Firecracker vs Wazuh: at a glance
What is Firecracker?
Firecracker can now run microVMs on Nitro instead of KVM, with the same API.
Firecracker is the open-source microVM monitor behind AWS Lambda and Fargate. 2026 brought PCI virtio hotplug in developer preview (1.16), virtio device reset and richer metrics (1.17), and now 1.18.0 adds Nitro Sandboxes: Firecracker can drive the Nitro Enclaves driver instead of /dev/kvm to launch VMs the Nitro Hypervisor carves out of the parent EC2 instance. The existing API, jailer and virtio device model stay the same, and a new PUT /enclave endpoint selects confidential or direct mode.
What is Wazuh?
Wazuh hardens its 4.14 line while 5.0 rebuilds how agents talk to the manager.
Wazuh ships 4.14 patch releases roughly every two to three weeks, and almost all of the content is security hardening: path traversal and command injection fixes, input validation in the cluster code, connection deadlines and memory leak fixes. 4.14.10 also added memory limits for oversized rulesets and queue warnings for the vulnerability scanner. In parallel, 5.0.0 reached its second release candidate on October 30.

Firecracker can now run microVMs on Nitro instead of KVM, with the same API.
◆ Current state
Firecracker is the open-source microVM monitor behind AWS Lambda and Fargate. 2026 brought PCI virtio hotplug in developer preview (1.16), virtio device reset and richer metrics (1.17), and now 1.18.0 adds Nitro Sandboxes: Firecracker can drive the Nitro Enclaves driver instead of /dev/kvm to launch VMs the Nitro Hypervisor carves out of the parent EC2 instance. The existing API, jailer and virtio device model stay the same, and a new PUT /enclave endpoint selects confidential or direct mode.
◆ Where it's heading
The project is widening what a Firecracker microVM can be without changing how operators drive it: hotplug and reset made the VM lifecycle more flexible, and Nitro support makes the hypervisor backend swappable. Patch releases keep landing on several stable lines at once, so the maintainers are supporting older minors while the feature surface grows.
◆ Prediction
Expect 1.18.x patches that fix Nitro Sandbox edge cases and documentation on which devices and snapshot features work in confidential mode; the release does not say whether Nitro support will leave preview or reach feature parity with KVM.
Wazuh
5.0INFRA · APIS
Wazuh hardens its 4.14 line while 5.0 rebuilds how agents talk to the manager.
◆ Current state
Wazuh ships 4.14 patch releases roughly every two to three weeks, and almost all of the content is security hardening: path traversal and command injection fixes, input validation in the cluster code, connection deadlines and memory leak fixes. 4.14.10 also added memory limits for oversized rulesets and queue warnings for the vulnerability scanner. In parallel, 5.0.0 reached its second release candidate on October 30.
◆ Where it's heading
5.0 is the real change: agents move to HTTPS for talking to the manager, a new detection engine replaces the 4.x analysis daemon, and every server install becomes a cluster node. The 4.14 branch, meanwhile, reads like a security audit being worked through release by release, which keeps current installs safe while 5.0 settles.
◆ Prediction
More 5.0 release candidates are likely before a final release, and 4.14 patch releases with security fixes should keep coming every few weeks; a 5.0 GA date is not stated in these entries.
