The fifteenth edition of the Lonestar Application Security Conference (LASCON XV) in Austin brought together 450 attendees and 52 speakers who explored the complexities of application security in a rapidly evolving technological landscape. Central themes included the importance of connecting cybersecurity signals to business context and human judgment, the emergence of Identity Threat Detection and Response (ITDR) as identity becomes the new security perimeter, and the necessity of embedding automation within development workflows to reduce false positives. The conference highlighted the shift towards risk-based vulnerability management with an emphasis on remediation rather than mere scanning, and the evolving role of AI in application security, which presents both opportunities and challenges. Speakers emphasized the need for context-driven prioritization, alert deduplication, and the integration of AI tools, while maintaining human oversight, to effectively manage and mitigate cybersecurity risks in production environments.
