Sendmarc

DMARC management platform getting domains to email authentication enforcement quickly.

Sendmarc automates the path to DMARC enforcement, stopping attackers from sending email that impersonates a company's domains. The platform handles SPF and DKIM alignment across email sources and keeps monitoring after enforcement is reached. Founded in 2018 in South Africa, it sells directly and through MSPs managing many customer domains.
