Firmware Readiness Review
A structured read of where your connected product stands against CRA, PSTI, RED and customer-audit expectations — before someone external reads it for you.

Talltree® Technologies
Firmware evidence before somebody asks.
TallTree helps connected-product teams make secure boot, OTA, SBOM, vulnerability handling and support-period decisions inspectable — before a regulator, customer or buyer opens the file.
What teams come to us with
The work between firmware reality and external proof.
The engineering is usually real. The evidence is usually scattered. We close the gap before someone external opens the file.
Our product ships into the EU in 2027 — we don't know what the technical file is supposed to look like.
A customer security team sent us 180 questions about firmware update integrity. We can answer maybe 40 with confidence.
The buyer wants to see the SBOM tied to the released binary, the support-period commitment, and proof of the rollback path. We have most of that, somewhere.
How we engage
Three engagements, one shape of work.
Every engagement produces named risks, owned decisions, and an evidence trail tied to a specific release.
Security Evidence Sprint
Turn scattered engineering knowledge — boot, OTA, SBOM, vulnerability handling, support windows — into a defensible technical file tied to specific releases.
- Technical file gaps
- Update and support evidence
- Residual risk log
Launch Risk Review
Identify the architectural, integration and lifecycle risks in a connected product that are likely to surface late — at certification, in the field, or under acquisition diligence.
- System assumptions
- Version dependencies
- Recovery paths
Flagship writing
From unclear risk to a first conversation.
Five pieces for firmware and engineering leaders preparing connected products for CRA, PSTI, RED, customer audit or acquisition diligence.
Compliance as craft
The point of view behind TallTree: compliance is engineering made inspectable, not paperwork bolted on at the end.
What the CRA actually demands of firmware
Cyber Resilience Act Annex I translated into firmware architecture, release process, field telemetry and evidence for connected-product teams.
Sample CRA gap assessment
A fictional but realistic 13-page report for a connected-lighting manufacturer — the structure, tone and specificity of a serious engagement.
The recovery path we should have tested
An anonymised firmware lesson about OTA rollback, field recovery and why evidence built before panic is different from evidence assembled after it.
Should you handle CRA in-house or bring in a specialist?
Five decision questions for connected-product engineering leaders deciding whether the first CRA cycle should be internal or externally supported.
Frequently asked
Before the first call.
Are you a certification body or a test lab?
No. TallTree is independent advisory. We sit between firmware engineering and the people who will read your evidence — regulators, customers, buyers, insurers — and make sure the work in the file matches the work in the product.
Who is this for?
Connected-product teams shipping firmware on Linux, RTOS or bare-metal targets, preparing for the EU Cyber Resilience Act, UK PSTI, Radio Equipment Directive cybersecurity articles, customer security questionnaires, cyber-insurance reviews or acquisition diligence.
How is an engagement structured?
Most engagements start with a Product Security Readiness Call. From there we usually run a Readiness Review (1–2 weeks), an Evidence Sprint (3–6 weeks tied to a release) or a Launch Risk Review timed against your certification or shipment date.
Do you write the technical file for us?
Where the engineering exists and the gap is articulation, yes. Where the engineering itself is incomplete — for example, no tested rollback path, no signed boot chain, no support-period commitment — we say so. A polished file over weak engineering is not what serious readers want.
The product can work and still not be ready for the file.
If your team is preparing for CRA, PSTI, RED, a customer audit, diligence review or launch deadline, the readiness call is the entry point.
