Sublime NLU 3.0: Faster, more accurate, future-proof defense against AI email attacks

Sublime has announced the release of NLU 3.0, a significant upgrade to its Natural Language Understanding model, designed to enhance email security by detecting sophisticated threats such as business email compromise and polymorphic phishing attacks. This new version leverages synthetic data augmentation with Generative AI and a unified multi-head architecture to improve the model's ability to understand email context and intent, thus reducing false positives and increasing threat detection accuracy. The model's modular design allows for rapid expansion, enabling it to adapt quickly to new attack patterns. NLU 3.0's insights are integrated into Sublime's Message Query Language (MQL), simplifying rule creation for security teams and helping them focus on real threats. This upgrade promises to outpace adversaries by adapting to evolving threats, offering a more resilient defense against GenAI-generated attacks while maintaining system performance and transparency.
