Cybersecurity is entering a breaking point where quantum computing, shadow AI, and architectural failures are reshaping how organizations must defend their data. In this episode of Tech Field Day Takeaways from Security Field Day 15, Tom Hollingsworth explores the next major shifts in cybersecurity, including the urgent rise of post-quantum cryptography, the importance of building security into platforms from the start, and the growing challenge of shadow AI in enterprise environments. He highlights how “harvest now, decrypt later” attacks are already shaping risk models, why organizations need architectural security thinking instead of bolt-on tools, and how companies like Fortinet are addressing AI governance and data protection. It’s a forward-looking look at how security teams must adapt before these threats fully mature.
