The issue with the vast majority of VPN's is that because they block your ISP from seeing what you are looking at on the internet, they also bypass any filters you may have switched on, such as parental controls or other security features. Basically, if your ISP cannot determine where you are on the internet, how can it block the more harmful aspects of the web?
A solution to this would be for the VPN's themselves to have their own established filters, but do they? We explored VPN’s across a broad scale trying to determine whether they put Children and Young People at more risk when used.
We couldn't complete an exhaustive test using all the UK Internet Service Provider's, so instead we selected Virgin Media as our benchmark provider. We were also going to use SWGfL’s Test filtering to see how it blocks harmful content when restrictions are added. For testing, we were going to use simple access requests to some of the most mainstream free pornography sites in the UK to see how effective filtering already was without using a VPN. We did this on a standard home network which would be common for most families to regularly use.
The first test was switching on all the Virgin router filtering options called ‘Websafe’ and then accessing pornography sites. Virgin quickly passed, and the access attempt was blocked. Next, we ran the SWGfL Filtering test, which confirmed that the Internet Service Provider ran the Internet Watch Foundation (IWF) Child Sexual Abuse Material (CSAM) list and prevented access. Satisfied that the filtering system was working correctly, we now ran the same test using the VPN's.
For each VPN test, they completely bypassed the filtering already provided by the Internet Service Provider, meaning pornography sites could be accessed freely. We also ran the VPN's through the SWGfL filtering test, and again, they failed. This wasn't unexpected as creating an encrypted tunnel will provide anonymity, making it difficult for the Internet Service Provider to see where you are going online and apply the necessary filters.
If we turn our attention to each of the VPN's themselves, it was important to see whether there was a way of turning on filtering within the software. From what we saw, the answer was no!
While a couple of the VPN's provided ‘split tunneling’, where you can create a list of sites where you don't want your VPN to be active, there was no blanket filtering option for harmful content. If a family household wished for a VPN to be on all the time, they would have to manually input each site they wanted the home ISP to block. Due to the vast nature of the internet and the unpredictable behavior around online activity, this is not exactly practical for families to implement.
When it comes to VPN’s, they can create a paradox: implementing them can help withyour own security online, however, without the filtering options from internet providers, VPN’s can expose more harmful content to the family. It’s important to fully understand what you are truly getting with a VPN so there are no surprises down the line. Make sure you consider what needs to be prioritized for the family and what would offer the most security or peace of mind.
So could VPN's enable filtering the same way that internet provides do? On the face of it, it should be possible. Several VPN's already have enhanced cybersecurity features, including blocking malicious sites. If they can do this for cybersecurity, then why not online safety? It's an interesting question and one we should be asking.
Take a look at the most commonly used VPN providers in the UK and see what they offer for your household.
Considerations: Nord VPN has a feature that blocks malicious websites that may contain malware and also incorporates a Split Tunneling feature, but their ethos of providing ‘online freedom’ with no filtering can potentially expose harmful content.
Considerations: Express VPN has the split tunneling feature which can allow some devices to get filtering benefits from noted websites through the Internet Service Provider while a VPN is established. If accessing direct through the VPN though, filtering may still be compromised and harmful content available.
Considerations: Proton VPN is a Switzerland based VPN provider that offers VPN protection without filtering harmful content, available in the UK. They also provide a free VPN that is only available to certain countries that has limited features. As this is based abroad, remember to understand what privacy laws are included which are different to UK and USA.
Considerations: Surf Shark is one of the cheaper options and includes many of the features available with VPNs. It also includes an unlimited device option meaning households are not restricted to what they want to link. Again, filtering options aside from cyber security don’t seem to be present.
Please note: Although some of these VPN options highlight protection from Malware, this primarily relates to blocking or avoiding malicious websites. Even with a VPN, users can still find themselves victim to viruses.
Taking into account all the above and from the VPN breakdowns, there are some clear advantages to using VPN’s. If there weren’t, then they wouldn’t be as actively used as they are today. The below are some of the key benefits of installing a VPN within your household:
As with advantages though also come disadvantages. VPN’s have yet to become a regular staple within the common household and there are still some concerns around how they can protect against other types of online harm aside from cyber security. The below are some of the disadvantages around VPN’s:
Having looked at VPN’s from various angles, it seems there is still some work to do around online safety and protection from online harm. VPN’s do offer the user some notable benefit around internet freedom and accessibility but unfortunately these benefits create disadvantages in themselves.
If you are considering using a VPN for the household, then it is important you are fully aware of what you are purchasing. Make sure it is well established and has the appropriate approvals in place. Do not download something just based on the price, make sure you are aware of all the features that it provides and think critically about how this could affect your day to day internet activity.
It’s important to determine levels of importance for your family’s internet usage. If you merely want to access media content abroad but still want to prioritise safety filters for the family, then a VPN may not be the best course to take. On the other hand, if you work from home and are concerned about security threats, then a VPN can provide some notable support.
