What's the salary benchmark for DevSecOps lead with 10 years experience?

The 'Sec' part of that job title is just not going to move the needle when it comes to salary. Companies talk a good game when it comes to devops security and 'shifting left' but few, if any, will actually pay for it up front and instead will just use it as an additional feature when selecting among various candidates for open roles. Just look for any devops engineer data and hope that by playing up security experience you might be able to bump your ask 5-10%.

Non-tech company:

~$100k-$180k base + ~5%-10% cash bonus

Small / private tech company:

~$120k-$200k base + ~5%-20% cash bonus or ~20%-50% "Monopoly" money RSU

Publicly traded tech company:

~$140k-$220k base + ~20%-50% RSU

FAANG: The sky is the limit

U.S. Salaries

I expect location and size/type of business (faang, startup, etc) may give wildly different answers, on top of experience

Likely 190+ is the going rate. I see In upper echelon markets 225-250

Companies which actually do DevSecOps are unlikely to have roles with that title.

Which country/region? Big difference between, say, Bay Area and Bratislava.
