Red Piranha
At Red Piranha, we came up with a simple concept: a holistic threat protection solution that works. Recruiting a team of experts from the corners of the planet – from engineers to academics to ethical hackers – we worked to develop the most exhaustive and effective security measures on the market. In 2015, we integrated the threat intelligence platform DNS.insure into the development of the Crystal Eye Unified Threat Management systems – a custom suite of software solutions that can be implemented on Red Piranha hardware or on a cloud-based platform. We also manufacture our own made-to-order hardware for the Crystal Eye product range, ensuring top-tier technology and strict quality control. The result? A complex ecosystem of threat management tools that ensures total protection – from prevention and detection to advanced threat intelligence. Our philosophy is clear. End-to-end protection for your enterprise that meets ever-changing compliance regulations – at rates you can afford. We’re committed to offering superior security solutions and services at an accessible price, so even small to medium businesses can enjoy ironclad information protection. Because when our most valuable assets are digital, quick fixes shouldn’t be the status quo – and shrouding them in a fog of confusion shouldn’t be either. At Red Piranha, we believe having the safest, most reliable information security system is everyone’s right – no matter what their background or budget.
