Application Security Testing from Vietnam | TMA Solutions

As the demand for security testing continues to grow, businesses may find it difficult to balance internal resources, costs, and quality requirements. In this situation, application security testing from Vietnam is becoming an option worth considering because of Vietnam’s strong technology workforce and competitive costs.

With more than 29 years of experience in software development and processes based on international standards, TMA Solutions provides software testing and development services with a focus on security, quality, and scalability.

1. Why choose application security testing from Vietnam?

Working with a security testing provider in Vietnam can bring clear advantages in both cost and resources. However, businesses should still carefully check the provider’s real project experience and technical capabilities.

Lower costs than the US/EU while maintaining comparable quality

Thanks to lower operating and labor costs, security testing services in Vietnam can cost 40–60% less than in the US and EU markets. These savings can make it easier for businesses to maintain a long-term security team instead of depending only on short-term contracts.

Even with competitive pricing, service quality can still meet international standards through experienced engineers and strict quality control processes.

A large and growing security engineering workforce

The rising demand for cybersecurity requires professionals with skills in secure coding, penetration testing, and SOC monitoring.

With a strong technology industry that includes 74,000 companies and more than 1.2 million workers, according to the Ministry of Science and Technology, Vietnam has a strong ability to train and scale technology teams quickly.

This workforce is expected to continue growing under Vietnam’s digital workforce development strategy toward 2030.

A time zone that supports both APAC and Europe

Vietnam is in the UTC+7 time zone, which makes it easy to work directly with APAC markets and handle tickets or incidents during the same working day.

At the same time, the overlap in the afternoon supports smooth handovers with European partners.

Vietnam is only around 1–2 hours apart from many APAC markets and around 5–7 hours ahead of Western Europe, helping teams create a continuous workflow and reduce technical delays.

English skills that support international projects

In security projects, English is important for understanding requirements, reviewing system architecture, and preparing vulnerability reports.

Good English skills help teams process tasks faster and reduce misunderstandings about technical requirements.

4. Security, compliance & data protection standards

A strong security system should follow recognized international standards. At TMA Solutions, these standards form an important foundation for security methods and risk control across projects.

• OWASP ASVS: OWASP Application Security Verification Standard (ASVS) is an application security standard developed by OWASP. It provides a base for defining security requirements and checking secure application architecture. ASVS helps development and testing teams define the right security level during application design, development, and testing. It also helps software protect against common vulnerabilities.

• OWASP MASVS: OWASP Mobile Application Security Verification Standard (MASVS) focuses on security risks in mobile applications for iOS and Android. It covers areas that traditional web security standards may not fully address. MASVS can be used to check: mobile source code security, local data storage, authentication methods and encryption.  This helps protect users from security risks on mobile devices.

• NIST SP 800-218 (SSDF): NIST SP 800-218, also known as the Secure Software Development Framework or SSDF, is guidance from the US National Institute of Standards and Technology. It focuses on adding security to every stage of the Software Development Life Cycle (SDLC). This approach helps reduce software vulnerabilities from the early design and coding stages.

• ISO/IEC 27034: ISO/IEC 27034 is an international standard focused on application security. It provides a management framework that helps organizations add security to their software development processes.

• CIS Control 16: CIS Control 16 is one of the important cybersecurity controls from the Center for Internet Security. It focuses on managing the application development life cycle and protecting applications from design and development to testing and deployment. The goal is to reduce common application weaknesses.

• PCI DSS: Payment Card Industry Data Security Standard (PCI DSS) is required for organizations that process, store, or transfer payment card information. Its main goals are to reduce fraud and protect customer payment data. For e-commerce and payment software, PCI DSS is an important standard to follow.

• SANS: SANS provides cybersecurity research, guidance, and information about dangerous software weaknesses. These resources help software engineers understand common vulnerabilities and learn how to avoid them.

• OSSTMM: Open Source Security Testing Methodology Manual (OSSTMM) provides a methodology for penetration testing. It supports a more structured and objective way to measure and assess security by using measurable indicators instead of only listing security problems.

5. Security testing projects executed by TMA 

Below are several security testing projects that show TMA Solutions’ experience in solving technical security problems and protecting real-world systems.

5.1. Embedding Static Application Security Testing (SAST) into a JenkinsBitbucket Pipeline

The client is a leading cybersecurity company in the United States. The company provides enterprise email and web security solutions. Its main system is a cloud-based isolation platform. The platform helps prevent malware, ransomware, and phishing attacks. It also plays an important role in the client’s Zero Trust architecture. 

Security challenge

The client had difficulty keeping the same secure coding standards across different development teams. The source code review process was manual and had little automation. This slowed down software releases and increased security risks.

Developers also had limited information about security issues in Pull Requests. As a result, new teams needed more time to understand and follow the company’s security standards. 

Testing scope

• Integrate SonarQube with Jenkins and Bitbucket to automate Static Application Security Testing (SAST) in the CI/CD pipeline.

• Create reusable Jenkinsfile templates with a SAST stage. Apply branch-specific rules and Quality Gates to maintain secure coding standards.

• Set up a central SonarQube project structure and connect it with Bitbucket repositories. Adjust scanning rules to reduce false positive alerts.

Operational results

• Faster processing: Developers received inline feedback and automatic reports in less than 5 minutes. This improved the speed of information delivery by 30%. New teams and services could also complete onboarding in less than one day because they used standard templates.

• Remediation impact: Post-merge vulnerabilities dropped by 60%. The system stopped code with security issues before it reached the production environment. This helped improve the client’s security process while keeping software development fast.

5.3. Pentest for Carrier VoIP Provisioning Portal

The client is a large telecommunications company in North America. Its main platform is a Carrier VoIP Provisioning Portal Server. This secure web platform manages subscriber settings, devices, and telecom service resources.

Security challenges

The client needed a full penetration test for its public-facing portal. The main goal was to find technical weaknesses before attackers could use them for unauthorized access or data theft.

A serious vulnerability in this platform could affect the integrity and availability of the telecom network.

Testing scope

• Method and approach: TMA engineers used a Black Box testing approach. They tested the web application from the view of an external attacker.

• Testing tools: The team used Nmap to scan networks and ports. Nessus helped find configuration issues and known CVEs. Burp Suite Professional was used to analyze and modify HTTP requests.

• Testing process: The team first used Nmap to find services on ports 443 and 80. Nessus then checked for outdated libraries such as Prototype.js and jQuery. After that, Burp Suite Pro was used to inspect sessions, test hidden endpoints, and map attack vectors such as path traversal and user enumeration.

Operational results

• Vulnerability identification: The test found several critical security issues. Outdated third-party JavaScript libraries, including jQuery 1.7.2 and Prototype.js 1.6.1, created risks such as XSS and DOM injection. The scan also found exposed configuration files and metadata. PHP error messages showed technical information. Some HTML comments also contained links to old administration pages.

• Remediation impact: The pentest showed the client’s real exposure surface. It gave the client a clear view of vulnerable components. Based on these findings, the client could fix configuration problems, reduce the attack surface, and improve protection against security threats.
