Secure Connected Devices with IoT Device Penetration Testing
Enabling security teams to nearly eliminate critical and high findings within the first six months.
IoT devices expand your attack surface beyond traditional infrastructure. Our IoT penetration testing validates real-world exploitability across firmware, network exposure, authentication mechanisms, and embedded systems, so your team can prioritize and remediate what truly increases risk.
Validate Device Exploitability
We simulate attacker techniques against firmware, embedded systems, APIs, and communication protocols to confirm which weaknesses can actually be abused.
Prevent Lateral Movement
Identify how compromised IoT devices could be leveraged to access internal networks, sensitive systems, or cloud environments.
Reduce Exposure Across Connected Environments
Deliver validated findings with remediation clarity so engineering and infrastructure teams can break attack paths and reduce measurable risk.
IoT Security That Validates Real-World Exploitability, Not Just Surface Findings
IoT devices introduce embedded systems, firmware, APIs, and communication protocols that often operate outside traditional security controls. A vulnerable device isn’t just a device risk; it can become a foothold into your broader network.
Our IoT penetration testing simulates real attacker behavior against connected devices and their supporting infrastructure to confirm which weaknesses are actually exploitable and how they could be leveraged to impact your environment.
Confirm Whether Firmware Weaknesses Can Actually Be Exploited
We perform hands-on analysis of firmware images, bootloaders, authentication logic, update mechanisms, and embedded services to determine whether vulnerabilities can be leveraged for device compromise. This includes identifying hardcoded credentials, insecure storage, privilege escalation paths, and exposed debug interfaces.
Rather than listing theoretical issues, we validate which weaknesses allow control, persistence, or data extraction, so engineering teams focus on eliminating true device-level risk.
Validate How Devices Communicate, and Where That Communication Breaks Down
IoT devices rely on APIs, cloud integrations, wireless protocols, and backend services to function. We test communication channels, including MQTT, HTTP/S, Bluetooth, Zigbee, proprietary protocols, and device-to-cloud pathways to determine whether traffic can be intercepted, manipulated, replayed, or abused.
This confirms whether attackers can exploit insecure transmission, weak authentication, or misconfigurations to gain unauthorized access or tamper with device behavior.
Identify How a Compromised Device Could Be Used to Access Core Systems
A single vulnerable IoT device can become an entry point into internal networks. We simulate lateral movement and privilege escalation scenarios to determine whether device compromise could lead to broader access into infrastructure, applications, or sensitive data systems.
By mapping realistic attack chains, we help you prioritize fixes that break pivot paths and reduce the blast radius of device-level exposure.
Deliver Clear Fix Paths and Re-Test to Confirm Risk Reduction
Validated findings are delivered with technical detail, reproduction steps, exploit evidence, and remediation clarity tailored to firmware and engineering teams. We don’t stop at identification; we help ensure fixes address root causes.
Through structured re-testing and continuous validation, you gain measurable visibility into exposure reduction across your IoT ecosystem rather than relying on one-time assessment results.
TrollEye Security Recognized as a Sample Vendor in Gartner’s 2025 Hype Cycle for Security Operations
IoT Device Penetration Testing Focused on Mobilization
Connected devices don’t stay static. Firmware updates, new integrations, configuration changes, and expanded deployments continuously reshape risk. That’s why our IoT testing isn’t delivered as a one-time report; it operates as part of a structured, continuous PTaaS solution.
Each engagement follows a repeatable cycle designed to validate real-world exploitability and mobilize remediation across firmware, infrastructure, and supporting systems.
Establish Real Visibility Across Your IoT Attack Surface
We begin by identifying device models, firmware versions, exposed services, backend integrations, and communication pathways. This includes mapping how devices connect to internal networks, cloud platforms, APIs, and third-party systems.
Manual testing is combined with firmware analysis, embedded system inspection, and network reconnaissance to simulate how an attacker would realistically approach your connected environment.
Validate Exploitability and Map Device-Level Attack Paths
Findings are contextualized based on device function, network placement, and operational dependency. We assess how weaknesses in firmware, communication protocols, or authentication mechanisms could introduce broader infrastructure or business risk.
Rather than ranking issues by technical severity alone, vulnerabilities are prioritized based on their potential to disrupt operations, expose connected systems, or create persistent footholds.
Mobilize Remediation Across Firmware, Engineering, and Infrastructure Teams
Validated findings are delivered with exploit evidence, reproduction steps, and remediation clarity tailored to firmware engineers, DevOps teams, and infrastructure owners.
Role-based task distribution ensures the right teams receive the right findings with the right level of context. This reduces friction, accelerates fixes, and prevents device-level risk from stalling in backlogs.
Re-Test Devices to Confirm Risk Has Been Eliminated
Once remediation actions are implemented, we re-test affected firmware, configurations, and communication paths to confirm vulnerabilities have been fully resolved.
This step prevents recurring exposure, validates patch effectiveness, and ensures fixes do not introduce new weaknesses.
Strengthen IoT Security Posture Through Continuous Validation
Over time, recurring testing cycles improve firmware development practices, device hardening standards, segmentation strategies, and update processes.
As part of PTaaS, this continuous loop drives measurable reduction of device-level exposure, helps prevent IoT from becoming an entry point into core systems, and embeds security into how connected products are built and deployed.
Specialized Testing Across Every Domain with Penetration Testing as a Service (PTaaS)
IoT device penetration testing is only one component of an effective security program. While many providers treat it as a point-in-time exercise, our internal testing is delivered as part of Penetration Testing as a Service (PTaaS), providing continuous, attacker-driven validation across your internal environment.
On average, our clients see critical and high findings drop to almost zero within six months of starting PTaaS.

We Don't Just Test the Device, We Test the Ecosystem
IoT environments vary widely in architecture, communication protocols, and operational impact. Our testing approach adapts to the device’s function, connectivity model, and exposure surface, from embedded firmware to cloud APIs and mobile integrations.
Below are representative device categories we routinely assess.
Industrial Control Systems (ICS) & Operational Technology (OT)
PLCs, SCADA components, industrial sensors, and OT gateways. We identify insecure protocols, exposed interfaces, segmentation gaps, and firmware weaknesses that could enable disruption or lateral movement.
Smart Building & Facilities Devices
HVAC controllers, access systems, lighting platforms, and BMS environments. Testing focuses on authentication flaws, exposed services, and integration weaknesses that create pivot paths into corporate networks.
Healthcare & Medical IoT Devices
Connected medical equipment and remote monitoring systems. We assess wireless exposure, firmware integrity, and access controls that could impact data security or device functionality.
Consumer & Embedded Devices
Gateways, edge nodes, and device management platforms. We identify exposed services, weak encryption, and privilege escalation paths that could scale compromise across the ecosystem.
Network Infrastructure & Edge Devices
Gateways, edge nodes, and device management platforms. We identify exposed services, weak encryption, and privilege escalation paths that could scale compromise across the ecosystem.
Not Just the Device, the Ecosystem
We assess the full ecosystem surrounding connected technology, including firmware, update mechanisms, gateways, mobile applications, cloud APIs, identity controls, and network segmentation.
