Cybersecurity & GRC Advisory Practice

Architecting governance that withstands supervisory scrutiny.

We advise boards, CISOs, Chief Risk Officers, and compliance leaders on structuring defensible Three-Lines-of-Defense operating models, rationalizing control registers, and transitioning from point-in-time spreadsheets to continuous assurance powered by OrviQ.

Enterprise GRC & Continuous Assurance Architecture

Transitioning from fragmented spreadsheets to governed systems of record

We help risk, compliance, and security leaders architect unified governance models across all three lines of defense—connecting statutory obligations, common control registers, RCSA waves, and OrviQ technology.

Advisory Focus Areas

Three Lines of Defense (1LOD / 2LOD / 3LOD) operating model & Segregation of Duties design
Control taxonomy rationalization (mapping one common control set across multiple regulations)
RCSA methodology design separating Design Adequacy from Operating Effectiveness
OrviQ platform onboarding, obligation decomposition, and evidence freshness rule calibration

Institutional Outcomes Delivered

  • Single governed chain from regulatory clause to validated control assurance
  • Elimination of manual spreadsheet trackers and unverified compliance assertions
  • Clear accountability across business unit owners, compliance challengers, and internal audit

Regulatory Compliance & Supervisory Readiness

Structured readiness for central bank, financial, and enterprise frameworks

Pragmatic gap analysis, Statement of Applicability (SoA) scoping, and supervisory examination preparation aligned with international control and resilience standards.

Advisory Focus Areas

Framework alignment: COSO Internal Control (2013), Basel Committee PSMOR, NIST CSF 2.0, ISO/IEC 27001, and ISO 31000
Regional and sector regulatory readiness (UK GDPR / DPA 2018, DORA, UAE NCAP, SBP expectations, PCI DSS)
Defensible Statement of Applicability (SoA) scoping and exclusion justification
Mock supervisory inspections and evidence submission bundle structuring

Institutional Outcomes Delivered

  • Clause-by-clause gap register with prioritized remediation roadmaps
  • Audit-ready evidence lineage capable of withstanding independent challenge
  • Structured supervisory inspection playbooks

Operational Resilience & Third-Party Risk Governance

Protecting critical business services and supply-chain dependencies

Advisory engineering to identify critical business services, define quantitative impact tolerances, map fourth-party concentration risks, and run severe-but-plausible disruption exercises.

Advisory Focus Areas

Critical Business Service identification and end-to-end dependency mapping (people, processes, tech, vendors)
Business Impact Analysis (BIA) and Maximum Tolerable Period of Disruption (MTPD) calibration
Third-Party Risk Management (TPRM) tiering frameworks and fourth-party concentration audits
Executive tabletop exercises simulating ransomware, cloud regional outages, and supplier defaults

Institutional Outcomes Delivered

  • Board-approved impact tolerance statements and dependency topology maps
  • Tiered vendor due-diligence workflows with automated certificate expiry gates
  • Documented scenario test results linked directly to risk mitigation actions

Executive Cybersecurity Strategy & vCISO Advisory

Technical governance for boards, risk committees, and technology leaders

Independent, vendor-neutral cybersecurity leadership bridging deep offensive/defensive engineering reality with board-level risk appetite, investment prioritization, and policy governance.

Advisory Focus Areas

Enterprise security policy library authoring, versioning, and annual review governance
Quantitative Key Risk Indicator (KRI) definition and board risk appetite band structuring
Security budget prioritization anchored to validated control gaps and threat exposure
Independent technical challenge of security architecture, M&A targets, and transformation programmes

Institutional Outcomes Delivered

  • Authoritative, non-boilerplate policy suite mapped to operational controls
  • Board reporting packs grounded in evaluated evidence rather than vanity metrics
  • Cohesive roadmap uniting offensive testing, defensive operations, and GRC assurance
OrviQAdvisory + Technology Execution

Don't leave advisory deliverables trapped in static slide decks.

Traditional consultancies hand over spreadsheets that go stale the day after an engagement ends. Nexa helps you operationalize your requirements, control register, Statement of Applicability, and risk workflows directly inside OrviQ.
