OPSWAT has successfully demonstrated the resilience of its prevention-first cybersecurity technology by sending its MetaDefender Kiosk Mini on a near-space mission, validating its ability to protect critical infrastructure even in some of the world’s harshest operating environments.
The rugged cybersecurity appliance, designed to sanitize USB drives, removable media and external storage devices before they connect to critical systems, remained fully operational throughout the mission, processing thousands of malware samples while operating offline.
Attached to a weather balloon, the MetaDefender Kiosk Mini ascended to an altitude of 104,883 feet (31,968 metres), where it encountered near-vacuum atmospheric pressure, intense ultraviolet radiation and temperatures as low as -43.1°C. Even after the balloon burst and the device entered freefall before landing in a river, it continued functioning throughout the journey.
The mission was designed to demonstrate that cybersecurity systems protecting critical infrastructure must remain operational even when cloud connectivity, software updates or onsite technical support are unavailable.
According to OPSWAT, the demonstration reinforces the importance of prevention-first cybersecurity, particularly for mission-critical environments such as space infrastructure, defence systems, industrial operations and other remote facilities where connectivity may be intermittent or completely unavailable.
“Cybersecurity in space cannot be built around the idea that someone on Earth will always be available to fix the problem. It must be local, deterministic, segmented, and prevention-first.”

The company’s MetaDefender Kiosk Mini uses its proprietary Deep Content Disarm and Reconstruction (Deep CDR) technology, which assumes every incoming file may be malicious, removes potentially harmful active content and reconstructs a clean version before allowing it into protected environments.
The system performed all malware analysis locally during the mission without relying on cloud-based processing, highlighting its suitability for isolated and air-gapped environments.
OPSWAT noted that the growing reliance on satellites and other orbital assets is expanding the cybersecurity threat landscape. Citing the World Economic Forum’s Global Cybersecurity Outlook 2026, the company said 15% of organisations now consider dependence on space-based assets as part of their overall cyber risk management strategy.
As governments and commercial organisations continue expanding their space operations, future cyber threats may increasingly target satellites, spacecraft and orbital infrastructure through techniques such as electronic warfare, signal jamming, spoofing and cyber intrusion.
Benny Czarny, Founder and CEO of OPSWAT, said space infrastructure should be treated with the same cybersecurity rigor as other critical infrastructure sectors.
During the validation mission, the MetaDefender Kiosk Mini successfully withstood constant movement, extreme temperature fluctuations, high UV radiation, humidity, water exposure, near-vacuum pressure and prolonged offline operation.
The company said the same rugged platform is already deployed across industries such as oil and gas, mining, chemical processing and manufacturing, where harsh environmental conditions and removable-media threats require reliable, air-gapped cyber protection. The device also carries UL Class 1, Division 2 certification, allowing deployment in hazardous industrial environments where flammable gases or vapours may be present.
The near-space mission underscores OPSWAT’s broader vision of developing autonomous cybersecurity systems capable of protecting mission-critical environments where human intervention may be delayed or impossible.
