Apozy Airlock NoHack is a browser-based security tool that uses neural networks to detect malicious websites in real time, including zero-day phishing sites and malvertising that have not been previously reported or catalogued. Unlike traditional signature-based antivirus solutions, NoHack relies on visual analysis models to identify malicious sites by appearance rather than known signatures. This allows it to detect threats that are entirely new and unknown at the time of encounter. The product operates on a collective defense model through a global sensor network. Each user within an organization running NoHack functions as a sensor. When one user encounters and flags a malicious site, that threat data is shared across the entire NoHack community network. Other organizations on the network are then alerted and protected before their users encounter the same threat. The visual model database is continuously updated as the sensor network grows, improving detection accuracy over time. The community-based approach is designed to protect against phishing sites and malicious ad networks (malvertising) by enabling early detection and rapid information sharing across participating organizations.
