PCI DSS is the current enforced standard governing how any organization that stores, processes, or transmits cardholder data must operate. Across 12 requirements and six security goals, it sets the baseline for payment security globally. Bitsecura guides merchants and service providers through scoping, implementation, and formal attestation — so compliance is structured, defensible, and sustainable.
Whether you're a Level 1 merchant preparing for a QSA-led audit, a service provider managing cardholder data on behalf of clients, or a growing business determining your SAQ type for the first time, our phase-based approach takes you from obligation to compliance without disrupting operations.
Defining the boundaries of your Cardholder Data Environment (CDE) is the most consequential step in any PCI DSS programme. We trace every cardholder and sensitive authentication data flow, identify all in-scope systems and networks, and apply segmentation strategies to reduce your compliance footprint. A structured gap analysis against all 12 requirements then produces a prioritized remediation roadmap aligned to your merchant or service provider level — so your programme starts with clarity, not guesswork.
Once scope and gaps are defined, we build the controls, policies, and technical measures required to satisfy each applicable PCI DSS requirement. This covers access control frameworks, encryption and key management, vulnerability management cycles, logging and monitoring configurations, and the enhanced MFA and e-commerce controls introduced in the current standard. Every control is implemented alongside your teams — embedded in real workflows and validated against the standard, not filed away as documentation.
Formal PCI DSS compliance produces documented evidence that satisfies payment brands and acquiring banks. We prepare Level 1 merchants and service providers for QSA-led Reports on Compliance (ROC), coordinating evidence collection and managing the audit process from start to finish. For lower-level entities, we guide selection of the correct SAQ variant — A, B, C, D, or P2PE-HW — and ensure every response is accurate and defensible. The outcome is a clean Attestation of Compliance (AOC) your acquirer can act on.
Maintaining a valid Attestation of Compliance demonstrates to payment brands, acquiring banks, and customers that cardholder data is handled with rigour. Bitsecura combines deep PCI DSS expertise with practical security consulting to get you compliant — and keep you there through every annual assessment cycle.
Schedule a CallNo generic checklists. Every engagement is shaped by your merchant level, payment channels, and existing security maturity — not a one-size-fits-all template.
We map every cardholder data flow, identify all systems that store, process, or transmit CHD or SAD, and determine where segmentation can legitimately shrink your CDE. We also confirm your merchant or service provider level and the assessment type — ROC or SAQ — that applies. Scoping correctly is what determines how much compliance work you actually need to do.
A structured gap analysis against all 12 PCI DSS v4.0.1 requirements, evaluated against your specific environment and level. Findings are ranked by regulatory severity and remediation effort, giving your team a precise picture of where you stand before any implementation begins. No requirement is glossed over — especially the enhanced authentication, targeted risk analysis, and e-commerce controls now required.
Policies, technical controls, and governance structures are built to close identified gaps — encryption and key management, MFA enforcement, network segmentation validation, vulnerability management cycles, and security awareness programmes. Controls are implemented alongside your teams and validated against the standard before evidence is compiled. Compliance built into your environment, not bolted on after the fact.
We prepare your evidence package, coordinate with your QSA for ROC-assessed entities, and guide SAQ completion for applicable merchant levels. The outcome is a valid Attestation of Compliance that satisfies your acquiring bank, payment brands, and any contractual compliance obligations. You leave with a defensible AOC — and the controls in place to maintain it through the next assessment cycle.
