The ThreatLocker® story. ThreatLocker journey began with a mission to protect businesses from the devastating effects of cyberattacks. Co-founders Danny Jenkins, Sami Jenkins, and John Carolan set out to create solutions designed to eliminate the guessing game of cybersecurity. Danny Jenkins began his cybersecurity career in 1997, which included roles such as managing corporate IT, ethical hacking, and becoming an entrepreneur. A significant turning point occurred when Jenkins witnessed the aftermath of a severe phishing attack. The attack disrupted business operations and nearly resulted in the loss of the company. This incident underscored the critical gaps in existing reactive cybersecurity strategies and motivated Jenkins to develop a proactive, Zero Trust solution designed to give businesses more control over their defenses. With this commitment, along with Sami Jenkins and John Carolan, he co-founded ThreatLocker, making the Zero Trust approach to cybersecurity reality for many. In just a few years, over 50,000 businesses worldwide have embraced ThreatLocker solutions, a testament companies are ready to move beyond the endless game of trying to outsmart cybercriminals and are adopting instead new, proactive ways to defend against them with ThreatLocker redefining Zero Trust solutions.
