Read full description
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.
