What is Thick Client Security Testing?
Application security testing is the structured process of identifying and validating security vulnerabilities in web applications, APIs, mobile apps and desktop software before attackers find and exploit them. Modern applications are complex, multi-layered systems where vulnerabilities span authentication, session management, input handling, business logic, API design and third-party integrations. Automated scanners catch only a fraction of real vulnerabilities; deep manual testing by experienced consultants is essential to find the flaws that matter.
Codesecure delivers application security testing under signed NDA with a fixed-price proposal within 24 to 48 hours. Our consultants hold OSCP, CEH and CISSP certifications and follow OWASP Testing Guide, ASVS Level 2 and the OWASP API Top 10. Our ISMS is ISO/IEC 27001:2022 certified. Every finding is manually verified with a working proof-of-concept, and a free retest is included for all critical and high-severity findings after your team remediates them.

Our Application Security Testing Methodology
Every application security engagement follows a 5-phase methodology aligned with OWASP Testing Guide, ASVS, OWASP API Top 10 and OWASP Mobile Top 10:
1
Reconnaissance and Threat Modelling
Application architecture review, technology stack fingerprinting, attack surface mapping and threat modelling to identify high-value targets including authentication flows, payment logic and data handling functions.
2
Automated and Manual Testing
Authenticated and unauthenticated testing using both automated scanners and deep manual techniques. We test business logic, chained vulnerabilities, IDOR, XXE, SSRF and race conditions that scanners miss.
3
Exploitation and Impact Demonstration
Controlled exploitation of confirmed vulnerabilities to demonstrate real impact: data extraction, account takeover, privilege escalation and bypass of security controls. Evidence captured with full PoC details.
4
Reporting and Developer Walkthrough
CVSS-scored findings with line-level code references, PoC steps, remediation guidance per tech stack and OWASP/ASVS mapping. Live walkthrough with developers to ensure findings are understood and fixed correctly.
5
Free Retest
After remediation, we retest all critical and high findings at no extra cost and issue a closure report with before-and-after evidence, accepted by SOC 2, ISO 27001 and PCI DSS auditors.

Compliance Frameworks Requiring Application Security Testing
Application security testing is mandated by multiple regulatory and industry frameworks. Our reports are structured to provide the technical evidence each standard requires from your auditors:
OWASP ASVS and Testing Guide
OWASP Application Security Verification Standard provides a comprehensive testing framework for web and API security. Our engagements follow OWASP ASVS Level 2 by default with Level 3 available.
PCI DSS v4.0 requires secure development practices (Req 6) and annual penetration testing of applications handling cardholder data (Req 11). Our reports satisfy both requirements.
ISO 27001:2022 Annex A Section 8 covers secure development, testing and change management controls. Our application security assessments provide direct evidence for A.8.25 through A.8.31.
SOC 2 Trust Services Criteria require detection and monitoring of application vulnerabilities. Our testing provides CC7.1 technical evidence that vulnerability management controls operate effectively.
GDPR Article 25, Privacy by Design
GDPR requires data protection by design and default in all applications handling EU personal data. Our application security testing identifies data exposure, authentication and access control gaps affecting GDPR compliance.
DPDP Act 2023
India's DPDP Act requires data fiduciaries to implement reasonable security safeguards in all applications processing personal data. Our application security assessments satisfy this obligation with documented evidence.
Frequently Asked Questions
What is the difference between Vulnerability Assessment and Penetration Testing?
Vulnerability Assessment (VA) uses automated tools to systematically identify and catalogue known security weaknesses. Penetration Testing (PT) goes further: a consultant manually exploits those weaknesses, and others, to demonstrate real business impact. Thick Client Testing combines both to give you a complete picture of your security posture, from a broad scan to targeted attack simulation.
How often should Thick Client Testing be conducted?
At minimum once a year, and after any major infrastructure change, application release or new deployment. Internet-exposed applications handling customer or payment data should be tested quarterly. RBI-regulated entities (banks, NBFCs, payment aggregators) face more frequent requirements. Many organizations now run a continuous model with quarterly deep tests plus on-change validation.
