Cossack Labs
Who we are
Cossack Labs is a UK-headquartered cybersecurity company, with R&D offices across Ukraine.
What we do
We design, build, and secure critical systems that must remain operational in high-risk environments across the sectors where failure isn't an option: defence, critical national infrastructure, finance, healthcare, and public sector.
We work across complex security challenges in IIoT and AI/ML systems, robotics, navigation, power grids, payment processing systems, financial and legal platforms, and applications used by millions.
This includes finding answers to unstructured problems in the field of data, device, application, and system security; building novel security controls and protocols; designing entirely new architectures and systems; reverse engineering; and turning theoretical methods into prototypes.
Here are some case studies of our regular work, written from an engineer’s point of view: www.cossacklabs.com/case-studies
We cut through complexity and bring together the best of applied cryptography and pragmatic security to help customers solve real-world problems.
Team
We are a human-centered team of experienced security auditors, academic cryptographers, certified software and security engineers, contributors to global security standards, regulations and frameworks.
Some have worked in infosec since the 1990s, helping shape the industry and write the standards it relies on today.
For newcomers, we offer detailed onboarding during the first weeks. You’ll discover what works for you and what you need to learn next, developing through hands-on work on challenging problems, mentoring, and continuous learning with personal development plans to guide your growth.
Environment
We hire smart people who enjoy challenging work and trust them to do the right thing. As an engineer, you’ll be involved in decision-making at both tactical and strategic levels.
Working at Cossack Labs, you’ll be at the cutting edge of technology and real-world security projects alongside highly skilled professionals who genuinely care about building a safer and more secure future.
We work on cryptographic R&D, share engineering experience in blog posts and at conferences, and volunteer to help Ukrainian companies improve their security resilience during warfare.
