Why Many Organizations Are Paying for Security Features They Already Own
Many organizations assume they need a stack of third‑party security tools to protect their environment. But for companies running Microsoft 365, especially Business Premium, E3, or E5, the truth is often the opposite. Microsoft already includes a deep suite of enterprise‑grade security capabilities across Defender, Purview, and Entra. Yet businesses continue to pay for overlapping tools simply because they do not realize what they already own or they have never fully activated the features included in their licensing.
The result is predictable: higher costs, more complexity, and a fragmented security posture that is harder to manage.
A common example is endpoint protection. Even though Microsoft Defender for Endpoint is included in many Microsoft 365 plans and consistently ranks as a top‑tier security platform, organizations often keep legacy antivirus tools out of habit. They end up paying twice for protection, once to Microsoft and once to a third‑party vendor, without gaining any meaningful security advantage.
The same pattern shows up with data loss prevention. Microsoft Purview already provides robust DLP capabilities, including sensitive information detection, labeling, retention, insider risk analytics, and compliance templates for standards like PCI, HIPAA, and ITAR. But because teams are not aware of what Purview can do, they purchase separate DLP tools that do not integrate as cleanly with Microsoft 365 and add unnecessary cost.
Identity is another area where duplication is rampant. Microsoft Entra ID includes MFA, conditional access, single sign‑on, password-less authentication, and even privileged identity management in higher tiers. Despite this, many organizations continue to pay for separate MFA apps, SSO platforms, or identity governance tools. In most cases, Entra already covers these needs natively and more seamlessly.
Email security is no different. Defender for Office 365 provides anti‑phishing, anti‑spoofing, Safe Links, Safe Attachments, and automated remediation. Yet companies still subscribe to third‑party email gateways that replicate the same protections Microsoft already delivers.
Even at the SIEM/SOAR level, organizations on Microsoft 365 E5 or Defender XDR often buy separate platforms without realizing they already have access to Microsoft Sentinel and automated incident response capabilities. These tools integrate deeply with Microsoft 365, Azure, and Windows, often making them more effective than external alternatives.
So why does this happen? In most cases, organizations simply do not know what is included in their Microsoft 365 licensing. The licensing matrix is complex, and IT teams rarely have time to decode it. Many companies also inherit legacy tools from before their M365 migration and never revisit them. And there is a lingering assumption that third‑party tools are “better,” even though Microsoft’s security stack has matured dramatically in recent years.
The good news is that this overspending is fixable and the savings can be significant.
