Lifecycle security for connected devices.
NeroTeam supports IoT teams from design to end-of-life. We validate security before launch, verify fixes after release, and provide clear, engineering-ready guidance throughout the vulnerability lifecycle.
Security across design, deployment, and long-term operations
We align device firmware, cloud APIs, and operational realities to reduce risk across the full IoT lifecycle.
Threat modeling & architecture review
Map data flows, trust boundaries, identity strategy, and update channels before code reaches production.
Firmware & application testing
Assess boot chains, storage, interfaces, companion apps, and cloud APIs with reproducible evidence.
Exposure management & response
Validate fixes, confirm mitigations, and support coordinated disclosure when needed.
Common exposure patterns we uncover
Our assessments focus on practical, device-aware fixes that reduce risk without disrupting production timelines.
- 01Weak or default credentials, insecure onboarding, and exposed maintenance interfaces.
- 02Firmware update weaknesses, including unsigned images and rollback gaps.
- 03Over-permissive cloud APIs, identity drift, and excessive telemetry collection.
- 04Supply chain and build pipeline gaps that reduce assurance.
Free device test pilot
We offer a limited number of introductory assessments each quarter to help teams validate their baseline security posture.
Capabilities aligned to device reality
Our work spans hardware, firmware, mobile applications, cloud services, and the operational layer.
Hardware & firmware analysis
Secure boot validation, debug interface review, storage inspection, and firmware diffing.
App & API assessment
Authentication, authorization, session management, and data access checks across interfaces.
Fleet risk management
Exposure monitoring, remediation validation, and long-term hardening guidance.
Hands-on research methods
We combine firmware extraction, binary reverse engineering, and device‑level interface analysis to identify practical attack paths.
Extraction & diffing
Filesystem analysis, version comparison, and update path review to spot regressions.
Ghidra-led analysis
Trace input handling, command execution paths, and authorization logic with rigor.
UART & debug interfaces
Review serial access, boot logs, and service exposure that can lead to privilege escalation.
How engagements run
We keep scope, timelines, and deliverables transparent so engineering teams can act quickly.
| Stage | What we do | What you get |
|---|---|---|
| Scoping | Asset inventory, threat model, and success criteria. | Clear plan and communication protocol. |
| Assessment | Hands-on device, firmware, and platform testing. | Prioritized findings with evidence. |
| Remediation | Fix guidance, validation, and regression checks. | Verified improvements and risk reduction. |
| Assurance | Long-term hardening and disclosure support. | Security roadmap and operational guidance. |
Responsible disclosure & confidentiality
Findings are shared privately with stakeholders and published only with mutual agreement.
- •Secure intake channels for sensitive evidence.
- •Clear timelines and escalation paths.
- •Support for public advisories when requested.
Research and proof of capability
We publish actionable research focused on real-world device exposures, privacy risks, and supply chain resilience.
Firmware update integrity
Assessment frameworks for secure boot chains, signed updates, and rollback protection.
Coordinated vulnerability handling
Vendor communication, remediation tracking, and advisory publication when fixes are available.
Post-patch assurance
Independent verification that remediations work at scale across device fleets.
