This case study outlines the security transformation undertaken by Q2, a digital banking platform provider, as it sought to modernize its security operations in response to evolving threats and a growing cloud architecture. Q2 partnered with SentinelOne to implement an AI-powered security solution that significantly reduced malicious sessions by 97%. The document details Q2's transition from a legacy endpoint detection and response (EDR) solution to SentinelOne's Singularity Platform, which provides real-time threat detection and automated response capabilities across its endpoints and cloud workloads. It also highlights the integration of additional services such as Vigilance MDR and Purple AI to enhance incident response and operational efficiency. The results indicate a substantial decrease in attack volume and improved performance, allowing Q2 to maintain high standards of security and reliability for its customers. Overall, the case study presents a comprehensive view of Q2's strategic approach to building a future-ready security architecture.
