SAN FRANCISCO — October 29, 2026 — Nightfall AI, the AI-native data security platform, today announced that one of South Korea's leading digital financial services groups has selected Nightfall to protect sensitive data across its collaboration tools. The deployment covers about 4,000 employees across the group and its subsidiaries.
The customer runs consumer banking, payments and other financial services through a single mobile platform used by millions of people. Its employees work in Slack, Notion and Google Drive every day. Nightfall will find and stop sensitive data, such as customer financial records, personal information and credentials, from moving where it should not across those tools.
The customer chose Nightfall after a full proof of value and a formal RFP. Before purchase, Nightfall completed the customer's bank-grade cloud service provider safety assessment. The review covered 64 items across 11 sections, plus a penetration test annex, and went to the customer's Information Security Committee for approval.
"Banks and fintechs carry some of the most sensitive data there is, and their regulators expect proof, not promises," said Rohan Sathe, co-founder and CEO of Nightfall AI. "Passing a bank's full security review and earning a place across thousands of employees' daily tools says our approach works in the most demanding environments. Korea is one of the most advanced digital finance markets in the world, and we are proud to be here."
The deal was led by Nightfall's Korean managed security services partner. The partner ran the proof of value, the RFP response and the security review with the customer. Nightfall supported with fast technical and compliance answers on its detection engine, SaaS architecture and security commitments.
The win marks Nightfall's growing presence in Asia-Pacific through its channel program. It follows Nightfall's record fiscal second quarter, in which new business grew 241% year over year.
