Are Continental tires suitable for winter driving conditions?

I've been a loyal customer of Continental tires for years and have always been impressed with their performance in various driving conditions. However, as winter is approaching I'm starting to wonder if their tires are suitable for snowy and icy roads. I've done some research but couldn't find any definitive answers, which made me think that it's worth asking the community here. Do Continental tires provide sufficient grip and traction on snow and ice? Are there any specific models or features that make them more winter-friendly?
