What is PCI-DSS, and what does it mean for you?
PCI-DSS (Payment Card Industry Data Security Standard) is the global security standard every organisation that handles card data must meet. Level 1 is the most comprehensive level of assessment.
Tahsildar complies with the latest and strictest security protocols set by the global payments ecosystem. The certificate is independent auditors’ confirmation that our infrastructure is proactively protected against today’s and tomorrow’s cyber threats.

Four key benefits
- 01Customer trust and reputation
Your customers want to know their card details are safe when they pay. Infrastructure built to international standards tells them “it’s safe to pay here” and protects your brand.
- 02Lower risk and KVKK compliance
Storing and processing card data carries serious legal responsibility. We manage it all, from encryption to network security, so you can focus on growing your business.
- 03Business continuity
PCI-DSS v4.0.1 assesses not only data security but also a system’s resilience. Our architecture is hardened against cyber attacks to help keep your payments running 24/7.
- 04Audited to global standards
Our systems are regularly tested and validated by Qualified Security Assessors (QSA), keeping our infrastructure current, resilient and transparent.
Card details are protected from entry to the bank
The full 16-digit card number, expiry date and CVV are never stored in the clear on Tahsildar servers. Your panel only shows masked card details.
- 01Payment page on secure infrastructure
Even when the payment page appears on your website, it runs on our PCI-DSS infrastructure; card data never reaches your systems.
- 023D Secure verification
Card transactions are verified through the issuing bank’s 3D Secure step.
- 03End-to-end encryption
From the moment card data is entered until it reaches the bank, it travels through tunnels encrypted with 256-bit SSL.
- 04Masked records only
Transaction records keep only the first 6 and last 4 digits of the card; card data is transmitted encrypted via licensed payment infrastructure.
Security is at the core of our technology
Built under the Pionr umbrella, Tahsildar applies a “security first” principle to every line of code, from its microservice architecture to its encryption algorithms.
End-to-end encryptionData travels over encrypted channels; card data is never exposed at any step.
Proactive threat monitoringOur systems are monitored 24/7, so potential threats are detected and blocked early.
- Physical and digital access control
Strict protocols govern who can access data, when and how.
- Secure sessions and logs
Platform sign-ins can be protected with two-factor authentication, and sign-in and access logs are kept in line with regulations.
Redundant infrastructure, uninterrupted payments 24/7
B2B payments arrive at night, at weekends and at month-end. Our infrastructure is built to run without interruption, under the infrastructure and security controls PCI-DSS Level 1 requires.
The infrastructure controls PCI-DSS Level 1 requires, including microservice architecture, network security and protection against attacks, are applied across all our systems.
24/7 monitoring and alertingOur systems are monitored 24/7; if anything unusual happens, our team is alerted automatically.
