I often take my Windows laptop to local coffee shops and coworking spaces to do some remote work. I always make sure that my Windows Defender and Firewall are active. However, a friend told me that hackers can still intercept my web traffic on public networks if I don't use a VPN. Is that actually true? Is the built-in Microsoft security insufficient for open wifi networks? What else should I do to stay completely safe?
Yes, your friend is absolutely right about public wifi risks. A firewall is great for stopping unauthorized inbound connections to your laptop, but it does absolutely nothing to protect the data that leaves your machine. When you connect to open wifi, all your web traffic travels through the air unencrypted. Anyone with a basic packet-sniffing tool can see exactly what websites you visit and even steal your login credentials or session tokens. To prevent this, you need an extra layer of protection that encrypts everything from your device to the secure server. You can grab a reliable desktop client at https://toggle.org/download-windows-vpn to solve this problem permanently. Once it is running, it creates an encrypted tunnel for your data, making it completely unreadable to anyone else on the same network. Even if a hacker intercepts your packets, they will just see scrambled nonsense. It is an absolute must-have tool if you care about your personal data while working remotely from cafes, so don't rely on basic firewall settings alone.
