What is Data Loss Prevention (DLP)?

DLP ensures confidential or sensitive information (like credit card and social security numbers) isn’t shared outside of Slack by scanning for content within messages and files that break predefined policies.

Does Slack have DLP functionality built-in?

No, Slack relies on third-party apps (like Nightfall) to provide DLP functionality in Slack.

How do I implement DLP on Slack?

Nightfall is a Slack bot so you can add it in seconds to your Slack workspace. No additional set up, tuning, or installed agents are required. Request a demo or free trial here.

How does Nightfall work?

Nightfall is a Slack bot that helps you discover, classify, and protect your sensitive data in Slack. Instantly add DLP and data classification functionality across your Slack workspace.

Our bot identifies business-critical data, customer PII (personally identifiable information, such as credit card numbers), and PHI (protected health information) across your Slack workspace, so you can manage & protect it.

Nightfall supports compliance efforts with PCI, GDPR, HIPAA, SOX, and various other regulatory regimes.

  • Discover: Continuously monitor sensitive data that is flowing into and out of files & messages in Slack.
  • Classify: Machine learning classifies your sensitive data & PII automatically, without prior tuning or tagging, so nothing gets missed.
  • Protect: Setup automated DLP workflows for quarantines, deletions, alerts, coaching, and more – saving you time and keeping your business safe.
