80% of Microsoft Exchange Online Migrations Haven’t Fully Leveraged Advanced Security Features


Despite the powerful security features that are part of Microsoft Exchange Online, including multiple layers of security controls, threat intelligence and proactive monitoring, around 80% of the Microsoft Exchange Online migrations we see haven’t fully leveraged advanced security features.

In today’s digital landscape, securing sensitive data and maintaining a robust security posture is incredibly important but many organizations aren’t leveraging the advanced security features of Microsoft Exchange Online and they’re leaving themselves susceptible to security breaches. These capabilities include:

  1. Advanced Threat Protection (ATP)
  2. Data Loss Prevention (DLP)
  3. Multi-Factor Authentication (MFA)
  4. Azure Active Directory Identity Protection
  5. Information Rights Management (IRM)
  6. Threat Intelligence

In this article, we’ll delve into each of these security features, highlighting their benefits and explaining how implementation can significantly enhance the security posture of your organization. But first, let’s take a look at why many organizations fail to fully leverage these capabilities. If you recognize your organization here, Threadfin can help.

Why don’t organizations leverage the advanced security features of Microsoft Exchange Online?

Overwhelming workload

Migration is a complex endeavor that requires significant planning, coordination and resources. Once migration is complete and users are successfully onboarded, organizations are often faced with a backlog of pending tasks and projects. In the midst of catching up and managing day-to-day operations, dedicating time and effort to fully explore and configure advanced security features can fall by the wayside.

Lack of awareness

Organizations may not be fully aware of the robust security capabilities that Microsoft Exchange Online offers or the potential risks they face without them. Teams may have limited knowledge of the features, their benefits and how to configure them effectively. Without a clear understanding of the value these features bring to the organization’s security posture, they are often overlooked or deemed unnecessary.

Limited resources and expertise

Smaller organizations, or those with limited IT staff, may struggle to allocate dedicated resources or acquire the necessary expertise to implement and manage the advanced security features of Microsoft Exchange Online. Configuring policies, defining rules and fine-tuning settings can be daunting without the right skill set or external support. In such cases, organizations may opt for a more simplified approach, relying on basic security measures while overlooking the potential benefits of the advanced features.

Compliance concerns

Certain organizations, particularly those operating in regulated industries, may be hesitant to implement advanced security features due to concerns about compliance requirements and potential disruptions to business processes. The fear of inadvertently blocking legitimate emails or impacting productivity can lead organizations to adopt a conservative approach when configuring security policies.

Perception of sufficient security

Some organizations believe that the default security settings in Microsoft Exchange Online are adequate for their needs. They may not realize additional layers of protection can be enabled through the advanced security features.

What advanced Microsoft Exchange Online security features should organizations leverage?

Now let’s take a look at each of Microsoft Exchange Online’s security features.

Advanced Threat Protection (ATP)

ATP is an additional layer of defense against sophisticated email threats like malware, phishing attempts and zero-day exploits. ATP uses sophisticated machine learning algorithms and real-time analysis to detect and prevent these threats from reaching users’ inboxes. ATP not only helps protect against known threats but also identifies and mitigates emerging threats, ensuring proactive defense against the ever-evolving threat landscape.

Data Loss Prevention (DLP)

DLP capabilities allow organizations to define policies and rules to detect and protect sensitive data, ensuring it does not leave the organization’s boundaries. DLP helps organizations protect information and assists in complying with data protection regulations. DLP policies can be configured to detect and prevent the unauthorized disclosure of sensitive data, such as personally identifiable information (PII), financial records or intellectual property.

Multi-Factor Authentication (MFA)

Passwords alone are no longer sufficient to protect user accounts from unauthorized access. MFA adds an extra layer of security by requiring users to provide multiple forms of identification to access their accounts. This typically involves something the user knows (password), something they have (smartphone or hardware token) or something they are (biometric data). Enabling MFA helps protect against unauthorized access, especially in scenarios where user credentials may be compromised.

Azure Active Directory Identity Protection

Azure AD Identity Protection helps organizations secure user identities and prevent account compromises. It leverages machine learning algorithms to detect and mitigate potential identity-based risks and suspicious activities, such as sign-in attempts from unfamiliar locations or multiple failed login attempts. This proactive approach allows organizations to take appropriate actions to mitigate potential security risks promptly.

Information Rights Management (IRM)

IRM allows organizations to apply persistent data protection to emails and attachments by enabling organizations to enforce restrictions on content, such as preventing unauthorized forwarding, printing or copying of sensitive information. This allows organizations to maintain control over their sensitive data, even when it is shared with external parties.

Threat Intelligence

Microsoft Exchange Online integrates with threat intelligence services that provide real-time threat insights and help organizations stay informed about the latest security risks including emerging threats and known malicious entities. This knowledge empowers organizations to make informed security decisions and strengthen their defenses against evolving cyber threats.


The advanced security features offered by Microsoft Exchange Online are crucial for organizations aiming to protect their sensitive data and maintain a robust security posture that guards against sophisticated cyber threats.
