Websense Security Firm estimates that 70% of all Internet connected PC’s are vulnerable to a Zero-Day exploit affecting Microsoft Internet Explorer

A zero-day vulnerability is one that is discovered as already being exploited in the wild. Typically, vulnerabilities are discovered by security researchers who only share the details with the manufacturer. The manufacturer then has time (X amount of days) to develop a patch before hackers discover and exploit the vulnerability. With a zero-day vulnerability, the manufacturer has had, “zero-days” (0 amount of days) to implement a patch.

When the patch hasn’t been released yet what do you do?
In this case, you can use an alternate browser like Chrome or Firefox, but you are counting on everyone at the office to remember to do this.

You can also add Internet Content Filtering for an automatic layer of defense. By filtering out access to suspicious sites or only allowing access to approved websites you can increase productivity and security.
