Comprehensive cybersecurity for Large Language Models (LLMs), safeguarding against threats such as model theft, malicious code generation, and prompt injection MoreLess
Lasso Security operates in the cybersecurity sector, specializing in the protection of Large Language Models (LLMs) and Generative AI technologies. The company provides a platform that offers end-to-end security solutions, designed to safeguard against a range of threats specific to this emerging field. These threats include model theft, malicious code generation, prompt injection, and data poisoning.
The platform works by autonomously monitoring all interactions with GenAI systems, enabling real-time risk detection and response. This allows organizations to adopt and utilize LLMs while maintaining a secure posture. The company's services are aimed at enterprises that are integrating GenAI and LLMs into their operations and development workflows, including the use of AI code assistants.
Lasso Security's business model is likely B2B, offering its security platform as a service to these enterprises. The company has also established a partner ecosystem to extend the reach of its security solutions. Having recently emerged from stealth with $6 million in seed funding, the company is positioning itself as a key player in the nascent market for GenAI cybersecurity.
