Lakera AI vs Duckie

About

Lakera AI is an AI security company founded in 2021 and headquartered in Zurich, focused on protecting large language model applications from adversarial inputs and unsafe outputs. The company's flagship product, Lakera Guard, acts as a real-time security layer between user inputs and LLM APIs, detecting and blocking prompt injection attacks, jailbreak attempts, toxic content, and sensitive data exposure. As enterprises race to deploy LLM-powered products including chatbots, copilots, and autonomous agents, Lakera has emerged as a critical security infrastructure provider for AI application teams. The platform integrates as a lightweight API call and supports major LLM providers including OpenAI, Anthropic, and open-source models. Lakera also created Gandalf, a widely shared gamified prompt injection challenge used to demonstrate LLM vulnerabilities. The company serves enterprises in financial services, healthcare, and technology building production LLM applications that require robust safety and security guardrails.
