We live in an era where everything is interconnected. From our smart watches to the home thermostat, including surveillance cameras, speakers, locks, and even the refrigerator. This interconnection, known as the Internet of Things (IoT), makes our lives easier in many ways.
Cybersecurity in IoT, is, today more than ever, a real need. The exponential growth in the number of connected devices has led to an increase in vulnerabilities and attacks.
It’s not just about protecting personal data; we’re also talking about physical security, privacy, business reputation, and even operational continuity in companies that rely on IoT for their processes.
Cybersecurity in IoT is not optional
According to a Kaspersky report, in the first half of 2023, there was a significant increase in threats targeting IoT devices, including DrDoS attacks, DDos, ransomware, and other types of malware that exploit common vulnerabilities such as default passwords and insecure network services.
And that’s just the tip of the iceberg. Many devices are not correctly configured, use weak passwords, or continue to run on outdated software.
One of the biggest mistakes is assuming that an IoT device is harmless because it does not store sensitive data. But it only needs to be connected to the same network as other, more critical equipment for it to become a gateway to the system.
What types of vulnerabilities are common in the IoT?
The threats affecting the IoT ecosystem are varied, but many share a familiar pattern: lack of basic protection.. Some examples:
- Default passwords.. Many IoT devices come with factory credentials that users never change.
- Unnecessary open ports.. Access that allows attackers to explore and manipulate the device easily.
- Non-existent or manual updates.. Many manufacturers do not offer automatic updates, leaving their devices vulnerable to known security flaws.
- Unencrypted communication.. Some devices transmit information in plain text, making it easier for third parties to intercept and read the data.
- Poor network segmentation.. Using the same network for IoT devices and personal computers or servers makes it easier for a breach to affect the entire system.
The importance of a global vision: IoT cybersecurity in companies
In the business environment, these vulnerabilities can have a devastating impact. Let’s consider a factory that automates processes using sensors, cameras, and interconnected equipment. A single compromised device can paralyze production or leak strategic information.
This is where having advanced surveillance and threat analysis tools, such as Kartos, Enthec’s business solution, is crucial.. Kartos enables you to identify vulnerabilities, such as leaked credentials on the dark web, exposed devices, or data leaks related to the company’s connected assets.
Kartos provides Continuous Threat Exposure Management (CTEM), offering a real-time, updated, and comprehensive view of the company’s exposure level.
Kartos not only detects but prioritizes the most relevant risks for the business and recommends concrete actions to mitigate each threat. This is especially useful for IT and cybersecurity managers, as it allows them to make quick and informed decisions.

IoT risks: beyond data
Security in IoT extends far beyond preventing information theft. Some of the IoT risks most relevant include:
- Unauthorized access to security cameras that can be used for spying or blackmail.
- Manipulation of sensors or automated systems, generating interruptions or physical damage.
- Using devices as bots in massive attacks (DDoS) without the user being aware.
What can we do? Strategies to improve cybersecurity in IoT
Basic measures that every user should adopt
- Change default passwords and use strong keys.
- Update the firmware of devices regularly.
- Disable unused features, such as remote administration.
- Separate the networks, creating an exclusive network for IoT devices.
- Review the permissions and access of each team.
Strategies for companies
- Inventory all IoT devices connected to the network.
- Implement cybersecurity solutions and cyber surveillance tools, such as Kartos, which identify exposed devices and leaks in real-time.
- Apply network segmentation policies to isolate vulnerable devices.
- Establish strong access controls and multi-factor authentication.
- Continuously monitor exposure to external threats, without relying solely on periodic audits.
And private users?
We cannot forget that homes are also increasingly complex IoT environments. For them, Enthec has developed Qondar, a customized CTEM solution for individuals.
Qondar enables anyone to verify if their credentials have been compromised, if their devices are publicly exposed, and even, beyond IoT technology, if there is any trace of their digital identity circulating in insecure environments. A handy tool for enhancing privacy and safeguarding against malicious uses of information and emerging technologies, such as IoT.
Prevention is cheaper than disaster
Investing in IoT cybersecurity is not an expense, but a wise investment.. The costs derived from a security breach (reputational damage, business interruptions, legal sanctions…) can far exceed any budget allocated to protection.
Additionally, being one step ahead in risk management allows companies to innovate with confidence, knowing that their digital environment is protected. And that translates into a competitive advantage.
Digital transformation is here to stay, and the Internet of Things (IoT) is a crucial component of this change. However, every new technology comes with its own set of risks. Shielding security in IoT should be a top priority for both companies and individuals.
Solutions like Kartos and Qondar by Enthec stand out in the way we manage those risks. It’s not just about protecting devices: it’s about protecting everything behind them.
