The enterprise security industry is operating with a structural ceiling.
Every major security vendor in your environment runs above the operating system kernel. That was a reasonable architectural choice twenty years ago when the threat model looked different. It has become the ceiling that keeps the industry from making defense materially easier. The attacks that take down Fortune-scale organizations in 2024 and 2025 are operating at layers your agents are loaded after and your firewalls have no visibility into.
This is not a critique of any specific vendor. The incumbent EDR platforms, network appliance leaders, edge providers, and identity suites are competent, well-engineered products built by serious people. They share an architectural position, and that shared position is now the limiting factor on defender outcomes. The question is not whether to replace them. The question is what sits underneath them, and where the industry goes next.
