Our People
Our people are at the core of everything we do.
Dev/Null Security is built by Security Specialists who have spent their careers designing, running, and defending security and observability platforms in complex, high-pressure environments.
We believe great security outcomes come from strong relationships, clear thinking, and teams who take ownership. That mindset runs through everyone at Dev/Null, whether they are visible here or working quietly behind the scenes.
Andy Younie
Managing Consultant
With over two decades of experience and a CISSP certification, Andy has built a reputation in finance, retail, and publicsector environments for delivering sophisticated PKI and Vulnerability Management solutions. He has designed and maintained extensive SSL estates and engineered robust PKI infrastructures for financial, and retail organisations, and lead a multiyear SOC transformation for a large publicsector customer. His expertise extends to riskbased exposure management, designing, deploying, and operating RBVM solutions and automating reporting and remediation workflows. A clear communicator and go-to guide, he routinely engages Csuite stakeholders, translates complex security concepts into actionable plans, and mentors junior team members to uphold industry best practices.
Before finding his calling in security, Andy trained as an architect and has had some unusual hobbies as a ghost tour guide, magic consultant, and paraglider pilot.
Tom Wise
Practice Lead, Observability & Analytics
With more than 18 years of hands-on experience in security engineering and IT operations, Tom has built a reputation for delivering high-impact SIEM, SOAR, and automation-led solutions across MSSP and enterprise environments. Known for blending deep technical depth with clear, outcome-driven communication, he works closely with senior stakeholders to translate complex technical challenges into scalable, measurable, and resilient capabilities that uplift security operations.
Throughout his career, he has led high-performing engineering teams, shaped service strategies, and driven innovation across multiple domains. He has headed multidisciplinary customer-facing engineering functions, introduced Agile delivery frameworks to improve service efficiency, and designed scalable security architectures that enhanced SOC performance for organisations across EMEA. His long tenure in senior engineering and solutions architecture roles saw him architect enterprise-grade SOAR solutions that delivered significant operational efficiency, develop internal training programmes to accelerate consultant growth, and present at major industry conferences. A five-time Splunk Trust member, he is widely recognised for his community contribution, technical leadership, and commitment to developing others. Earlier in his career, he supported mission-critical infrastructure for the Galileo satellite programme at the European Space Agency and provided IT services for the UK Ministry of Defence forces deployed globally.
Outside of work, he channels his competitive streak into Historical European Martial Arts, where he competes in Longsword & Messer tournaments and serves as an assistant instructor. When not spending time with his kids, he enjoys weightlifting, gaming, and perfecting the craft of slow-smoked barbecue; pursuits that balance precision, patience, and a love of learning new skills.
