About DLPVANSH

DLPVANSH is a free, open-access Data Loss Prevention (DLP) testing platform designed for information security professionals, IT administrators, and compliance teams. Our mission is to provide a simple, reliable, and vendor-neutral tool that helps organizations verify their DLP policies are working as intended.

Why We Built DLPVANSH

Testing DLP policies has traditionally been a cumbersome process. Security teams often need to set up dedicated test environments, configure custom endpoints, or rely on limited vendor-provided testing tools. Many existing DLP test sites are outdated, unreliable, or lack the flexibility to test different protocols, content types, and body formats.

DLPVANSH was created to fill this gap. We wanted to build a modern, always-available testing endpoint that lets security professionals quickly validate their DLP configurations without any setup overhead. Whether you need to test a simple text-based policy or verify that your DLP system correctly inspects multipart file uploads with specific MIME types, DLPVANSH handles it all from your browser.

What Makes DLPVANSH Different

Protocol Flexibility

Test across HTTP and HTTPS with granular control over body formats and MIME types. FTP and WebSocket support coming soon.

Real-Time Results

Instantly see whether your DLP blocked or allowed each test transmission, with per-file progress tracking for uploads.

EUN Verification

View the actual End User Notification pages your DLP system presents, helping you verify block page content and branding.

No Registration Required

Start testing immediately. No accounts, no sign-ups, no API keys. Just open the site and begin validating your policies.

Privacy Focused

Test payload data is never stored or logged. Your sensitive test data is processed in memory and immediately discarded.

Vendor Neutral

Works with any DLP solution that inspects web traffic — Zscaler, Symantec, Palo Alto, Forcepoint, Microsoft Purview, and more.

How It Works

DLPVANSH operates as a straightforward web application. When you submit a text payload or upload a file, the data is sent as an HTTP or HTTPS request to our server. The request passes through your organization's network, where your DLP system (whether it's a proxy, inline appliance, endpoint agent, or cloud-based service) has the opportunity to inspect the traffic.

If your DLP detects sensitive data in the payload and blocks the request, DLPVANSH reports the transmission as "BLOCKED." If the request reaches our server without interception, it's reported as "ALLOWED." This simple feedback loop lets you quickly iterate on your DLP policy configurations.

The testing tool gives you control over several parameters that affect how DLP systems inspect traffic:

Build Version History

VSQ_1.0326_PROD

MVP launch of dlpvansh.com. Basic website with HTTPS and HTTP POST testing for text payloads and file uploads. Single-part and multi-part body formats with configurable MIME types.

VSQ_2.3426_PROD

Major UI overhaul. Added sample data pages for PCI, GLBA, and HIPAA compliance testing. Introduced EUN (End User Notification) mode, dark theme, live visitor tracking, and admin dashboard.

VSQ_3.4426_PROD

Introduced GET request testing with two-column send/response layout. Added request timeouts (2 min), payload size limits (150 MB file, 10 MB text, 8 KB GET), and server-side protections.

VSQ_4.5426_PROD

Added user identification system. Name prompt on Test and Sample Data pages with personalized welcome display.

Introduced rate limiting to protect service stability — excessive requests from a single source are automatically throttled. Updated privacy policy.
