First time I noticed Data Services on github repo and was so impressed with its Security alerts service. It’s free as of now, but I can kinda see where it may go… (cough cough blackduck… or a similar paid service)
Nonetheless, since I turned on Security alerts on some of my personal repos I have received so many emails warning about security vulnerabilities that exist in those repos. Also, there is another feature that github automatically submits a PR to fix the issue for you.
