When I check out Reddit, I notice a lot of folks think VPNs are a magic shield against all malware, public Wi-Fi risks, and that they guarantee total anonymity. I just want to clarify that this isn’t entirely accurate. With my background in cybersecurity, I can tell you that whether or not a VPN is effective really depends on your specific threat model and personal preferences.
A VPN is ideal for people who want to access content that is blocked in their country, download torrents, hide their IP address, or keep their online activities private from their internet provider.
VPNs suggest that you are at risk on public networks, and this might have been true years ago. Today, most of our internet traffic is secured with TLS or HTTPS, which is used by many websites and apps. This means that while your Internet Service Provider or the public network owner can see the sites you visit, they cannot see your activities on those sites, like logging into your bank account. A VPN provides extra security by encrypting HTTP sites, but honestly, how often do you visit an HTTP site or enter personal information on one?
VPN companies often claim they can keep your data and browsing private from your ISP and the government. However, when you use a commercial VPN, you are shifting your trust from your ISP to the VPN provider. Personally, I would prefer to trust a smaller British ISP, which is regulated by the government regarding privacy, rather than a large tech VPN company that might log my data. Some may argue that VPNs offer no-log encryption but there is no guarantee of that claim, even with audits. Just look at their privacy policy; it reveals a lot. There is no way to be completely private online, and sadly, in today’s digital world, you have to place your trust in someone. Oh, that's also a message to tell you not to do anything illegal online when using a VPN.
Some VPNs can help block ads and protect against malware, but that's not their main job. If you want to avoid annoying ads and malware, consider getting antivirus software and an ad-blocking extension. For general hacking threats, no product, including VPNs, can fully guarantee your safety. It's important to use common sense: create strong passwords, enable two-factor authentication, limit personal info sharing, and avoid clicking on links or files from unknown sources. Interestingly, 81% of hacks happen due to weak passwords, so using a password manager can help keep you safe.
Some of you might be at a greater risk of being attacked, and I understand that. However, if you really care about your privacy, using a commercial VPN shouldn't be your main focus. You can consider other options like avoiding public networks, using your own hotspot, trying Tor, using decentralized VPNs, or even setting up your own VPN server for better privacy and anonymity.
I welcome everyone to share their opinions on this topic, and I don't consider myself overly concerned about privacy. If you choose to use a VPN, that's completely fine, but make sure that paying for a commercial VPN is worth it for you.
