The best thing to fortify your devices when using your hotel’s Wi-Fi or any unsecured Wi-Fi is a VPN. A VPN works by encrypting the data coming from your device, sending it through a secure tunnel connecting the client (you) and the requested server (website). If you can’t use a VPN, ensure the web pages you visit at least have HTTPS at the front of the website’s address. This means the connection between the web page and the server is encrypted, offering you some form of protection. Another great safety measure is keeping your firewall enabled. Firewalls protect your devices from data-based malware threats.
