CISA is investigating a significant data breach at Sisense, resulting in the theft of terabytes of customer data.

The breach affected over 2,000 Sisense customers, including notable firms like Nasdaq and Verizon, and critical infrastructure entities.

Sisense's CISO has recommended that customers reset any potentially compromised credentials following the breach.

The US government has warned all Sisense customers to change passwords, indicating a potential compromise of sensitive information.

Due to the breach, customers are also advised to change passwords for third-party services linked to Sisense, reset API keys, and monitor for suspicious activity since April 5.
