As Microsoft’s security capabilities continue to evolve, many organizations are questioning how much they should rely on Microsoft for their email security needs. In this guide, we observe where Microsoft may not be enough and how deploying Fortra Advanced Email Security solutions can provide a more comprehensive protection.
When it comes to email authentication standards, should you use DKIM, SPF, or both? We’re going to cover these terms, when you should use them, what they do—and how best to protect your email domains.

In this DKIM setup guide, we’ll walk you through the steps on how to set up DKIM correctly, test it, avoid common pitfalls, and fix common mistakes. In case you’re new to DKIM, or DomainKeys Identified Mail, we’ll start with a high-level overview before getting to the step-by-step instructions, but you can first look up your DKIM record here.
What is...
In 2021, Gartner includes DMARC, or known by its full name as Domain-based Message Authentication, Reporting & Conformance, in its list of top 10 security projects. With very few exceptions, the best way for organizations to prevent getting impersonated in email attacks is to integrate DMARC into their Office 365-based email ecosystems.
To understand why, let’s consider the benefits of deploying...
The secure email gateway no longer works for business email compromise and advanced email threats. Discover why you need the Fortra Advanced Email Security.

Office 365 phishing emails come in common patterns. I'll list them here and also cover Office 365 anti-phishing features for prevention, detection, and response.
Today, the typical Office 365 phishing emails direct users to fake Office 365 Sign-in pages. The victim submits their credentials, effectively handing over their password. Fraudsters use that login to access the victim’s address book,...
We'll cover what DKIM for email is, why your company needs it, how it works, how to set DKIM up, and additional ways to prevent email spoofing attacks.
What is DKIM?
First, let’s clarify what DKIM is in email. DomainKeys Identified Mail is a technique that uses your domain name to sign your emails with a digital “signature” so your customers know it’s really you sending those emails and that...
Amid a troubling rise in zero-day phishing attacks, recent research suggests that some companies may be making an ill-advised shift away from blocking advanced email threats to responding to them post-delivery. If true, the capitulation couldn't come at a worse time. Since January, cybercriminals taking advantage of the COVID-19 outbreak have been targeting businesses and individuals with an...

You already know that email is the number one attack vector for cybercriminals. But what you might not know is that without a standard email security protocol called Domain Message Authentication, Reporting, and Conformance (DMARC), your organization is open to the phishing attacks that...
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...
When you begin to work with DMARC, you realize just how important identifier alignment is. Identifier alignment forces the domains authenticated by SPF and DKIM to have a relationship to the "header From" domain. Header From Domain and the MailFrom domain are different?Yes, they are! Hearing these terms can confuse people. They sound like the same thing, but in reality they are not. The...
This is the second in a new ongoing series for us that gives you the tips and tricks you need for successful DMARC deployment . Read the previous tip here. DomainKeys Identified Mail (DKIM) is the successor to Yahoo DomainKeys. Both share similarities, however DKIM has the additional aspects of Cisco's Identified Internet Mail standard (IIM). The enhancements to this standard gives more security...
