Your experience in security operations is in demand, so that's a big plus for you. Seek work that you can do via external environments, meaning you don't need to be on-site, and don't need to have internal access. Ideally you can create an LLC so you can work for yourself.
A few examples... 1. Doing compliance-oriented security reviews via cloned systems (e.g. your customer provides you with a non-live copy). 2. Advising on process commitments (e.g. security SLAs, or UML/Visio/EA diagrams, or declarative configurations). 3. Effecting security-related project management task plans (e.g. pilots, proof of concepts, research adjuncts, resource estimations).
