analysis leverages security intelligence from the Websense ThreatSeeker® Intelligence Cloud
and Websense ACE (Advanced Classification Engine) — collecting data from more than 900 million endpoints
and analyzing up to 5 billion requests per day — to thwart advanced malware, spam, and blended threats.
•
Point-of-Click Threat Analysis sandboxes suspicious links embedded in emails at the recipient’s point-of-click.
•
Behavioral File Sandboxing analyzes suspicious files attached to email.
•
Built-in Data Loss Prevention (DLP) monitors and prevents sensitive data such as product roadmaps or
customers’ personally identifiable information (PII) from leaving the corporate network via email.
