This patent portfolio covers foundational cybersecurity technologies for isolating untrusted web code to prevent malware, ransomware, and zero-day exploits from reaching user endpoints. The inventions protect systems and methods that execute web content in isolated environments, generate safe graphical renderings of renderable content, and deliver those renderings to users without exposing underlying executable code. The portfolio further includes techniques for intermediate and hardware-based isolation using embedded systems, image capture, and secure rendering pipelines that preserve full browser interactivity while enforcing strict code separation. With priority dating back to 2010, these technologies represent core infrastructure IP underlying modern remote browser isolation, zero-trust security, and secure web access solutions, and present a strong licensing or acquisition opportunity for cybersecurity vendors, cloud security providers, and enterprise endpoint protection platforms.
