Firmware Security Analysis
Firmware is the code beneath the software, and it's often the least scrutinised. We analyse device firmware for hardcoded secrets, insecure update mechanisms and exploitable flaws, securing the layer attackers love because no one else looks.

What this means. An authorized Solvex administrator registered and approved this exact public identity. What it does not. Solvex has not inspected the account on the platform, and this is not the platform's own verification.
Solvex specialists never ask for your passwords, recovery phrases, one-time codes, or payments to a personal account. Work, scope and invoices are agreed in writing through the official channels on this site.
Signed authorization required. This engagement is performed only against systems you own or are contractually authorized to have tested, under an agreed scope. See the responsible testing policy.

Evidence and reporting
How the work is kept honest- Evidence, frozen at issuanceFindings tie to something observed. When the report is issued, the evidence behind it is frozen in the same transaction and cannot be edited afterwards.
- A signed reportAn Ed25519 signature covers both the report content and the delivered file. Alter a byte of either and verification fails.
- Signed scope firstTesting starts only after written scope and signed authorization for systems you own or are entitled to have tested.
Anyone holding a Solvex report can verify it publicly without seeing its contents.
Our boundaries
What this engagement does not do, stated before it starts.
- Only firmware you own or are licensed and authorised to analyse
- No circumvention of protections you have no right to bypass
- Findings shared only with the authorised client
- No redistribution of firmware images
How this engagement runs
- 01
Intake
Tell us the system, the goal and the constraints. If the work is not a good fit, we say so before anyone is invoiced.
- 02
Scope and authorization
Written scope and signed authorization before anything is touched. Security testing runs only against systems you own or are contractually entitled to have tested.
- 03
Investigation or build
Specialists matched to the work. Findings are proven by hand — scanner output is a lead, never a finding.
- 04
Evidence
Every finding ties to something observed. When a report is issued, its evidence is frozen in the same transaction, so what backed the report cannot change afterwards.
- 05
Delivery
A signed report: an Ed25519 signature over both the content and the file, with a short verification reference you can read down a phone.
- 06
Verification and retest
Anyone holding the report can verify it publicly without seeing its contents. Fixes are retested as part of the engagement — “fixed” means we confirmed it.
Questions we are asked
- What do you find in firmware analysis?
- Commonly: hardcoded passwords and keys, unsigned or insecure update mechanisms, exploitable vulnerabilities, and occasionally hidden backdoors. These are exactly the flaws attackers hunt for.
- Do you need the physical device?
- Not always — we can often work from a firmware image. Physical access helps for extraction and dynamic testing, which we combine with hardware testing where useful.
- What do you need from us?
- The firmware image or device, any documentation, and written confirmation you own or are authorised to analyse it. We won't bypass protections you have no right to circumvent.

Hardware Security Testing
Physical devices carry physical risks. We test your hardware — embedded devices, point-of-sale, access-control, custom electronics — for tampering, debug exposure and extractable secrets, so a device in the wild can't betray your systems.

IoT Security Testing
Connected devices multiply your attack surface fast. We test IoT devices and their ecosystems — hardware, firmware, apps and cloud — for the weaknesses that let attackers hijack devices or use them as a way into your network.
