SC Labs product reviews: Email security

Editor’s Note: This set of reviews originally appeared in February 2020. To find out more about SC Labs, contact Adrian Sanabria at [email protected]

The use of collaborative tools and technologies is on the rise with email topping the list. That explains why it faces such relentless attacks. Email communications are leveraged to keep businesses running efficiently, but unfortunately, is often overlooked when it comes to implementing adequate security measures. Tools in the past have focused mainly on spam protection. However, we have recently seen impressive expansion in what these solutions offer. From advanced threat protection and encryption to machine learning and computer vision, email security has come a long way.

Timely and accurate
detection of suspicious email content is crucial but security doesn’t end
there. Even with sophisticated security tools, there is no 100 percent
guaranteed solution. Therefore, malicious items are going to make their way
into inboxes, and employees need to be prepared. Many of the solutions we
looked at this month recognize the importance of employee awareness and have
built-in training with real-world practices and customizable campaigns. Some
solutions even offer pre-delivery malicious email prevention, but we have yet
to find an impenetrable email security shield.

of the primary entry points for malware, which can be devastating, is email.
Therefore, finding an effective email security solution should be at the top of
every information security to-do list. The tools we looked at this month go a
long way in meeting these email security demands.

Email security

As the SC Labs team
revisited the email security space we were happy to see some familiar players
and excited to be introduced to new names. These email security solutions
protect on-premise exchange servers, Office 365 Exchange Online and G-Suite
Gmail for business solutions. The use of all collaboration technologies is
exponentially increasing; this especially true for email. Finding an effective
email security solution, therefore, should be at the top of every information
security team’s to-do list.

security has evolved from simply spam protection and email encryption of
on-premises exchange servers. Last year, the industry began integrating in
earnest with cloud platforms, and now, cloud integration seems to be a standard

year, we saw a lot of exciting new features, including automation through
machine learning, full end-to-end encryption of inbound and outbound
communications, impersonation protection and sandbox analysis.

incorporation of machine learning and artificial intelligence to this space
seemed to be a natural next step. Machine learning technologies can now not
only learn expected user behaviors but also analyze, detect, and respond to
threats, a remarkable development to say the least. By learning from expected
user behaviors, anomalous behavior is flagged and further investigated,
dramatically increasing detection capabilities. In some cases, we even saw
computer vision leveraged first to detect HTML changes or slight variations
from trusted sites then to classify such pages as spoofed or unsafe. With some
machine learning technologies capable of acting on threats in under a second,
security teams and administrators are free to focus on other critical or
complex items that require human analysis.

Although there is no 100 percent secure and fool-proof way to protect email communications, these solutions continue to advance with innovations and protective measures. A seatbelt is not guaranteed to save lives in every single accident, but it certainly adds significant protection to the individual wearing it. We think of email security in much of the same way. It cannot keep your inboxes completely free of suspicious or malicious content, but it adds significant protection to email communications. From end-user training to impersonation protection, sandboxing and beyond, these solutions are must-haves for every organization. It’s time to buckle-up your inbox.

Pick of the litter

Barracuda Total Email Protection provides every single feature on our wish list and then some. It uniquely supports functionality for the backup and storage of Office 365 files. The variety of its features and 24/7 support make Barracuda’s competitively priced solution an SC Labs Best Buy.   

IronScales IronThrone also checks off almost every feature on our list, but but what makes it stand out is that IronScales has taken innovation to heart with Themis, an AI implementation of a security analyst that triages and acts on reported emails. Its expansive features, including Themis’s next-gen email security approach, makes IronScales our SC Labs Recommended product for this month’s round of reviews.
