WHY IS PREVENTATIVE SECURITY SO DIFFICULT?

Summary from the TLDR InfoSec newsletter

Security teams should shift from endless vulnerability scanning and detection to preventative tools that stop issues at the source, like using supply chain security tools instead of just identifying vulnerabilities after deployment. Most security vendors focus on data collection and pattern detection rather than systemic prevention, leaving organizations to fix the identified problems manually. The strategy requires getting engineering teams to adopt preventative controls early in development workflows, rather than overwhelming them with vulnerability reports and SLAs that force reactive responses.
