The FritzBox is the gateway to the internet and a popular target for hackers

Your FritzBox is the central hub for your internet connection, effortlessly providing Wi-Fi to your computers, smartphones, and various other devices. Given its pivotal role, its security is of utmost importance. However, many users set up their FritzBox just once and then forget about it, making it a vulnerable entry point and a prime target for hackers. Once a cybercriminal gains access to your FritzBox, it's like hitting the jackpot. From your router, they can access all devices connected to it, giving them entry to your private data, passwords, and more. To protect you from this danger, we developed RouterGuard. In addition to providing comprehensive security, RouterGuard offers features such as voicemail access and automatic blocking of scam numbers, making it an even more effective solution to maximize your protection. This way, you remain in full control—even when receiving phone calls.

Attack on your FritzBox? RouterGuard sounds the alarm

RouterGuard monitors your FritzBox for suspicious activity and provides real-time updates on what’s happening in the background. The dashboard shows you how many of your FritzBox settings are already optimized for high security, and with just one click, you can access detailed explanations of these settings and be redirected to your FritzBox interface to make adjustments. Through customizable blocklists, you can also easily block phone numbers you don’t want to receive calls from—quickly and conveniently. This way, your FritzBox is protected on all fronts.

Who is connected to my Wi-Fi? No chance for unauthorised users

RouterGuard allows you to see all devices connected to your FritzBox and Wi-Fi network. You get a detailed overview of all the devices accessing your network, while also detecting any unauthorized users who shouldn't be there. If your neighbor is hogging your Wi-Fi and slowing down your internet speed, or if a hacker is trying to steal your private data or passwords, RouterGuard lets you take immediate action. Thanks to features like automatic blocking of scam numbers and voicemail management, RouterGuard is your all-in-one solution for complete peace of mind. If any suspicious activity is detected, you'll be notified right away, so you can respond instantly.
