Estimated read time 4 min read

In the realm of protecting business communications, email security is paramount. Organizations often choose between managed email security and traditional email security solutions. This article explores the differences, benefits, and drawbacks of both approaches to help businesses make an informed decision.

Understanding Managed Email Security

Managed email security involves outsourcing email protection to a third-party service provider. This provider handles all aspects of email security, from threat detection and mitigation to compliance and user training. Managed email security services are typically cloud-based, providing real-time protection and updates.

Key Features of Managed Email Security

  • Advanced Threat Detection: Uses machine learning and AI to detect and block sophisticated threats like phishing, malware, and ransomware.
  • Spam Filtering: Effectively filters out spam emails, reducing clutter and potential risks.
  • Email Encryption: Ensures the confidentiality and integrity of email communications.
  • Data Loss Prevention (DLP): Prevents sensitive data from being leaked through emails.
  • Continuous Monitoring: Provides real-time monitoring and incident response.
  • Compliance Support: Helps businesses meet regulatory requirements such as GDPR, HIPAA, and PCI DSS.

Understanding Traditional Email Security

Traditional email security typically involves on-premises solutions that are managed internally by the organization’s IT team. These solutions include software and hardware that need to be installed, configured, and maintained by the business.

Key Features of Traditional Email Security

  • In-House Control: Complete control over email security policies and configurations.
  • Customizable: Highly customizable to fit specific organizational needs and infrastructure.
  • On-Premises Solutions: Security tools and protocols are managed and maintained on-site.
  • One-Time Cost: Generally involves a one-time purchase cost for the software or hardware.

Comparing Managed Email Security and Traditional Email Security

Ease of Management

Managed Email Security: Offloads the management burden to the service provider, freeing up internal IT resources. The provider handles updates, monitoring, and threat mitigation. Traditional Email Security: Requires significant in-house resources for installation, management, updates, and ongoing maintenance.


Managed Email Security: Highly scalable, easily accommodating business growth and fluctuating email traffic without additional infrastructure investments. Traditional Email Security: Scaling up requires purchasing and installing additional hardware and software, which can be time-consuming and costly.

Cost Considerations

Managed Email Security: Typically operates on a subscription-based model, providing predictable monthly or annual costs. It reduces the need for upfront capital investment in hardware and software. Traditional Email Security: Involves significant upfront costs for purchasing and installing hardware and software. Ongoing costs include maintenance, updates, and potential need for additional infrastructure as the business grows.

Security and Compliance

Managed Email Security: Continuously updated to protect against the latest threats. Providers often include compliance features to help meet regulatory requirements. Traditional Email Security: Security depends on the organization’s ability to keep systems updated. Ensuring compliance may require additional effort and resources.

Incident Response and Support

Managed Email Security: Offers 24/7 monitoring and expert support, ensuring rapid response to any security incidents. Service providers typically have dedicated teams for threat analysis and incident management. Traditional Email Security: Incident response depends on the internal IT team’s availability and expertise. Handling security incidents may require additional training and resources.

Flexibility and Customization

Managed Email Security: While highly effective, customization options may be limited compared to in-house solutions. Businesses must rely on the provider’s features and configurations. Traditional Email Security: Offers greater flexibility and customization, allowing businesses to tailor security measures to their specific needs and preferences.

Choosing between managed email security and traditional email security depends on various factors, including the size of the organization, available resources, budget, and specific security needs. Managed email security offers scalability, reduced management burden, and continuous protection, making it ideal for businesses seeking a hands-off, comprehensive solution. Traditional email security, on the other hand, provides greater control and customization, which might be preferred by organizations with specific requirements and the resources to manage security internally. Carefully evaluating these factors will help businesses select the right approach to safeguard their email communications.
