Vulnerabilities in air-gapped OT networks go far beyond software flaws. One of the biggest vulnerabilities is the devices carried through the door, including third-party vendor laptops and newly introduced workstations.
Recent industry data from the SANS 2025 ICS/OT and IBM’s 2025 Cost of a Data Breach reports confirm what we’re seeing across industries. Transient device attacks surged by 221%, with 27.3% of all OT incidents originating from transient devices, and third-party and supply-chain compromises averaging about $4.9 million per breach.
AI-Based Malware is the Fastest Growing Cyber Risk
Vendor laptops and new devices coming to sites are common entry points that threat actors often exploit. With AI-generated malware designed to evade signature-based engines, and AI-related vulnerabilities growing at 87% as the fastest-rising cyber risk, traditional malware scanning alone is no longer sufficient.
To address these risks, OPSWAT has embedded the OPSWAT Predictive Alin AI engine with both form factors, MetaDefender Drive™ and MetaDefender Drive with Smart Touch. It is included with every MetaDefender Drive engine package and both scan modes, pre-boot and in-session scanning.
The Manufacturing and Nuclear Sectors are Primary Targets for AI-Based Cyberattacks
The manufacturing sector accounts for 27% of reported cyberattacks. Of those hit by ransomware, 51% paid an average of $1 million as per accident. The ENISA (European Union’s cybersecurity agency) 2025 Threat Landscape report found that OT attacks now represent 18.2% of all cyber threats globally.
For nuclear facilities operating air-gapped networks, the risk extends beyond operational disruption. A single undetected file can lead to regulatory compliance failures and public safety implications. The NTI Nuclear Security Index found that 25% of countries with nuclear reactors lack basic cybersecurity measures.
Smarter Detection at the Perimeter, Built Into Every Scan
Predictive Alin AI is a machine learning engine built into MetaDefender Drive. It analyzes the file structure, entropy, and code semantics before execution, with no signature match, cloud, or detonation requirements. It runs alongside the existing Metascan Multiscanning™ technology stack as an always-on intelligence layer that activates precisely where traditional AV goes silent.
Detection Before Execution
Predictive AI helps stop threats before they reach the OT system. Verdicts are delivered in under 100 milliseconds for 99% of files, with no detonation required. In critical infrastructure environments where running an unknown file on a PLC or HMI is not an option, such as nuclear and manufacturing, this pre-execution protection is active in both MetaDefender Drive’s pre-boot and in-session modes.
Reduced False Positives
Trained on enterprise-grade, privacy-safe data streams, the engine was shown to report a ~0.1% false-positive rate and 99.99% precision on safe files. This enables technicians to scan a device at a remote substation or plant floor, knowing that legitimate control system files won't be incorrectly flagged, and that production won't be unnecessarily interrupted.
Zero-Day Threat Prevention
With AI-related vulnerabilities rising as the fastest-growing cyber risk, Predictive Alin AI continuously trains on sandbox-confirmed zero-days from MetaDefender Aether. It helps catch AI-generated and never-before-seen threats.
Improved Multiscanning Capability
MetaDefender Drive now scans with up to eight anti-malware engines simultaneously with a predictive intelligence layer added across all tiers. Predictive Alin AI fills the gap where those engines go silent, adding a decisive verdict layer that multi-engine scanning alone cannot replicate.
One Standard Across Both Form Factors
Predictive Alin AI is now included across all MetaDefender Drive configurations. This enables every technician equipped with MetaDefender Drive to carry an offline AI-powered portable detection tool that is built for fast, precise threat prevention in environments where the stakes are highest.
