Full PCI DSS v4.0 readiness — from gap assessment to QSA audit support. We handle the complexity so your payments infrastructure stays secure and certifiable, in the EU and US.
The Payment Card Industry Data Security Standard (PCI DSS) is a mandatory security framework required by all major card networks — Visa, Mastercard, Amex, Discover — for any business that stores, processes, or transmits cardholder data.
Version 4.0 introduced stricter requirements around authentication, encryption, and continuous monitoring. Non-compliance exposes you to fines up to $100,000/month, loss of payment processing rights, and reputational damage you can't undo.
Q-Sec makes PCI DSS achievable — not just a checkbox, but a real security baseline that protects your customers and your license to operate.
We map your environment against every control domain in PCI DSS v4.0, identify gaps, and build a remediation roadmap — then stay with you through the audit.
Q-Sec delivers a complete PCI DSS programme — from initial scoping through annual recertification. No consultant treadmill, no surprise fees.
We map your Cardholder Data Environment (CDE), identify every in-scope system, and produce a prioritised gap report against PCI DSS v4.0 requirements.
Our engineers implement controls directly — firewall rules, encryption configuration, access policy, log management — with full documentation for auditors.
24/7 SIEM coverage of your CDE. We alert on policy violations, configuration drift, and access anomalies — before your auditor does.
We prepare and manage your evidence pack, liaise directly with your Qualified Security Assessor, and handle findings triage throughout the ROC or SAQ process.
Internal and external penetration tests plus quarterly ASV vulnerability scanning — all in-house, faster to schedule, no third-party coordination delays.
Prebuilt, PCI DSS v4.0-aligned policies, procedures, and incident response templates. Ready to customise, ready to submit — not written from scratch.
We've engineered out the delays. Our onboarding takes ten business days. Certification timelines depend on your starting point — we'll tell you exactly where you stand on day one.
We map your CDE and define the audit scope. One call, clear output.
Engineers review your environment against all 12 requirement domains.
We implement controls, fix gaps, and document everything for auditors.
Evidence preparation, QSA liaison, and real-time findings response.
Continuous monitoring and annual recertification — we stay with you.
From lending platforms to payment gateways, Q-Sec secures the fintech companies that handle real money — with real accountability.
Client logos shown for illustrative reference. Specific services vary by engagement.
PCI DSS applies globally, but enforcement, overlapping regulations, and audit expectations differ significantly between the EU and US. We understand both.
European fintechs face compounding requirements — PCI DSS alongside DORA's digital operational resilience mandates and NIS2 cybersecurity obligations. Our compliance stack addresses all three in a single programme, reducing duplicated effort and documentation overhead.
US payment companies navigate PCI DSS alongside SOC 2 audit requirements, CCPA data privacy obligations, and state-level regulations like NYDFS Part 500. Q-Sec maps controls across frameworks so you don't certify the same environment twice.
Most PCI DSS consultants tell you what's wrong. We fix it. Our engineers sit inside your environment — not on the other end of a 90-day engagement letter.
Compliance support is a flat fee. 50 endpoints or 5,000 — the cost doesn't change. No retainer creep, no per-alert billing, no surprise invoices.
Setup takes about ten business days. Then we start monitoring. While others spend six months on deployment, you're already protected.
When you call, you reach our SOC in Warsaw — not a chatbot or an outsourced queue. Human analysts, verified escalations, minutes not hours.
Headquartered in Rotterdam. Your data stays in the EU. We follow the same regulations you do — GDPR, DORA, NIS2 — because we're subject to them too.
Incidents happen. The problem is not knowing about them. We make sure you do — fast, with context. No FUD. No vendor lock-in language.
SOC, MDR, Managed SIEM, and compliance consulting in one place. No stitching together vendors. No compliance tool that doesn't talk to your SOC.
Get a scoping call with a Q-Sec engineer. We'll tell you exactly where you stand, which SAQ or ROC applies, and what needs to happen — before you commit to anything.
