Web Application Security Testing (VAPT)
(NABL Accredited Security Testing & Certification as per Standards)
Overview
Identify, Fix & Prevent Vulnerabilities in Your Web Applications
Web applications today are the backbone of digital business. They handle sensitive data, financial operations, customer identities, and mission-critical transactions.
A single unnoticed vulnerability can open the door to:Data breaches, Financial & operational loss, Regulatory compliance failures, Reputation damage and customer distrust
DeltaPhi Labs’ Web Application Security Testing combines deep manual assessment with advanced automated scanning to uncover critical vulnerabilities, insecure workflows, broken access controls, authentication flaws, and hidden logic bypasses.
Our testing methodology aligns with OWASP, NIST, SANS, and OSSTMM, ensuring your application receives the highest level of security assurance.
Types of Testing We Offer
Black Box Testing: Simulates a real-world external attacker with no prior knowledge. Ideal for understanding actual exposure.
Grey Box Testing: Uses limited access or credentials to achieve deeper coverage, essential for modern apps with complex user roles.
White Box Testing: Full access to architecture, code, and configurations. Best suited for organizations focused on complete security hardening.
