Our Story

Yogosha was born out of a fundamental belief that our approach and understanding of cybersecurity was in need of a big shift. Pushing back against the stereotype of shady, dangerous hackers speaking in impossible jargon, we've built a collaborative community of highly trained ethical security experts passionate about helping companies minimize risk and ensure consumer safety.

Through well-written, actionable reports and resources, we're helping teams understand the real impacts and nuances of their cybersecurity strategy, while fairly paying talented security experts for their crucial work. And to further support their work, empower our clients and foster transparency, we’ve also created a sophisticated SaaS solution offering them unparalleled control and visibility over every aspect of their cybersecurity strategy.
