IoT Pen Testing

By certified & ex-developer pen-testers. Free re-testing & remediation support.

What is IoT Penetration Testing?

IoT Penetration Testing is a form of security testing that simulates real world attacks against IoT devices, networks, and applications to uncover security weaknesses before malicious actors can exploit them. The aim is to assess the overall security posture of your IoT infrastructure, including device firmware, APIs, cloud interfaces, mobile apps, and communication layers. Whether you're dealing with smart home technology, industrial IoT deployments, or medical equipment, testing helps organisations identify and mitigate security flaws that may lead to a data breach.

As the IoT market continues to expand, organisations deploying connected devices must ensure that their products and networks can withstand evolving cyber threats. At North IT, our testing focuses on everything from firmware vulnerabilities to insecure communication protocols, helping to strengthen your IoT security posture and reduce risk to your entire IoT ecosystem.

Common IoT Penetration Testing Vulnerabilities

Default Credentials

Many IoT devices ship with factory default or weak login credentials. These are often never changed, leaving a backdoor for attackers to gain unauthorised access with minimal effort.

Encryption

Inadequate or missing data-transit encryption is a major issue, particularly when communication protocols such as MQTT or CoAP are used without SSL/TLS. This leaves room for interception, tampering, or data theft during transmission.

Authentication

Weak or improperly implemented authentication mechanisms allow unauthorised users to gain access to privileged functions or data. This could include exposed APIs or insecure token handling in associated mobile apps or cloud platforms.

Security Controls

Insufficient security controls in device management interfaces or mobile companion apps make it easier for attackers to escalate privileges or tamper with settings. These vulnerabilities represent just a sample of what our team investigates during each engagement. By focusing on these issues early, we help our clients improve their overall security posture and minimise risk across their entire solution stack.

How does IoT Pen Testing work?

At North IT, we begin by defining the test steps presented for your specific solution, outlining what will be tested, how it will be tested, and the respective test cases to be used. This ensures transparency and alignment with your business and technical goals. Once the scope is confirmed, we dive into hands-on testing using a blend of automated tools and manual techniques. Testing includes everything from protocol analysis and API testing to device fuzzing and reverse engineering. The goal is to simulate real-world scenarios in which attackers might attempt to infiltrate your IoT infrastructure, exfiltrate sensitive data, or disable critical services. We prioritise a comprehensive methodology, ensuring that every layer of your IoT environments is assessed.

Identify Vulnerabilities and Address Them Effectively

Our approach identifies weaknesses across your devices, applications, networks, and cloud backends - offering solutions tailored to your stack and risk profile. Key areas we test include:
  • Insecure firmware and bootloaders (firmware vulnerabilities)
  • Insecure cloud APIs and mobile interfaces
  • Hardcoded or exposed credentials
  • Unauthenticated over-the-air (OTA) updates
  • Use of deprecated or weak communication protocols
  • Lack of device-level encryption
  • Vulnerable third-party libraries or components
  • Physical attack resistance
With these areas addressed, you're better positioned to reduce your exposure to threats, ensure compliance with industry standards, and defend against the types of attacks seen in the IoT field today.

Does IoT Penetration Testing Come with Free Re-Testing?

Yes. Many providers charge extra for follow-up testing, but at North IT, we believe re-testing should be part of the core service. Once you've implemented fixes, we'll re-test at no additional cost (within six weeks), helping you validate that all security flaws have been resolved.

Our re-testing phase mirrors the test cases and conditions of the original assessment. Updated reports include new test results, which you can share with auditors, customers, or other stakeholders to demonstrate your improved security posture.

Who conducts IOT Penetration Testing?

All our IoT penetration tests are performed by qualified cybersecurity experts with real-world experience in both offensive security and IoT systems development. We understand the underlying models and architecture that power today's connected devices, giving us a unique edge. Our testers follow industry best practices and regularly publish related work, contribute to vulnerability databases, and hold certifications such as OSCP, CREST CRT, and others. Many have a master's thesis or academic background in cyber security, making them adept at linking theory with practical outcomes.

Offering Complementary Guidance in Remediation

We believe finding vulnerabilities is only half the job. That's why we offer free, expert-led support to help your team fix the issues we discover.
This includes:
  • Explanation of how vulnerabilities were discovered
  • Code-level remediation advice
  • Best practices to avoid recurrence
  • Collaboration with development and QA teams
  • Guidance for integration into CI/CD pipelines
By equipping your team with the knowledge they need, we help you build more secure IoT devices and deploy IoT infrastructure that can withstand attack over the long term.
