In today’s digital world, email remains one of the most powerful communication channels, but it is also one of the most abused. Every day, millions of malicious emails are sent to deceive recipients — from phishing to brand spoofing to targeted business email compromise (BEC). As these attacks evolve, so too must our defenses. At…
DMARC is important for protecting emails sent from G Suite (Google Workspace) because it verifies your domain’s messages via SPF/DKIM alignment and tells receiving servers to quarantine or reject spoofed mail, which dramatically reduces phishing while improving deliverability and visibility through standardized reporting. G Suite’s native security (SPF and DKIM) prevents many spoofing attempts, but…
Cybercriminals are getting smarter, quieter, and far more convincing. From a new browser-based ClickFix variant that slips past traditional security tools, to healthcare organizations facing legal action after phishing breaches, and even UK MPs being targeted through trusted messaging apps, recent incidents show how fast attack methods are evolving. These threats no longer rely on…
In today’s hyper-connected digital world, email remains the backbone of business communication — and unfortunately, also one of the most exploited attack vectors used by cybercriminals. Sophisticated threat actors continually refine their techniques to deceive trusted recipients, impersonate legitimate senders, and manipulate end users into disclosing sensitive information or transferring funds. At DMARCReport, we believe…
Yes—DMARC explicitly evaluates SPF and DKIM authentication results and verifies their alignment with the message’s Header From domain, passing if at least one of SPF or DKIM both authenticates and aligns per your DMARC policy. DMARC (Domain-based Message Authentication, Reporting, and Conformance) exists to connect message authentication to domain identity as shown to recipients: the…
As DNS users, domain administrators, and website operators know all too well: DNS configuration often feels like walking a tightrope. A small misconfiguration can mean your users can’t reach your site — or your email goes missing. Two DNS record types that are often sources of confusion are CNAME and ALIAS records. They can look…
By DMARCReport When you register a domain name — say mywebsite.com — you’re not done yet. To get the domain to actually load your website, or allow email to be delivered, you need to configure the Domain Name System (DNS) appropriately. Think of DNS as the internet’s “phone book.” Instead of human-readable domain names, computers…
Implement DMARC for multiple domains and subdomains by standardizing a DNS template (SPF, DKIM, DMARC), inventorying all sending services, using parent-level inheritance with the DMARC sp tag where appropriate, centralizing rua/ruf reporting, rolling out p=none then gradually enforcing per domain (quarantine → reject) based on report-driven confidence, automating DNS and DKIM key management via APIs/IaC,…
Introduction At DMARCReport, we’ve always believed that email authentication and brand trust should go hand in hand. That’s why the recent update from Google — enabling support for Common Mark Certificate (CMC) under Brand Indicators for Message Identification (BIMI) — is big news for businesses of all sizes. If you’re sending emails to clients, subscribers…
