It's vastly male dominated, so you could argue that if there's discrimination against men it's not very effective. Probably there's discrimination for and against women, and for and against men, in all sorts of ways.
But I'd bet that discrimination against hiring men into a tech position is probably the norm.
I talked with some hiring managers about this a few years ago. About 5 years ago, female devs with an undergrad degree made up less than 20% of the available hiring pool. There's a preference to hire female developers, but finding them is incredibly difficult - which is partly why there's a preference. I wouldn't call that discrimination in hiring when it's simply trying to balance a dev team that's 4/5ths males.
