It aims to shift from reactive fixes to preemptive protection against major threats, including zero-day vulnerabilities. The system uses a two-phase approach: a supervised global model for known attack patterns and an unsupervised local model for real-time, application-specific learning. This dual-engine process ensures precise threat detection by understanding both global attack indicators and local application behaviors. The engine also includes comprehensive security layers such as API security, intrusion prevention, anti-bot capabilities, file security, and advanced rate limiting. It is designed for modern infrastructures, supporting cloud-native and CI/CD environments, and is open-source under the Apache 2.0 license. The technology promises to reduce the operational overhead of security teams, allowing them to focus on higher-level strategy. The page concludes by posing a thought-provoking question about the future role of security analysts in an era of preemptive, self-learning security solutions.
