What the company sells

Red Sift helps security and IT teams embrace the security protocols that keep the internet safe, such as DMARC, SPF, DKIM and TLS. Red Sift says it is creating a fundamentally safer internet through proactive security across email, web and PKI.

Red Sift OnDMARC is the company's email authentication product. Red Sift says OnDMARC gives instant visibility into a domain's email security posture and a clear path to DMARC enforcement. Red Sift says OnDMARC helps organizations reach full DMARC enforcement in just 6 to 8 weeks. OnDMARC lets customers configure SPF, DKIM, DMARC, BIMI and MTA-STS in one place. Red Sift OnDMARC includes integrated VMC provisioning to simplify BIMI adoption.

Red Sift Radar is part of the OnDMARC offering. Red Sift says Radar pinpoints the root cause of issues like misaligned SPF records or unauthorized IPs. DNS Guardian provides continuous monitoring of DNS configuration to prevent SubdoMailing, dangling DNS and CNAME takeovers.

Red Sift describes it as detecting, monitoring and taking down malicious lookalikes with AI-powered domain and brand protection. Red Sift says Brand Trust can scan up to 150 million domains daily. Brand Trust lets teams issue takedown packages, escalate to enforcement bodies, or integrate intelligence into a SIEM and SOC. Social Media Monitoring in Brand Trust detects and removes fake profiles across Facebook, Instagram, X, TikTok, YouTube and LinkedIn.

Red Sift describes the problem it addresses as impersonation attacks against a brand. Its pages say that without DMARC, attackers can send spoofed emails from a domain to customers' inboxes, and that lookalike domains and phishing websites can be used to scam customers. Red Sift says it helps resource constrained security and IT teams reach DMARC enforcement in just 6-8 weeks.

Red Sift names customers across several sectors. Red Sift also publishes guidance aimed at healthcare organizations and at MSPs offering DMARC services.

Red Sift says it works across EMEA, APAC and the US. Red Sift says it has team members in 18 countries. Red Sift's homepage refers to 1,500+ security teams that choose it.[1][7][8][9][10][11][12][13][14][16][17]
