IoT & Embedded Device Security Testing
We assess connected devices end to end — the hardware interfaces, extracted firmware, and the mobile app and cloud backend the device communicates with — to find flaws that live outside a typical web or mobile assessment.
- Extract and analyze firmware for hardcoded secrets and logic flaws
- Test hardware debug interfaces for unauthorized access
- Verify device-to-cloud communication and trust boundaries
Security context before security testing.
Connected devices carry risk across four layers — hardware, firmware, companion app and cloud backend — and a weakness in any one can undermine the others. Standard web or mobile assessments do not reach the hardware debug interfaces and firmware that are often the real point of compromise.
We work directly with physical device units: identifying and using hardware debug interfaces, extracting and statically analyzing firmware, and testing how the device, companion app and cloud backend trust and authenticate each other.
You are bringing a connected hardware product to market
The device handles sensitive data, access control or physical safety functions
Debug interfaces or update mechanisms have not been independently tested
Customers or partners require security validation before deployment at scale
What our specialists examine.
Coverage is adapted to your architecture and risk profile. These modules form the baseline for a complete iot & embedded device security testing.
Hardware interface discovery
Identifying UART, JTAG, SWD and other debug interfaces exposed on the device.
Firmware extraction and analysis
Extracting firmware from flash or update mechanisms and analyzing it for secrets and logic flaws.
Bootloader and update security
Testing whether firmware updates are authenticated, signed and protected from tampering.
Companion app assessment
Testing the mobile or desktop app that pairs with the device for trust and data-handling flaws.
Device-to-cloud communication
Verifying authentication, encryption and trust between the device and its cloud backend.
Local protocol and radio testing
Assessing Bluetooth, Zigbee, Wi-Fi or other local protocols the device uses for exploitable weaknesses.
What we need to begin efficiently.
Perfect documentation is not required. A clear starting point helps us confirm scope, reduce setup time and spend more of the engagement testing the risks that matter.
Assets and boundaries
A current list of the iot & embedded device security testing assets, environments and exclusions that should be covered.
Representative access
Physical device units, plus the roles, accounts or technical context needed to test realistic trust boundaries.
Operational contacts
A technical owner, emergency contact, approved testing window and any production constraints we should follow.
Architecture and priorities
Relevant diagrams, recent changes, high-value workflows and known concerns help us focus effort where failure matters most.
Share your architecture or business objective. We will help turn it into a practical assessment boundary and testing plan.
Start a scoping conversation →A controlled assessment with clear checkpoints.
You know what is being tested, what has been proven and what your team needs to do next throughout the engagement.
Device and interface reconnaissance
We identify hardware debug interfaces, firmware update paths and companion app/cloud touchpoints.
Firmware and hardware testing
We extract and analyze firmware and test debug interfaces for unauthorized access or secret exposure.
Backend and trust validation
We verify device-to-cloud authentication, companion app trust and data handling across the full device ecosystem.
Report, debrief and retest
We explain the attack paths, support remediation and verify submitted fixes with updated evidence.
Evidence your teams can actually use.
The output is designed for remediation, decision-making and assurance, not just for archiving after the test.
Device security assessment report
Findings across hardware, firmware, app and backend layers, with severity and reproduction evidence.
Firmware analysis summary
Extracted firmware findings including hardcoded secrets, debug artifacts and logic flaws.
Executive risk summary
A concise view of device risk relevant to product, safety and business stakeholders.
Remediation guidance
Practical fixes across hardware design, firmware, app and backend, prioritized by exploitability.
Retest and closure verification
Confirmation that remediated firmware, app or backend issues are resolved.
Bring us in when the decision carries real risk.
Validate a new connected product before shipping
Test hardware, firmware and backend security before units reach customers at scale.
Investigate a suspected device compromise
Assess whether firmware, debug interfaces or backend trust were exploited in a reported incident.
Provide independent security validation
Support partner, retailer or regulatory requirements for independent IoT security assessment.
One assessment. Clear outcomes for every team involved.
The same technical evidence is translated into the context each audience needs to make decisions, implement fixes and demonstrate assurance.
Reproduce and resolve findings faster.
Receive evidence, root-cause context and practical remediation guidance directly from the specialists who performed the work.
Prioritize risk with defensible context.
Understand exploitability, attack paths, systemic control gaps and the fixes that reduce the most meaningful exposure.
Use clear evidence for assurance decisions.
Get an executive view, standards mapping and verified closure status that can support governance, customer and audit conversations.
Security testing conducted with operational discipline.
A strong assessment must protect the systems and information it is intended to secure. These controls apply throughout the engagement.
Written authorization
Scope, permitted techniques, excluded assets and responsible contacts are agreed before any assessment activity begins.
Controlled execution
Testing follows defined windows, rate limits and production-safe rules with an immediate escalation and stop process.
Protected evidence
Engagement data and proof are access-controlled, handled confidentially and retained only for the agreed period.
Verified communication
Critical issues are escalated as soon as they are confirmed, with direct access to the specialist for remediation questions.
What teams ask before kickoff.
We finalize scope, access and safety controls before testing. These are the questions we answer most often for this service.
Do you need physical access to the device?
Can you test without hardware, using firmware only?
Do you cover the mobile app and cloud backend too?
Ready to make this assessment part of your security program?
We scope your environment, verify the risks, and hand you a remediation-ready report your team can act on.
