I'm Chandra Majumdar, a Partner in Deloitte Canada's Cyber practice. I'm passionate about building resilient cybersecurity infrastructure and driving proactive defense against evolving threats.
I work directly with organizations to understand their unique risks, implement effective detection and response strategies, and prepare for the challenges ahead. I believe a safer, more resilient digital future starts with the willingness to keep learning, experimenting, and challenging assumptions.
ByteSecLabs is my independent space to do exactly that: explore ideas, build tools, and share personal research from my home lab.
