Since this comes up whenever there is a Project Zero article, here is a summary I made in summer 2020 on the distribution of the bugs they find/report: Since this always comes up, here's an overview I made several weeks ago about where Project Zero focuses their efforts: All counts are rough numbers. Project zero posts: Google: 24 Apple: 28 Microsoft: 36 I was curious, so I poked around the project zero bug tracker to try to find ground truth about their bug reporting: https://bugs.chromium.org/p/project-zero/issues/list https://bugs.chromium.org/p/project-zero/issues/list For all issues, including closed: product=Android returns 81 results product=iOS returns 58 vendor=Apple returns 380 vendor=Google returns 145 (bugs in Samsung's Android kernel,etc. are tracked separately) vendor=Linux return 54 To be fair, a huge number of things make this not an even comparison, including the underlying bug rate, different products and downstream Android vendors being tracked separately. Also, # bugs found != which ones they choose to write about.
