Sendmarc

Sendmarc is a cybersecurity company headquartered in Cape Town, South Africa, founded in 2018. It builds DMARC (Domain-based Message Authentication, Reporting, and Conformance) email security solutions that protect organisations from phishing, spoofing and impersonation attacks by securing their email domains. The company serves enterprises, governments and small and medium businesses worldwide.

Its core product, the DMARC Management Platform, simplifies the configuration, monitoring and enforcement of email authentication protocols including SPF and DKIM. The platform provides real-time insights, policy enforcement and proactive threat detection. In 2023 Sendmarc expanded its portfolio with two products: Breach Detection, which monitors for stolen credentials, and Lookalike Domain Defense, which detects copycat domains.

Technically, the work spans email authentication protocols, threat detection, and phishing, spoofing and impersonation prevention. Sendmarc operates a partner-first model, equipping managed service providers, value-added resellers and OEMs with tools and expertise to deliver email security to their own clients. The company describes its mission as making the internet a safer place, having been founded out of a shared desire to protect email recipients from fraudsters impersonating trusted domains.
