Integrated cybersecurity platform for digital resilience MoreLess
Red Sift is a cybersecurity startup that provides a platform for security teams to understand and mitigate cybersecurity risks before they become incidents. The company operates in the cybersecurity market, serving clients who need to protect their digital assets from threats such as phishing and BEC attacks.
Red Sift's business model revolves around its Red Sift Pulse platform, which uses artificial intelligence (AI) to analyze terabytes of cybersecurity intelligence data daily.

In addition to the Pulse platform, Red Sift offers other products such as OnDMARC for protection against phishing and BEC attacks, Brand Trust for brand impersonation discovery and monitoring, ASM for continuous attack surface management, and Certificates for continuous certificate discovery and monitoring.
Red Sift generates revenue by charging its clients for access to its platform and its suite of cybersecurity products. The company's solutions are designed to integrate seamlessly with existing tools, reducing the risk of disruption and making it easy for clients to start using them.
