Mimecast DMARC Analyzer

Cybercriminals consistently take advantage of how easy it is to impersonate an organization’s email to dupe their customers, supply chain and even their own employees. Domain spoofing, where an attacker essentially forges your email to make it look as though their communication has come from a trusted source, is a common tactic used in phishing campaigns and business email compromise (BEC), the use of which grew by 54% and 67% respectively in the last 12 months alone[1]. It’s a big reason why email continues to be the tool of choice for cyber attackers.

Valimail Enforce

As DMARC continues to accelerate and Cloud IT becomes the norm with multiple third-party emailers sending on your behalf, email authentication is key to protecting your organization from impersonation attacks. Impersonation attacks prey on victims’ familiarity with your organization’s email domain and are much harder for end-users to detect. DNS was not built for modern authentication standards, however, and most organizations have found the authentication process difficult because it's not just a simple configuration project. Email authentication is an ongoing operational activity that must be maintained. Valimail Enforce was purpose-built to get organizations to enforcement with automation. That means your organization can be more secure with fewer vulnerabilities, and no DNS manual process. With Valimail Enforce, your employees, partners and brand are protected automatically.
