The High Cost of Security Bugs

Security bugs like Cloudbleed highlight the critical importance of secure coding practices and robust incident response. Even minor flaws can lead to major data leaks, reputational damage, and legal repercussions. Without proper training, your team may be unprepared to handle similar incidents effectively, leading to delayed responses and increased impact.
