In their own words
Lasso AI Security Platform
Lasso AI Security Platform provides observability, governance and runtime defense for enterprise AI environments. It inventories AI applications, agents, tools, MCP servers and connected resources, then maps relationships among agents, databases and APIs to identify misconfigurations and policy gaps. Automated red teaming tests applications in static, dynamic and high-agency modes. At the gateway, Lasso inspects prompts, responses, tool calls, MCP communications and sub-agent traffic; policies can block, mask or alert on violations with enforcement under 50 milliseconds. Shadow AI monitoring covers more than 8,000 tools, including chatbots, coding assistants and MCP servers. Supported agents include Vertex AI, Microsoft Copilot, AWS Bedrock, Salesforce Agentforce and custom platforms. Activity and audit trails map to listed security and regulatory frameworks. Deployment can use browser extensions, proxy integrations and data integrations in a hybrid model. Pricing is available on request.
