One thing we are observing is that organizations are actively seeking out solutions to better manage their security data operations. Until recently, they have been aggressively repurposing common data and observability tools. I believe that this is a stop-gap measure because there was no alternative. But now there is a growing ecosystem of security data operations tools to support the modern security data stack. Ross Haleliuk's epic article lays this out at length.

In this article I am explaining the underlying design principles for developing our own data pipeline engine, coming from the perspective of security teams that are building out their detection and response architecture. These principles emerged during design and implementation. Many times, we asked ourselves "what's the right way of solving this problem?" We often went back to the drawing board and started challenging existing approaches, such as what a data source is, or what a connector should do. To our surprise, we found a coherent way to answer these questions without having to make compromises. When things feel Just Right, it is a good sign to have found the right solution for a particular problem. What we are describing here are the lessons learned from studying other systems, distilled as principles to follow for others.
