I You feel good at these all technologies/frameworks and the salary and location are pretty similiar in both of these companies (or You just don't care at the moment about it) I would suggest You to take the 1. offer.

Why?

I'm a webdev and I love building websites. This company build apps using hyped (at the moment) technologies so if something go wrong then You'll find new job easily (I'm getting job offers which requires angular/backbone/cordova experience all the time)

On the other hand, IT security is trending niche, which can be more stable than web development (where market is really huge and dynamic).

But hey, in the end, it's up to You and You should choose wisely what suits You best.
