SenTeGuard
SenTeGuard provides real-time security controls for AI interactions, intercepting and analyzing every prompt and response to prevent leakage of classified data, trade secrets, and proprietary information. The company also offers MoyoMap, a tool that transforms AI responses into explorable claim maps, and Moyo Scan, which produces point-in-time research reports on what public AI systems can assemble about a person, company, or topic.

Problem
Traditional network security defends infrastructure but fails to protect the meaning flowing through AI interactions—classified data, trade secrets, and proprietary information can be leaked through LLM prompts and responses. Existing DLP tools only match exact patterns, missing semantic leaks like describing a trade secret in natural language or combining innocuous public data into sensitive conclusions.
Solution
SenTeGuard deploys as a real-time proxy between users and LLM endpoints, intercepting, analyzing, and enforcing policy on every AI interaction before damage occurs. The inspection engine scans inputs for PII, classified markers, prompt injections, and proprietary code patterns, then blocks, redacts, or flags content based on custom rulesets. Output validation checks responses for leaked system prompts or training data, while full audit logging captures every interaction for compliance reporting. Complementing the proxy, Moyo provides attack-path analysis for information reachability, mapping how public sources can be combined via LLMs to infer sensitive facts—treating inference itself as an exfiltration channel. Additionally, MoyoMap turns AI responses into an organized, explorable map of claims that teams can review, source, and expand, while Moyo Scan offers point-in-time research reports on what public AI systems can already assemble about a person, company, or topic.
Target Audience
Primary customers are defense contractors handling CUI/classified data, financial services under SEC/FINRA obligations, healthcare organizations under HIPAA, and enterprises with 50+ employees using AI tools, as well as intelligence organizations and enterprises with sensitive IP needing inference exposure assessment.
