Mission software, built and operated alongside the people who use it.
RankSaga partners with defence customers, prime contractors, and the agencies that serve them. We design, deploy, and operate AI-enabled software inside the environments where the work actually happens, sovereign cloud, on-premise, and air-gapped, and we stay deployed for as long as the mission requires.
We are not a delivery vendor. We are forward-deployed engineers who integrate with your team, your data, and your operational tempo, and remain on hand to harden, observe, and iterate against feedback from the field.
WHAT WE DO
Software, in the environment where the mission lives.
RankSaga's defence practice exists for one reason: too much promising software dies in the gap between a slide deck and an operational environment. The constraints that actually shape mission systems, classification, residency, identity, sovereignty, latency, and the daily reality of operating without an internet path, are routinely treated as afterthoughts. Our engineers treat them as the starting point.
We build inside the target environment from week one. If the deployment is in the Australian sovereign Azure region, we architect for that region's controls. If the workload runs inside an air-gapped enclave, we ship offline update flows, hardened supply chains, and inference paths that never call out. If the customer requires PROTECTED-classification handling, that posture shows up in identity, logging, and key management on day one, not as a hardening sprint after a pilot.
We work alongside operators, not above them. Our engagement model is forward-deployed: a small, senior team that integrates with your platform group, your data owners, and the people who will actually use what we build. We ship working software fast, and then we stay deployed, patching under load, ingesting field feedback, and keeping the system aligned to the mission as the mission changes.
CAPABILITY LINES
Six pillars, one operating model.
01 / Capability
Mission Software Engineering
Custom software for the systems your operators actually use. Decision-support tools, agent consoles, briefing applications, and integration layers built against the constraints of the production environment.
02 / Capability
Defence-Grade AI Systems
Production AI applications built for sensitive workloads, retrieval-augmented generation, semantic search, document understanding, and decision-support models that you can audit, attribute, and review.
03 / Capability
Air-Gapped Deployment
We deploy and operate AI software inside disconnected enclaves. Offline model artefacts, vector indices, and inference paths, currently running in production for the Australian Armed Forces.
04 / Capability
Microsoft Azure (Sovereign)
Architected for Australian sovereign Azure regions, IRAP-aligned controls, and PROTECTED-classification workloads. Landing zones, AI services, identity, and compliance integration in the cloud you already trust.
05 / Capability
AWS & GovCloud
Multi-region deployments on commercial AWS and AWS GovCloud-equivalents for partner-nation customers. Bedrock, SageMaker, and custom inference inside VPCs that meet your boundary requirements.
06 / Capability
Google Cloud (Government)
Vertex AI, Gemini-class model integration, and Anthos hybrid topologies for customers running on GCP. Designed for residency, sovereignty, and the operational constraints of regulated workloads.
HOW WE OPERATE
Forward-deployed, end-to-end, embedded.
We do not throw software over a fence. RankSaga engineers integrate with your team, work in your environment, and stay deployed alongside the mission. The engagement model is consistent across every defence capability line, only the technical surface changes.
01 / Step
Embedded Discovery
We sit alongside the team that owns the data, the workflow, and the operational risk. In the first weeks we map systems of record, the people who use them, and the constraints, classification, residency, latency, sovereignty, the solution must live inside.
02 / Step
Build in the Real Environment
We build inside the target environment, not a sandbox. Cloud, on-premise, or air-gapped, software ships against production constraints from week one. Hardening, observability, and governance are designed in, not bolted on.
03 / Step
Operate Under Tempo
We stay deployed. RankSaga engineers run alongside operators, patch under load, ingest field feedback into the next release, and keep the system aligned with the mission as the mission changes, for as long as the work requires.
PROOF
Live in production. Not a pilot.
An AI application built by RankSaga is currently deployed inside an air-gapped environment for the Australian Armed Forces. We architected, shipped, and continue to operate the system as a subcontractor on the programme.

QUESTIONS
What customers and primes typically ask.
Are you a prime contractor or a subcontractor?+
Both are workable. RankSaga has shipped capability inside ADF programmes as a subcontractor to a prime, and we engage directly with agencies, integrators, and platform groups depending on the programme structure. Our value is the same in either posture, forward-deployed engineers who integrate with the team that owns the mission.
What classifications can you operate inside?+
We are most experienced operating up to PROTECTED in Australian environments, including air-gapped deployments. For higher classifications and for partner-nation environments, we work to the customer's accreditation pathway, including IRAP-aligned uplift, ASD Essential Eight maturity, and equivalent partner-nation controls.
Do you build the software, or do you only deploy it?+
Both. Most of our engagements involve writing the application, backends, inference services, operator-facing interfaces, integration layers, and then deploying and operating it inside the production environment. We are an engineering team first, not a managed-services vendor.
What does an engagement look like?+
Typically: a discovery sprint to map the environment, a small forward-deployed team building in the production target from week one, working software in operator hands within weeks rather than quarters, and ongoing embedded support for as long as the customer requires it.
Can you bring your own AI models, or do you use the customer's?+
Either, and frequently both. We work with sovereign-hosted foundation models, customer-provided models, and open-weight models we deploy and harden inside the customer environment. Model choice is driven by the workload, the residency posture, and the auditability requirements, not by vendor preference.
How do you handle ongoing security posture?+
Hardening, observability, and supply-chain integrity are built in from day one, not added in a separate phase. We design for IRAP-aligned controls in Australian environments and equivalent partner-nation frameworks elsewhere, with patch and update flows that work in air-gapped enclaves where required.
ENGAGE
Bring us in early. We are most useful when the problem is hard.
Our engagements start with a real conversation, not an RFP response. If you operate in a defence, government, or critical-infrastructure environment and have a mission-software problem worth solving, we want to hear about it.
ENGAGE
Bring us in on the problem before it has a name.
We work best when we are embedded early, alongside the team that owns the mission, the data, and the operational risk. Government, commercial enterprise, or defence: if your environment is regulated, sensitive, or air-gapped, that is where we are most useful.
