Yocto, Buildroot, or OpenWrt: the bring-up is done, that was the easy part.
Kernel CVEs keep landing, layers drift, the toolchain breaks somehow, and regulators now want a vulnerability story. We keep your image patched, buildable, and compliant, so you don't keep a Linux platform engineer on payroll.
Most teams can do the bring-up. Almost none can keep it current.
"The build only works on one person's machine, and that person is gone."
We onboard the build, get it reproducible inside a versioned, snapshotted machine on our infrastructure, and document the process. From then on, every build is repeatable and auditable.
"We have no idea which vulnerabilities affect our shipped image."
We establish a CVE baseline against the running image, then track and patch on a fixed cadence. Each cycle produces an updated SBOM and a vulnerability report you can hand to auditors or customers.
"Pulling one upstream fix now means untangling a year of divergence."
We keep the layer state current and the toolchain alive, so when you do need a fix or a feature, the path to it is short instead of a multi-week archaeology dig.
The EU Cyber Resilience Act applies to products already on the market, not just new ones
Under the EU Cyber Resilience Act, vulnerability and incident reporting obligations begin 11 September 2026, with full compliance required by 11 December 2027. A fielded product with no maintenance story is now a liability, not just technical debt. We deliver the documented, ongoing vulnerability handling the regulation expects: a current SBOM, a tracked CVE status, and a record of what was patched and when.
Selling only in the US? There is no American CRA, and that changes less than you would hope. A device you cannot patch is a liability the day it ships, mandate or not.
The United States has no Cyber Resilience Act. You are still on the hook for the device you put in the field.
A CVE lands against your shipped image. Days later, fielded units are conscripted into a botnet, the way Mirai was built. Your product is now attacking someone else's network, your name is on it, and nobody can rebuild the image to ship a fix. The regulation was never the threat. This is.
An emergency field response costs far more than keeping the image current. The maintenance is the cheap side of a risk you already own.
Onboard the build once, then keep it healthy on a predictable cadence
We take a look at the build and evaluate the reproducibility before any maintenance contract begins. Maintaining a build we have never reproduced is how you waste money, so this is required and genuinely valuable on its own.
On a fixed cadence, per maintained image, we keep the image current and documented.
Some vulnerabilities cannot wait. Each retainer includes a defined allowance of out-of-band hours for actively-exploited CVEs.
When maintenance turns into real engineering work, BSP clients get priority scheduling instead of waiting in line.
Yocto, Buildroot, and OpenWrt, on the hardware you already shipped
A single file PDF self-audit. Find out where your shipped image stands before the September 2026 deadline.
Start with a few questions that tell you whether your fielded Yocto, Buildroot, or OpenWrt product has a maintenance story, or a liability:
The full PDF expands these into a complete self-audit: every checkpoint across reproducibility, CVE tracking, SBOM, documentation, and CRA obligations, scored so you can see where you stand, with a short note on what each gap actually means and how to close it. Enter your email and we'll send it over. Any item you can't check off with a confident "yes" is exactly what a maintenance retainer fixes.
Tell us about your image and we'll let you know if we're a fit, usually within one business day.
Build won't even reproduce, or the firmware itself is the problem? Start with an MCU and firmware rescue first, then keep it healthy here.
