The Email Authentication Challenge
Email is the #1 way attackers target an organization’s customers and email ecosystem. DMARC authentication, specifically with an enforcement policy of Reject, is the single most effective way to close this vulnerability inherent to email. While the premise of authentication is straightforward, organizations can encounter roadblocks and challenges along the way...

Email is a primary vector for attacks on your business today—and email threats are evolving faster than ever. But actionable data about email attacks is often inaccessible to time-strapped security operations and incident response teams. That disconnect leaves your business vulnerable and unable to mitigate hidden email threats.

Enterprise email architecture is evolving, which is good news for cybercriminals. Legacy secure email gateways (SEGs) simply don't provide full protection from today’s evolving and costly attacks, and cloud-based email requires a new security approach. In contrast, the next generation of email security—the AI-powered Secure Email Cloud—gives organizations more comprehensive security and better...

In the last five years, we’ve all become far too familiar with it – hackers spoofing a company’s domain and therefore tarnishing the brand, bad actors attempting to infect our computers with malware, and criminals sending millions of spam messages.
As if this isn’t enough, now there is a whole group of people working to outsmart companies AND their customers by using cousin domains to fool...
This is the start of a new ongoing series for us that gives you the tips and tricks you need for successful DMARC deployment.What does "PermError SPF Permanent Error: Too many DNS lookups" mean?There are several safeguards put in place with SPF. One of these is a limitation of DNS lookups to help ensure that you do not have timeout issues. SPF will evaluate only 10 DNS mechanism lookups in an SPF...
The Benefits of Monitor Mode
When a technology exists that can tell you if and when your domains are being spoofed (and by who), why would you not use it?!
What is DMARC?
DMARC was created to address some fundamental problems with existing email authentication technologies (SPF and DKIM). It provides feedback about your email authentication implementation and gives ISPs (Google, Yahoo!,...
