John was an important person. He handled a lot of things that were essential to the working of the company. He was smart and successful. One day, he visited an illegal torrent website from his company laptop to download the latest Spiderman movie. He got the movie but a sneaky ransomware encrypted all his important files.
What is website whitelisting?
Website whitelisting is a regulation that system administrators use to block user access to all websites except for the required ones. The admin can create a list of safe and approved websites that the user requires. Once the website whitelisting policy is in effect, the end-user can only access the pre-approved websites.
Hexnode UEM supports web content filtering – website whitelisting and blacklisting – in Android, iOS and macOS devices.

Website whitelisting in iOS
Whitelisting websites is a simple process if the iOS devices are enrolled in Hexnode. This feature is only available for supervised iOS devices. On configuring the website whitelist policy, private browsing would be disabled for the users. The users would also not be able to clear the browsing history and website data in Safari after the website whitelisting policy is in effect.
Website whitelisting in Android
The Hexnode admin can specify the website URLs to be whitelisted in a policy. You can also choose whether to allow Google Play Store or not. The Android devices should be enrolled in Hexnode. Another point to be noted is that website whitelisting and web content filtering only works on Samsung Knox devices with Customization SDK of 2.6 or higher.
Website whitelisting in macOS
On whitelisting the websites in macOS, the users would not be able to access any other websites from the Safari browser. If you want to restrict the users from accessing the websites in any browser, you should use the app blacklisting/whitelisting feature to restrict all other browsers on the device.
Whitelisting vs Blacklisting
Whitelisting and blacklisting are like two sides of the same coin. While whitelisting involves allowing certain websites and blocking all others, blacklisting follows a slightly different approach. Instead of creating a whitelist, the admins create a blacklist. This list has all the website URLs that are to be blacklisted, I.e., the websites that the user wouldn’t be allowed access to. Simply put, website blacklisting is blocking certain website URLs and allowing access to all others.
Blacklisting the websites could be enough in some cases. However, more often than not, it is not enough. There are new websites popping up by the second and the blacklist would have to be regularly updated. It would be a tedious job for the admin – and not a very productive one. In contrast, whitelisting the websites give the attackers lesser legroom to work with.
Hexnode’s UEM solution allows the admins to configure both blacklisting and whitelisting the websites. Go for the option that suits your use-case best.
Benefits of whitelisting
Whitelisting is a popular security tactic deployed by admins. There are some really good reasons for its popularity.
- Secure browsing experience: Just like John, employees are tempted to browse things that do not exactly fall under the work domain. It is hard to keep track of everything that the employees do. It would also not be a healthy work environment if you need to continually monitor everything that your employee does. Whitelisting the websites that you can visit resolves this problem to a great extent. Since the employees are restricted to the pre-approved secure websites, the security risk is highly reduced. All you need to make sure is that there aren’t any unsecure websites in the whitelist!
- Reduced data expenses: Who doesn’t love office Wi-Fi? It is fast and it is free. For large enterprises, the data costs would not probably be something to worry about. However, the increased data expenses could be a major setback for small and medium-sized businesses. Whitelisting just the required websites would prevent the users from using it for their own purposes. Now, John definitely wouldn’t download movies or watch football on the company network.
- Increased productivity: While working, it is perfectly normal to be distracted for a minute or two by those perfectly targeted advertisements or a random Google search that leads to more. However, these minutes turn into hours and before you know it, the whole day has gone by without any work done. Website whitelisting is one of the ways that you can prevent users from wasting their time unintentionally.
A small step into a secure future
While website whitelisting alone would not ensure a cyber-secure work environment, it is definitely one of the steps that can help. There are also other uses of website whitelisting such as for web-based kiosks. While there are multiple software and tools in the market that would let you do website whitelisting, it is better to go for a UEM solution like Hexnode in the long run. It would help you to manage, monitor and secure all the work devices across different platforms in a highly scalable manner.
