Blink is an endpoint security product that functions as a network protector. A unique component is that Blink works like a host-based IPS (HIPS) system by trying to stop malware from making it to the endpoint. A unique aspect is that the product attempts to replace desktop security components by providing a single product, thereby minimising the memory footprint needed to secure the machine. Blink works with only Windows clients but does support the 64-bit versions of operating systems.
