What We Solve
Design and ship kernel-mode components with the same seriousness you would apply to core production infrastructure.
We design kernel components for products that need native performance, stronger local control, and tighter observability. We focus on controlled execution, diagnostics, and outcomes that remain supportable after launch.
That usually shows up as unstable deployments caused by fragile kernel integrations, crashes and blue screens without a dump-first workflow, performance bottlenecks at I/O and scheduling boundaries, and security gaps from weak policy enforcement and unsafe defaults.
What You Get
- Design docs and integration boundaries that survive handoff and support
- Signed, package-ready deliverables with rollout and rollback strategy
- Debug plan for dumps, ETW, postmortems, and triage workflows
- Compatibility strategy across OS versions and update cycles
- Performance baselines with before and after metrics
- Support-ready documentation and knowledge transfer for internal teams
Stack and Use Cases
Windows Kernel
- KMDF, WDM, minifilters, device virtualization
- ETW instrumentation and low-overhead tracing
- Crash dump workflows and triage pipelines
- Signing, packaging, installer design, and upgrade-safe rollout
Linux Kernel
- Kernel modules and platform integrations
- Performance profiling and regression baselines
- Observability and controlled eBPF usage when appropriate
- Compatibility strategies across kernel versions and deployment targets
Typical Use Cases
- Driver development for hardware, protocols, and custom devices
- File system and I/O control: policy enforcement and safe redirection
- Reliability hardening: crash reduction and fault isolation
- Latency work: p99 and p99.9 improvements with clear metrics
- Endpoint and agent software that requires deep OS integration without destabilizing the host
Security Hardening
- Integrity monitoring and attack surface reduction
- Safe defaults and policy enforcement
- Threat modeling when the deployment requires it
- Telemetry for detection, diagnostics, and forensic readiness
Why Teams Choose SToFU Systems
Senior-led delivery. Clear scope. Direct technical communication.
02
Bounded First Step
Most engagements start with a review, audit, prototype, or focused build instead of a giant retained scope.
03
Evidence First
Leave with clearer scope, sharper priorities, and a next move the business can defend under scrutiny.
