Jezero AI
Move AI from experimentation to secure production in days, not months. Jezero AI combines CACI’s proven AWS cloud foundation with governed AI capabilities, helping organisations innovate without compromising security, compliance or control.
Everything you need to deploy AI securely
Most organisations adopting AI face a difficult choice: move quickly or remain secure. Jezero AI removes that compromise by combining governed AI capabilities with a secure, resilient AWS cloud foundation.
Purpose-built for government, defence, financial services and other regulated sectors, it supports secure deployment across regions and jurisdictions while helping organisations meet data residency and sovereignty requirements.
Every request is authenticated, every action is traceable and every integration is permissioned. This enables teams to move generative and agentic AI from experimentation to production with the auditability, control and assurance their environments demand.
A proven foundation
Secure by design, ready in under 24 hours
Before Jezero became an AI platform, it was a secure AWS cloud platform. Built on more than a decade of experience delivering large-scale UK Government platforms, that proven foundation is what makes the AI layer trustworthy.
Security built in from day one
Zero-trust principles, preventative and detective guardrails, automated account vending and continuous visibility are embedded into the platform.
Well-architected foundations
Built on the AWS Well-Architected Framework using infrastructure as code and self-service models for platform tenants.
Modular and scalable by design
Choose the components and tooling you need without starting again or compromising the security posture of other tenants.
Deployable in under 24 hours
Establish a secure AWS platform for AI in hours rather than spending months engineering the foundation.
Multi-region resilience
Support global, sovereign deployments with multi-region availability in excess of 99.9%.
Licence-free accelerator
Adopt Jezero without ongoing licence fees, hidden catches or long contractual tie-ins.
The Jezero AI layer
One governed platform from model to action
Jezero AI adds governed AI capability directly to the secure Jezero foundation. Every team building on it inherits enterprise-grade security, compliance and operational controls without having to engineer them independently.
Secure landing zone
A compliant AWS environment inherited from Jezero’s proven core platform.
Identity and access
Role-based permissions and policy enforcement across every layer.
LLM Gateway
Controlled access to approved foundation models, with every request authenticated, checked, logged and routed.
Platform MCP Server
Define which tools and systems agents can access, the actions they can take and the permissions they operate under.
Secure data pipeline
Classify, govern and control data before AI interaction while maintaining permissions and lineage.
Audit and observability
Log prompts, outputs, integrations and agent actions for complete operational visibility.
Compliance controls
Support alignment with recognised cloud, security, privacy and AI risk frameworks.
Cost management
Gain usage visibility and apply spend controls from day one.
Your AI applications
Build agents, RAG applications and custom workflows on a trusted foundation designed to support what comes next.
Empower developers
Enable innovation without shadow AI
When governed access is unavailable, teams may turn to public AI services, personal accounts or unapproved plugins. This shadow AI bypasses organisational security, compliance and audit controls, increasing the risk of data exposure, lost traceability and inconsistent model behaviour.
Approved model access
Give developers controlled access to approved foundation models through the LLM Gateway.
Secure IDE integrations
Support development tools such as Claude Code and Kiro within a governed environment.
Policy-based routing
Route requests according to organisational policy, model approval and workload requirements.
Data filtering
Apply controls before sensitive information can reach a model or external service.
Prompt and output logging
Retain the evidence needed for audit, investigation and continuous improvement.
Separated environments
Maintain clear boundaries across development, test and production environments.
Financial governance
Keep AI spend visible and under control
AI governance applies to finance as much as security. Jezero AI helps organisations monitor consumption, control budgets and optimise model selection before uncontrolled usage becomes embedded at scale.
Real-time spend visibility
Understand AI usage, model consumption and cost exposure across regions, departments and environments.
Budget limits and approvals
Set configurable budgets and approval workflows around model access and usage.
Automated thresholds
Trigger controls when consumption reaches defined organisational limits.
Usage anomaly detection
Identify abnormal, inefficient or high-risk activity through continuous monitoring.
Intelligent model routing
Direct workloads to the most cost-effective approved model that meets performance and policy needs.
No ongoing licence fees
Build the business case without adding recurring Jezero licence costs.

FAQs
Answers to common questions about Jezero AI.
Jezero AI is a secure AWS cloud platform for deploying governed generative and agentic AI. It combines Jezero’s proven secure landing zone with identity and access controls, an LLM Gateway, a Platform MCP Server, governed data pipelines, audit and observability, compliance controls and cost management. This gives regulated organisations a ready-made foundation for moving AI from experimentation into production without building every security and governance component from scratch.
Jezero AI is designed for organisations that cannot compromise on security, compliance, sovereignty or auditability. This includes government, defence, national security, financial services, healthcare, legal and law-enforcement environments. Its modular architecture also allows organisations to tailor the platform to their tooling and deployment requirements while retaining common security guardrails and operational controls.
The Jezero secure AWS foundation can be deployed in under 24 hours. This allows organisations to establish the core environment for governed AI in days rather than spending months engineering landing zones, policies, controls and platform tooling from scratch. The time required to launch a specific AI application will still depend on its data, integration, assurance and use-case requirements.
Jezero AI applies security and governance across infrastructure, data, models and agent actions. It supports data classification and tagging, network segmentation, private endpoints, role-based access, policy enforcement and governed data pipelines. Requests pass through a controlled LLM Gateway, while prompts, outputs and agent actions can be logged to provide traceability and reduce the risk of sensitive information reaching unapproved services.
The LLM Gateway provides a controlled interface between users or applications and approved foundation models. Every request can be authenticated, policy-checked, logged and routed according to organisational requirements. This helps prevent unauthorised model use, reduce data leakage, maintain an audit trail and direct workloads towards an approved model that balances security, performance and cost.
The Platform MCP Server defines which tools, data sources and systems AI agents can access, which actions they can take and the permissions under which they operate. Combined with secure model routing, governed data pipelines and action logging, this allows organisations to use agentic workflows within controlled boundaries, with human oversight where required and a traceable record of activity.
Yes. Jezero AI gives developers governed access to approved models and secure IDE integrations, reducing the incentive to use personal accounts, public AI services or unapproved plugins. Policy-based routing, data filtering, prompt and output logging, and separation across development, test and production environments allow teams to experiment and build while organisational security, compliance and cost controls remain in place.
Jezero AI is designed to support recognised security, privacy, cloud and AI risk frameworks, including NCSC Cloud Security Principles, ISO 42001, NIST AI RMF, the EU AI Act, GDPR, the AWS Well-Architected Framework and CIS Benchmarks. Its controls include role-based access, policy enforcement, data classification, private endpoints and detailed logging of prompts, outputs, integrations and agent actions. Specific compliance obligations should be assessed against each organisation’s use case and operating environment.
The platform provides visibility into model usage and cost exposure across teams, regions and environments. Organisations can configure budget limits, approval workflows and usage thresholds, monitor anomalies and route workloads to cost-effective approved models that meet performance and policy requirements. Jezero is also a licence-free accelerator, so there are no ongoing Jezero licence fees to add to the business case.
Jezero-TSE is a highly assured variant of the Jezero platform for sensitive and classified workloads. Built with AWS Trusted Secure Enclaves, it adds enhanced network isolation, stricter access controls, automated compliance remediation and reference architectures for national security, defence and law enforcement. Jezero AI can be delivered on a Jezero-TSE foundation when an organisation requires this higher level of assurance.
