How broad do you mean by "in this field" (security specifically, or tech in general)? My very small sample of hiring managers at Google claims that, there, degrees are a pretty significant factor in their decision-making, and a candidate without a degree has to meet a much higher bar before a hiring manager will want to make an exception and consider them despite lacking a degree. So if your previous startup was acquired or you have a significant role in a major open-source project, then yeah, but if you are "just" a good programmer, then maybe not.
I have to believe that an appropriate degree may often be the door-opener that let's you prove all the rest in person. It should also place a floor of sorts on what pay someone can reasonably offer you at various points during your career.
Statistically, having a degree sets you up for ~6-7 figures of extra lifetime income, but you have to bear in mind that such figures account for lots of people who would be marginally employable without a degree. People who can reliably write code, test software, or configure complicated systems aren't marginally employable; they are some of the most employable people in the economy.
