Global Expansion Recent office expansions and international collaborations (e.g., Amman, Jordan) indicate ongoing geographic growth and demand for cross-border risk, regulatory, and advisory services in emerging markets.

Security and Risk Reported data breach incidents and compliance settlements point to a strong sales case for cybersecurity, data protection, governance, risk, and compliance (GRC) transformations for clients in regulated industries.
