Our recent kernel and driverdevelopment projects
Developing Drivers for Low Latency Virtual Reality Headsets
Our team designed and delivered two drivers and a data transmission protocol even before the client’s device was ready for release.
The drivers are WHQL certified and help the device operate with 3–10 ms of latency and ~11 Gbps data transmission speed. The client successfully released their product and received positive feedback on it.
Improving a Windows Audio Driver to Obtain a WHQL Release Signature
Apriorit helped a British audio technology company rework the Windows driver for their AI-powered product and successfully pass WHLK/WHQL testing.
IRIS has been satisfied with the quality of services provided by Apriorit experts and continues cooperating with us. Our experts are supporting and maintaining the Windows version of the app, improving its security and performance
Developing a Custom Driver Solution for Blocking USB Devices
We helped a client build a driver for managing USB ports on computers that blocks USB devices according to a set of rules, works with different versions of Windows and macOS, and is compatible with other enterprise software.
The driver created by the Apriorit team increased both the value of the client’s product and the client’s competitive advantage.
USB WiFi Driver Development
Apriorit developed a Windows version of our client’s Linux driver for analyzing traffic and detecting cybersecurity threats in WiFi networks. We researched the existing driver and suggested the fastest way to port it to Linux.
We delivered a ready solution in four months instead of the eight months that it usually takes to develop a new Windows driver from scratch.
Developing Software for a Drone Battery Charging and Data Management Unit
Apriorit experts helped a client deliver a successful MVP that consists of Linux software and firmware, AWS-based infrastructure, and mobile apps for Android and iOS.
This project required a diverse development team with experience in various technologies like reverse engineering to get data about device type and charge state, and virtualization to develop software without a physical charging kit.

FAQ
Does Apriorit provide consultations on kernel and driver development for developers?
<p>Our focus is on providing kernel and driver development and quality assurance services, but we can consult with your team as a separate service.</p>
If you’re looking for free community support, specialized development forums and subreddits are still a good resource for peer advice on specific kernel and driver topics.
How do we get started on a driver development project with Apriorit?
<p>Collaboration typically starts with a short introduction and signing an NDA to ensure confidentiality. Our team then holds an intro call to clarify your expectations and requirements.</p>
<p class=mb-0>If you already have a detailed specification, our engineers will carefully analyze it, provide a development plan, and start the project.</p>
<p>If you don’t have a specification or have one but it’s incomplete, we will conduct a discovery phase to assess your project’s feasibility, define requirements, and prepare a full specification and development plan. This stage may require direct communication with our business analysts or engineers.</p>
For custom devices, we request a hardware sample. For bug fixes, we run diagnostics and provide detailed reports, whether you supply source code or only driver binaries.
When do I need a discovery phase for successful driver development?
<p>A discovery phase is important when there’s no complete or up-to-date driver specification. It helps define the project scope, clarify technical requirements, and identify potential issues before development begins.</p>
If you already have a driver that needs to be fixed or upgraded, a discovery phase helps to locate bugs, reveal compatibility gaps, and address performance problems in existing or off-the-shelf solutions. This ensures accurate estimates, a clear development plan, and smoother execution without unexpected delays.
How can I be sure that Apriorit is the right partner for my driver project?
<p>With over 20 years of experience in low-level development, Apriorit has built and tested drivers for a wide range of operating systems and devices — including custom hardware. Our secure development practices, strong cybersecurity expertise, and proven SSDLC ensure data protection and reliability.</p>
We combine technical depth with rigorous testing, helping clients release stable, compliant, and high-performance drivers efficiently.
What kind of post-development support and maintenance do you offer for driver projects?
<p>Upon delivery, our customers have an acceptance period to verify that the driver meets all requirements. After a customer accepts delivery, we provide a 90-day warranty period, during which we’ll fix any issues free of charge.</p>
For ongoing needs like hot fixes, debugging, or resolving user issues, Apriorit offers optional post-development support as a separate service, available on an hourly (<a href=/rd-services/time-and-materials-model>time and materials</a>) basis or via a <a href=/rd-services/dedicated-teams>dedicated team</a> for large-scale maintenance. This flexibility ensures your driver remains secure, stable, and fully functional long after deployment.
Have you worked with my type of device or protocol?
<p>Most likely, yes. Apriorit has over two decades of experience developing and testing drivers for diverse devices, protocols, and environments.</p>
<p>If you’re working with a custom device or protocol, or your technology isn’t listed in our tech stack, share the details with us. Our experts have extensive experience in kernel and driver development and can quickly get up to speed with your technology. </p>
During an introductory call, we’ll confirm our relevant experience, present similar case studies, and share client testimonials. Our expertise spans both standard and highly specialized custom hardware.
How much will my driver development project cost?
<p>The cost depends on project complexity, available documentation, and whether you’re developing a new driver or updating an existing driver. After reviewing your requirements and any code provided, our engineers will deliver a detailed project plan with a budget, suggested resource allocation, and timeline.</p>
Driver development and QA typically takes 1.5 to 2 months. We usually work on a fixed-price basis, but we can also offer time and materials or dedicated team models for projects that need more flexibility.
