Since our inception in 2014, we've worked with over 150 clients. From large multinationals, corporations and SMBs, to civil society, open-source projects, NGOs and (small) human rights organizations.
Our team currently consists of more than 50 staff members. Our area of expertise is very broad: web application, mobile application, code audits, infrastructure, Red Teaming, hardware and embedded, cryptographic audits, protocol audits, social engineering, phishing, physical/mystery guest, security trainings and workshops, and incident response.
Some of the audits require special or niche skills and can be uniquely challenging. We work on high-profile projects regularly. Examples include the European Commission, Covid apps (Dutch Ministery of Health), Dutch energy grid, core internet providers, Google, lots of SMEs, and a wide variety of nonprofits, open source projects, and civil society - F-Droid, Homebrew, Ushahidi, Mullvad VPN, Tauri, and many more.
Being a nonprofit in the cyber security world is extremely rare; giving away 90% of our profits to charity (NLnet Foundation) makes ROS a unique place to work. We offer flexibility in location and working hours, a knowledgeable and highly technical group of colleagues, and market-conform pay.
ROS has staff based all over the world. The core of the team resides in Western Europe, but we also have colleagues in Canada, US, Peru, South Africa, Australia, and India. Given the freedom of working remotely, you will have a lot of flexibility and space to plan your own time.
