The Internet is a wonderful tool, but it is not without its dangers. There are all kinds of security threats online that you should stay clear of. iGuardian can help you out. It is designed to keep all your connected devices safe against malware, exploits, and any other danger. It can protect computers, electronics, and smart home devices against cyber attacks.
This small device does not require a whole lot of space. The embedded Linux system is based on OpenWRT and runs Snort as an in-line intrusion prevention system. It inspects all incoming and outgoing traffic to identify known attacks. Offending packets are dropped and connection is reset to prevent attacks from reaching their target. iGuardian is on Kickstarter right now.
