Outsourced CISO & Cybersecurity Leadership
GCG leads the development and oversight of enterprise-grade information security programs tailored to regulated and fast-scaling environments. Acting as your Outsourced Chief Information Security Officer (CISO), we oversee cyber risk management, internal controls, policy implementation, incident response, and communication with regulators and clients.
We’ve successfully guided clients through regulatory audits, incident investigations, and enterprise due diligence, ensuring cybersecurity readiness and defensibility at every level of the organization.
When credibility is critical, GCG delivers trusted cybersecurity leadership.
AI Governance, Risk & Compliance
Artificial Intelligence and machine learning technologies are transforming how firms operate — but also introducing new layers of risk. GCG supports organizations in building responsible and compliant AI programs that align with frameworks such as the NIST AI Risk Management Framework, ISO/IEC 42001, and the EU AI Act.
We advise on AI use policies, data governance, bias mitigation, and regulatory compliance for AI applications in finance, surveillance, onboarding, and analytics. Our goal: to help clients innovate responsibly, with safeguards in place.
Responsible AI starts with expert governance.
Cybersecurity & AI Due Diligence
GCG provides rigorous, independent cybersecurity and AI due diligence for mergers, acquisitions, and vendor evaluations. Our assessments identify key risks related to cybersecurity maturity, regulatory exposure, data protection practices, and AI governance.
We work with acquirers, targets, and investors to surface gaps early and recommend actionable remediation strategies — ensuring your deals are sound from a technology and compliance perspective.
We uncover hidden risks before they become liabilities.
Third-Party Risk & Institutional Readiness
Vendor onboarding has become a high-stakes process in regulated industries. GCG has supported vendors through thousands of onboarding reviews from banks, regulators, and enterprise clients.
