Lasso Security

Lasso Security is an LLM security and governance startup that focuses on protecting organizations from the emerging risks associated with large language model adoption, including shadow AI usage, data exfiltration, and unauthorized LLM interactions. Founded in 2023 and headquartered in Tel Aviv, Israel, Lasso Security addresses the growing enterprise concern that employees are using generative AI tools in uncontrolled and potentially risky ways, creating security blind spots that traditional security tools cannot detect. The platform's core capability is shadow AI detection and monitoring, which identifies and catalogs all LLM and generative AI tools being used across an organization, whether sanctioned or not. This includes tracking interactions with public AI services like ChatGPT, Claude, Gemini, and other generative AI platforms, as well as monitoring usage of internally deployed LLM applications. By providing visibility into how AI tools are being used across the organization, Lasso Security enables security teams to understand their AI exposure and enforce appropriate usage policies. Beyond discovery, Lasso Security provides real-time monitoring and policy enforcement for LLM interactions. The platform can detect and prevent sensitive data from being shared with external AI services, block prompts that violate organizational policies, and maintain audit logs of all AI interactions for compliance purposes. These capabilities are particularly important for organizations in regulated industries where data governance requirements extend to AI tool usage. Lasso Security integrates with enterprise network and endpoint security infrastructure to provide comprehensive visibility without requiring changes to existing workflows. The platform supports policy-based controls that can be tailored to different user groups, departments, or data sensitivity levels. While Lasso Security is a very new startup still in the early stages of building its product and customer base, it addresses a timely and genuine security concern that many organizations face as generative AI adoption accelerates across their workforces. The company is best suited for mid-market organizations that are grappling with the challenge of enabling productive AI usage while maintaining security and compliance standards. As the market for LLM security matures, Lasso Security's early focus on shadow AI detection positions it to capture demand from organizations seeking to regain control over their AI landscape.
