Mimecast's industry-leading DMARC Analyzer allows organizations to publish DMARC records to help combat dangerous cyber attacks.
As the use of email spoofing continues to rise, more organizations are turning to DMARC protocols and publishing DMARC records to help combat this dangerous threat.
Email spoofing is a form of cybercrime where attackers send an email that appears to come from your organization. Spoofed emails may target your employees, customers, partners or suppliers. By impersonating a trusted source, attackers try to get the email recipient to reveal login credentials, share sensitive data, or transfer funds to a fraudulent account.
Email spoofing takes advantage of the fact that it's very easy to make an email appear to come from any address. DMARC, or Domain-based Message Authentication, Reporting & Conformance, is an email validation system that can help receiving organizations stop the delivery of spoofed emails and help sending organizations discover scammers who are using their domain without authorization.
When using the DMARC, an organization publishes a DMARC record that lets a receiving email server know what to do with messages that fail a DMARC test.
Though DMARC is a powerful tool for stopping email spoofing, it's also a challenge to deploy and manage. Without the right tools, it can be costly and time-consuming to establish DMARC policy enable email servers to perform a DMARC check. To simplify DMARC implementation, Mimecast provides an industry-leading solution in Mimecast DMARC Analyzer.
Mimecast DMARC analyzer is a cloud-based solution that enables rapid deployment of DMARC protocols and streamlined publishing of DMARC records. In contrast to other DMARC solutions that require professional services for successful implementation and management, DMARC analyzer offers self-service tools that simplify DMARC deployment and minimize the time, effort and cost of stopping domain spoofing attacks.
With DMARC analyzer, organizations can:
Mimecast DMARC Analyzer offers simple and effective self-service tools that enable email security teams to publish a DMARC record and deploy DMARC quickly and efficiently. DMARC analyzer provides:
Organizations can combine Mimecast DMARC Analyzer with additional Mimecast solutions for email security to stop email spoofing and other sophisticated email threats. Mimecast Email Security with Targeted Threat Protection offers a suite of solutions that include:
DMARC is the Domain-based Message Authentication, Reporting & Conformance protocol, a system for validating the authenticity of emails. DMARC builds on two widely used email authentication protocols – Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) – to help a receiving mail server judge whether an inbound message is legitimate.
DMARC record is a DNS text record that is published in a domain's DNS database. A DMARC record lets ISPs know if a domain is set up to use DMARC and lets receiving email servers know what the organization's DMARC policy is concerning messages that fail SPF or DKIM authentication. A DMARC record may specify that messages which fail to authenticate can be delivered in the inbox, sent to the spam folder or needs to be blocked.
A valid DMARC record is required when deploying DMARC. A DMARC record check is a diagnostic tool that parses a DMARC record and determines whether it is valid. Mimecast offers a free DMARC record check along with free SPF and DKIM checks.
