Overview : PCI DSS Compliance

PCI DSS (2004) is a global standard mandating security controls for organizations handling cardholder data (CHD) within the Cardholder Data Environment (CDE). It applies to merchants, processors, acquirers, and even some vendors handling CHD on their behalf. Compliance requires implementing controls across six core objectives to safeguard CHD. Use the Self-Assessment Questionnaire (SAQ) to determine your organization’s specific PCI DSS requirements


Major payment brands address transaction data security concerns. They’ve
collaborated to define requirements and checklists protecting CHD (PAN, name, expiry, service code) & SAD (track data, CVC, PINs) to mitigate data breach risks.

Annual Validation Requirement

Organizations are required to complete a PCI validation form annually, regardless of how they accept card data.

Secure Data Storage

Companies must define the scope of their cardholder data environment (CDE) if they handle or store credit card data

Card Data Handling

This involves managing the intake of credit card data from customers, including securely collecting and transmitting sensitive card details

Enforce pre-defined secure configurations (baselines) for all systems.

Safeguard stored account data with encryption and access controls

Secure cardholder data in transit with robust cryptography.

Deploy comprehensive anti-malware defenses to protect systems and

Implement secure development practices throughout the system lifecycle

Grant access to system components and cardholder data based on least

Employ robust user identification and authentication for system access.

Secure physical access points to safeguard cardholder data.

.Continuously monitor and log all access attempts to systems and cardholder data

Perform regular penetration testing and vulnerability assessments.

Integrate security policies and programs to establish a robust information security posture

When evaluating cybersecurity solution providers, security professionals prioritize expertise and proven methodologies. TwinTech solutions positions itself as a leader in achieving PCI DSS compliance for organizations. Their focus on a holistic approach goes beyond just implementing individual controls. They likely possess a well-defined methodology for guiding clients through the entire PCI DSS compliance journey, ensuring all necessary aspects are addressed. While client trust and a general focus on best practices are positive attributes, highlighting specific strengths like proven success rates with PCI DSS implementations or mentioning complementary services offered (penetration testing, vulnerability assessments) would provide a more compelling case for security professionals.

Our Expertise

TwinTech Solutions’ strength lies in its team of certified cybersecurity compliance experts. These experts aren’t just certified – they have practical experience with leading Security Information and Event Management (SIEM) tools, network monitoring solutions, and Data Loss Prevention (DLP) technologies. This goes beyond theoretical knowledge; they understand how to implement these tools effectively in real-world scenarios. Furthermore, TwinTech Solutin’s team boasts a broad industry background, having collaborated with organizations across various sectors. This translates to deep expertise in navigating not just standard compliances but also industry-specific requirements and regulations. Their team includes both compliance implementers and Qualified Security Assessors (QSAs) who possess a comprehensive understanding of international IT frameworks and compliance acts. This combination of technical skills and compliance knowledge allows TwinTech solution to deliver optimized solutions tailored to each client’s unique needs and industry.

Our Approach

Risk Assessment

TwinTech solutions gap & scope assessment meticulously identifies all cardholder data (CHD) flows through network mapping, code review, and interviews. This data is then mapped against PCI DSS controls to pinpoint gaps and define a focused, comprehensive assessment scope

1. Identify all processes interacting with cardholder data (CHD), including 16-digit PAN
2. Initiate meetings with relevant process owners.
3. Conduct policy review and gap analysis against all 12 PCI DSS requirements
4. Initiate discussions with IT to understand network and application architecture
5. Perform process audits to assess IT & security control effectiveness.
6. Develop and deliver gap report outlining compliance deficiencies to stakeholders.
7. Create prioritized remediation plan based on risk and PCI DSS implementation approach.

Gap Remediation and PCI DSS Compliance

Following the completion of the Gap Assessment phase, a dedicated team of technical and process experts will offer remediation support. Additionally, we will aid in the development of essential information and cybersecurity policies and procedures. Risk assessment activities will commence after initial training, with recommendations documented for closing identified gaps. Key teams will be assigned responsibilities accordingly. This support includes two aspects:

PCI Scope Reduction/Segmentation Support


Provide recommendations for reducing PCI scope

Assist in finalizing implementation controls to reduce the PCI DSS scope

Non-Technical Implementation Support


Review and develop necessary PCI DSS policies, processes, and procedures.

Conduct awareness sessions for IT/Security teams and relevant business users within
the PCI DSS scope

Offer assistance in establishing stable and secure processes to achieve PCI DSS
compliance across customers

Support in risk assessment and mitigation planning

PCI Shield Service

During this phase, we support our customers by assisting them with several PCI DSSrelated tasks, including:


Maintaining PCI DSS Compliance

Maintaining Information Security Policy and Procedure Reviews

Training and Awareness

PCI QSA Assessment

During an official PCI DSS audit and certification (RoC), a Qualified Security Assessor (QSA) thoroughly examines the customer’s information security controls against each section of the PCI DSS Report on Compliance.
As part of the audit, the QSA meticulously details their actions and observations related to each clause of the PCI DSS. This information is included in the RoC, which is constructed in accordance with the PCI SSC’s RoC reporting instructions.Upon completion of the audit, the customer receives comprehensive audit documentation, including the official RoC, outlining the findings and compliance status.

What is PCI DSS Controls?

What is PA-DSS in PCI DSS?

What is the role of ASV in network testing?

ASVs (Approved Scanning Vendors) are security firms that validate external PCI DSS compliance using scanning tools. Level 1 organizations require quarterly PCI network scans conducted by an ASV to ensure ongoing vulnerability management

Can anyone become an Internal Security Assessor?

PCI DSS training empowers organizations to build internal security expertise. However, for full compliance, a Qualified Security Assessor (QSA) is required. QSAs work collaboratively with on-site security professionals (ISAs) to achieve end-to-end PCI DSS validation.

Is TwinTech an ASV ?

No currently is not a PCI dss ASV qsa avaiable
