Best Email Security Services

Email is one of the most popular tools used for personal and business communication in the modern era. However, email is insecure by design. When you send an email, that email is plaintext and stored on someone’s computer.

There’s no guarantee that your message is protected in transit or at rest. You are trusting the administrator of that computer not to read through your email. Email security refers to the measures taken to protect the confidentiality, integrity, and availability of electronic mail messages and their transmission. This includes protecting against unauthorized access, use, disclosure, disruption, modification, or destruction of email communications.

Without the right security measures, email can easily serve as a gateway for cyber attacks. A single act of negligence can compromise the safety and security of the organization’s email system. Attackers can spoof domains to make it appear that their emails are from trusted contacts, they can distribute malware and spam via email channels, and they can use social engineering to trick users to make payments or log into websites that contain malicious content. This makes email security one of the most important measures organizations must have.

Email security is important for the following reasons:

  • Confidentiality Email messages may contain sensitive information such as personal information, financial data, and confidential business information that must be protected from unauthorized access and disclosure.
  • Integrity Email messages must be protected from unauthorized modification or alteration to ensure that the information they contain is accurate and reliable.
  • Availability Email is a critical communication tool, and ensuring that email messages are available to authorized users is essential for business operations and personal communications.
  • Compliance Many organizations are subject to regulations that require them to protect sensitive information, including email communications.
  • Reputation A security breach can damage an organization’s reputation and lead to a loss of trust and customers.

Having strong email defenses and protection solutions in place allows organizations to prevent and mitigate the risk of email-related cyberattacks and wade off malware threats before they even reach users’ mailboxes. This article outlines the ten best email security services to help you minimize exposure to email security risk in your organization.

The best email security services

1. Guardz (FREE TRIAL)

Guardz Email Security Software

Guardz is a cloud platform that provides a package of corporate security services.

The package includes an email security scanning service. That email scanner guards against phishing attempts, ransomware, spam, malware, and business email compromise.

Key Features:

  • Comprehensive Email Security: Offers robust protection against phishing, ransomware, spam, malware, and business email compromise.
  • Cloud and Endpoint Protection: Enhances security with cloud data protection and endpoint security against malware and ransomware.
  • Automated Scanning: Automates the security scanning process, requiring no manual intervention for continuous protection.

  • MSP-Friendly: Designed specifically for managed service providers, with brandable consoles for customization.

Why do we recommend it?

Guardz is recommended for its comprehensive suite of security services, particularly its email security capabilities that safeguard against a wide array of threats. Its automation of scans and threat removal, coupled with user education tools, makes it a valuable asset for improving an organization’s security posture. The platform’s MSP-friendly design and ease of integration further enhance its appeal.

This service is available through a plug-in for Microsoft 365 and Google Workspace. When the Guardz system spots a malicious or suspicious email, it automatically removes it from the user’s mailbox and puts it in a secure area for analysis.

The Guardz package isn’t limited to protecting email. It also provides cloud data protection and endpoint protection. Malware and ransomware are important targets for the cloud and endpoint scanning units. The package also provides a phishing simulator and user awareness training units.

Guardz has an unusual marketing strategy. The package is intended for use by managed service providers (MSPs). However, the sales website for the service reaches out to consumer companies – the businesses that will be protected by the platform, rather than those that will operate it. Guardz maintains a list of MSPs with which it partners and recommends that inquiring companies contact one of those providers. Other options are for a company to go and find an MSP and tell them about the Guardz package or tell their existing MSP about the package.

The Guardz console is brandable, so MSPs can put their own logos on the dashboard screens. The package is delivered from the cloud, so an administrator just needs to set up technician accounts to get the MSP onboarded.

Who is it recommended for?

This platform is ideal for managed service providers looking for a comprehensive security solution to offer their clients. It’s also suitable for businesses using Microsoft 365 or Google Workspace and seeking to improve their email and overall cybersecurity through an MSP. Guardz’s approach to security, focusing on both protection mechanisms and user training, makes it a fitting choice for organizations prioritizing a strong defense against digital threats.

The system is available for a 14-day free trial.

2. Fortra Agari Email Security (GET A DEMO)

Fortra Agari Executive Overview

Fortra Agari Email Security is a cloud service that implements DMARC. The system provides a validation of all emails sent on a protected domain. The service influences the email servers of recipients, so it is only effective with participating email systems. However, its aim is to prevent your company’s email addresses from being used for spoofing.

Key Features: 

  • Validates Email Sources: Confirms an email that has originated from the protected domain
  • Enforces Corporate Email Policy: Alerts to inappropriate content
  • Maintains a Spoofer’s Blacklist: Registers the IP address of each discovered scammer
  • Sender Notification: Informs the sender that the email has been blocked

Why do we recommend it?

We recommend Fortra Agari Email Security for its advanced protection against phishing, impersonation, and other email-based threats. Its AI-driven technology provides real-time threat detection and prevention, ensuring that malicious emails are blocked before they reach users. Agari’s integration capabilities enhance email security without disrupting daily operations.

If someone from your company sends an email, that event is logged with the Agari server in the cloud. The email server of the recipient then checks with Agari when it receives an email. If the email was sent from your domain, the email is approved and sent on to the recipient’s inbox. If it isn’t on the Agari register, it is a fake and the email is rejected.

Identifying whether the address shown for the sender is actually spoofed has two benefits. First, it prevents your associates and customers from being scammed by someone pretending to be from your company. Secondly, the system also operates for internal emails. This blocks what is known as a business email compromise. In a BEC attack, a scammer pretends to be a company manager and instructs an administrator to send a payment.

Who is it recommended for?

Fortra Agari Email Security is ideal for organizations of all sizes looking to enhance email security. It is particularly recommended for businesses facing high volumes of phishing attacks, needing compliance with email security regulations, or requiring advanced threat protection to safeguard sensitive data and maintain trust with clients and partners.
