We are a team of privacy engineers, data scientists, and security experts on a mission to help every team find and protect sensitive data wherever it hides. We build the detection layer that tells you exactly what personal information lives in your text, documents, logs, and pipelines — so you can protect it before it becomes a liability.
You cannot protect data you cannot see. Every compliance program, every DLP policy, and every LLM guardrail starts with the same question: where is the sensitive data? At PII Detection API, our mission is to answer that question accurately, instantly, and at any scale — so teams can protect what they find.
We founded PII Detection API with a simple but powerful vision: every organization, regardless of size or technical expertise, should have access to enterprise-grade PII detection. Discovering personal data, protected health information, cardholder data, and leaked credentials should not require a dedicated data science team. It should be as accessible as sending an API request and reading back structured entities with offsets and confidence scores.
Our platform scans billions of data points daily, detecting and classifying more than 150 entity types across 60+ languages with industry-leading accuracy. From healthcare providers locating PHI for HIPAA compliance to financial institutions mapping personal data for GDPR, our detection engine powers data discovery across every industry. We measure our success not just in the entities we detect, but in the trust we enable between organizations and the individuals whose information they handle.
Explore Our APIFrom a research project in privacy-preserving machine learning to a global sensitive data discovery platform, our journey has been driven by a commitment to making PII detection accessible and effective.
Our founders, while working on privacy-preserving machine learning research, realized that existing PII discovery tools were either too complex for practical use or relied on brittle regex patterns that missed most real-world personal data. They set out to build something better.
We launched our first public API with support for 15 PII entity types, character offsets, and confidence scores. Within months, we had our first 100 paying customers, validating the market need for accessible PII detection.
We introduced our transformer-based named entity recognition models, dramatically improving accuracy from 85% to 97%. This breakthrough enabled context-aware detection that traditional regex approaches simply cannot achieve.
Secured GDPR-native certification and launched our enterprise tier. Signed our first Fortune 500 customer and expanded our team to 30 people across engineering, security, and customer success.
Expanded beyond plain text to detect sensitive data in documents, images (via OCR), audio transcripts, and video. We also grew the entity catalog past 100 types, adding credentials, secrets, and cloud keys alongside classic PII and PHI.
Launched support for 60+ languages and opened regional data centers in Europe and Asia-Pacific to meet data residency requirements. Reached 150+ detectable entity types.
Continuing to push the boundaries of detection technology with real-time LLM guardrails, streaming pipeline integrations, and ever-deeper entity coverage — so no sensitive data slips through unnoticed.
Our values aren't just words on a wall. They guide every decision we make, from product design to customer interactions.
We believe privacy is a fundamental human right. Every feature we build, every algorithm we design, starts with the question: "Does this protect user privacy?" We never compromise on security, and we practice what we preach by minimizing our own data collection and retention. Our systems are designed so that even we cannot access customer data in plaintext.
In PII detection, close enough isn't good enough. A single missed SSN or undetected name can mean a compliance violation or privacy breach. We obsess over precision and recall, continuously improving our models and testing against real-world edge cases. Our 99.9% accuracy rate isn't a marketing number, it's a commitment we measure and publish monthly.
Our success is measured by our customers' success. We don't just sell software, we partner with organizations to solve their privacy challenges. Our customer success team includes former compliance officers, security engineers, and data scientists who understand the real-world challenges our customers face. When you succeed, we succeed.
The privacy landscape evolves constantly. New regulations emerge, new data types appear, and new threats surface. We invest heavily in R&D to stay ahead of these changes. Our research team publishes papers, contributes to open-source projects, and collaborates with academic institutions to push the boundaries of what's possible in privacy technology.
Privacy protection shouldn't require a PhD in data science or a Fortune 500 budget. We design our products to be intuitive enough for a startup founder to implement in an afternoon, yet powerful enough for the most demanding enterprise use cases. Our free tier ensures that even the smallest organizations can protect their users' data.
Privacy regulations vary by region, but the need for protection is universal. We detect PII in 60+ languages, understand regional compliance requirements, and maintain data centers across multiple continents. Our diverse team brings perspectives from around the world, ensuring our detection models work for customers regardless of their location.
Our platform is engineered from the ground up for enterprise-scale workloads. The architecture combines transformer-based machine learning with robust, battle-tested infrastructure to deliver consistent performance regardless of volume. Whether you're scanning a single document or millions of records per hour, our API returns structured detections in milliseconds.
Transformer NER Models: Our named entity recognition models are trained on billions of documents across dozens of industries and languages. Unlike rule-based systems that rely on patterns, our models understand context. They know that "Dr. Smith" is a person while "a blacksmith" is a profession, and they can identify sensitive information even when it doesn't match expected formats.
Specialized Validators: Neural detection is paired with entity-specific validators — Luhn checks for credit card numbers, structural validation for IBANs and routing numbers, checksum and format rules for national IDs, and entropy analysis for API keys and secrets. This hybrid approach keeps false positives low while catching identifiers that context alone would miss.
Real-Time & Flexible Deployment: Our streaming architecture enables real-time detection in live data feeds — customer support chats, call center transcripts, and event pipelines — with sub-100ms latency. Use our cloud API for instant scalability, or deploy on-premises for maximum control over your data.
