Are platonic male friendships possible for a wife once this has happened?

My wife and I have had a good marriage for 10 years. She has always had mostly male friends and does not get along with women as well. I have always known this and so never opposed her having guy friends. Last summer she got too close to one of her guy friends. Nothing physical happened, but she did lie to me about how they had flirted and he made clear what he wanted from her. When I found out, she distanced herself from him. This has not happened before and she was very sorry about the whole thing. For me the problem was the lying and not the friendship or even the flirtation. We have talked about it all quite a bit and I have said I want her to continue being friends with men. I do not want to control her and I do not want her to change her whole life due to one potential mistake. Did I handle this correctly? Can things go back to how they were or should she avoid male friendships going forward? Opinions and advice are very much appreciated.
