Blogs, both company-authored and personal, are great ways to get keyed into new resources and methods from an informed source who you trust to curate the news you care about. The blogs we're including here focus more on pentesting and bug bounty participation than infosec or cybersecurity, generally. Though there are a lot of great blogs by industry experts —such as Bruce Schneier's Schneier on Security or Brian Krebs' Krebs on Security —that can be counted upon for rigorous, technically-informed articles on popular security topics, providing a thorough accounting of those sort of general infosec outlets is beyond our scope.
