Privileged Access Management
Heimdal vs Microsoft 365 E3
Microsoft 365 E3 is built for productivity, not cybersecurity. Heimdal adds complete, integrated protection to your existing Microsoft 365 setup by covering all the security gaps left by E3 under one simple license.
Microsoft E3 stays…
Heimdal completes your protection
E3 provides a useful security foundation, but Microsoft’s model relies heavily on extra bolt-ons and costly upgrades. That quickly becomes expensive, complex, and hard to manage.
E3 is only the start
Microsoft E3 has major functionality gaps in privileged access management (requires E5), DNS protection (requires Entra Internet Access), and advanced threat hunting (requires Sentinel). Each additional capability means buying yet another license.
Mixed quality of support
Most Microsoft-managed security support comes through the Microsoft Partner Network, meaning service quality, expertise, and responsiveness vary greatly between providers.
Unpredictable, rising costs
Microsoft security add-ons are expensive, and pricing is often consumption-based. This makes costs difficult to predict or control as your organization grows.
Complexity by design
Microsoft security products have a steep learning curve. Adding multiple bolt-ons makes your security infrastructure increasingly complex and hard to maintain.
Three reasons to choose…
Heimdal over Microsoft
