In the digital era, web applications are the lifeblood of business operations — powering everything from customer portals to admin dashboards. But with convenience comes risk. Web applications are a prime target for cybercriminals seeking to exploit vulnerabilities, steal data, or hijack user sessions. Understanding and addressing the top vulnerabilities is the first step toward safeguarding your digital assets.
Every click, form submission, and login carries potential risk. Vulnerabilities in your web apps can lead to data leaks, reputation loss, financial damage, and legal consequences. Whether you’re running an e-commerce platform, SaaS product, or business website — attackers are watching, and your defenses need to be airtight.
