Patented port locks, cable locks, and I/O security devices for the Americas — direct from the original inventors with 15+ years of hardware security innovation.
For more than 10 years leading up to 2025, our patented physical security hardware was widely distributed and trusted across the US market through various partner channels. Now, the original engineering team and global pioneer behind that exact technology, COMXI (now officially SMARTKEEPER Co., Ltd. of South Korea), is proud to introduce our dedicated brand for the Americas: portArgus.
To ensure supply chain stability and provide direct manufacturer support in the United States, Canada, Mexico, and Brazil, we are consolidating our product identity under the portArgus name.
Seamless Integration: 100% backward compatible with your existing installations. No changes or key replacements required on your end.
Direct from the Source: If your infrastructure currently relies on the original hardware engineered by our Korean headquarters, portArgus is the exact same technology you already trust — the identical patented technology and precision, now supported directly by the true original manufacturer.
portArgus offers a comprehensive suite of physical cybersecurity solutions — port locks, cable locks, and numerous I/O security devices — designed to protect your infrastructure from unauthorized access.
We are not just a reseller — we are the original inventors with over a decade and a half of expertise in hardware security. Every product embodies years of engineering precision and field-tested performance, built by the team that defined the category.
Our unique locking mechanisms are protected by multiple US and foreign patents, ensuring exclusive security performance. No imitation delivers the same physical integrity as the original. When a port is sealed by portArgus, it stays sealed.
By choosing portArgus, you work directly with the source — ensuring faster response times, reliable inventory, and technical support from the engineers who built these systems. One point of contact. Every gate, covered.
