GenAI isn’t the threat. Misuse is.
Employees are sharing sensitive data into ChatGPT, CoPilot, and Gemini every day.
Contracts. Financial models. Customer records.
Legacy DLP can’t stop it because it doesn’t understand context. AI DataFireWall™ scans, pseudonymizes, and protects your data before it ever leaves your organization.
Every company using AI today is naked. Contextul makes you bulletproof.
Legacy DLP is Broken. We Fix It.
Traditional Data loss prevention (DLP) tools weren’t built for natural language prompts. They don’t catch context, intent, or cleverly phrased questions that hide sensitive data. AI DataFireWall™ sits between your users and GenAI platforms analyzing every prompt, attachment, and interaction in real-time.
We stop what others miss.
Pseudonymization, Not Just Detection
Contextul replaces risky data with fabricated data so nothing sensitive ever reaches the LLM.
-
Scrubs and replaces names, financials, medical data, legal content, and more
-
Maintains productivity by rehydrating safe results post-response
-
Built to meet GDPR, HIPAA, CCPA, and 25+ global data laws
Enable secure GenAI use. Without compromise.

Working With the Best
Working with Contextul has been an absolute pleasure. They supported us with GDPR elements and were incredibly knowledgeable and reassuring throughout the process. Big shout out to Darren and Robert for their efficiency, responsiveness, and ability to jump in whenever needed. They made a potentially complex area feel manageable, and their professionalism and helpfulness gave us real confidence. I’d highly recommend Contextul to anyone looking for expertise and a great team to partner with
