Red Sift

The Red Sift Pulse platform 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 the company's flagship DMARC solution. 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 brands across the web, using AI to classify and prioritize threats before they reach their customers.
• Certificates monitors TLS certificates across 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 external-facing cloud assets and monitors them for misconfigurations before attackers strike. Unlike 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.

The vendor states that over 1,000 organizations use Red Sift, including Domino's, ZoomInfo, TalkTalk, Pipedrive, and Save the Children. They further state that they are a recognized partner of Microsoft, Cisco, and Entrust, and were named the UK's 24th fastest-growing technology company by Deloitte.

Red Sift states its mission is to make a fundamentally safer internet. Founded in 2015 and headquartered in London with teams across North America, Australia, and Spain, the company builds cybersecurity products that give security and IT teams real control over their email, domain, brand, and certificate security.
