Real-Time Frontend PII & Security Leak Detection

A lightweight JavaScript runtime agent that monitors your frontend for PII leaks, token exposure, risky data flows, runtime XSS behavior, and unauthorized exfiltration without breaking UX or slowing down your app.

What Privelo Monitors

Network Flow Visibility

Hooks fetch, XHR, WebSocket, and Beacon to detect PII in requests, responses, encoded payloads, and suspicious destinations.

DOM Exposure Detection

Monitors dangerous sinks such as innerHTML, insertAdjacentHTML and UI-rendered content to ensure sensitive data never appears where it shouldn’t.

Runtime XSS Sensor

Detects inline script injections, malicious eval usage, tainted dynamic scripts and suspicious client-side execution patterns.

Zero-Knowledge PII Detection

Identifies emails, tokens, secrets, IDs and personal data in motion sending only PII types, hashes and metadata to the backend. No raw data ever leaves the browser.

Optional ML Classification

Lightweight, client-side ML models analyze high-entropy strings and text snippets to detect secrets and sensitive patterns more accurately.

Policy & Blocking Engine

Dynamic policies from the backend control detection severity, sampling, whitelisted domains, and optional blocking mode for dangerous sinks.

ML-Powered Anomaly Detection

Backend machine learning models detect abnormal data flows, suspicious API behavior, and irregular payload structures.

Seamless SIEM Integration

Privelo generates structured, privacy-safe events ready for ingestion by all modern SIEM platforms. No raw PII, no noisy logs, and no complicated parsing just clean, security-focused insights that seamlessly integrate into your existing monitoring and alerting pipelines.

Native SIEM Compatibility

Export events directly to Splunk, Elastic, Sentinel, Datadog, QRadar, or any JSON-based SIEM.

Privacy-Safe Event Format

No raw PII or secrets are transmitted. Only hashes, field paths, severity levels, and metadata.

Unified Security Pipeline

Forward Privelo events into your central alerting pipeline to enrich threat detection and correlate potential exfiltration patterns across your stack.

How Privelo Works

Privelo doesn’t require installing anything on user devices. It runs as a lightweight JavaScript snippet placed directly in your web application, similar to how analytics tools integrate. No browser plugins, no desktop agents, no performance impact just simple, frictionless deployment

It analyzes application data flows using regex, heuristics, and optional ML, and emits privacy-preserving events containing only hashes, metadata, and PII categories but never raw user data.

Backend never receives raw user data only derived signals.

The Clear Conclusion

Backend masking protects data after it has already been collected.
Zero-knowledge ensures you never collect raw data in the first place.
