The document discusses security concerns for startups with web applications. It notes that web infection attacks and malware seeding on legitimate websites have increased significantly. Startups with user-generated content or that trust user inputs are vulnerable if developers do not understand vulnerabilities like SQL injection, cross-site scripting, and cross-site request forgery. The document recommends educating developers on secure coding practices, implementing security testing to cover the OWASP Top 10 vulnerabilities, and addressing website security as it makes good business sense and is necessary to maintain trust with online users.
