Email is a common channel for cybercriminals to hack into a system because it was originally designed to be open and accessible to everyone. Of course, those were the nascent stages of the Internet when such sophisticated attacks were unheard of.

But as the Internet grew, it became a popular vector for attacks as hackers began to leverage its open format. In general, emails can be viewed by anyone who intercepts them during the transfer, or at rest. So, hackers started using a variety of techniques to capture emails and access their content.

To add to it, email has become a critical communication tool in today’s business world, so there is all the more reason to secure it.

Though these steps made email more secure than before, policies alone were not enough, as is evident from the many hacks that have happened over the years.

Along with email best practices, it became necessary to have email security software in place to make emails secure. In this article, we will look at some of the best email security software.

The Best Email Security Software

1. Guardz – FREE TRIAL

Tested on: Cloud

Guardz protects endpoints and cloud data with an email scanning service that forms a major part of its defense strategy. The service is designed to protect the email and cloud services in Microsoft 365 and Google Workspace. So it covers Outlook/Exchange Server and OneDrive and Gmail and Google Drive. 

Key Features

Let’s take a look at the most important services that are included in the Guardz bundle.

• Cloud-hosted system One of the biggest features of the Guardz service is that it monitors the cloud-based Microsoft 365 and Google Workspace packages, so there is no advantage to hosting the software on your own servers.
• Web-based dashboard Access to the console for Guardz can be made through any standard Web browser, so technicians and users don’t need to install special interface software.
• Automated protection from malicious emails This package scans all incoming emails and removes phishing and business email compromise attempts, spam, and reports on the event.
• Malicious email quarantining Detected malicious emails aren’t deleted. Instead, they are placed in a quarantine area where they can be analyzed for threat intelligence purposes and also assessed because they might not actually be malicious. So, the removal can be reversed. 
• Dark Web scanning This feature looks for the identities of a subscribing business on the Dark Web. It will raise an alert if lists of company email addresses are being sold or just disclosed on hacker sites.
• Employee awareness training A library of training videos is included for free in the Guardz package. This can be allocated to individuals or groups of employees and the dashboard records attendance so the system administrator knows when all employees have finished the course.

Why do we recommend it?

The Guardz package is particularly focused on scanning emails as a defense mechanism because emails offer the easiest route for hackers and malware to get into your system. The scanner covers every threat and inconvenience that bad actors can throw at your company. This is an automated system that requires very little setup.

This service is highly automated and it will operate without any manual intervention, so it is ideal for businesses that just don’t have time to deal with email threats but just want to get a service to do that. However, the platform also provides records of attacks and actions to block them, so it also gives administrators that ant to derive insights the tools to analyze their defenses.

Who is it recommended for?

Although Guardz makes a pitch to end-user companies, it only operates through managed service providers. You are not supposed to subscribe to this service and run it yourself. Guardz recommends that you find an MSP and ask them to get you this security system and the company also lists managed service providers that it recommends. One of the plans from Guardz is a managed security service, so in that case, you won’t need to get an MSP as well.

Guadz is available in three editions that have a per-user subscription rate. These are Starter for 1 – 99 users at $9 per user per month, Pro for 100 + users at $5 per user per month, and Ultimate, which is a managed security service and doesn’t have a published price. Get a 14-day free trial.

2. Fortra Agari Email Security – ACCESS DEMO

Fortra Agari Email Security is a DMARC service. That stands for “domain-based message authentication, reporting, and conformance.” It records the from and to information of every email that your users send out. Receiving email servers check with the list and any email that isn’t there must have come from a scammer. 

Key Features

Let’s examine the important services of the Fortra Agari Email Security service: 

• Records valid emails: Registers emails leaving your email system, which enables the receiving email service to check whether each email actually did come from your company and not a scammer.
• Reputation protection: If scammers lock onto your email domain as cover for their cons, your company’s reputation will suffer even though it is completely innocent.
• Protection against business email compromise: A major channel of threats to companies around the world involves a scammer pretending to be a manager within a company and sending an email to an administrator instructing a payment. The Agari system registers valid internal emails as well as those sent to outside recipients, so your email system will automatically block impersonator emails by referencing the validation service.
• Attack analysis: Agari records every failed authentication transaction, which builds up a picture of hacker campaigns using a particular domain for cover. This information is made available to the subscribing company, so their administrators can analyze attacks and perhaps warn associates. 

Why do we recommend it?

Fortra Agari Email Security provides an implementation of DMARC, which is a global protocol that has been set up to defeat email scammers. This system not only warns recipients that an email is fake but it also registers the IP addresses of fake email origins on global blacklists.
