Summary
👤
Senior🎓
Top SchoolScott Walsh is a Principal Security Researcher with 13 years of experience blending hands-on exploit development, vulnerability research, and large-scale Linux systems administration. He has led threat intelligence and vulnerability engineering efforts at Coalition and SecurityScorecard and built QA-focused emulation and testing infrastructure at Tenable to validate complex protocol behaviors. Comfortable from packet dissection to automation, he routinely codes in Bash, Python, Perl and PHP and leverages Debian, Ansible, BIND and iptables to harden and emulate environments. Scott has run his own security consultancy, researched AV bypass techniques, and designed fraud countermeasures under aggressive deployment schedules. Based in Bedford, Nova Scotia, he combines practitioner-level system tuning and architecture skills with a researcher’s curiosity for attack vectors and defensive innovation. A less obvious strength is his track record of building custom scanning and emulation tooling to test hundreds of thousands of endpoints and maintain plugin quality.
