Microsoft says Thunderbolt 3 is not safe for Surface products

Microsoft recently made a bold statement regarding the safety of Thunderbolt 3 for their Surface products, marking a significant departure from industry norms. This announcement has raised eyebrows and sparked a heated debate among tech enthusiasts and business professionals alike. With its aim to optimize search engine rankings, this article dives deep into the details of Microsoft's stance on Thunderbolt 3, providing valuable information for our target audience of business professionals between the ages of 25 and 65.

Firstly, let's address the question on everyone's mind: why does Microsoft consider Thunderbolt 3 unsafe for their Surface devices? The answer lies in the potential security risks it poses. Thunderbolt 3, developed by Intel, is a technology that enables lightning-fast data transfer speeds and video output through a single USB-C port. However, this convenience comes at a cost. The open nature of Thunderbolt 3 makes it vulnerable to malicious attacks, potentially compromising the security and integrity of the device.

Microsoft's primary concern revolves around the possibility of so-called "evil maid" attacks. This refers to a scenario where someone gains physical access to a laptop, such as a hotel maid cleaning a room, and inserts a malicious device into the Thunderbolt 3 port. This illicit hardware could then be used to compromise the device, steal sensitive data, or install malicious software without the user's knowledge. Microsoft is committed to ensuring the utmost security for their users, and this concern led them to take a stand against Thunderbolt 3.

While Thunderbolt 3 may not be present on Surface devices, Microsoft has not left its customers without alternative options. The company has developed a proprietary technology called Surface Connect, which provides a secure and versatile connection solution for Surface devices. Surface Connect offers a variety of functionalities, including data transfer, charging, and video output, with the added benefit of enhanced security measures.

It is worth noting that Thunderbolt 3's vulnerability to attacks is not a widespread or commonly exploited flaw. However, Microsoft's decision to prioritize security over convenience reflects their dedication to customer protection. By steering clear of Thunderbolt 3, Microsoft ensures that their Surface devices remain uncompromised and secure from potential threats.

In conclusion, Microsoft's recent statement regarding the omission of Thunderbolt 3 from their Surface products highlights the company's commitment to prioritizing security. While Thunderbolt 3 may offer lightning-fast data transfer speeds, its open nature makes it susceptible to malicious attacks, potentially compromising user data. In response, Microsoft has developed their own secure and versatile connection solution called Surface Connect, ensuring that their Surface devices offer both functionality and peace of mind. By staying true to their commitment to customer protection, Microsoft continues to set the standard for secure computing experiences.

How is its design?

The design of Microsoft's Surface products does not include support for Thunderbolt 3 technology, primarily due to safety concerns. While Thunderbolt 3 offers high data transfer speeds and multiple connectivity options, Microsoft has chosen to prioritize the security and stability of its devices.

One reason Microsoft has cited for not adopting Thunderbolt 3 is its potential vulnerability to direct memory access attacks. Such attacks can bypass the operating system's security controls and gain unauthorized access to a device's memory. By omitting Thunderbolt 3, Microsoft seeks to minimize these security risks and provide a safer user experience to its customers.

Additionally, Thunderbolt 3 uses a USB Type-C connector, which is physically similar to the Surface Connect port used by Microsoft. This similarity could lead to confusion and accidental use of incompatible devices or cables, potentially causing damage to both the Surface device and the connected peripheral.

While Thunderbolt 3 may offer advantages like faster data transfer and external display support, Microsoft has taken a cautious approach to ensure the security and reliability of its Surface products. By prioritizing these aspects, Microsoft aims to provide business professionals with a dependable and secure computing experience.

It's important to note that this decision is specific to Microsoft's Surface products and may not necessarily reflect the overall safety or suitability of Thunderbolt 3 for other devices. Each manufacturer assesses the trade-offs and decides on the design choices that align with their priorities and customer needs.

How is its performance?

Microsoft has stated that they consider Thunderbolt 3 to be potentially unsafe for Surface products. This decision may seem surprising to some, especially considering that Thunderbolt 3 is a widely used and highly regarded industry standard.

The primary concern raised by Microsoft is the potential security risks associated with Thunderbolt 3. While this technology allows for extremely fast data transfer speeds and the ability to connect multiple peripherals through a single port, it also presents the possibility of unauthorized access to a device.

One of the main issues with Thunderbolt 3 is its direct memory access (DMA) feature. DMA allows peripherals to access a computer's memory without requiring CPU intervention, which can significantly improve performance. However, this advantage also opens up the potential for attackers to gain unauthorized access to sensitive data.

To mitigate these risks, Microsoft has opted to use its proprietary Surface Connect technology instead of Thunderbolt 3 on their devices. Surface Connect provides similar functionality to Thunderbolt 3 but with enhanced security measures. By using Surface Connect, Microsoft aims to ensure the safety and integrity of their products, protecting users' sensitive information.

While it is understandable that some users may feel disappointed by Microsoft's decision to forego Thunderbolt 3, it is important to prioritize security. By using Surface Connect, Microsoft can better protect business professionals' data and provide a more secure environment for their devices.

It is worth noting that Thunderbolt 3 has not been completely abandoned in the industry, and many other manufacturers continue to embrace it. However, Microsoft's decision to prioritize security over performance in their Surface products shows their commitment to providing a safe and trustworthy experience for their target audience of business professionals.

What are the models?

Microsoft has stated that Thunderbolt 3 is not considered safe for Surface products. This applies specifically to models such as Surface Laptop 3, Surface Pro 7, and Surface Go 2, which do not have Thunderbolt 3 ports.

The reason behind this decision is primarily related to security concerns. Thunderbolt 3 technology allows for high-speed data transfer and connects various peripherals to a computer. However, it also presents a potential vulnerability, as it creates a direct memory access (DMA) pathway. This pathway could be exploited by malicious actors, jeopardizing the security of the device and its data.

Microsoft has a strong commitment to prioritizing the security and privacy of its users. By not including Thunderbolt 3 ports in their Surface products, they aim to reduce the risk of unauthorized access and protect sensitive information. While Thunderbolt 3 can offer convenience and versatility, Microsoft believes that the potential security risks outweigh these benefits.

It is important to note that Microsoft has not completely ruled out the possibility of adopting Thunderbolt 3 in the future. However, any decision to incorporate this technology will be made with careful consideration of security implications and ensuring the best experience for their users.

In summary, Microsoft has chosen not to include Thunderbolt 3 ports in certain Surface models due to security concerns. They prioritize the protection of user's data and aim to minimize potential vulnerabilities. While Thunderbolt 3 offers advantages, Microsoft believes that maintaining a high level of security is of utmost importance for their customers.


In conclusion, Microsoft has made it clear that they do not consider Thunderbolt 3 to be a safe option for their Surface products. While this may come as disappointing news to some users, it is important to understand the reasoning behind this decision.

One of the main concerns raised by Microsoft is the potential security risks associated with Thunderbolt 3. With its ability to transfer large amounts of data at high speeds, there is an increased risk of unauthorized access or data theft.
