Nightfall AI is a cloud data loss prevention platform that uses machine learning to detect and protect sensitive information — including PII, credentials, healthcare data, and financial records — across SaaS applications, cloud storage, and messaging tools. It scans Slack, Jira, Confluence, GitHub, Google Drive, and S3 in real-time, automatically redacting or alerting on sensitive data exposure. Security and compliance teams at fast-growing companies use Nightfall to achieve data security posture without slowing engineering teams down.
