Security Architecture

Security is not a layer
we add on.
It is the layer we are.

Every action governed. Every connection controlled. Every decision auditable. Security inside Chameleon is not a compliance exercise, it is the architectural foundation that makes regulated AI deployment possible.

Security Posture

Designed for the most demanding regulated environments on earth.

Regulated financial services institutions face a security standard that is unlike almost any other industry. Every AI action must be authorisable. Every system interaction must be auditable. Every data access must be governed.

Chameleon is built for that standard, not retrofitted to meet it. Security is not a feature set. It is the execution layer itself.

Zero Trust

No implicit trust at any connection point

Every request authenticated, every connection authorised, every action validated, regardless of origin. Internal services are treated with the same scrutiny as external ones.

Least Privilege

Access is explicit, minimal, and role-scoped

Every agent, every user, every service receives only the access required for its specific function. Access does not inherit upward. It is granted explicitly and revoked precisely.

Audit by Default

Every action leaves a complete record

Audit trails are not generated retrospectively. They are created at the point of execution, before any action takes effect. Every decision, every data access, every AI output is recorded and attributable.

Encryption Everywhere

Data protected in transit and at rest

All data encrypted in transit using TLS 1.3. All data at rest encrypted using AES-256. Keys managed through AWS KMS with rotation policies enforced at platform level.

Security Architecture

Six layers of security between
the outside world and your data.

Security is enforced at every tier, from edge protection before a request reaches any service, to access governance inside the execution layer, to encryption at the storage tier.

01
Edge & Perimeter

Every request verified before it enters

All traffic routed through CloudFront CDN and AWS WAF with DDoS shield protection. No request reaches any application service without passing edge validation.

  • AWS WAF with custom rule sets
  • DDoS Shield Advanced
  • CloudFront CDN with geo-restriction
  • Route 53 with health-check failover
02
Identity & Access

Authentication at every interaction point

Cognito SSO and MFA enforced for all user access. API Gateway validates every inbound request. Service-to-service calls authenticated via IAM roles, never static credentials.

  • Cognito SSO with MFA enforcement
  • API Gateway with request validation
  • IAM role-based service authentication
  • Zero static credentials in any service
03
Network Isolation

Private infrastructure by default

All application workloads run inside a private VPC. Public subnets contain only load balancers. Application and data tiers are fully private. No open SSH ports at any tier.

  • Amazon VPC with private subnets
  • Multi-AZ across availability zones
  • Security groups with least-privilege rules
  • No direct internet access to application tier
04
Credential Governance

No exposed keys at any integration point

Chameleon connects to your enterprise systems without exposing credentials to the configuration layer. All keys managed through AWS Secrets Manager and KMS. Business users configure integrations without ever seeing credentials.

  • AWS Secrets Manager for all credentials
  • KMS key rotation enforced
  • No credentials in configuration layer
  • Role-based enterprise isolation
05
Observability & Detection

Continuous monitoring across every service

CloudWatch metrics and alerting across all components. CloudTrail captures every API call. X-Ray tracing provides end-to-end request visibility. Anomalous behaviour flagged in real time.

  • CloudWatch with custom dashboards and alerts
  • CloudTrail API audit across all services
  • X-Ray distributed tracing
  • Real-time anomaly detection
06
Resilience & Recovery

Engineered for zero-downtime operations

Multi-AZ active-active deployment with automated failover. ECS Fargate auto-scaling. RDS Multi-AZ with automated backup and point-in-time recovery. No single point of failure at any tier.

  • Multi-AZ active-active across all tiers
  • Automated failover with health checks
  • RDS point-in-time recovery
  • Zero-downtime deployment pipelines
Security inside Chameleon is not a layer we added when clients asked for it. It is the architecture we built first, because you cannot govern AI safely in regulated finance without it.
Deployment Options

Your environment.
Your sovereignty. Your choice.

Two deployment options. Same platform. Same security architecture. Same auditability. Different operating model. Whichever you choose, your regulators see the same controls.

Option 01

Managed SaaS on AWS

Enterprise-grade AWS infrastructure managed entirely by Chameleon. Multi-AZ, auto-scaling, zero operational overhead for your team. Security patches, platform upgrades, and infrastructure management handled without your involvement.

  • Multi-AZ deployment across AWS regions
  • Zero operational overhead for your team
  • Continuous security patching by Chameleon
  • SLA-backed uptime and performance
Option 02

Private Instance on Your AWS

Dedicated Chameleon instance deployed within your own AWS VPC. Your access controls. Your upgrade schedule. Your data never leaves your infrastructure perimeter. Full platform capability with complete internal sovereignty.

  • Deployed inside your own AWS VPC
  • Your access controls and IAM policies
  • Your upgrade approval and change management
  • Data never leaves your perimeter
AI Governance

Security that extends to
every AI action your platform takes.

Most security architectures were built before AI agents existed. Chameleon's governance layer was built with autonomous AI action as the core design constraint, because governing AI behaviour at scale requires capabilities that traditional security infrastructure does not have.

Authorisation

Every AI action explicitly authorised

No agent action executes without passing through the authorisation layer. Actions are validated against role permissions, data access policies, and business rules before execution. The agent does not decide what it is allowed to do, the platform does.

Traceability

Complete decision trace on every output

Every AI output includes a complete trace of the decision logic that produced it, which model, which data, which rules applied. Explainability is generated at the point of execution, not added after the fact.

Containment

Agent actions scoped and bounded

Every AI agent operates within explicit capability boundaries. Agents cannot exceed the permissions of the human role that configured them. Lateral movement between system contexts is blocked by design, not by policy enforcement alone.

Audit

Regulator-ready audit trail by default

Every AI interaction, prompt, reasoning step, tool call, output, and any downstream action, captured in an immutable audit trail. APRA and ASIC inquiries can be answered from platform-generated records without retrospective reconstruction.

The Security Guarantee

Security is not something
we sell separately.
It is what you get
by running Chameleon.

Every institution that deploys Chameleon inherits the same security architecture, the same edge protection, the same credential governance, the same AI action authorisation, the same regulator-ready audit trail. Security is not a tier. It is the platform.
