Silent3Cyber tests web applications and APIs for common vulnerabilities, authorization failures, abuse paths, and business-logic weaknesses. Findings are reproducible, prioritized by business impact, and communicated clearly to both developers and leadership.
Architecture and threat review; authenticated and unauthenticated testing; role and authorization testing; input, session, and authentication testing; REST and GraphQL API abuse testing; business-logic review; cloud and container context; and remediation validation.
Executive and developer reports, reproducible evidence, severity and business-impact analysis, remediation guidance, technical debrief, and retest results when included.
Testing runs only during approved windows. Developer coordination and reporting are provided Monday–Friday, 8:00 a.m.–6:00 p.m. Eastern Time. Release-critical work is scheduled through an expedited engagement. A confirmed critical vulnerability is reported within two hours during active testing, and a high-risk vulnerability by the next business day.
The draft report is targeted within five business days after fieldwork ends. A retest is scheduled within 10 business days after a new build, access, and remediation notes are available. Final dates, dependencies, and release constraints are confirmed in the statement of work.
Web applications, REST and GraphQL APIs, browser-based applications, mobile backends, common authentication protocols, cloud-hosted applications, containers, and modern software-delivery environments. Testing methodology aligns with OWASP ASVS 5.0, OWASP testing guidance, and business-logic risk.
Each engagement has a named application-security lead, documented authorization, secure evidence handling, emergency stop procedures, and independent technical review. Application, API, cloud, and development-stack qualifications are matched to the scope and confirmed in the statement of work.
Written authorization; defined application, API, tenant, build, and environment scope; a test environment when feasible; test accounts for relevant roles; API documentation; architecture context; data-handling and rate-limit rules; deployment schedule; developer contact; and approved stop conditions.
Production testing uses the minimum proof needed and avoids intentional access to customer data. Source-code review, software-composition analysis, mobile-binary testing, CI/CD review, and threat modeling are separate scope items unless listed. Silent3Cyber does not certify an application as breach-proof. Client developers own code changes unless remediation engineering is included.
Start with a scoping session to confirm application architecture, user roles, APIs, environments, release timing, sensitive workflows, testing limits, and the desired retest path.
