What C4i Solutions does

C4i Solutions Pty Ltd is an Australian veteran-owned ICT, cyber security, digital solutions and advisory firm founded in 2017 by Benjamin Sherrin and headquartered in Jamisontown, New South Wales, with a second office in Canberra, Australian Capital Territory. The company operates with 11-50 employees and remains privately held without disclosed external funding.

The firm delivers five core service lines: Secure Mission Platforms, Technology Managed Solutions, Technology Integration & Development, Cyber Security & Information Assurance, and Technology Advisory. The technical approach combines platform delivery, managed services, custom integration work and advisory engagements, underpinned by an unusually deep certification stack that includes DISP membership, ASD membership, IRAP assessment, ISO 27001, ITAR compliance, and alignment with ISM, PSPF, DSPF, Essential Eight, NIST CSF, IEC 62443 and C2M2. Customers are drawn from Defence — Royal Australian Navy, Australian Army and Royal Australian Air Force — as well as federal and state government agencies, the space sector, emergency services and critical infrastructure operators. Strategic partnerships with Thales, BlueZone and QS Group extend reach into Defence prime and specialist SME ecosystems, and the company holds Veteran Employer of Choice recognition that reinforces its positioning in the cleared-talent segment of the Australian Defence ICT market.

C4i monetises through project-based and managed-services contracts typical of the Australian Defence and Government ICT procurement environment, with revenue derived from long-cycle engagements rather than transactional pricing. Its go-to-market is anchored on security-cleared personnel and sovereign-Australian credentials — DISP membership, veteran-owned status, ASD/IRAP accreditations — using a mix of direct contracting and prime/sub partnerships (notably with Thales). All disclosed revenue, contract values and unit economics remain private, so scale is inferred solely from headcount and the breadth of the certification and partnership footprint.

Expansion highlights4 records

Direct peers

• Leidos Australia: Operates a significant Australian Defence ICT, cyber, and systems integration practice delivering C4I, cyber security, and mission support across the ADF. Closest US-listed peer by service mix — also competes head-to-head against C4i for managed services and integration work packages.
• Saab Australia: Australian subsidiary of Saab AB delivering sovereign Defence ICT, combat systems integration, and C2 capability to the ADF — directly comparable to C4i's C2/mission platform offering and similar sovereign positioning.
• CEA Technologies: Australian-owned Defence technology firm delivering radar, C2, and integrated mission systems to the RAN and wider ADF. Comparable as a sovereign Australian mid-sized Defence tech integrator targeting similar Navy and joint-force programs.
• Fujitsu Australia: Major IT services provider to Australian Defence and Government including managed services, cyber, and systems integration. Overlaps with C4i's Technology Managed Solutions and Cyber Security & Information Assurance lines, particularly in classified Defence environments.
• DXC Technology Australia: Global IT services firm with a significant Australian Defence and Government practice delivering managed IT, cyber security, and systems integration. Competes directly for managed services and integration work in the same customer base as C4i.

Broad incumbents

• Thales Australia: Global Defence prime with substantial Australian operations covering C4I, cyber, and mission systems. Already a partner of C4i — functions as both collaborator and broader competitor in adjacent ADF programs.
• BAE Systems Australia: Tier-1 global Defence prime with significant Australian operations across maritime, aerospace, and ICT. Competes for prime contractor roles on the same ADF programs where C4i seeks work-package carve-outs.
• Raytheon Australia: Subsidiary of RTX delivering major ADF programs (e.g., AIR 6500, LAND 19) with deep C4ISR, cyber, and systems integration capabilities. A larger incumbent competing for the same Defence ICT and C2 budgets.

Emerging players

• Aurecon (Defence & National Security): Australian engineering and advisory firm with a growing Defence and national security practice delivering systems engineering, digital, and advisory services to ADF and federal agencies — overlapping with C4i's Technology Advisory capability.
