Digital Trust for Critical Infra
Open Source Tech Services is a Singapore-based cybersecurity consultancy specializing in systemic risk management, secure architecture, and infrastructure protection for both centralized and decentralized systems.
Our Core Philosophy
We believe that robust security is not a product, but a process achieved through a systemic understanding of risk. Our methodology is rooted in a first-principles approach, focusing on preventing incidents before they occur rather than reacting to them after damage is done.
By analyzing the intersection of technology, operations, and governance, we design resilient systems built to withstand complex and evolving threats. This approach allows us to address novel security challenges and develop innovative solutions where conventional methods fall short.
