Without inputting your own Nightfall API key, this free utility will have the following limitations: up to 500 items (e.g. files) or 500 MB of data will be scanned, and the first 100 sensitive findings will be outputted in the report.
These limitations don't apply if you input your own Nightfall API key, so we highly recommend doing so. In other words, with your own API key, you'll be able to run a complete scan. You can create an API key on your Nightfall Dashboard.
If you don't have an account to create an API key, you can sign up for the Nightfall Developer Platform for free (no credit card required). Learn more about the Developer Platform in the API Docs.
The max size for individual files for this scanner is 20 MB. The service may filter high volumes of noise in the event that your detection rules may benefit from further tuning, and scans may terminate early if they are generating a very high volume of results, so that you can fine tune your detection rules prior to re-running the scan and consuming data volume. Similarly, results may be truncated to respect the max file size of email attachments and so files are openable.
Please email us or schedule a meeting if you have any questions.
