Email Filtering

Email Filtering

Email content filtering is now an essential element of perimeter security. It allows corporations to enforce their email acceptable use policy (AUP) at the gateway; providing protection against cloud, endpoint, gateway, viruses, spam, phishing, dangerous file types, and inappropriate language while educating users on appropriate email usage.

Almost all email AUP’s contains a clause that few email content filtering applications can enforce. This clause expressly states that the email system is not to be used for the distribution of pornographic or Not Safe For Work (NSFW) images. Without image and video recognition technology this type of content can travel in and out of corporate email systems hidden within the mass of legitimate business communications.

Pornographic and NSFW visual content in the workplace can degrade company culture, damage brand reputation and contribute to the creation of a hostile working environment. In most countries, employers have a duty to protect their employees from sexual harassment. They can be held vicariously liable for the actions of an employee unless they can demonstrate they have taken all reasonable steps to prevent it from taking place.

“The proliferation of pornography and demeaning comments, if sufficiently continuous and pervasive may be found to create a hostile working environment.”
