Carrefour Enhances Cybersecurity With Corelight

In the fast-paced world of retail, implementing robust cybersecurity measures is not just a necessity but a critical element of operational success. Carrefour, one of the world’s largest retail groups, faced the daunting challenge of securing its expansive network infrastructure against increasingly sophisticated cyber threats.

Carrefour's digital transformation initiatives led to an expanded digital footprint, which, while beneficial for business operations, also increased vulnerability to cyber attacks. The retail giant needed a solution that could provide comprehensive visibility across its entire network, quickly detect malicious activities, and facilitate rapid response to threats. The existing security measures were insufficient to cope with the scale and complexity of Carrefour’s network, which spans numerous locations and serves millions of customers.

Corelight's network detection and response solution emerged as the ideal choice for Carrefour. Corelight leverages the power of open-source Zeek (formerly known as Bro), a powerful network monitoring framework that provides deep insights into network traffic. By implementing Corelight, Carrefour aimed to achieve enhanced network visibility, advanced threat detection and rapid incident response. Corelight’s unparalleled visibility into network traffic enabled Carrefour to monitor all data flows across its infrastructure. This comprehensive view is crucial for identifying potential security threats that might otherwise go unnoticed.

Corelight's ability to detect a wide range of threats, from malware and ransomware to more sophisticated, targeted attacks, was a significant factor in Carrefour’s selection process. The solution uses advanced analytics and machine learning to identify abnormal patterns and potential threats in real time. With Corelight, Carrefour can respond to incidents faster and more effectively. The detailed logs and metadata generated by Corelight streamline the investigation process, enabling security teams to quickly understand the nature of an attack and take appropriate action.

The deployment of Corelight’s solution at Carrefour involved deploying sensors across critical points in the network to capture and analyze traffic data. This deployment was seamless, thanks to Corelight's flexible architecture and compatibility with existing security tools. Post-deployment, Carrefour experienced a significant improvement in its cybersecurity posture. The key benefits included improved detection capabilities, operational efficiency, and scalability. The ability to detect and mitigate threats before they could impact operations, streamlined security operations, kept Carrefour’s security team from getting bogged down researching false positives and helped them to focus on more strategic tasks. Corelight's solution scaled easily with Carrefour's network expansion, ensuring continuous protection without additional complexity.

Carrefour's partnership with Corelight highlights the importance of advanced network detection and response solutions in modern cybersecurity strategies. By leveraging Corelight’s capabilities, Carrefour not only strengthened its defense mechanisms but also ensured a secure environment for its customers and business operations.

In an era where cyber threats are constantly evolving, Carrefour's proactive approach serves as a model for other organizations aiming to bolster their cybersecurity frameworks. With Corelight, Carrefour has not just met its current security needs but has also built a robust foundation to tackle future challenges.
