Lasso Security Review: Features, Pricing & Integrations 2026
Enterprise security teams use Lasso to block prompt injections and data leaks in real-time, though the early-stage tool has limited public reviews.
Expert Analysis of Lasso Security
Lasso sells two priced things under one name: a staff-chatbot product and an LLM gateway, quoted separately on its marketplace listing, with a per-unit charge stacked on top of the annual commit. Neither has a self-serve tier, so it is an enterprise buy.
Oleh KemFounder & Lead AnalystPrompt Injection Blocking on LLM API Traffic
Lasso sits inline on LLM API traffic and blocks prompt injection attempts in real time, preventing users from jailbreaking or overriding system instructions in production apps.
PII Redaction Before Data Reaches the Model
Lasso's data privacy layer scans incoming prompts for credit card numbers, SSNs, and email addresses, redacting or blocking the call before any sensitive data hits the LLM.
Custom Topic Filtering Tuned to Your Use Case
Policy rules let teams define blocked topics beyond general toxicity, so a financial app blocks competitor mentions while a children's platform blocks age-inappropriate content.
