Privoro
We started Privoro in 2013 not merely as a company, but as a movement. One driven by a simple philosophy: that security and privacy need not be casualties of our hyper-connected, sensor-driven, mobile-first world. Simply put, your information is yours alone, and you should be able to control how it is accessed and shared. Fast-forward to today. Smartphones are not only front and center of our digital lives, but the focus of an intense battle for our information – from cybercriminals looking to get their hands on our most important details to advertisers looking to target us based on our digital footprints. It’s clear that this battle won’t be won with conventional solutions. Or by making compromises. Or even by working within existing systems. No, to reclaim privacy and take back control over our digital lives, we had to fundamentally rethink mobile security. And with SafeCase, our second-generation smartphone security case, we believe that’s what we’ve done. As an external, high-security source of trust, SafeCase surrounds – but is functionally independent of – a user’s mobile device. The case’s features insulate it from the vulnerable mobile ecosystem. Enterprises and government agencies can utilize the SafeCase for mobile protections without having to depend on the smartphone. Even when the mobile device has been compromised, the SafeCase builds a baseline of trust for the broader system. While SafeCase can be used by organizations for a variety of use cases, counter-surveillance protection is a core functionality. The case blocks the host smartphone’s cameras and actively jams each of the microphones with randomized noise. Privoro believes that only physical, verifiable protections can overcome the threat of hijacked smartphone sensors targeting national security agencies, publicly traded companies and high-profile individuals. Privoro. Protecting the most important information in the world – yours.
