Hi, I'm David Nisbet
Security Consultant
Seasoned Cybersecurity Professional and IASME Accredited Practitioner. Expert in securing complex architectures through disciplined manual penetration testing and strategic infrastructure engineering.
The Strategic Advantage
Personal Statement
I excel at bridging the gap between technical defense and organizational compliance. With over a decade of experience across security systems, networking and cyber security, I specialize in manual penetration testing and implementing security frameworks like Cyber Essentials, NIST, and ISO 27001.
My career is defined by a "Security-First" approach. Whether directing operations at NTCyber Ltd or serving in the British Army as an infantry soldier and combat medical technician, I prioritise reliability, discipline and resilience.
I started in CCTV and alarm engineering as NisbetTeknology, moved into networking (Cisco CCNA and Juniper), and grew NTcyber into a full cyber security practice from 2020. I went back to study in 2021 and now focus on web application testing, building my own sites, tools and test automation.
