Overview
Security testing identifies vulnerabilities in your software systems before attackers do—validating that your application, APIs, infrastructure, and business logic can withstand real-world attacks. At NextGen Coding Company, our US-based security engineers conduct penetration testing, vulnerability assessments, code security reviews, and DAST/SAST analysis to find and help you remediate the weaknesses that put your data and your customers at risk. Security testing is not optional for any application that handles sensitive data, processes financial transactions, or has regulatory obligations—it is the mechanism by which you verify that your security controls actually work. Our team brings practitioner-level offensive security expertise combined with deep application development knowledge to find vulnerabilities that automated scanners miss.
Why Choose NextGen Coding Company
Security testing from NextGen is conducted by engineers who have built the systems they are testing. This makes a fundamental difference: our testers understand application architectures, authentication flows, business logic, and the subtle implementation details that automated tools cannot reason about.
Our security engineers hold degrees from Columbia, Harvard, and Oxford and have conducted security assessments and built security systems at Apple, Citi, and Wells Fargo. They approach security testing with an attacker's mindset and a developer's understanding—combining the creativity to find novel attack paths with the technical depth to understand root causes and develop fixes.
We produce security testing reports that are actually useful to development teams: clear vulnerability descriptions, proof-of-concept reproduction steps, CVSS scores, and specific remediation guidance. We then work with your team through remediation, retesting fixed vulnerabilities and confirming that fixes are effective.
All testing is conducted by US-based engineers under US legal frameworks, with appropriate engagement agreements that protect both parties.
Who Should Use Our Services
Security testing from NextGen serves organizations at every stage of their security maturity journey.
Pre-Launch Applications
— Applications handling user data should undergo penetration testing before launch. We identify vulnerabilities before they reach production users.
Applications Undergoing Compliance Certification
— SOC 2, PCI-DSS, HIPAA, ISO 27001, and CMMC all require or strongly recommend penetration testing and/or vulnerability assessments. We produce testing documentation that auditors accept.
Applications With Recent Significant Changes
— Major feature releases, architecture changes, and cloud migrations introduce new attack surfaces. We conduct targeted security testing aligned to the changed scope.
Organizations Following a Security Incident
— Post-breach security testing identifies whether additional vulnerabilities exist and validates that breach remediation was effective.
Development Teams Implementing DevSecOps
— Organizations integrating security into CI/CD pipelines need SAST and DAST tooling selection, configuration, and tuning. We implement and optimize automated security testing.
Organizations Requiring Annual Penetration Testing
— Many compliance frameworks and enterprise customer requirements mandate annual penetration testing. We provide repeatable, thorough annual testing programs.

Our Process
Scoping and Rules of Engagement
We define the scope of testing—applications, APIs, IP ranges, testing types—and agree on rules of engagement including testing windows, notification procedures, and off-limits systems. This is documented in a formal engagement agreement.
Reconnaissance and Attack Surface Mapping
For penetration tests, we conduct systematic reconnaissance to map the attack surface: all endpoints, authentication mechanisms, technology stack, and integration points. Understanding what can be attacked before attempting to attack it.
Vulnerability Discovery
We conduct active security testing using both automated tools and manual techniques. Automated tools provide broad coverage; manual testing finds business logic vulnerabilities, authentication bypasses, and authorization flaws that tools cannot discover.
Exploitation and Validation
For penetration tests, we attempt to exploit identified vulnerabilities to demonstrate their real-world impact—escalating privileges, accessing unauthorized data, or executing unauthorized operations. This distinguishes confirmed findings from theoretical vulnerabilities.
Reporting
We produce a security testing report covering executive summary, findings sorted by severity, reproduction steps, CVSS scores, and specific remediation guidance. We deliver a technical briefing to your development and security teams.
Remediation Support and Retesting
We work with your team through remediation, providing guidance on fixes. After remediation, we retest all findings to confirm they are fully resolved and issue a remediation verification report.
Pricing
Security testing services are priced based on scope, testing type, and depth of assessment required.
**Web Application Penetration Test** — Fixed-fee or scope-based pricing for application penetration tests. Pricing reflects the complexity of the application and the testing depth required.
**API Security Assessment** — Targeted assessment of REST or GraphQL API security. Priced based on API surface area.
**Annual Penetration Testing Program** — Recurring annual program providing consistent testing scope, trend tracking, and compliance documentation. Retainer pricing available.
**SAST/DAST Implementation** — Fixed-scope engagement deploying and tuning automated security testing tools in your CI/CD pipeline.
**Cloud Security Assessment** — Penetration testing of cloud infrastructure including IAM, network, storage, and service configuration.
**Developer Pod Security Engineering** — Embed dedicated US-based security engineers via our pod model for ongoing application security testing and developer security support.
All engagements are documented with engagement agreements and scope of work. Contact us for a custom quote.
