To all the dreamers, the doers and believers. Go for it - Trust. Share. Discover. The future is safe.

Our company is about trust, about safety, about protecting the freedom of privacy and preparing for the future of innovation. Because of that belief, we have started the journey to expand mobile security and provide the world with it. We are driven by economic impact yet the future of our children is what we care about the most. If we talk about mobile application intelligence, we are talking about an issue we all have. We all need a solution to this. Outside of the company walls we all live a mobile lifestyle and we all need a secure environment.

We had significant help in actualizing this company. G+D have been valued partners in our founding phase in 2018. They have extended the financial support for our launch and we have benefited greatly from the truly global perspective on mobile security hardware.
