Quick Guide to Allowing Websites Behind a Firewall

Untrusted Websites

Untrusted websites are blocked on most firewalls to ensure that users are safe. These websites are blocked by default on most firewalls, and whitelisting a website requires special permissions within the firewall. This makes sense because you wouldn’t want to allow all websites access to your network due to security reasons.

This usually is a good thing, but it can sometimes be an inconvenience for employees that need to whitelist the website. By whitelisting a site with your firewall, you ensure that users will not receive any network errors when they visit this site and instead allows them access at all times.

List of reasons why websites are untrusted

Some companies and organizations have a firewall setup to block access to certain websites. This is done for security reasons, but can be inconvenient for employees and other people that need access to those sites.

  1. The website might contain malware and viruses, which could affect your computer if it is accessed through the company’s network.
  2. Some companies block social media sites like Facebook because employees may become distracted if they are allowed to access them during work hours.
  3. Gambling and pornography sites tend to be blocked because as users or employees may access inappropriate content. etc.

  1. Ensures that employees are safe when using company networks and cannot access potentially dangerous websites like those containing malware or viruses.
  2. Employees are able to do their work from home if they need to, since whitelisted sites will allow them full internet access at all times.
  3. Employees are not restricted from accessing social media sites like Facebook and Twitter during work hours, allowing them to communicate more easily with friends and family members. etc.
  4. Websites with bad certificates are blocked by default on most firewalls. whitelisting a website will allow it to bypass the firewall and be accessible from within your network.
