HIPAA Compliance, SLAs, and Enterprise Support for Wearable Health Infrastructure

Who This Is For

The CTO or VP Engineering at a regulated HealthTech company reads a lot of vendor pages that describe "enterprise support" as a premium tier with priority email. What they actually need to evaluate is specific: defined response times, data residency options, a security posture they can bring to their legal or compliance team, and clarity on what happens when something breaks at 11 PM on a Friday.

This article describes what Momentum's enterprise support covers for wearable health infrastructure. If you're in procurement, security review, or compliance evaluation, this is the detail that belongs in that conversation.

HIPAA Compliance in Wearable Infrastructure

HIPAA compliance for a wearable health platform is not a checklist you complete after the product is built. It's a set of architectural decisions that need to be made at deployment time. Retrofitting them is expensive and incomplete.

The relevant technical safeguards for a wearable data platform:

Data at rest. Health data stored in the platform database must be encrypted. AES-256 is the standard. This applies to the primary database, any read replicas, and database backups. Encryption key management must be documented, and key rotation must be operational, not theoretical.

Data in transit. All communication between mobile clients, the wearable platform API, and connected backend systems must use TLS 1.3. This includes the internal service-to-service communication within the platform infrastructure, not only the public-facing API.

Audit logging. Every access to patient health data must be logged with enough detail to reconstruct what data was accessed, by what system or user, and when. Audit logs must be tamper-resistant and retained according to your HIPAA retention requirements. This is the component that makes breach notification possible and meaningful.

Access controls. The principle of least privilege applied to every system component that touches health data. Service accounts with scoped permissions. No shared credentials. Multi-factor authentication on administrative access to infrastructure.

Minimum necessary standard. The data flowing from wearable devices to your platform should be scoped to what your product actually uses. Collecting all available health data from a provider API when your product uses three fields is a HIPAA exposure that's easy to avoid and rarely prioritized.

Business Associate Agreement. Momentum signs a BAA as part of enterprise engagements. This is a legal requirement for any covered entity or business associate that uses our services to process protected health information. The BAA specifies our obligations for safeguarding PHI, breach notification timelines, and permitted uses of the data.

Compliance for wearable platforms also requires downstream BAAs with the cloud provider hosting the infrastructure (AWS, GCP, or Azure all offer BAAs for HIPAA workloads) and any third-party services that process health data.

Incident Response SLAs

Enterprise support clients have a defined escalation path and committed response times.

P1: Critical

Definition: Platform API unavailable, data collection stopped for all users, or confirmed security incident involving PHI.

Response commitment: Acknowledgment within 1 hour, 24 hours a day, 7 days a week. Dedicated incident commander assigned. Status updates every 30 minutes until resolution. Root cause analysis delivered within 5 business days of resolution.

P2: High

Definition: Data collection degraded for a subset of providers, significant sync latency affecting product features, platform API returning elevated error rates.

Response commitment: Acknowledgment within 4 hours during business hours. Status updates every 2 hours until resolution.

P3: Medium/Low

Definition: Non-critical bugs, data quality anomalies, performance degradation below threshold, feature requests, documentation gaps.

Response commitment: Acknowledgment within 1 business day. Included in next scheduled maintenance window or sprint cycle depending on severity.

Escalation path for enterprise clients bypasses the standard support queue. You have a direct line to the engineer responsible for your infrastructure, not a ticketing system.

Custom Deployment Options

Standard deployments run on shared infrastructure in a cloud region you select. Enterprise clients with specific requirements have additional options.

Dedicated infrastructure. Your wearable platform runs on compute and storage resources not shared with other Momentum clients. Relevant for clients with data volume requirements that benefit from isolation, or compliance policies that prohibit multi-tenant infrastructure.

Private cloud / VPC deployment. The wearable platform deploys inside your own cloud account, in a VPC you control. Momentum manages the deployment and operations; your organization owns and controls the infrastructure. This is the architecture for clients where health data must never transit infrastructure outside their cloud boundary.

Air-gapped deployment. For environments where internet connectivity is restricted or prohibited, we support fully air-gapped deployment with manual update procedures. This is relevant for government health programs, military healthcare environments, or high-security clinical research facilities.

Regional requirements. Data residency selection is standard: US East, US West, EU (Frankfurt), and additional regions available on request. For clients with country-specific data residency requirements, we configure infrastructure to ensure health data does not leave the required jurisdiction.

Security Posture and Patch Cadence

Security patches. Critical security patches (CVE severity High or Critical) are applied within 72 hours of release for enterprise clients. Standard security updates follow a monthly deployment cycle with a staging validation window.

Vulnerability scanning. Infrastructure components are scanned continuously for known vulnerabilities. New findings are triaged within 24 hours and scheduled for remediation according to severity.

Penetration testing. Momentum conducts annual third-party penetration tests on platform infrastructure. Test results and remediation summaries are available to enterprise clients under NDA as part of security review processes. Clients with their own penetration testing requirements can schedule coordinated tests.

Dependency management. Application dependencies are monitored for security advisories. Updates are staged, tested, and deployed on a defined cycle. Dependencies with active exploits are treated as P1 issues.

Access review. Administrative access to production infrastructure is reviewed quarterly. Access that is no longer required is revoked. Service account permissions are reviewed on the same cycle.

Certification and Audit Documentation

Enterprise clients going through compliance certifications (HIPAA audit, SOC 2 readiness, ISO 27001) need documentation from their infrastructure vendors as part of the process. Momentum provides:

HIPAA documentation package: BAA, technical safeguard configuration documentation, encryption key management procedures, audit log retention policy, incident response procedures, and access control configuration.

SOC 2 readiness support: We can provide documentation of controls relevant to a SOC 2 Type II assessment for infrastructure Momentum manages. This includes availability (uptime data, SLA performance), confidentiality (encryption, access controls), and security (patch management, vulnerability response) controls.

Audit logs on demand: Comprehensive audit logs for your infrastructure, scoped to whatever period and detail level your audit requires, delivered in a format your auditors can work with.

Security questionnaire response: Enterprise procurement processes often include multi-page security questionnaires. We complete these for clients as part of the enterprise engagement. Most standard questionnaires turn around within 5 business days.

How Updates Work in Production

Platform updates for wearable infrastructure require a different process than a standard web application because sync failures during an update directly affect user data.

The update procedure for enterprise clients:

1. Update applied to a staging environment that mirrors the production configuration. Full regression testing including provider sync validation across all connected providers.
2. Release notes delivered to your technical contact at least 5 business days before production deployment. Includes what changed, what was tested, and any configuration changes required.
3. Production deployment scheduled during a defined maintenance window agreed with your team, or applied immediately for security patches.
4. Post-deployment sync validation: automated checks confirm that data collection rates, error rates, and sync latency return to baseline within 30 minutes of deployment. If they don't, automated rollback initiates.
5. Deployment summary delivered within 24 hours: what was deployed, validation results, and any anomalies observed.

Provider API updates (when Garmin, Oura, Whoop, or other providers change their APIs) follow the same process. We monitor provider developer channels, test the impact before it affects production, and deploy updates before the provider change would otherwise cause a silent failure.

Enterprise vs. Standard Support

The standard support service covers hosting, updates, incident response, and monitoring for teams that want reliable operations without a dedicated engagement. Most clients with stable products and internal DevOps capacity use this.

Enterprise support adds: defined SLAs with committed response times, dedicated escalation path to a named engineer, custom deployment options, HIPAA documentation packages, audit support, penetration test results access, and security questionnaire completion.

The right tier depends on your compliance requirements, your procurement process, and how much your product depends on health data availability. If a sync outage is a product inconvenience, standard support is the right fit. If a sync outage has clinical consequences or triggers a breach notification obligation, enterprise is the right conversation.

Starting the Enterprise Conversation

Enterprise engagements start with a discovery call covering your compliance requirements, data architecture, deployment constraints, and SLA needs. From that, we can confirm whether our standard enterprise package covers your requirements or whether custom terms are needed.
