Red Sift is a global cybersecurity company that provides proactive security solutions across email, web, and public key infrastructure (PKI). The company operates across EMEA, APAC, and the United States, offering regional expertise to protect organizations and their customers. The company's flagship product, OnDMARC, focuses on email authentication and DMARC implementation to prevent email-based attacks and domain spoofing. Red Sift also operates Hardenize and SSL Labs, tools that help organizations secure their websites through SSL/TLS and PKI security assessments. The company emphasizes ensuring that security standards like DMARC and TLS are properly implemented and maintained over time. Red Sift's approach centers on four key principles: embracing security protocols and ensuring correct implementation, protecting known gaps that can be exploited even when protocols are fully deployed, preventing security drift to maintain effective protection, and using AI to scale security operations for global teams. The company was co-founded by Rahul Powar (CEO), who previously worked as principal technical architect at Shazam and founded Apsmart, and Randal Pinto (CTO), who also has a background at Shazam. Ivan Ristic serves as Chief Scientist and is known for creating ModSecurity and authoring "Bulletproof TLS and PKI." Red Sift completed a $54 million Series B funding round in January 2022.
