Legacy DLP solutions have trouble differentiating between unauthorized and legitimate data transfers due to…
Nighfall for data at rest

Low accuracy

Legacy DLP solutions are notoriously noisy, and lead to a high volume of false positives.

Nightfall for SaaS

Complex workflows

Manual security workflows slow time to remediation, and put sensitive data at risk.

Nightfall for ChatGPT

Frequent interruptions

With low accuracy and slow time to remediation, legacy DLP solutions don’t just impact security team productivity, but also impede workflows company-wide.

Nightfall offers an automated, AI-powered solution
