TrustedSec
Elite offensive security firm founded by a former NSA operator, delivering CREST-accredited penetration testing, red teaming, and adversary simulation to Fortune 500 and government clients.
About
TrustedSec is a globally recognised cybersecurity and adversary simulation company advising Fortune 500 companies and government organisations. Founded in 2012 by David Kennedy — a former NSA and Marine Corps cyber warfare operator who has testified before Congress as a cybersecurity expert — TrustedSec has built a reputation for deep offensive security expertise and practitioner-led engagements.
The firm is CREST-accredited for penetration testing and holds PCI QSA qualification through the PCI SSC. TrustedSec's services span penetration testing, red teaming (adversarial attack simulation), social engineering, incident response, and digital forensics. Their red team methodology focuses on training detection and response capabilities, treating each engagement as a learning opportunity rather than simply a compliance exercise.
TrustedSec serves organisations across the technology, financial services, healthcare, automotive, and manufacturing industries, and provides training for the US military's Cyber Protection Teams.
