PTS Penetration Testing

Industry-grade penetration testing that reveals the security risks your defenses can’t see.

Even with antivirus tools, WAF protection, and Multi-Factor Authentication (MFA) in place, many organizations still suffer security breaches. The issue is rarely the number of tools deployed—it’s that those defenses were never truly tested. Penetration Testing exists for this exact purpose. By simulating real-world attacks, it verifies whether your security controls can actually withstand a determined adversary.

What Is Penetration Testing?

Penetration Testing is a structured, authorized security assessment where professionals simulate cyberattacks against your systems. The process includes:

Exploiting known and unknown vulnerabilities (e.g., SQL Injection, XSS)
Attempting to bypass existing security controls (WAF, antivirus, MFA)
Assessing the likelihood and impact of a successful attack
Recommending practical fixes to strengthen your overall security posture

Three Key Benefits of Penetration Testing

Penetration Testing validates your defenses from a real attacker’s point of view, uncovering risks across on-premises, cloud, and hybrid environments—without the cost of building your own red team.

Identify high-risk vulnerabilities that scanners miss

Realistic attack simulations uncover misconfigurations, authorization flaws, and chained vulnerabilities that automated tools cannot detect.

Clear risk prioritization to guide remediation

Instead of a long list of issues, you get clarity: Which vulnerabilities are truly exploitable? What’s the potential damage? Where should you focus your efforts first?

Strengthen compliance and customer trust

Demonstrate security maturity with testing aligned to ISO 27001, PCI DSS, GDPR, and other global standards—ideal for audits and supply-chain requirements.

Testing Scope

Our methodology aligns with OWASP standards for application testing and includes comprehensive assessment of system, network, and cloud environments.

Application Security

Validation of session management, encryption, and connection handling
Authentication & authorization testing
Input validation checks (XSS, SQLi, Command Injection, etc.)
Application logic and error-handling review
Business logic flaw identification and risk evaluation

System / Infrastructure

Vulnerability scanning of external services (Web, Mail, FTP, RDP, etc.)
OS and network device configuration review
Protocol and certificate strength analysis
Password policy assessment and brute-force simulation

Cloud / Mobile

Cloud storage and API security configuration review
Mobile application (App) vulnerability assessment
Third-party library & dependency security review

Penetration Testing vs. Vulnerability Scanning

Item	Penetration Testing	Vulnerability Scanning
Execution	Manual in-depth testing + tools	Fully automated scanning
Depth	Validates real exploitability	Identifies known issues only
Coverage	Business logic, permissions, chained flaws	Technical vulnerabilities, versions
False Positives	Very low	Higher (automated)
Report	Attack paths + risk analysis + remediation plan	Vulnerability list + basic guidance
Frequency	Quarterly / Semi-Annual / Annual	Weekly / Monthly
Best For	Compliance & critical system validation	Routine checks

Penetration Testing Process

Effective penetration testing follows a structured process—not just a quick scan. Our security team provides complete visibility and actionable results.

Step1 Requirement Analysis

We review your business model, architecture, and compliance needs to define a tailored testing scope that aligns with your environment.

Step2 Test Planning & Execution

Senior testers simulate real-world attack tactics to evaluate your systems thoroughly—without disrupting operations.

Step3 Reporting & Review

You receive a detailed report outlining findings, attack demonstrations, risk ratings, and prioritized recommendations.

Step4 Remediation & Re-testing Support

We offer guidance on fixing vulnerabilities and can conduct follow-up tests to confirm that remediation is effective.

Is Your Organization Ready for Penetration Testing?

Penetration Testing is recommended for any organization that relies on digital services—especially those with complex systems or compliance requirements. You should schedule a test when:

◎ Launching a new website, system, or mobile app

◎ Implementing or maintaining ISO 27001, PCI-DSS, GDPR, or similar frameworks

◎ Working with government or supply-chain partners that require third-party validation

◎ Recovering from a security incident

◎ Expanding your environment, increasing your external attack surface

FAQ – Penetration Testing

How often should penetration tests be performed?

At least once per year is recommended. Additional tests should be scheduled after major system changes, permission updates, or security incidents. Some industries—such as finance—require one or two tests annually depending on regulatory guidelines.

What’s the difference between penetration testing and vulnerability scanning?

Vulnerability scanning is automated and identifies known weaknesses but cannot confirm if they are exploitable. Penetration Testing uses human expertise to simulate real attack behavior, uncovering logical flaws and chained vulnerabilities that scanners cannot detect.

Will penetration testing disrupt normal operations?

No. Testing is conducted under strict control and planned carefully to avoid any destructive actions or downtime.

What reports will I receive?

You will receive a full technical report detailing each finding, its CVE/CWE reference, risk rating, potential impact, and recommended fixes. These reports meet the needs of government tenders, supply-chain audits, internal reviews, and ISO compliance processes.

Traditional security tools can’t confirm whether your defenses can truly withstand an attack.

Modern organizations need proactive, validated security assurance.

Penetration Testing gives you the most reliable, real-world evaluation of your security posture. Identify hidden risks before attackers find them—and let Yuan Jhen be your trusted security partner.

If you’re launching new systems, preparing compliance submissions, or adopting ISO 27001, PCI-DSS, or GDPR, our consultants can deliver a complete testing and reporting package.
