Sunil Attri trained as a mechanical engineer and spent years working in industrial quality assurance before moving into information security, where he focuses on governance, risk management, and organizational accountability. He regularly audits complex management systems, trains professionals, and speaks on privacy and security operations.

His fiction is grounded in real-world engineering, quality forensics, and technical systems failures. He writes quiet, forensic procedurals exploring how reasonable people, acting in good faith and following reasonable procedures, can still arrive at outcomes nobody intended. Set in his home state of Punjab, Who Closed the Alarm? is his latest industrial novel.
