Nightfall AI has introduced “Firewall for AI,” a new security product aimed at protecting generative AI applications and data pipelines from sensitive data exposure and malicious prompt injections. The service, which ensures compliance with regulations like GDPR and CCPA, operates as a client wrapper that scans workflows to remove sensitive information and defend against attacks by detecting malicious content and maintaining data quality. Integrating seamlessly via APIs and SDKs, it enables real-time risk monitoring and mitigation. The startup, supported by investors like Bain Capital and actor Paul Rudd, raised $40 million in a Series B round in August 2022.
