A driver development company develops software at the kernel level so that hardware can interact with operating systems. This excludes standard embedded systems companies developing firmware without kernel access, and it excludes application-level development companies without kernel-level integration.

The best driver development companies have experience with the Windows Driver Model (WDM), custom Linux kernels, embedded development, security protocols, and memory management. Many driver development articles actually profile embedded systems companies, and not kernel development companies.

In our analysis, we only evaluated five driver development companies that could provide secure, production-level driver and kernel development services. Our evaluation criteria were based on depth in kernel-level systems, security, certifications, expertise in Windows drivers, embedded, lifecycle capabilities, and experience. We also looked at experience as measured by employee headcount and time in business.

These criteria and differences matter. A company may be good at developing embedded systems software, but it may not be able to provide the security necessary to develop secure embedded driver systems. Also, a company may specialize in kernel systems, but may not have the resources necessary to handle embedded systems development for automotive companies. These differences are worth noting and evaluating for each company.

How to choose the right driver development companies

Developing drivers is different from general embedded software engineering and requires very strict attention to detail and security. Seek out a service provider that demonstrates a deep understanding of kernel-level development and a security-oriented approach. Here’s how to vet them:

• Driver expertise: Make sure they have a portfolio of projects that includes Windows driver development for production, or embedded driver development for Linux, not general embedded firmware;
• Compliance: Check to see if they’ve obtained ISO 27001, SOC 2, or another compliance specific to a particular vertical (i.e., ISO 26262 for automotive). These certifications will demonstrate that a developer uses security best practices;
• Drivers and embedded experience: Make sure that the developer has experience developing Windows and embedded drivers by asking for references and case studies.
• Full lifecycle: If there is only partial knowledge of driver development, there will always be questions, and this will mean there must be hand-off between vendors. Seek out a vendor that is a one-stop shop and understands the entirety of the design, development, testing, and production process;
• Staff depth: A good developer should be able to provide an exact headcount of engineers in kernel development roles and a track record that includes multiple years of business. New start-ups that are only two years old do not have that experience;
• IPR terms: Make sure that the developer provides the IPR and full access to source code so that you don’t get locked in.

Top 5 Driver Development Companies

Our selection criteria focused specifically on kernel developers, not generic embedded software engineers. We prioritized those with proven expertise in security best practices and a history of delivering robust, production-ready software.

These five vendors offer rare expertise in kernel and embedded Windows driver development, full software development lifecycle capabilities, and a portfolio of successful case studies.

Their transparent development model uses industry-standard interfaces and open-source libraries. This ensures that the code is portable and reusable. Conclusive Engineering is transparent with its customers, which is not the typical case in embedded system development services. They build custom drivers in line with other services offered by them like FPGA design, custom PCB manufacturing, firmware & embedded software development, and IoT.

It was reported that one of the client, a VP of R&D, commented on Conclusive Engineering that “even though they didn’t have expertise in our industry they still suggested us some improvements in the end that resulted in a better product than what we had initially requested” which is the hallmark of engineering experts who know more than the specific industry but the low-level architecture of devices and components in general.

This week Conclusive Engineering shipped projects. Conclusive Engineering provides integration services for the following:

• Nordic;
• Microchip;
• NXP;
• Texas Instruments;

Trusted by companies like Arduino, Qualcomm, Kingspan, and Enverus, they cater to clients that require dedicated development teams acting as a seamless extension of in-house engineering.

Their software development, particularly for driver development purposes, is not specialized enough and is not built on the kernel level or secured as rigorously as it should be, given this is core work for both the kernel & embedded teams. Testing & QA, Infrastructure & DevOps services are available, yet there is no record of driver or kernel projects on their portfolio to indicate a track record in such production-grade low-level system software development. Their area of expertise leans towards application-based software development and team augmentation rather than the secure, compliance-driven driver engineering the top four provide. They do keep up with industry developments and have been actively shipping content, but their lack of focus on the automotive, industrial and embedded systems verticals puts them outside of their niche requirements.

How to shortcut this list

Different driver development requirements based on security requirements and depth, vertical industry, and outsourcing model: Kernel-level security experts, full-stack embedded product engineering firms, and cost outsourcing companies:

• Kernel-level security experts: Apriorit, Conclusive Engineering;
• Full-stack embedded product engineering firms: Softeq Development Corporation, Embien Technologies;
• Cost outsourcing companies: A-listware.

Conclusion

Nearly every driver development company claims to specialize in embedded systems, yet most are far from kernel specialists; they simply aren’t security conscious or production ready. The five companies listed below offer varying combinations of kernel depth, security, and production maturity.

Whether you prioritize automotive requirements, transferability of IP, or a proven track record in kernel R&D, you should first identify exactly what is required: Windows or Linux? Certified secure? Onsite or offsite? After that, get architecture review documentation from two vendors and compare them. Remember that a good vendor does not mean the largest vendor but rather one whose kernel knowledge and vendor model best matches your needs and risk appetite.
