Organisational Chart — Current Structure (Authoritative)

Authoritative current organisational structure (2026). Suits ISYS6018 (security accountability & segregation of duties), ISYS2002 / ISAD5001 (stakeholder mapping), and ISYS6020 (executive decision authority). Reviewed 29-06-2026.

This is the current, authoritative org chart for CloudCore Networks. It reflects the post-2023 executive structure: a single CEO with five C-suite direct reports (CTO, CIO, CFO, CISO, COO) plus the CMO and Head of Compliance. The CISO reports directly to the CEO (independent of IT) with a dotted line to the board audit committee.

Reporting lines & accountability

Executive Reports to Direct remit
Dr Amina Chowdhury — CTO CEO Technology strategy & architecture; CSMP platform direction
Mark Gonzalez — CIO CEO IT operations, cloud infrastructure, internal platforms, engineering
Aisha Rahman — CFO CEO Finance, budgeting, financial risk & ROI
Sophia Martines — CISO CEO (dotted line to board audit committee) Security strategy, governance, risk & compliance oversight
Sarah Thompson — COO CEO Service delivery, customer support, HR, operational efficiency
Lisa Chen — CMO CEO Marketing & brand
Emily Chen — Head of Compliance CEO (partners with CISO) Regulatory compliance, internal & external audit liaison

Segregation-of-duties note for auditors. The CISO is independent of the CIO/CTO (direct CEO line), which is the intended control design. The Head of Compliance also reports to the CEO but operationally partners with the CISO — auditors should confirm this collaboration is documented, not assumed.

Currency: AUD. ~47 staff headcount (note: some internal sources cite a higher figure — this variance is a known documentation inconsistency). Document reviewed 29-06-2026.
