Deployment Architecture
Bringing Autonomous Reliability Into Secure Enclaves
Brain-outside, execution-inside architectures for regulated enterprises.

Why banks and regulated enterprises cannot use normal SaaS testing tools
Procurement teams ask where test data lives, who can access execution environments, and what leaves the network. Tools that require uploading production-like data to multi-tenant SaaS fail these reviews, even when the vendor is reputable.
Autonomous reliability amplifies the question: agents observe, decide, and act. Without boundary-aware design, autonomy becomes a liability.
The architecture principle: brain outside, execution inside
Intelligence and orchestration run in a control plane your security team can assess. Test and remediation execution run inside your enclave, private cloud, or on-prem footprint, where data never crosses an unapproved boundary.
Secure enclave pattern
Control plane (policy, graph, orchestration)
│ signed work packages only
▼
Customer enclave: Edge Runners + local evidence
│ sanitized egress
▼
Aggregated telemetry (no raw customer data)Signed test capsules
Work sent to enclave runners arrives as signed capsules: scoped commands, timeouts, allowed endpoints, and data classification labels. Runners reject unsigned or out-of-policy packages.
Local edge runners
Edge Runners execute capsules against internal URLs, desktop clients, and private APIs. They stream artifacts to local evidence stores, not to arbitrary vendor buckets.
Customer-controlled transfer boundary
Customers define what may egress: pass/fail summaries, redacted traces, hashes, or nothing at all. Transfer policies are enforceable and auditable.
Local evidence stores
Screenshots, HAR files, and logs remain in customer-controlled storage by default. Reviewers access evidence through existing security tooling.
Sanitized egress
When telemetry leaves the enclave, it is minimized and scrubbed. The goal is operational visibility without exfiltrating sensitive payloads.
PAM and secrets
Runners integrate with privileged access management and secret vaults, short-lived credentials, no long-lived keys in vendor SaaS. Secrets never appear in agent prompts or external logs.
Auditability
Audit questions your CISO will ask
- Who published each capsule
- What executed in which environment
- What evidence was produced and where it resides
- What egress occurred and under which policy
Deployment models
| Model | Best for | Tradeoff |
|---|---|---|
| SaaS control + enclave execution | Regulated hybrid | Requires runner ops |
| Private cloud control plane | Strict data residency | Higher infra ownership |
| Full on-prem | Air-gapped or sovereign | Longer rollout |
How to evaluate vendors
Ask for reference architectures, data-flow diagrams, and failure modes, not marketing claims. Validate runner isolation, capsule signing, egress policies, and evidence retention in your environment.
Final takeaway
Autonomous reliability can run in secure enclaves when architecture respects separation of intelligence and execution. Regulated buyers should demand this by default, not as a custom project.
