Opticca Security DAST (Dynamic Application Security Testing) is a security testing service that examines web applications and APIs from the outside, simulating the perspective of an external attacker without requiring access to source code. The service tests running applications by probing the same interfaces an attacker would use, enabling detection of vulnerabilities that may be missed by other testing methodologies such as SAST or manual code review. It is language-agnostic, meaning it does not require knowledge of the underlying programming language or framework of the application being tested. DAST testing is integrated into the software development lifecycle (SDLC) as early as the build phase, allowing teams to identify security risks without relying solely on lengthy penetration testing engagements. It is designed to cover complex application architectures, including those involving microservices, APIs, and modern frameworks. The service is oriented toward reducing false positives by reporting only vulnerabilities that represent confirmed, real-world risks. It also assists with compliance requirements such as PCI DSS and other regulatory reporting, and can surface configuration flaws and user experience issues. Opticca Security positions this offering as a consulting and managed service, helping organizations select, deploy, and manage DAST tooling as part of a broader application security program.
