Lasso Security is an AI security platform that provides end-to-end protection for enterprise GenAI adoption through a five-pillar framework: Discover, Assess, Test, Enforce, and Protect. The platform processes security decisions in under 50 milliseconds with 99.8% detection accuracy, making it one of the faster options in the AI security space alongside tools like Lakera Guard.
Founded in 2023 by Elad Schulman (CEO), Ophir Dror (CPO), Lior Ziv (CTO), and Yuval Abadi (COO), Lasso Security is an Israeli cybersecurity company that emerged from stealth with a $6 million seed round led by Entree Capital. The company has since raised $28 million in total funding from investors including Samsung Next, Singtel Innov8, Selah Ventures, and ClearSky.
Lasso was named a Gartner Cool Vendor in 2024 and has received recognition from NIST. The board includes Naftali Bennett (former Israeli Prime Minister and former CEO of Cyota, acquired by RSA) and Dean Sysman (co-founder of Axonius).
Customers include the US Department of Homeland Security, eToro, Kaltura, Artlist, Optibus, Guesty, Telit, and Nayax.
Lasso has also received the Global InfoSec Awards Winner 2026, InfoSec Award 2025, and Forum IT 100 recognition. The company is an AWS Startup participant and Microsoft for Startups member.
What is Lasso Security?
Lasso Security takes a lifecycle approach to GenAI protection through a five-pillar framework: Discover, Assess, Test, Enforce, and Protect. Each pillar addresses a different stage of the AI security challenge, from finding out what AI tools employees are using to blocking attacks against production AI systems in real time.
The platform processes decisions in under 50 milliseconds with 99.8% detection accuracy across content, context, and intent analysis. Lasso claims this is 570x more cost-effective than cloud-native guardrails, based on vendor benchmarks.
For agentic AI specifically, Lasso developed the Intent Security Framework — a behavioral baseline approach that monitors not just what AI agents do, but what they intend to do. This is critical as organizations deploy autonomous agents that interact with tools, data sources, and MCP servers without direct human oversight.

Five-pillar framework
Lasso’s security model is organized into five distinct stages. Discover maps the AI landscape, identifying every model, agent, and tool in use. Assess evaluates supply chain risks and security posture across the AI stack. Test runs adversarial simulations using 3,000+ attack techniques. Enforce applies guardrails and behavioral specifications to AI workflows. Protect monitors AI interactions in real time and blocks malicious activity as it happens.
Each pillar feeds data into the next, so the platform builds a continuously updated picture of an organization’s AI risk profile.
Agentic AI security
As AI agents become more autonomous, Lasso’s Intent Security Framework addresses the unique challenge of securing non-human actors. The framework establishes behavioral baselines for agents — what they should be doing, what tools they should access, and what data they should handle — then flags deviations in real time.
This extends to MCP security, where Lasso monitors the communication between agents and the tools and data sources they access through Model Context Protocol servers.
Getting Started
When to use Lasso Security
Ideal for organizations that need lifecycle coverage for their AI security — not just runtime defense, but discovery, assessment, testing, and governance as well. The sub-50ms classification speed keeps the platform from becoming a bottleneck in production environments, and the 3,000+ attack library provides thorough adversarial testing.
Regulated industries like healthcare, finance, and public sector benefit most, since shadow AI discovery and compliance documentation matter as much as threat detection there. The Intent Security Framework also makes Lasso a strong choice for organizations deploying agentic AI at scale.
