·	Older operating systems, even when still supported by the creating company, often have technical limitations that make it impossible to properly protect our customers using new and advanced ZoneAlarm technology.

·	When the creating company stops fixing the new “holes” discovered by hackers in its operating system, customers are much more vulnerable to attack.

·

ZoneAlarm strongly encourages its customers to adhere to a “best practices” approach to security, where each best practice that’s upheld makes the customer much less likely to fall victim to attack; and every best practice ignored makes the customer much more vulnerable. Keeping software, including the operating system, up-to-date with the latest security patches is an essential best practice.
