ProDMARC
PROGIST
$100 per yearCybercriminals often employ forged emails to deceive both your customers and employees into revealing their login credentials. They may also send counterfeit invoices to your business partners and suppliers, creating further chaos. Additionally, these malicious actors distribute harmful emails that contain malware, such as ransomware, which can severely impact your organization. Furthermore, they utilize email spoofing techniques to sell illicit products, including weapons and drugs, while masquerading as reputable brands. To combat these threats, DMARC serves as an email validation protocol that hinges on two widely recognized authentication methods, SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail). SPF functions by allowing the recipient's mail server to verify whether the email sender's server is permitted to dispatch emails on behalf of the organization, thereby enhancing security. Meanwhile, DKIM employs a cryptographic method that utilizes both public and private keys to authenticate messages, ensuring their integrity during transmission from sender to recipient mail servers. Implementing these protocols is crucial in safeguarding against email-based attacks. -

DMARCLY
DMARCLY
$14.99 per monthPreventing threats such as phishing, business email compromise, ransomware, and spam is crucial, as is enhancing email deliverability. While DMARC primarily focuses on email security, its impact on email deliverability cannot be overlooked. By effectively preventing email spoofing, user engagement rises, leading to an improved domain sender score. A higher domain sender score translates to better email deliverability, ensuring that your business communications are more likely to arrive in recipients' inboxes. Successful email authentication is a key factor in achieving reliable email deliverability. Have you considered whether your emails are authenticated and reaching their destinations properly? With DMARCLY reporting, you can maintain confidence in your email deliverability. Understanding that your legitimate messages successfully land in inboxes while others do not provides marketers with reassurance. The principle of "no auth, no entry" is becoming increasingly relevant, as email service providers like Gmail and Office 365 are more frequently relegating unauthenticated emails to spam or rejecting them entirely. DMARCLY offers a robust solution for monitoring SPF, DKIM, and DMARC, ensuring your email practices are both secure and effective. This comprehensive approach not only protects your brand but also enhances your overall communication strategy. -
