Protecto is a data security and privacy platform for AI agents and LLMs that detects, masks, and controls access to sensitive information (PII, PHI, confidential data) across 200+ data types in 50+ languages with 99.9% claimed detection accuracy. It is listed in the AI security category.
The platform sits between enterprise data and AI systems, detecting, masking, and controlling sensitive information access across AI interactions. What sets Protecto apart is context-based access control — making dynamic access decisions at the moment an AI agent requests data, not through static role assignments.
Protecto became available on Google Cloud Marketplace in March 2026, and reports protecting over 1 million AI interactions with zero data breaches across more than 3,000 companies. Customers include Inovalon, Automation Anywhere, Ivanti, Bank of Muscat, and Nokia.
What is Protecto?
Protecto tackles a specific problem in enterprise AI: sensitive data moves with AI context, and traditional security tools were not built for this. When an AI agent processes a customer query, it may access databases containing PII, PHI, financial records, and proprietary information. Protecto detects, masks, or controls that sensitive data based on who is asking, why, and in what context.
The key technical feature is format-preserving tokenization. When Protecto masks sensitive data, it keeps the semantic structure intact so AI models can still reason over the protected content. A masked social security number still looks like a number in the right format; a masked name still sits in the right position in a sentence. This avoids the accuracy degradation that simpler masking approaches cause.
Three products cover different aspects of AI data security: Privacy Vault scans, masks, and stores sensitive data; GPTGuard protects generative AI pipelines with masking and content filtering; and CBAC provides context-based access control for AI agents.

Privacy Vault
Privacy Vault is Protecto’s core data storage component. It scans data sources to discover sensitive information, masks it according to configured policies, and stores the mapping between original and masked values. When an authorized agent or user needs the real data, Privacy Vault handles unmasking based on CBAC policies.
The vault sits between your data stores and AI systems, so sensitive data never reaches the AI layer in its raw form unless access policies explicitly permit it.
GPTGuard
GPTGuard protects generative AI pipelines specifically. It intercepts prompts and responses flowing between users and LLMs, detecting and masking sensitive data in real time. Content filtering rules block prompts that attempt to extract protected information, while response filtering prevents the model from including sensitive data in its outputs.
Context-Based Access Control
CBAC is what separates Protecto from simpler masking tools. Traditional role-based access control assigns static permissions: an employee either has access to a data set or doesn’t. CBAC evaluates access dynamically when an AI agent requests data.
The decision factors include who is making the request, their role, the purpose of the query, and the operational context. A sales AI agent cannot access support ticket data even if the underlying system has access to both data sets. A support agent can see customer names but not payment details unless the query specifically requires billing resolution.
Getting Started
When to use Protecto
Protecto fits organizations where AI agents need access to sensitive enterprise data but the data itself must remain protected. This is the core tension in enterprise AI adoption: AI agents need context to be useful, but that context often contains PII, PHI, financial records, or proprietary information.
It is most relevant for healthcare organizations handling PHI, financial services companies dealing with regulated customer data, and any enterprise where AI agents serve multiple departments with different data access requirements. CBAC solves the problem of shared AI infrastructure accessing siloed data — something static RBAC handles poorly when AI agents cross organizational boundaries.
Format-preserving tokenization matters when data masking would otherwise break AI accuracy. Simple redaction (replacing PII with “[REDACTED]”) confuses language models. Protecto’s approach preserves the structure so the AI can still reason over the content.
