Regulatory Compliance and Remediation for a regional Bank

Client Profile and Challenge

Client: Our client, a regional financial institution operating across three U.S. states, holding significant customer data, and subject to stringent regulatory oversight by agencies such as the FDIC and OCC.

The Challenge

The Bank had a fragmented security posture, relying on various tools and uncoordinated processes. Their goals were to:

  • Meet Regulator Demands: Demonstrate adherence to the NIST Cybersecurity Framework (CSF), as recommended by U.S. regulators.

  • Achieve International Certification: Prepare for ISO/IEC 27001 certification to align with global best practices and strengthen international partnerships.

  • Identify and Close Gaps: Assess their current controls against NIST CSF and ISO 27001 requirements to identify deficiencies.

RiskCognition’s Approach and Methodology

RiskCognition applied a phased, integrated approach to streamline compliance with both frameworks efficiently.

Phase 1: Integrated Gap Analysis and Assessment

A specialized RiskCognition team conducted a unified assessment to identify overlaps and deficiencies across both standards.

Activity Description Deliverable
Cross-Referenced Control Mapping Mapped the Bank’s existing controls against NIST CSF (Identify, Protect, Detect, Respond, Recover) and ISO 27001:2022 Annex A controls (e.g., A.5 Organizational Controls, A.6 People Controls). Dual-Standard Gap Matrix — highlighting deficiencies across both frameworks.
Document Review Reviewed policies, procedures, and implementation evidence for critical domains such as access control, incident management, and business continuity. Evidence Traceability Report — identifying missing or insufficient documentation.
Stakeholder Interviews & Technical Testing Conducted interviews with IT, HR, Legal, and Operations teams, followed by validation of technical controls (e.g., configuration checks, penetration testing scope). Current State Assessment Report — quantifying maturity levels for each control area.

Key Finding:
The Bank demonstrated strength in Detect controls (per NIST CSF) due to a recent SIEM implementation but lacked formal ISMS documentation and governance processes required by ISO 27001 (e.g., context of the organization, risk treatment plan).

Phase 2: Remediation Strategy and Roadmap Development

Based on the findings, RiskCognition prioritized remediation efforts by risk severity, regulatory urgency, and implementation feasibility.

Strategic Priorities:

  • ISO 27001 Foundational ISMS: Establish key ISMS documents and governance (e.g., Information Security Policy, Statement of Applicability, Risk Acceptance Criteria).

  • NIST CSF High-Impact Controls: Remediate high-risk gaps in the Protect and Respond functions, including configuration management and incident response testing.

NIST CSF & ISO 27001 Alignment Remediation Action Implemented Outcome
A.8.1 (User End Point Devices) & PR.IP-12 (Configuration Management) Implemented a Mobile Device Management (MDM) solution and standardized security configurations for all endpoints. Reduced unmanaged endpoint risks and non-compliant configurations.
A.5.31 (Business Continuity) & RC.RP-1 (Response Planning) Developed and tested a full-scale Incident Response Playbook and integrated Disaster Recovery testing schedule. Improved incident containment time by 35% during simulations.
A.5.1 (Policies) & ID.AM-1 (Asset Inventory) Formalized ISMS scope and context, established a board-approved Information Security Policy, and implemented an automated IT Asset Management system. Achieved full ISO 27001 audit readiness and improved asset accountability under NIST CSF.
Outcome Summary:

  • Strengthened compliance posture aligned with both U.S. regulatory expectations and international standards.

  • Streamlined documentation and governance to support ongoing audit readiness.

  • Tangible risk reduction and measurable improvement in response times and control maturity.
