How to block Instagram from users behind a SonicWall

10/14/2021 26 22404

DESCRIPTION:

Instagram is an online photo-sharing, video-sharing and social networking service that enables its users to take pictures and videos, apply digital filters to them, and share them on a variety of social networking services, such as Facebook, Twitter, Tumblr and Flickr. A distinctive feature is that it confines photos to a square shape, similar to Kodak Instamatic and Polaroid images, in contrast to the 16:9 aspect ratio now typically used by mobile device cameras. Users are also able to record and share short videos lasting for up to 15 seconds.
