Why PrivateGPT?
Security and compliance are critical when using LLMs. You need a solution that safeguards sensitive data, ensures responsible AI use, and adheres to Data Protection Laws.
At Wald.ai, we help organisations in 3 ways:
1. Private, Secure Access to Leading LLMs
Leverage top LLMs—ChatGPT, Claude, Gemini, DeepSeek, LLAMA—without exposing sensitive data.
- • Real-Time Redaction: Sensitive data is removed before reaching the LLM.
- • Context-Aware Protection: Unlike traditional DLP, which relies on simple pattern matching, our DLP engine understands context for precise, consistent data security.
- • Seamless Responses: Once the LLM replies, redacted details are restored—ensuring clarity without compromising privacy.
- • Beyond NER & PII Protection: DLP doesn’t just detect names and identifiers—it understands and safeguards sensitive business strategies, trade secrets, and proprietary insights from exposure.
AI-Driven DLP: Smarter Than Traditional DLP
Why It’s Different
2. Privately Hosted LLM with End-to-End Encryption
For complete data control, our privately hosted LLM ensures full ownership and security.
- • BYOK Encryption: You hold the keys—only authorized users can access logs and data.
- • End-to-End Security: Every interaction is encrypted, ensuring only you can see conversation history.
- • Seamless Responses: Once the LLM replies, redacted details are restored—ensuring clarity without compromising privacy.
- • Document & PDF Processing: Summarize, extract insights, and process data securely.
- • Code Generation & Analysis: Enable safe code development without IP risks.
Secure, Flexible Use Cases
3. Build Secure AI Assistants with Wald.ai
Wald.ai enables businesses to build custom AI assistants tailored to their workflows—while ensuring zero data exposure and full compliance with industry regulations like HIPAA, SOC 2, and GDPR.
- • Secure by Design – End-to-end encryption and strict access controls.
- • Custom AI Solutions – Train AI on internal data for precise insights.

How does Wald’s PrivateGPT work?
Wald’s PrivateGPT i.e. Contextual Data Redaction is an advanced approach to protecting sensitive information in conversational AI systems. Unlike traditional methods, our technology understands the context and semantics of conversations, providing dynamic and intelligent protection.
Here's how Wald's Contextual Redaction works:
Detecting Sensitive Intent, Not Just Entities
At Wald.ai, we don’t just detect sensitive entities—we recognize sensitive intent. Even when a prompt doesn’t include personally identifiable information (PII), it can still convey highly sensitive situations. In many cases, the sensitivity lies in the context, not just in specific details.
Confidential AI Queries
Our Private GPT identifies and protects implicit sensitivity by applying inflection—a process that reframes prompts to maintain privacy while preserving their intent. Original Prompt(Sensitive Intent) |  Inflected Prompt(Protected Identity) |
 My manager sexually harassed me. How do I report this to HR? |  Someone’s manager sexually harassed them. How do they report this to HR? |
A colleague keeps making inappropriate jokes that make me uncomfortable, but I don’t want to escalate things unnecessarily. How can I address this through email in a firm yet professional way? | A colleague keeps making inappropriate jokes that make someone uncomfortable, but they don’t want to escalate things unnecessarily. How can they address this through email in a firm yet professional way? |
Why This Matters?
With Wald.ai's Private GPT, organizations can focus on productivity without compromising user privacy—ensuring security, trust, and ethical AI adoption.
Privacy First
Protects individuals by ensuring AI never processes personally sensitive information.
Ethical AI Use
Enables enterprises to leverage AI securely, without risking exposure of confidential matters.
Here's how Wald protects you...
Intelligent Context Analysis
Our advanced Natural Language Processing (NLP) engine comprehends the nuances of language, identifying sensitive information that traditional systems might overlook.
Adaptive Learning for Evolving Threats
Powered by our machine learning core, we adapt to new data patterns and potential vulnerabilities, keeping you ahead of emerging threats.
Comprehensive Data Relationships
By leveraging a Knowledge Graph, we map relationships between diverse pieces of information, enabling context-aware decisions about what requires protection.
Mathematically Guaranteed Privacy
Our Cryptographic Privacy Layer ensures that any sensitive information we store on behalf of our customers is kept encrypted with keys that they own, such that even we can’t access this data. This ensures that even if our servers are breached, the customer information stays safe.
Anonymized Learning on Sanitized Data
We ensure that any improvements to our sanitization models and fine-tuning occur only on anonymized and cleansed data—the same sanitized content sent to external LLMs. Since we never have access to sensitive data, there's no risk of it being used for training purposes.
