The Phone Paradox: Why Physical Security Is Non-Negotiable

In the sectors of national defense and critical infrastructure, the definition of a “secure room” is changing. We have spent decades securing our networks, but we often ignore the most common microphone in the room: the one in our pocket.
The Acoustic Gap in Modern Cybersecurity

We live in an age of end-to-end encryption. We trust our digital tunnels, but we often ignore the fact that every conversation begins as a physical sound wave. If a compromised phone is in the room, that “unencrypted” sound is captured before it ever reaches a secure app.
The New Meeting Ritual: Integrating Shield into Your Workflow

Security protocols are only effective if they are followed. If a measure is too complex, it becomes a hurdle. link22 Shield was designed to be a natural extension of the professional meeting environment.
The Mechanics of Acoustic Neutralization

In the world of intelligence and sensitive R&D, we often focus on the “flashy” side of cybersecurity, firewalls and encryption. But the most vulnerable point in any secure facility is often the air itself. Specifically, the sound waves carrying your most confidential ideas.
Why Physics Trumps Digital Policies: The Case for Physical Acoustic Security

In the contemporary cybersecurity landscape, our instinct is almost always to seek a digital solution for a digital threat. We deploy firewalls for network intrusions, encryption for data theft, and multi-factor authentication for identity breaches. However, there is one critical vulnerability that digital tools are fundamentally ill-equipped to handle: the acoustic leakage of sensitive conversations through mobile devices.
Why a “Dark Screen” is not a Security Guarantee

The most dangerous security threats are the ones we stop noticing. In the government & public sectors, smartphones have become such a ubiquitous part of our environment that we often forget they are essentially sophisticated bundles of sensors, cameras, and, most importantly, microphones.
Solving the Conflict Between Device Possession and Meeting Privacy

In the world of high-level cybersecurity, few things are as frustrating as the “Security Paradox.” For those working in government, military, or critical infrastructure, the smartphone is a double-edged sword. On one hand, it is a vault containing your digital life – authentication keys, encrypted messages, and sensitive access. You are taught never to leave it unattended. On the other hand, that same device is a sophisticated listening tool that can be remotely hijacked to record every word spoken in a secure room.
We Launch Data Guard Version 3.12 – An Update for Safer Transfers

link22 now launches an updated version of our core product within Secure Transfer, Data Guard. With improved functionality and increased flexibility in version 3.12, we now offer even stronger protection for critical data.
link22 Launches Diode TCP Connector: Secure Streaming of TCP

link22 introduces a new product, the Diode TCP Connector, enabling secure streaming of TCP data over a physical data diode. This innovation provides a secure solution for channeling external data streams into an offline IT environment or exporting sensor data and logs from a power facility.
Cybersecurity: A Cornerstone for a Secure Society

In a world where technology is constantly evolving and digitalization is accelerating, cybersecurity is more crucial than ever. link22 assists government, defense industry and large corporations in protecting their critical information and infrastructure.
