Hardware-Enforced Security for Sensitive Audio Video Environments
HighSecLabs (HSL) is a cyber security company that designs hardware-enforced secure KVM switches, media diodes and secure audio video distribution products for organizations that operate multiple isolated networks of different classification levels. Rather than relying on software encryption, which can be patched, hacked or bypassed, HSL builds security into hardware through unidirectional data diodes, optical isolation and pre-certified components that cannot be reprogrammed after manufacture.
HSL's secure KVM solutions and secure peripheral sharing devices are used by defense, government and high-security enterprise environments worldwide to prevent network infiltration, data leakage and eavesdropping. Its product lines are certified to rigorous standards including NIAP Common Criteria, FIPS 140-3 and TEMPEST, and its Secure, Rugged and Commercial product lines cover everything from control rooms and secure desktops to tactical field deployments.
ARK Infosolutions brings the HighSecLabs portfolio to organizations across India that need to secure how data moves between classified and unclassified systems, with support spanning solution design, deployment, training and ongoing technical assistance.

Audio Video Distribution
The need to distance computers from user-facing areas is common in secure organizations, where systems are kept in access-controlled server rooms. HSL's Audio Video distribution range uses hardware-based media diodes and single-strand fiber optic AV extenders to move video, audio and USB signals over long distances, and to eliminate the eavesdropping and data exfiltration risks that come with shared audio and video peripherals.
HSL's media diodes connect between a source computer and an audio or video device such as a speaker, headphone, microphone, webcam or videobar, and enforce a unidirectional flow of data. This prevents attackers from repurposing a speaker as a microphone, from transmitting data through high-frequency audio signals, or from using a shared webcam to move data between networks. Every Audio Video extender in the HSL range carries EAL4+ certification and hardware-based optical data diode isolation, so isolation never depends on software configuration that can be misconfigured or bypassed.

Secure Meeting Rooms
Meeting rooms carry more risk than most security teams account for. Guest devices, videobars, smart TVs and commercial KVM switches all present entry points for network infiltration, peripheral surveillance and acoustic data exfiltration. SoundSentry is HSL's secure conference room solution, purpose-built to close these gaps and allow the same room to host both classified and unclassified discussions with a seamless switch between modes.
SoundSentry is the world's only solution specifically designed to enable discussions of any classification level in a single, dual-use meeting room with a seamless transition between modes. By introducing hardware-level measures to the conferencing infrastructure, any meeting room can be hardened against data breaches and eavesdropping attempts.
Uninvited threats have joined your meeting
Network infiltration
Compromised guest devices gain direct access to secure networks by exploiting KVM switch and peripheral device vulnerabilities.
Peripheral surveillance
Microphones, speakers, displays and cameras can be exploited for persistent eavesdropping, malicious code injection and data exfiltration.
Acoustic exploitation
Speakers can be manipulated to deliver high-frequency audio signals that exfiltrate data.
Key Components of a Secure Meeting Room Setup
Share Peripherals, Not Data
SoundSentry establishes a hardware-enforced barrier that enables the use of a single set of peripherals across classified and unclassified networks without bridging the air-gap.
Secure Peripheral Sharing
HSL's NIAP-certified KVMs enforce absolute data isolation, making data leakage between sources impossible while a single set of peripherals is shared across multiple air-gapped networks.
Unidirectional, Wired Data Flow
HSL's media diodes create a physically enforced, unidirectional data path, making it impossible for data to leak back from a media device to the source computer.
Smart Power Management
Instantly hardens meeting room security by cutting power to vulnerable peripherals like displays and videobars, a true hardware disconnect that a simple software mute cannot match.
Adaptive Configuration for Every Environment
SoundSentry can be integrated into any meeting environment. Executive offices, conference rooms and board rooms each come with their own set of vulnerabilities, and SoundSentry adapts to each with the same hardware-enforced approach to secure meeting room and secure conference room protection.
FAQ's
A secure KVM switch allows one keyboard, monitor and mouse to control multiple computers connected to different, often air-gapped, networks, while enforcing hardware-level isolation so data cannot cross between them. HighSecLabs secure KVM solutions help defense, government and high-security organizations maintain separation between classified and unclassified systems as part of their Secure AV Solutions infrastructure.
A media diode enforces a one-way data path, physically preventing information from flowing back from a display, videobar, speaker or other peripheral to the source computer. Unlike software-based controls, the isolation is built into the hardware, making HighSecLabs media diodes suitable for secure Audio Video distribution, secure meeting rooms and other security-sensitive AV environments.
