The 4 Most Common IoT Vulnerabilities (and How to Protect Your Business)

At Tuxdi, we love being part of the most important conversations in the technology world. That’s why we’re proud to share that our CEO, Fabricio Defelippe, was invited to participate in an article published by DesignRush, one of the most influential global platforms in design, innovation, and technology.

The article — “4 Biggest IoT Vulnerabilities Putting Your Business at Risk” — analyzes the most common threats faced by companies that rely on IoT devices in their operations. From Tuxdi, we contributed our perspective on how to address these risks through secure development, scalable infrastructure, and strategic planning.

Why is it important to talk about IoT?

The adoption of smart devices is growing at a rapid pace. From factory sensors and security cameras to connected home appliances, IoT is transforming entire industries. But this transformation also brings new challenges: more connected devices mean more entry points for cyberattacks.

If not properly managed, these devices can become critical vulnerabilities that compromise an entire company’s network. And that can be extremely costly.

The 4 main vulnerabilities highlighted in the article

1. Default configurations
   Many IoT devices are shipped with factory settings that are never changed during installation. The result? Weak passwords and open ports that are an open invitation to attackers.
2. Lack of firmware updates
   When manufacturers don’t release updates—or users fail to install them—devices remain exposed to known security flaws.
3. Weak authentication
   Poor credential management (such as reused passwords or systems without multi-factor authentication) leaves the door open to unauthorized access.
4. Unnecessary internet exposure
   Exposing devices directly to the public internet without proper security layers is like leaving a safe open in the middle of the street.

What does Tuxdi propose to address these challenges?

From our experience building robust and scalable platforms, we know the key is to prevent, automate, and monitor. For us, IoT devices should be treated as an integral part of a company’s digital ecosystem, not as an afterthought.

As Fabricio Defelippe explained in the article:

At Tuxdi, we work with our clients to:

• Design secure infrastructures from day one
• Integrate automated alerts and firmware update processes
• Apply strong authentication and data encryption
• Create continuous monitoring layers to anticipate potential threats
