The Net
Angela Bennett is a freelance computer systems analyst who tracks down software viruses. At night she hooks up to the internet and chats to others 'surfing the net'. While de-bugging a new high-tech game for a cyber friend, she comes across a top secret program and becomes the target of a mysterious organization who will stop at nothing to erase her identity and her existence, in order to protect the project.

Good enough of a watch, might watch again, but can't honestly recommend.
The biggest problem is just that the movie is dated. The entire movie is based off a fear mongering joke/concept that our lives are controlled by computers, which in 1995 wasn't really the case, but in 2020 is much more true in the way that the movie wants to say.
What actually makes the movie is that the movie isn't centered on manipulating the information, but uses it as adversity that the protagonist can overcome.
Essentially this comes down to a "average person" in a "spy movie" trope. I think puzzle fans will like this one as it is a lot of "If X and Y, then what do you do?". And we know Sandra Bullock doesn't shy away from a little action.
