While Internet connectivity in the home is now mainstream, gateway security to protect users is not. It’s a gap that startup Itus Networks is aiming to address with a Linux-powered home gateway device called the iGuardian. Before Itus can deliver the iGuardian though, the company needs to raise $125,000 on crowdfunding site Kickstarter in order to build the device. The Kickstarter campaign ends on Sept. 12, and as of Aug. 19, $61,000 has been raised.
