From silicon to servers. Deep technical expertise in open source, embedded systems, and cybersecurity.
Building or maintaining an embedded product? Are you facing security challenges, architectural decisions, vulnerability reports, or new regulatory requirements?
Ygreky provides independent consulting across the entire embedded system stack, from hardware and firmware to operating systems, networking, and remote infrastructure.
With over 20 years of experience in open source and deep expertise in embedded systems, we help engineering teams solve complex technical problems, improve security, and build products they can maintain over time.
Our expertise
Open Source & Embedded Linux
Linux kernel, Yocto Project, Board Support Packages (BSPs), drivers, Real-Time Operating Systems (RTOSes), and open-source integration. We help you select, adapt, maintain, and contribute to open-source while avoiding unnecessary vendor dependencies and costly forks.
Embedded Security & Hardening
Secure boot, cryptography, operating system hardening, and software supply chain security. We address the complete product, including remote services, update infrastructure, and communication interfaces.
Vulnerability Management & Security Team as a Service
Don’t have a dedicated product security team? We can help you establish vulnerability management processes or handle them on your behalf.
We work from receiving and assessing vulnerability reports to coordinating fixes, communicating with researchers, and publishing security advisories. As a CVE Numbering Authority (CNA), Ygreky can also assign and publish and manage CVE records for vulnerabilities we handle (and within our scope).
System Architecture
From silicon to software and network infrastructure. We do architecture reviews, define security boundaries, advice on system integration, and long-term maintainability. We help you make informed technical decisions based on practical engineering experience.
Cyber Resilience Act (CRA) Readiness
Assess your existing practices, identify gaps, and prepare for CRA requirements. We can help you prepare your product risk assessments, review SBOMs and due diligence data, create or review your vulnerability handling processes and technical documentation.
How we work
Short-term consulting
When you need.. an independent technical review, a specific problem to solve, or expert advice on an architectural decision. Focused engagements lasts from a few hours to several days.
Longer-term engagements
When you need… ongoing technical expertise for product development, open-source integration, security improvements, vulnerability management, and CRA preparations. We work alongside your engineering teams over weeks or months.
Security Team as a Service
When you need… to outsource specific product security responsibilities to Ygreky. We can provide receive vulnerability reports, triage them, handle coordinated disclosure, prepare security advisories, and perform CVE management without requiring you to build a dedicated internal team.
