Lasso Security vs Prompt Security

Lasso Security provides an AI Security Platform that delivers visibility, control, and protection across AI models, agents, and applications for enterprises. The platform inventories AI assets including agents, models, prompts, tools, and guardrails via discovery and AI-BOM features. It offers AI Security Posture Management for misconfigurations, supply chain risks, and alignment with NIST and OWASP frameworks. Automated red teaming uses a library of over 3,000 attacks covering OWASP Top 10 and agentic threats like context poisoning. Runtime enforcement provides zero-latency decisions with remediation guidance, while AI Detection & Response leverages MITRE and OWASP for threat detection with 98.6% accuracy and sub-50ms latency, including intent analysis for anomalies. Lasso targets enterprises adopting GenAI, particularly regulated sectors, enabling secure innovation through real-time risk reduction, governance, and compliance support. The platform maps to frameworks like NIST AI RMF, EU AI Act, and ISO/IEC 42001 via runtime policies and audit trails, integrating with tools like Cloudflare and Palo Alto Networks.
