Red Sift
Red Sift is on a mission to make the internet fundamentally safer. Founded in 2015 and headquartered in London with teams across North America, Australia, and Spain, we build cybersecurity products that give security and IT teams real control over their email, domain, brand, and certificate security.
Our platform, Red Sift Pulse, brings together four integrated solutions: OnDMARC, Brand Trust, Certificates, and ASM. Instead of treating each attack surface in isolation, Pulse shares intelligence across products so teams get a unified, continuously updated picture of where they're exposed and what to do about it.
OnDMARC is our flagship product and the #1-rated DMARC solution in EMEA and Europe on G2. It automates SPF, DKIM, DMARC, BIMI, and MTA-STS, so even resource-constrained teams can achieve full DMARC enforcement without requiring deep email authentication expertise.
Brand Trust finds lookalike domains and phishing sites impersonating your brand across the web, using AI to classify and prioritize threats before they reach your customers.
Certificates monitors TLS certificates across your owned and third-party infrastructure (including private PKI environments) with real-time alerts before expiry or misconfiguration causes an incident.
Red Sift ASM (formerly Hardenize) continuously discovers and inventories your external-facing cloud assets and monitors them for misconfigurations before attackers strike. Unlike most ASM tools that stop at port scanning, Red Sift ASM goes deeper into protocol-level security, covering email, TLS, DNS, and cloud environments across AWS, GCP, and Azure.
Over 1,000 organizations trust Red Sift, including Domino's, ZoomInfo, TalkTalk, Pipedrive, and Save the Children. We're a recognized partner of Microsoft, Cisco, and Entrust, and were named the UK's 24th fastest-growing technology company by Deloitte.
