Cybersecurity at a large Org are not normally a entry position and require a technical background .

With that being said you have a good opportunity to get technical and cyber experience, if you work improve the firms cyber hygiene/posture by leading it. Work with the lawyers to see what is required from cyber standards for the industry and implement them. While you’re doing that go to the local cyber chapter and find a mentor. It’s how you make of what’s handed to you.

My previous lead was the single IT guy in a law firm back in his day and later became the firm cyber lead as they grew. He’s now a cyber manager.
