Email remains an essential communication channel for businesses worldwide, playing a critical role in marketing, customer engagement, and internal collaboration. Despite the rise of instant messaging and social media platforms, email continues to be the backbone of professional communication, handling over 300 billion messages daily as of 2023. However, the mechanics behind reliable email delivery are complex and involve multiple operational layers. Ensuring that an email arrives promptly, intact, and securely requires a deep understanding of protocols, infrastructure, and cybersecurity measures.
Your website is the place prospects decide whether you feel credible, customers decide whether you feel current, and partners decide whether you feel easy to work with. If publishing a new page still requires a ticket, a developer handoff, and a quiet prayer that nothing breaks, your CMS is charging you interest every week.
Email security threats continue to evolve, making strong authentication more important than ever. One of the most effective ways to protect your domain from spoofing and phishing attacks is by implementing DomainKeys Identified Mail (DKIM). By adding a DKIM record in your DNS, you create a digital signature that verifies your outgoing emails are genuinely sent from your domain and have not been altered in transit.
Here are the top 4 recent cyber incidents that kept the security experts on their toes. The renowned medical equipment manufacturer UFP Technologies was targeted by threat actors. On Wednesday, Olympique de Marseille experienced a cyber mishap, after which the authorities decided to reissue e-tickets. Meanwhile, there has been a sudden spike in phishing attacks on UK organizations. Also, a group of cybercrooks is using @google.com to run a new phishing campaign.
Deploying DMARC the right way: Here’s what MSPs and enterprises should know
by DuoCircle
On the surface, DMARC deployment is simple. In theory, all it requires you to do is publish a DNS record and enable monitoring—that’s all. But in reality, this approach does not really work for MSPs and enterprises. The entire purpose of implementing DMARC is negated if the authentication protocol is stuck at “p=none” for your email-sending domain.
When a DMARC failure hits production, act methodically. The fastest path to restore email authentication, protect domain security, and recover email deliverability is a repeatable DMARC troubleshooting workflow that isolates alignment issues, fixes misconfigured signatures, and eliminates unauthorized sending sources without disrupting business email.
Business email compromise remains one of the most costly advanced threats because it exploits trust, targets finance workflows, and evades traditional malware detection. A Zero Trust approach in Microsoft 365 applies “assume breach,” continuous verification, and least privilege to email security, collaboration tools, and mail flow.
Email spoofing and phishing attacks continue to target businesses of all sizes, making domain protection more critical than ever. A DMARC spoofing visibility report helps organizations see who is sending emails on their behalf, identify unauthorized sources, and understand how their domain is being misused.
