Cybersecurity is a constant, ever-evolving problem that affects all of us. Especially data breaches and malicious intrusion would be the biggest of it. Indeed, Forbes reported that 4.1 billion records were exposed within the first six months of 2019. Most companies prepared software security already. But now, it is time to prepare physical security to have Double-layer security. SMARTKEEPER works physically. Port Lock blocks various input/output ports from USB Type A, B, C port to a Network port. Also, cable locks tether devices such as USB cables & LAN cables from the port to restrict unauthorized unplugging. 23 products exist in various computing environments.

One of the best sellers of SMARTKEEPER, RJ45 Port Lock, is applied in various industries to prevent data breach and intrusion of malicious code or virus into the internal network of the system via RJ45 Ethernet port. By hand, you can easily install the RJ45 port lock into the port but without the same colored (patterned) key (Lock Key Basic, U03), it is very hard to remove the port lock from the port. Especially RJ45 port lock of SMARTKEEPER is improved product rather than any competitor's products that the internal structure were developed to lock-in inside of the port for strong attachment.

Blocking all unused RJ45 ports creates another security demands for cables. If you can unplug the LAN cable which is plugged in, that means someone can unplug and might insert their own cable for malicious purposes. Therefore not only blocking unused ports but it is also important to lock the using LAN cables. SMARTKEEPER ESSENTIAL is a physical cybersecurity solution for all possible intrusion.

The wide compatibility of the Lock Key Basic (U03) can unlock 13 products for different types of ports. And Lock Key Mini (U04) can unlock 10 other lock products for smaller ports. It means that the client doesn't need to buy every separate key for every different lock of different type of port (e.g. USB, RJ45, SD, CF, USB Cable, LAN Cable). The advantage of SMARTKEEPER is a full lineup.
This is a physical cybersecurity device that prevents unauthorized connection to an unused RJ45 Ethernet port.
