Companies like xbow and horizon are using agents that talk to symbolic tools to automate more red teaming flows for different domains, so very much so. As shown in my talk, modern models are quite capable, and they aren't doing investigation-level scenario depth, more like scans, so seems like becoming the new expectation that everyone can & will do.
Companies like trail of bits are more interesting to me here, because they historically do deeper analysis. A place to look there is the darpa cc x ai (?) competition that finished at blackhat last year.
If in the US, we may be looking for a pen testing partner on an upcoming agentic AI contract, so feel free to msg - Leo @ graphistry
