PeopleSec helps the enterprise get the most cyber value from its people whether they are developers, IT Ops, Sec-Ops, or just employees.
We are enterprise ethical hackers that have talked our way into bank vaults, penetrated top secret networks, applied clinical psychology to change employee behavior, and defended fortune 500 enterprises, again to the root of all security woes, the human element. This is why all of our services have a core theme - “Preparing the human.”
Our ideal clients share our skepticism for tech promises and our passion for pragmatically securing the enterprise. They see compliance mandates as merely the lowest common denominator, not a best practice. PeopleSec helps the enterprise avoid the human errors that cause and worsen all cyber incidents. They all trace back to employees, IT personnel, and software developers.
We transform enterprise employees from soft targets to a vigilant neighborhood watch. We help IT personnel and developers find weaknesses they’ve overlooked, understand what they need to know better and hone what and how to do so. We believe human readiness is achieved through realistic simulations, mass-customized training, meaningful metrics, applied associative learning sciences, and ongoing sustainment exercises.
