    Security Policy Audit for a Fintech Company
    Nov 20, 2025
    15 min
    For fintech companies, having a strong security system is critically important, as weak policies can lead to fines and failures during official inspections. To assess the real maturity level and improve process governance, the client approached Datami for a security policy audit.

    The company operates in the international financial technology market and provides digital banking and BaaS solutions for payment institutions, electronic money services, and fintech platforms.

    A business that handles personal and financial data must maintain robust security policies, as any deficiencies can lead to fines and compliance risks.

    Tasks and challenges
    The client approached Datami to assess key documents: Backup Policy, ISMS Policy, BCP/DRP, Cryptographic Policy, ICT Risk Management Framework, Security Monitoring and Logging Policy, and Governance and Control Overview.
     
    The fintech company also requested a compliance review of these security policies with international standards and regulatory requirements – ISO 27001, DORA, GDPR, and NBG.
    • Conduct an audit of security policies and assess their compliance with international standards
    • Provide reports with assessments and recommendations for improving maturity levels

    Main project stages

    The project work included three stages. After reviewing the documentation, the Datami team checked seven security policies for compliance with international standards.

    • Security policy review
      Analyzed the content of the documents, identified gaps, and checked compliance with four standards.
    • Reports with recommendations
      Prepared detailed conclusions and suggestions to increase process maturity and update each policy.
    • Policy updates
      Implemented the changes that strengthened the effectiveness, consistency, and manageability of the security system.

    Results and recommendations
    Results and recommendations

    At the start of the project, several elements of the company’s security policies were assessed at the Defined and Repeatable maturity levels. After implementing Datami’s recommendations, the maturity level increased to Managed / Optimized.

    The fintech company received the following improvements:

    • implementation of MTTD, MTTA, MTTR, SLA, and FPR metrics;
    • mandatory post-incident analyses in accordance with DORA and ISO;
    • alignment of policy elements with regulatory standards;
    • strengthened vendor requirements and cryptographic clauses in contracts;
    • regular crypto-audits of third-party providers.

    As a result, the client significantly improved its cybersecurity posture:

    • security policies were updated according to ISO/IEC 27001, GDPR, DORA, and NBG requirements;
    • critical gaps in the Information Security Management System (ISMS) were identified and remediated;
    • access control, privilege management, logging, and monitoring were enhanced.

    Datami also recommended tracking updates to DORA, NBG, and GDPR and documenting them in the policy change log.
