Modern web applications face increasingly sophisticated threats—from SQL injection and broken authentication to API abuse and logic flaws. Osto's Web Application Penetration Testing Services deliver deep, manual-and-automated security assessments to uncover hidden vulnerabilities before attackers do, giving your team the clarity and remediation guidance needed to strengthen defenses and maintain business continuity.
Comprehensive security assessments covering every layer of your web applications, APIs, and cloud-connected surfaces.
AI-powered scanning with machine learning algorithms that categorize vulnerabilities by severity, identify the most targeted areas of your web applications, and deliver step-by-step remediation guidance to close security gaps fast.
End-to-end Vulnerability Assessment and Penetration Testing delivered as a managed service, combining automated discovery with expert manual testing to surface critical risks across your entire web application estate.
Real-time threat detection and prevention for web apps and APIs using OWASP Top 10 detection, DDoS protection, bot mitigation, and SQL injection blocking—ensuring only legitimate traffic reaches your origin servers.
Intelligent traffic profiling that uses machine learning to analyze behavioral patterns, detect anomalies, and continuously adapt your web protection posture against evolving attack vectors.
Integrate security testing early in the software development lifecycle to catch vulnerabilities at the source, reducing remediation costs and ensuring applications are secure before they reach production.
AI-powered security questionnaire agent that responds to vendor and compliance security questions accurately and efficiently, accelerating your security review process and demonstrating due diligence to stakeholders.
We work with your team to define the testing scope—target URLs, APIs, authentication flows, and business-critical functionality. Passive and active reconnaissance maps the attack surface, identifying all exposed endpoints and technology fingerprints before active testing begins.
