Sample Datasets

Use sample data sets provided by Nightfall to test Nightfall's detection capabilities.

The following datasets can be used to test Nightfall's advanced AI-based detection capabilities. The data has been fully de-identified and can be used to test any data loss prevention (DLP) platform.

PII Samples

This dataset showcases Nightfall’s ability to detect Personally Identifiable Information (PII) with exceptional precision and minimal noise across text, spreadsheets, and screenshots. Samples include names, U.S. social security numbers, driver's license numbers, and more. See Image ID Samples for image samples of driver licenses and other ID types.

Hi Support - My name is Julie Walsh. I tried to purchase a life insurance policy online yesterday however the site said, "an unexpected error occurred." I tried to pay with a credit card. My DOB is 02-10-97 and SSN is 523-23-6145. Could you take a look on your end?

PCI / Banking Samples

This sample dataset demonstrates Nightfall's ability to detect sensitive banking and payment information with high precision and low noise in text, spreadsheets, and screen grabs. Samples include positive and negative examples of credit card numbers, routing numbers, IBAN codes, and SWIFT codes.

Testing note: If a key status is marked as ‘Active’, please rotate the key immediately. Not all vendors provide an "Inactive" response code. In these cases or if the vendor service is offline, the finding status will be marked ‘Unverified’.

Password Samples

Nightfall AI detects passwords shared in conversational text and code.

PHI Samples

Nightfall’s PHI model surpasses traditional entity-based detectors by combining multiple signals — including PII and medical indicators — and analyzing their relationships and context to ensure only patient health–related content is flagged.

Image ID Samples

Nightfall’s computer vision (CV) transformer model outperforms legacy Optical Character Recognition (OCR) text scanning to identify driver’s licenses, passports, credit cards, and US social security cards even though images may be degraded (rotated, glossy, low contrast, blurry, skewed, or cropped).

File Classifier Examples

The File Classifier goes beyond entity detection by analyzing a document’s purpose, structure, format, and contextual signals to accurately identify intellectual property, proprietary source code, and other sensitive internal records. These examples demonstrate how the classifier protects confidential materials—including internal source code, legal and regulatory drafts, HR documents, and strategic planning files—across a wide range of real-world scenarios.
