Testimonials
What our clients say
Each testimonial is tagged with the service we delivered: PCI PIN security assessments, card production audits, ISO 27001 consultancy, Cyber Essentials and penetration testing.
In my tenure as Principal Analyst for First National Bank of Omaha's Key Management and Cryptography program and many more years in the industry, I never realized how easy it could be to work with an assessor, nor the true value they could bring to a PIN security program until I began to work with Azie (Sovereign Secure, Ltd). Azie's knowledge and expertise is beyond reproach, and she truly stands out above and beyond in providing updates and changes in the compliance programs to her clients. Her passion and integrity are evidenced when she comes well prepared, is thorough and works efficiently, resulting in an accurate assessment.
The specialist team at Sovereign Secure provided valuable support throughout our EMV certification process. They demonstrated a keen understanding of PCI production requirements and expertly steered the audit to a successful conclusion. We commend them on their innovativeness in conducting the audit of our facility remotely and the proactive nature of their services. We want to make special mention of the Security Assessor, Agnes Ng for her professionalism, efficiency and undisputed industry knowledge. Agnes and her team at Sovereign Secure were a pleasure to work with and an excellent choice for anyone looking for security consultancy and assessment in the PCI Card Production Industry.

Approaching our PCI PIN 3.0 audit at the start of a pandemic was an overwhelming goal filled with uncertainties ranging from, “How could we ensure the safety of our employees & auditors?” to “Could this actually be done remotely?” Our colleagues at Sovereign Secure were true partners in this successful venture. While flexing to the distinct needs of an essential business, like ours, running during a pandemic, they stayed true to the high standards required of a business to ensure the PCI PIN 3.0 certification by the use of extraordinary communication, experienced auditors, and unique documentation delivery avenues. They made what was once thought of as impossible, not only very much possible, but also a pleasurable learning & partnership experience for our payment solutions team.

Sovereign Secure provided Payment Card Industry Compliance Services to Bamcard for the following standards: PCI CPSA, PCI DSS and PCI PIN. Even with the global COVID-19 pandemic, they managed to provide the best possible, knowledgeable support during the process of auditing and achieving compliance. The Sovereign Secure assessors were so helpful in these challenging times … with years of Payment Card Industry experience. We would happily recommend them to any company in need of the services mentioned.

I highly recommend services of Sovereign Secure through my work with Azie Amini; PCI PIN Security audits. I have known Azie for fifteen years and have nothing but positive things to say, regarding her PCI PIN services both in auditing and as a PIN security instructor. We have used her services for various payment companies that I have been employed by including Albertsons Companies.

We would like to thank Sovereign Secure on their guidance and assistance in obtaining ISO 27001:2017 for our company in both Singapore and Malaysia. Their security assessor went the extra mile to ensure that our processes were documented and that we were prepared for our external assessment. We are satisfied with the quality of work delivered by Sovereign Secure and would happily recommend them to any company that requires consultancy and guidance in obtaining their ISO 27001 certification.

Engaged Sovereign Secure for Penetration Testing and Cyber Essentials and received a professional and friendly service. The Cyber Security Services were delivered on time and price was competitive. I would highly recommend the team at Sovereign Secure … to any organisation.
