1. Out of the following, what do you feel is the most important aspect to consider when developing IoT solutions?
Results:
- Security 47%
- Communication reliability 23%
- Ecosystem 13%
- Edge device reliability 10%
- Ease of data review/analysis 7%
Our latest survey shows 47% people consider data security and protection the most important aspect when considering IoT solutions (dropped by 5% compared to last year’s results). Suppliers and developers are more vigilant than ever before and working hard to implement the best possible encryption and security technology to make their solutions uncompromisable. Communication reliability still remains the second biggest concern; IoT means connected devices and connection reliability can’t be overlooked.
2. What is your key concern regarding IoT?
35% of respondents think security is the major concern for any IoT implementation, mainly due to the type of data collected from the things (machines) and humans, which is very sensitive & personal. We can expect to see more and more encryption everywhere. Businesses who initiate IoT projects treat IoT security as their top priority.
3. What do you believe will be the top IoT Industry in 5 years’ time?
We have a tie between Home Automation and Industrial Automation & Control with 22% being the top two IoT market verticals in the next 5 years. This is not a surprise; we are already surrounded by such smart devices in our daily life, talking to smart speakers (Amazon Alexa or Google Home), relying on smart home appliances and smart security to look after our house when we are away. Even in the IIoT space, more and more manufacturing facilities are converting to full automation. From robotic manufacturing and assembly, to fleet management and predictive maintenance in order to reduce break downtime, all the way to end customer delivery.

4. Did or do you use a third party for any part of your IoT systems design?
| No | 46% | |
| Yes | edge to cloud communication | 30% |
| Yes | designing edge devices | 26% |
| Yes | data centre/analytics | 21% |
Build vs Buy is a critical decision for any business, both options have pros & cons. The survey shows developers still prefer to design a complete edge-to-cloud & security solution by themselves (46%), instead of relying on third-party providers. However, the “build” option has dropped by 12% compared to last year (dropped from 58% last year to 46% this year). Developers understand the critical importance of an IoT platform to efficiently, securely and economically support their IoT applications, but things are getting complex and require a new skill set each time a solution is being developed, which is not always possible to find in house.
5. Who do you believe should own the data gathered by edge devices?
| User who’s data is gathered | 70% |
| Company who implements IoT system | 26% |
| External governing body | 4% |
Security is the critical element in any given IoT implementation, industrial or consumer related. Questions surrounding data ownership are always the topic of discussion – who should own the data? With no change in results compared to last year, 70% of the users like to own the data collected by the edge device, rather than these being owned by the IoT solution provider. However, 26% of respondents indicated that they are happy with the solution provider owning the data collected, provided there are regulations on how they are stored and used.
6. What one factor do you think would most accelerate the benefits of the IoT?
| Interoperability – certifying standards | 35% |
| Ease of development | 35% |
| Need for Open Standards | 32% |
| Connectivity Standards | 32% |
| Need for data Privacy Policy | 24% |
| Adoption by public sector | 18% |
| Energy Consumption | 17% |
We hear about IoT everywhere but the reality is the internet of things still has a long way to go; this is just the beginning. Comparing the results from last year, interoperability (35%) and ease of development (35%) remain the two key accelerators for IoT implementation, and both are directly connected to each other. Forming the standard or protocols to follow will make IoT implementation much easier; machines and devices of all kinds will be able to understand each other and use collected data/information.
7. How likely would your company be to take on the lead role of building an IoT product itself?
| 0 - 25% | 43% |
| 26% - 50% | 24% |
| 51% - 75% | 16% |
| 76% - 100% | 16% |
IoT industry is growing rapidly but still has to overcome a few major challenges in security, interoperability, connectivity and data ownership. Nonetheless, the industry seems to address these challenges better than ever; we are seeing more people having higher levels of confidece to lead the IoT market (jumped from 9% last year to 16% this year). Also we see a decrease in the percentage of companies who were less confident to contribute to the IoT market (from 54% last year to 43% this year), which means confidence in the technology is increasing.
