DMARC reporting: When to enable it and how to address privacy concerns
by DuoCircle
DMARC reports are an essential aspect of your email authentication setup. Unlike what most organizations think, DMARC is not a one-time stint that you can implement and forget about. To get the most out of the authentication protocol and properly protect your domain, you must stay on top of things and monitor what’s going on in your domain.
When DKIM is not properly aligned for your domain, your outgoing emails may be at risk of tampering. That means anyone can make unauthorized changes to your email while it’s on the way to the receiver’s inbox, and the recipient might never even know it was altered.

DMARC for GDPR and data privacy compliance: Why email authentication matters for protecting PII?
by DuoCircle
When it comes to data privacy, the GDPR is clear about its goal: it wants organizations to protect personally identifiable information (PII) at every stage of processing and communication. And as you already know, DMARC is a mailbox gatekeeper that authenticates emails and prevents threat actors from misusing your domain.
Understanding all the elements of a valid DMARC record
by DuoCircle
DMARC prevents threat actors from impersonating you or someone from your organization and sending spoofed emails on your behalf. However, it’s not easy to set up, manage, and adjust DMARC to ensure this prevention. One of the challenging aspects of DMARC is understanding the syntax and its use case scenarios; otherwise, your DMARC record can run into errors.
If you’ve ever dealt with email security, chances are you’ve heard of DMARC—short for Domain-based Message Authentication, Reporting & Conformance. But what exactly does it do, and why should you care? Well, imagine your email domain is your digital storefront, bustling with clients and sensitive communications. Without proper email authentication, it’s like leaving your front door wide open to spoofers and phishers who can impersonate your brand, wreak havoc, and tank your email domain reputation.
DMARC alignment basics: Ensuring SPF and DKIM work together
by DuoCircle
DMARC alignment is the final checkpoint that ensures SPF and DKIM are not present for the sake of it, but are actually configured correctly and linked to your sending domain. This is done by verifying that the domain in the email’s visible ‘From’ address matches (or is aligned with) the domains used in SPF and/or DKIM authentication.

How can the finance sector leverage DMARC to defend against email fraud?
by DuoCircle
The finance sector thrives on trust. The fact that your clients are putting their hard-earned money in your company or institution shows that they not only have confidence in your financial products or services, but also that they believe you have the ability to keep their assets and data safe. But, truth be told, their money and data aren’t really safe unless you actively protect them.
How do third-party marketing agencies send emails on behalf of clients while staying

Using the DMARC reject policy for non email sending domains: A guide
by DuoCircle
You might think that only your active domain (the one that you use to send emails) is vulnerable to spoofing and phishing attacks. But the truth is, there is more than one way that attackers use to intercept your systems, and often they are the ones you least expect. That’s the reality of email-based attacks; they not only exploit your primary, active domain, but also make backdoor entries through non-email-sending domains and parked domains. The reason cybercriminals go after the parked domains, instead of active ones, is that the former are often overlooked. It is easier to think that the attackers might not even pay heed to the inactive ones, but they know that these dormant ones are low-hanging fruit.
