Cross-Stack Security Architecture

Security decisions at one layer ripple across the system. We design security that holds end-to-end.

Usable Security by Design

Security designed around real workflows, strong without friction for patients, clinicians, and end users.

Engineers Who Implement

The engineers who design your security architecture build and harden it.

Regulatory-Ready Cybersecurity

We support the secure framework and submission-ready evidence the FCC requires.

Security in connected systems

A Connected System Has No Single Security Perimeter.

Firmware, wireless protocols, mobile applications, and cloud backends each introduce a distinct attack surface. A decision made in one layer ripples through every other. Security that creates too much friction introduces its own risk: clinicians and end users route around it.

We design security across the full stack, from device hardware to backend systems, so controls hold together end-to-end.

The Result: A connected product where security is coherent across every layer, defensible under regulatory scrutiny, and built to hold up in the field.

Security Problems We Solve

Security Vulnerabilities That Surface Late & Cost More to Fix

Security addressed layer by layer, without a system-level security design, leaves vulnerabilities that surface late and compound across the stack.

System Security Architecture

Component-level security leaves trust boundaries undefined across a connected system.

Common Scenarios:

  • › Threat modeling absent from early design decisions
  • › Trust boundaries undefined across firmware, mobile, and cloud
  • › Security assumptions inconsistent between development teams
  • › Attack surface growing as system layers integrate
  • › Security review is happening too late to influence the architecture

Wireless & Protocol Security

Connected devices communicate via protocols with attack surfaces that require purpose-built security.

Common Scenarios:

  • › BLE pairing models that allow unauthenticated connections
  • › Control channels without session integrity or replay protection
  • › Protocol-level vulnerabilities exposing device to man-in-the-middle attacks
  • › Unencrypted data transmission across wireless links
  • › Weak authentication between device and mobile application

Device & Firmware Security

Vulnerabilities introduced at the firmware layer are the most difficult to remediate after deployment.

Common Scenarios:

  • › Firmware running without signature verification or chain of trust
  • › Cryptographic keys stored in accessible flash memory
  • › Debug interfaces left exposed in production builds
  • › No rollback protection on firmware update paths
  • › Hardware attestation is absent from the device identity model

Compliance-Ready Cybersecurity

Security built without regulatory requirements in mind creates rework when cybersecurity gaps surface late in development.

Common Scenarios:

  • › Threat model not tied to design history file
  • › Creating deliverables without a SPDF means FDA rejection
  • › Security risk management siloed from overall risk management process
  • › No documented PSIRT or post-market vulnerability response plan
  • › Security requirements not traced through design and verification

Provisioning & Identity Security

Provisioning flows that are brittle, spoofable, or undocumented create security gaps that scale with every device shipped.

Common Scenarios:

  • › Device identity not established or verifiable at manufacturing
  • › First-use pairing flows that can be spoofed or intercepted
  • › Credential issuance with no rotation or revocation strategy
  • › Provisioning process that breaks down at production scale
  • › Decommissioning flows are absent or incomplete

Security Across Disciplines

Security Applied at Every Layer of the Stack

Security isn't a parallel workstream. It's embedded in how we architect firmware, design mobile apps, build cloud systems, and design hardware.

Systems Architecture

Threat modeling, trust boundary definition, and attack surface analysis are applied at the system level before any layer begins implementation.

Our Process

Security Engineered Into Every Phase of Development

Security stays coherent across the stack when each phase builds on the decisions made before it. Here's how that looks in practice across a full engagement.

1. Discovery & Security Posture Review

We assess existing security posture, identify applicable regulatory requirements, and define the risks that matter before any security decisions are made.

2. Threat Model & Security Requirements

We translate identified risks into documented controls, with traceability from threat to requirement to design decision, that integrate with the design history file from the start.

3. Architecture & Design

We define trust boundaries, identities, data flows, and key and credential lifecycle across the full connected system. Security architecture decisions are made at the system level before implementation begins.

4. Implementation & Hardening

The engineers who designed the security architecture implement controls across hardware, firmware, mobile, and backend systems. Static analysis, secure coding review, and layer-by-layer hardening are part of implementation and not a separate gate at the end.

5. Verification, Validation & Evidence

We execute security verification, produce traceability matrices and audit evidence, and prepare the documentation package that supports regulatory submission. Findings that surface here loop back into architecture and implementation decisions.

6. Post-Market & Vulnerability Management

We establish monitoring posture, vulnerability triage processes, and coordinated disclosure practices so the device remains defensible after it ships.

What You Get

Built to Defend at Every Critical Moment

Security built into the development process puts you in a fundamentally different position at submission, launch, and beyond.

PCB electronics design documentation

Depending on your project scope, deliverables may include any of the following:

A Defensible Regulatory Submission
We build threat models, security risk management, and SBOM with traceability for a complete Design History File (DHF). Cybersecurity evidence exists when the product is developed, not assembled retroactively.
Security Coherent Across the Full Stack
We define trust boundaries at the architectural level and implement controls at each layer, with verification evidence produced at each phase. Every layer holds up under scrutiny because every layer was designed in the context of the others.
Post-Market Defensibility Built In
We establish SBOM, patch strategy, vulnerability intake, and PSIRT documentation during development. The product remains defensible as threats evolve, dependencies age, and post-market surveillance requirements grow.
Security Carried Through Implementation
The engineers who define the security model implement it across hardware, firmware, mobile, and backend systems. Design intent and execution stay aligned with no translation layer between security architecture and the controls that actually ship.
Security Designed Around Real Workflows
We build authentication flows, pairing models, and access controls around clinical and end-user behavior. Security that creates excessive friction introduces its own risk.
