Some content filtering systems have more limited functions and provide a blanket ban across entire networks. But other more comprehensive content filtering firewalls are able to give you more granular control over what types of content are allowed to pass through. This means you are effectively able to block content based on several factors and even across different levels of employee hierarchies. All in all, content filtering is crucial and an extremely effective strategy for organizations to deploy. However, although content filtering firewalls need to be a key component of your cyber security strategy, it should be complemented. Organizations can combine content filtering with other security methods, such as two-factor authentication, to protect against untrusted networks and cybercriminals.
