SELinux and AppArmor enforcement reached 55.6% across enterprise Linux environments in 2025, meaning more than half of all production Linux installations now actively block unauthorized access through Mandatory Access Control. With RHEL holding 43.1% of the enterprise Linux server market and Ubuntu at 33.9%, these two frameworks cover roughly 77% of enterprise Linux just through distribution defaults. The 2025 switch by openSUSE from AppArmor to SELinux as its default MAC framework signals a broader shift toward SELinux dominance in new deployments.
SELinux and AppArmor Adoption Key Statistics
- 55.6% of enterprise Linux environments enforce SELinux or AppArmor as of 2025.
- RHEL, with 43.1% enterprise server share, ships SELinux in enforcing mode by default.
- 86% of Ubuntu servers have AppArmor enabled, and Ubuntu runs on 60%+ of public cloud Linux instances.
- 96.4% of production Kubernetes clusters run on Linux, with both MAC frameworks used to confine containers.
- Organizations using SELinux reported a 60% reduction in privilege escalation incidents compared to permissive-mode deployments.
SELinux and AppArmor Combined Enforcement Rate
A Market Growth Reports study confirmed that more than 55% of organizations deployed SELinux, AppArmor, or a similar security module within the preceding 12 months. This aligns with the 55.6% figure from aggregated industry data, placing the reliable benchmark for MAC enforcement squarely in the 55–56% range.
The 1.3% Linux malware figure is worth reading alongside this data. Enterprises that enforce SELinux or AppArmor tend to layer 2FA (72.1%) and active firewalls (88.4%) on top, building a defense stack that explains Linux’s low malware incidence.
Which Linux Distributions Default to SELinux
SELinux adoption follows distribution defaults. RHEL, Fedora, and CentOS Stream all ship with SELinux in enforcing mode. Since RHEL alone holds 43.1% of the enterprise Linux server market, SELinux is present across…
