dmarcian and GreatHorn Partner to Protect Enterprises Against Impersonation Attacks, Credential Theft, and Business Services Spoofing

DMARC Domain Protection and Automated Email Threat Detection, Remediation, and Incident Response Solutions Allow Businesses to Email with Confidence

GreatHorn + dmarcian logosWaltham, MA and Brevard, NC – October 30, 2018 – GreatHorn, the leading cloud-native email security provider, and dmarcian, a company dedicated to making DMARC accessible to all businesses, have announced a new partnership dedicated to helping organizations protect themselves from and prevent phishing attacks. By pairing dmarcian’s deep expertise implementing the DMARC standard with GreatHorn’s comprehensive, cloud-native, and award-winning email security platform, organizations can now proactively protect their brand, their assets, and their employees from today’s most sophisticated email security threats.

Since nearly half (45.8 percent) of business professionals actively see executive, internal, or external impersonations bypass their email security solutions, it’s not surprising that business email compromise and phishing account for 48 percent of 2017’s Internet crime losses. By working together, GreatHorn and dmarcian address both the inbound and outbound effects of impersonations and domain spoofs.

“Phishing is a critical industry challenge, and it is characterized by threat actors who are constantly evolving their tactics and procedures to bypass static perimeter defenses. As security professionals, we we need to evolve our thinking beyond simple blocking solutions,” said GreatHorn CEO Kevin O’Brien. “dmarcian’s foundational role in establishing the DMARC standard aligns perfectly with GreatHorn’s anti-phishing model, and with this new partnership, our combined approach will help organizations protect themselves and their brands even more comprehensively than ever before.”

DMARC is an important email security protocol that helps protect enterprises from phishing, social engineering, and other types of impersonation attacks. Nearly all federal government agencies adopted the email security protocol to comply with the Department of Homeland Security (DHS)’s 18-01 binding operational directive (BOD), but the private sector hasn’t followed suit. In fact, the 2017 Global Spear Phishing Report found that only 21 percent of companies had enabled DMARC. dmarcian’s SaaS platform provides IT and security teams with a summary of the status of all of the organization’s domains and sources to simplify compliance.

“Corporate email not only serves as a company’s lifeblood, but also as a brand ambassador as workers connect with the outside world,” said dmarcian CEO Tim Draegen. “Yet we have to recognize that universal deployment of DMARC will take years to achieve. That’s why it’s so critical for organizations to use GreatHorn to protect their email from external domain spoofs and impersonations, as well non-authentication-related threats.”

Security and IT leaders can learn more about how to combat the phishing threat in the upcoming joint webinar, “Beyond the Nigerian Prince: The Evolution of Phishing & How We Fight Against It”.
