Hey folks, I’ve recently launched a small web app for my business and now I’m getting nervous about security. I keep hearing about SQL injections, XSS attacks and other vulnerabilities that can compromise not only data but also customer trust. I don’t have much experience in penetration testing or cyber security. How do you guys usually check whether your web app is safe? Do I need some specialized service, or is there a DIY way to do this? Any advice from those who’ve gone through this would be awesome.
