Executive Summary

Palisade is intended to become a shared guardrails platform for ADC AI applications, including current and future LibreAssist deployments. If Palisade sits in front of global AI application traffic, it will see or classify sensitive content such as PHI, PII, audio, images, prompts, model responses, safety signals, and policy violations. That makes privacy, data residency, retention, access control, and model-improvement governance first-class product requirements, not later operational details.

This document is an initial research brief and decision framework. It is not a final legal opinion. The goal is to help Product, Engineering, Legal, Privacy, Compliance, Cybersecurity, and Cloudflare account teams answer:

  • Where can Palisade run using Cloudflare regional controls?
  • Which Cloudflare products are suitable for PHI/PII paths in each region?
  • What data should Palisade store, avoid storing, quarantine, de-identify, or delete?
  • What retention policy should apply to raw objects, metadata, audit records, and model-improvement datasets?
  • What must be approved before Palisade supports regions outside the United States?

Initial posture:

  • Store the minimum data needed to operate, audit, debug, and improve guardrail quality.
  • Do not store raw non-compliant or unwanted content by default.
  • Use R2 for governed objects only when the data class, jurisdiction, retention period, and deletion behavior are approved.
  • Use D1 for metadata, file pointers, classification flags, retention status, audit state, and workflow status.
  • Treat embeddings, transcripts, redacted text, thumbnails, and de-identified records as sensitive derived data until Privacy/Legal confirms otherwise.
  • Do not use production PHI/PII for model training or fine-tuning unless Legal/Privacy approves the lawful basis, consent or authorization model, de-identification standard, data provenance, region, retention, and vendor terms.

Why This Matters for Palisade and LibreAssist

LibreAssist is currently U.S.-only, but the expected product direction is broader international availability. Palisade is also intended to serve multiple ADC AI applications, not just LibreAssist. A shared guardrail layer can improve safety and consistency, but it also centralizes sensitive inspection, verdicts, and operational evidence.

That centralization creates a governance challenge:

  • Guardrails may receive sensitive data even when the application does not intend to store it.
  • The most valuable examples for improving guardrails may be the highest-risk examples to retain.
  • The region where a request is inspected may differ from the region where logs, metadata, model providers, object storage, and dashboards operate.
  • Compliance requirements differ by geography, data type, patient/user relationship, product claims, and whether the AI system is used for care, wellness, support, or operational workflow.

Palisade should therefore define the data governance model before global rollout, not after the first regional expansion.

Research Approach

Use a source hierarchy:

  1. Primary product sources: Cloudflare docs, Cloudflare Trust Hub, Cloudflare account-team confirmation, executed Abbott agreements, and product-specific BAA/DPA language.
  2. Primary legal and regulator sources: HHS/OCR for HIPAA, European Commission and EDPB materials for GDPR and AI Act context, national regulators for country-specific privacy laws.
  3. Secondary legal indexes: IAPP Global Privacy Law and DPA Directory and DLA Piper Data Protection Laws of the World to identify relevant laws and regulators, then verify with official sources or Legal.
  4. Abbott internal sources: privacy classifications, cybersecurity standards, retention schedules, AI governance requirements, LibreAssist launch markets, and approved vendor lists.

This document deliberately separates likely engineering options from decisions that must be confirmed by Legal, Privacy, Compliance, Cybersecurity, or Cloudflare.

Global Cloudflare Readiness Map

Use this as the first working map for Palisade regional feasibility. It is not a country launch approval list.

Readiness tierRegions or marketsInitial Palisade stanceMain reason
Tier 1: first detailed reviewUnited States, EU/EEA, United KingdomGood candidates for first privacy architecture workStrong Cloudflare regional controls exist for U.S. and EU; LibreAssist starts in the U.S.; GDPR/UK GDPR needs early design input
Tier 2: likely follow-on reviewCanada, Japan, South Korea, Singapore, AustraliaEvaluate after U.S./EU model is definedCloudflare has Regional Services in these markets, but metadata boundary, PHI equivalent rules, and local health privacy requirements need confirmation
Tier 3: needs deeper legal and Cloudflare reviewBrazil/LATAM, India, Middle East, Turkey, UAE, Saudi Arabia, South AfricaDo not assume the U.S./EU design transfers directlyCloudflare Regional Services may be available in some countries, but local data localization, health data, AI rules, and storage options vary
Tier 4: special pathMainland ChinaTreat as separate product and compliance workstreamCloudflare China Network is a separate Enterprise subscription operated with JD Cloud, has product limitations, ICP/content-vetting requirements, and local regulatory considerations
Tier 5: restricted or blocked until approvedSanctioned countries and restricted territoriesDo not launch or process without Legal/Trade Compliance approvalOFAC and other sanctions programs may prohibit or restrict services, transfers, support, or business activity

Cloudflare Regional Controls and Product Fit

Cloudflare has several different location concepts. They are not interchangeable:

  • Regional Services controls where HTTPS traffic is decrypted and inspected.
  • Customer Metadata Boundary controls where Cloudflare traffic logs and analytics metadata are stored.
  • R2 and D1 jurisdiction settings control where those storage products persist data.
  • Location hints are performance hints, not legal residency guarantees.
  • Product compatibility varies; each Palisade component must be validated against Cloudflare's current DLS compatibility matrix and Abbott's contracts.
Product or controlPotential Palisade roleRegional/privacy fitOpen concern
Workers on a zoneRuntime for proxy/check API and policy executionRegional Services can constrain HTTPS decryption/inspection for zone-based Workers; use custom domains rather than workers.dev for regulated pathsConfirm account enablement, managed/custom regions, and whether all Palisade routes are zone-based
R2Store governed audio, images, transcripts, redacted artifacts, and evidence packagesJurisdictional Restrictions can guarantee object storage in supported jurisdictions such as eu and fedramp; lifecycle rules can delete or transition objectsLocation hints are not residency guarantees; bucket jurisdiction cannot be changed after creation; confirm BAA/DPA coverage for each data class
R2 lifecycle rulesEnforce object expirationUseful for default deletion of raw objects, temporary debug captures, and review queuesMust align with legal hold and bucket lock behavior
R2 bucket locksPrevent premature deletion when requiredUseful only when a minimum retention period is legally requiredBucket locks override lifecycle deletion; dangerous for unwanted/non-compliant data if misapplied
D1Store metadata, object keys, classification flags, retention state, review decisions, and audit statusD1 supports jurisdictions such as eu and fedramp; D1 encrypts data at rest and in transitLocation hints are not guarantees; read replication may create global read copies when enabled; avoid storing raw PHI/PII in D1 unless approved
Workers AIRun AI-based checks or embeddingsCloudflare says Workers AI customer content is not used to train Workers AI or improve services without explicit consentDo not assume region-constrained inference; validate Workers AI DLS compatibility, model licenses, BAA coverage, and PHI suitability
AI GatewayObserve, route, control, and protect AI-provider callsUseful for AI traffic governance and prompt-injection/data-leak controlsDLS compatibility has limitations; provider-specific BAA, data retention, logging, and regional routing must be approved before PHI use
VectorizeStore embeddings for retrieval or similarity searchUseful for non-PHI knowledge retrieval or synthetic/de-identified evaluation searchDLS compatibility limitations mean no production PHI/PII embeddings until Legal/Privacy approve architecture and residency
Logs, analytics, LogpushSecurity and operations telemetryCustomer Metadata Boundary can keep Cloudflare Customer Logs in EU or U.S.; Logpush can export to approved storagePrompt/response content should not be general telemetry; ensure redaction before export
Cloudflare Access and Zero TrustProtect dashboard, admin workflows, and reviewer toolsStrong fit for identity-aware least privilege, RBAC, and auditabilityConfirm admin access across regions, out-of-region log access settings, and Abbott SSO integration
WAF, Bot Management, API Shield, Rate LimitingProtect public Palisade endpointsMany app security products are compatible with DLS featuresValidate product-specific caveats before regulated rollout
China NetworkPerformance/security path for Mainland ChinaSeparate Enterprise service with JD Cloud-operated infrastructureNot all products are available; ICP, content vetting, local monitoring, and partner data handling need a dedicated review

Data Categories

Palisade needs a simple, explicit data taxonomy before implementation. The taxonomy should be represented in D1 metadata and applied consistently to text, audio, image, and multimodal files.

CategoryExamplesDefault handlingPossible storage
Operational metadataRequest ID, app ID, policy profile, verdict, module version, latency, region, timestampStore for audit and operations with no raw prompt/response contentD1 and telemetry, region-scoped where required
Allowed content needed for auditApproved transcript sample, redacted model response, guardrail evidenceStore only if there is a defined audit or quality purpose and approved retentionR2 with D1 pointer and retention flags
PHI/PII contentHealth data, identifiers, voice recordings, images, transcripts, patient contextMinimize, region-scope, encrypt, restrict access, and delete by policyR2 jurisdiction bucket only if approved; D1 stores pointer and flags
Unwanted or non-compliant contentContent that violates policy, unsafe advice, irrelevant side conversation, sensitive leakage, prompt-injection payloadsDo not store raw content by default; store minimal metadata needed to prove handlingD1 metadata only; optional short-lived quarantine if approved
Quarantined review contentA flagged audio/image/text case needing human reviewStore in a restricted bucket with short TTL and reviewer workflowR2 quarantine bucket plus D1 review status
De-identified dataHIPAA de-identified cases, GDPR-anonymized or strongly pseudonymized samples, synthetic examplesUse for evaluation or model improvement only after reviewR2 de-identified/evaluation bucket
Model-training candidateHigh-value failure case, edge case, remediation exampleNot eligible until consent/lawful basis, de-identification, vendor terms, and governance are approvedSeparate governed dataset, not production raw store
Security telemetryThreat events, WAF/API Shield hits, auth failuresStore for security operations without user content where possibleSIEM/Logpush destination approved by Cybersecurity

Proposed Storage and Retention Model

Palisade should separate raw object storage from metadata and governance decisions:

  • R2 stores files and larger artifacts only when retention is approved.
  • D1 stores references, data classification flags, lifecycle state, and review state.
  • Telemetry stores metrics and traces without prompt, response, audio, image, or transcript bodies.

Recommended R2 bucket pattern:

Bucket patternIntended contentDefault retention
palisade-raw-<jurisdiction>Approved raw content needed for audit or product workflowLegal/Privacy-defined only; no default indefinite retention
palisade-quarantine-<jurisdiction>Restricted flagged content awaiting reviewShort TTL, for example 24 to 72 hours, unless Legal approves longer
palisade-redacted-<jurisdiction>Redacted transcripts, redacted screenshots, evidence snippets30 to 90 days unless a stricter regional policy applies
palisade-deidentified-<jurisdiction>Approved de-identified or anonymized examplesLonger retention possible if governance approves
palisade-eval-syntheticSynthetic evaluation dataLonger retention acceptable if confirmed non-sensitive

Recommended D1 metadata fields:

FieldPurpose
record_idStable Palisade metadata identifier
app_idSource app, for example libreassist
region_policyRegion or jurisdiction selected for processing/storage
object_keyR2 object key when an object exists
modalitytext, audio, image, or multimodal
policy_profilePalisade policy profile applied
verdictallow, flag, remediate, or block
contains_phiBoolean or tri-state classification
contains_piiBoolean or tri-state classification
policy_noncompliantWhether the content violated policy
risk_levelLow, medium, high, or critical
retention_classno_store, quarantine_short, audit_metadata, regulated_audit, deidentified_reuse, or legal_hold
delete_afterAutomatic deletion timestamp
review_statusnone, pending, approved, rejected, or deleted
training_eligibleFalse by default; true only after governance approval
lawful_basis_refReference to approved legal basis or policy document, not free text
consent_refReference to consent or authorization record when required
hashIntegrity/deduplication hash when safe to compute and store
created_at, deleted_atLifecycle audit timestamps

Retention classes should be simple enough to implement:

Retention classDefault ruleNotes
no_storeNo raw object persistedDefault for unwanted/non-compliant content
quarantine_shortDelete quickly after review windowNeeds strict reviewer RBAC and audit trail
audit_metadataKeep metadata onlyUseful for evidence without retaining raw content
regulated_auditKeep only when required by approved policyMay need R2 bucket locks; avoid for unwanted content
deidentified_reuseKeep de-identified/synthetic cases for evaluationRequires documented de-identification method and re-identification risk review
legal_holdSuspend deletion under Legal controlMust override automated deletion intentionally and visibly

Model Improvement and Training Use Considerations

Palisade will generate useful examples for improving guardrails: false positives, false negatives, prompt-injection attempts, unsafe medical advice, irrelevant audio, side conversations, remediation failures, and region-specific edge cases. Those examples are valuable, but using them for training or fine-tuning can create high legal and privacy risk.

Recommended policy:

  • Production raw PHI/PII is not training data by default.
  • Non-compliant or unwanted raw content is not training data by default.
  • Training eligibility must be explicit in D1 metadata and false unless approved.
  • Model-improvement datasets should prefer synthetic, de-identified, or strongly redacted examples.
  • De-identification must be documented; for U.S. PHI, HHS recognizes Expert Determination and Safe Harbor methods.
  • EU/UK data must be reviewed under GDPR/UK GDPR concepts such as purpose limitation, data minimization, special-category processing, and international transfer safeguards.
  • Audio and images need special review because voice, face, device screenshots, and background context may identify people even after transcript redaction.
  • Embeddings should be treated as derived sensitive data; do not store PHI/PII embeddings in Vectorize until residency, deletion, and re-identification risk are approved.
  • Any third-party model provider or AI gateway used for training, evaluation, or inference must have approved contractual terms, retention settings, BAA/DPA where needed, and documented no-training/no-retention posture.
