# Danny Jenkins

> Danny Jenkins is the British-born, Orlando-based CEO and co-founder of ThreatLocker, a cybersecurity company he launched in 2017 with Sami Jenkins and John Carolan. His career began with an IT apprenticeship as a teenager and grew through corporate IT, ethical hacking and incident response. A ransomware disaster at a client convinced him that security should default to blocking unapproved activity rather than trying to recognize every new threat. That idea became ThreatLocker's operating thesis, and by July 2026 the company said it protected more than 70,000 organizations worldwide and had raised a $190 million Series F for product development and international expansion.
