How MSPs Can Have Greater Control Over Secure Email Gateways

By Kevin Beatty


Data breaches set new record highs in 2021 as more than 5.9 billion accounts were compromised. Not only did the number of breaches increase, but the number of records exposed for each breach increased by more than 70%. 




Three factors are contributing to the increase in threats: 

  1. Cybercriminals and threat actors are becoming increasingly more sophisticated in their attacks. 
  2. The significant  increase in remote and hybrid workers. 
  3. Easy to use hacking tools and hackers for hire, such as  Ransomware as a Service (RaaS) that can be launched without technical expertise. 

Increasingly, cybercriminals are attacking managed service providers (MSPs) or leveraging customer accounts to access MSP databases and spread malware to other clients. For MSPs, it can easily become a nightmare scenario. 

A  2022 survey of MSPs made it clear just how big the threats are. 82% of MSPs reported increased attacks over the past year, and 90% said they had experienced a successful cyberattack. More than half of those surveyed said they had experienced business disruption and financial losses, including: 

  • Lost business 
  • Damage to reputation 
  • Loss of trust from customers 

Besides the increased threat, researchers concluded that many MSPs are still not implementing the necessary security control to protect their customers and their business. 


Protect Your Network and Your Customers 

Email security is not just about protecting individual client assets either; it’s about protecting your own network and all of your clients. The  Kaseya VSA supply chain attack in 2021 targeted MSPs directly and caused significant damage. Once inside the MSP infrastructure, ransomware spread to customers, hitting thousands of endpoints. For customers, the MSP they were paying to manage and protect their network suddenly became their attacker.

With Kaseya, attackers exploited an authentication vulnerability in the company’s web interface, allowing them to circumvent controls, upload a malicious payload, and execute commands using SQL injection. This pushed malicious software in the form of ransomware disguised as a necessary software update to end-users.  

If a malicious email can get past your defenses, you open yourself up to threats similar to how the attack on Kaseya worked. When threat actors get access to your network, they can then attack your customers downstream. 

A secure email gateway is not just important, it’s essential to protect your network and your customers. 


What Is a Secure Email Gateway? 

A secure email gateway (SEG) is an email security solution that works between company email servers and the public internet. It acts as a virtual firewall for email traffic and inspects both incoming and outgoing emails for malicious content including attachments and URLs. SEGs also offer protection from social engineering attacks, including phishing or  business email compromise. SEGs work by identifying potentially malicious emails and placing them in quarantine or blocking transmission. 

As email continues to be the number one target for threat actors, a secure email gateway provides the first line of defense. 


Protecting from External Email Threats 

The best secure email gateway solutions will perform multiple security tests on inbound emails to block outside threats from being delivered. By running multiple filters and security tests on inbound email, it reduces the chance that any single point of entry can be exploited. 

MDaemon Technologies SecurityGateway™ protects incoming email by employing: 

  • Anti-spam 
  • Anti-virus 
  • Anti-spoofing 
  • Anti-abuse 
  • Email authentication 
  • Email filtering 
  • Accept lists / reject lists 


Protecting from Internal Email Threats 

Threats can also come from inside an organization. It’s important for companies to prevent data leaks and safeguard their sensitive company data. 

MDaemon Technologies SecurityGateway  protects outgoing email by employing: 

  • Data leak prevention 
  • SSL and TLS encryption 
  • Automatic redirection of HTTP requests to HTTPS 
  • Policy enforcement 
  • Content filtering 


Many Third-Party Solutions Aren’t Mitigating Threats 

Many MSPs rely on a third-party solution for their email security, which can severely limit their control over secure email gateway settings. In many cases, this means more administrative tasks for managing users and no access to logs, making troubleshooting difficult. As such, it requires more maintenance and leads to longer customer resolution times. Unfortunately, this additional burden is not something that can be billed to customers, so it also adds to expenses. 



As the threat landscape continues to evolve, MSPs need greater control over their email security for customers. A secure email gateway provides simple, powerful, and robust protection against spam, phishing attacks, malware, account takeover attempts, and more.

  • Inbound & outbound message logs 
  • Advanced message log filtering 
  • Global and domain logs
