F‑Secure Router Checker

An internet router is a device that connects other devices to the internet. Instead of every device connecting directly to the internet, they connect to the router. The router then routes the flow of data to and from the devices connected to it.

Most devices are incapable of connecting online without a router in between. Computers and mobile devices as well as many smart devices such as home appliances, entertainment systems and gaming consoles are typically connected to the internet via a router. Nowadays this usually happens wirelessly with a Wi‑Fi network created by a router.

By managing all internet traffic, the router plays a big role in keeping internet-connected devices in a wireless network safe from outside threats, such as hacking attempts and denial of service (DoS) attacks. Luckily, many routers offer additional safety features that make connecting to the internet safer. You should still be aware of and prepared for potential threats to your router, and as a consequence, all devices in the network.

F‑Secure Router Checker shows the known vulnerabilities to the router type, not your individual router. The improvements you make do not affect the listing, but they do greatly improve your router security.

We use the leading U.S.-managed database of cybersecurity vulnerabilities, National Vulnerability Database (NVD). The vulnerability descriptions are often very technical. To help everyone understand the vulnerabilities, we have tasked AI to write the descriptions with more accessible terms. We are certain that the AI explanations help more people understand the security and possible threats related to their router.

The previous version of Router Checker focused only on checking the router's DNS settings. As DNS hijacking has become a lesser threat, the technology and purpose behind the previous version of this tool became outdated. That's why we have updated it. The new version looks into all known vulnerabilities of a router type, which gives a better picture of router security.

Router security is dependent on the manufacturer. While the F‑Secure app doesn't protect your router, you can protect your computers, phones and tablets with it. This gives you good protection against most online threats.

However, F‑Secure works with multiple major router manufacturers and operators to protect users against router-based threats. Unfortunately, F‑Secure’s router-based security can’t be installed on routers that don’t already have it pre-installed. But luckily, by following our tips on protecting your router and protecting your online-connected devices with complete protection, you can effectively secure everything you do online.

We use the leading U.S.-managed database of cybersecurity vulnerabilities, National Vulnerability Database (NVD). The NVD provides detailed information on vulnerabilities, including severity scores and software version identifiers. Our tool shows up to 10 most recent vulnerabilities. However, it’s important to note that the information in the NVD may not always be complete or perfectly accurate.
