Protecting internal information assets with Nets Wireless, a step forward in security measures

With the spread of the Internet and the advancement of IT technology, the Internet and IoT devices have come to be used in various businesses. While technological innovation greatly contributes to improving operational efficiency and profits, it also creates new challenges and risks.

In IoT devices that need to send and receive large amounts of data, network delays may occur and affect business operations. In addition, the use of the Internet for business also creates security risks such as information leakage. The corporate MVON "Nets Wireless" provided by NEC Networks & System Integration will help solve these problems.

In this article, we will introduce the characteristics and use cases of "Nets Wireless" that can transmit and receive data without delay and build a secure environment.

Why you should choose a network that is essential to your business with a focus on security

Nowadays, with an increasing number of companies promoting DX and introducing telework, any business uses the Internet and devices to do business is to be performed. There are quite a few companies that utilize a large number of IoT devices.

In IoT devices, there may be some companies who are worried about security because they must be constantly connected to the Internet and send and receive large amounts of confidential information. Against the backdrop of an increase in cyber-attacks that actually exploit IoT devices, the Ministry of Internal Affairs and Communications is currently issuing a warning regarding security measures for IoT devices.

Even in telework, which has become widespread due to the corona crisis, it is necessary to take more security measures than ever before, as various types of information, which are corporate assets, will be handled outside the company. According to the Ministry of Internal Affairs and Communications' "secondary survey on telework security," about one in two companies answered that "ensuring security" was an issue in introducing telework.

Even if you know that security measures are important from the perspective of risk avoidance in management, it is extremely difficult to implement security measures for all the devices you use. If you try to deal with it by purchasing a new device or introducing various solutions, many companies will hesitate to start because it will cost a lot.

What I want to consider is the review of the network. By simply installing a network with high security, security measures can be implemented for all devices that use the network. If you just change the network, you don't need to buy new devices or implement security measures for each device, so the burden on management can be reduced. Another advantage is that employees can continue to work as before without being overwhelmed by new devices and solutions.

"Nets Wireless" provides strong security using a closed network

"Nets Wireless", a corporate mobile network service provided by NEC Networks & System Integration, uses a closed network that does not connect to the Internet. A service that allows you to send and receive data. Since it is not connected to the Internet, it is possible to build a secure business environment simply by switching from the existing network to Netz Wireless.

When accessing the internal server from an external smart terminal or personal computer, monitoring and controlling remote equipment, and sending images from drive recorders can also be done via a closed network. You can rest assured even when using IoT devices or working remotely to handle confidential information.

Nets Wireless is an MVNO that uses NTT DoCoMo's lines, but because it is for corporate use, unlike consumer use, the communication speed does not decrease during times of high usage such as commuting hours and nighttime. In addition, since there is no communication volume limit such as "3 GB in 2 days", stable communication can be used for daily work.

Nets Wireless offers a trial SIM, and it is also an advantage that you can try the actual usability before full-scale introduction. First, test using a trial SIM on some devices, and if the test is successful, full-scale introduction will reduce the burden on management. A network with high security and no delays can provide both peace of mind and operational efficiency.

Supporting the realization of DX with a safe and comfortable network and various services

Nets Wireless can be used in a variety of devices and businesses. Companies with multiple locations, companies that introduce telework, and companies that use many IoT devices such as transportation and manufacturing industries can use safe and high-quality mobile networks.

For companies with multiple locations, it is possible to build a safe and comfortable work environment as if the company LAN was extended nationwide. With telework, there is no need to let employees use their home networks or prepare mobile routers and lines for employees without an internet connection.

Companies that use IoT devices, such as those in the manufacturing and transportation industries, have the advantage of not having their work delayed due to data transmission delays, and being able to take measures against information leaks at the same time. You can select a plan that matches the usage conditions of the company that introduced it from a wide variety of network configuration proposals, so you don't have to worry about putting pressure on management with installation and running costs.

Another feature of Netz Wireless is that it can be installed in as little as one week because no construction work is required. It can be said that it is a service that meets the expectations of companies that want to immediately implement security measures and switch to a comfortable network.

Nets Wireless not only builds networks, but also provides operation and maintenance management services. It is also recommended for companies that want to proceed with DX but are worried about the network and cost. It is also suitable for short-term use such as demonstration experiments for developing and selling new solutions and limited-time events.

In addition, if you combine Nets Wireless with a multi-factor authentication service that can also use biometric authentication, you will not need to enter your ID and password, and even if your device is stolen, your information will not be stolen by a third party. This is because with multi-factor authentication services, only a combination of a registered computer and a user associated with that computer can access the network. Employees' personal devices will also be unavailable, so they will be freed from worries about security risks during telework.

Usage examples of Nets Wireless

In what kind of situations can these advantages of Nets Wireless be utilized? From here, we will introduce specific examples of Nets Wireless usage.

Disaster prevention management by local governments

In order to protect the safety of the region during heavy rains and typhoons, each local government monitors the conditions of rivers and mountainous areas and disseminates disaster prevention information. Surveillance cameras and sensors are used there. In order to ensure the safety of local residents, it is important to obtain real-time information. In the unlikely event that there is a delay in sending and receiving data, the issuance of warning information and evacuation orders may be delayed.

By using Nets Wireless to send and receive data from cameras and sensors installed in rivers and mountains, it is possible to send and receive data securely and without delay. Of course, it is also possible to build a network that mixes wireless and wired networks where a wired network is required.

In addition, by using network operation, monitoring, and maintenance management services, it is possible to operate surveillance cameras safely and smoothly even if local government officials do not have the know-how.

For monitoring renewable energy and new energy facilities

With the global shift away from fossil energy, the use of renewable energy and new energy is expanding. Even under such circumstances, there are many cases where patrols and inspections of photovoltaic power generation and wind power generation are performed manually. Many companies would like to improve the efficiency of patrols and inspections and reduce costs.

Using IoT devices and Nets Wireless enables DX in patrol and inspection work. By conducting patrols with surveillance cameras and acquiring various data on facilities from IoT devices, not only can work efficiency be greatly improved, but maintenance costs can be greatly reduced.

In a telework environment

Security measures, which many companies that have introduced telework feel to be an issue, can be easily implemented by using Netz Wireless and multi-factor authentication services.

If you use the multi-factor authentication service, only the registered computer and the user associated with that computer will be able to access. In other words, even if the laptop is lost or stolen, a third party cannot steal confidential information from the PC.

One of the strengths of Netz Wireless is the ability to build a telework environment regardless of the size of the company. A secure network environment can be prepared simply by inserting a SIM into the device, so there is a high possibility that the time and cost required to introduce telework can be greatly reduced.

There is no need to replace devices or prepare a network environment at the employee's home for telework, so the burden on employees can be reduced. In addition, it will contribute to operational efficiency by sending and receiving data without delay.

Security measures that can be started while reducing time and money!

Now that networks are being used for a variety of tasks, security measures are an issue that all companies should address regardless of their size.

If you are worried that you don't know where to start, consider reviewing your network first. With Nets Wireless, it is possible to use a network configuration and plan that matches the actual situation of your company with a wide variety of network configuration proposals and contract plans.

Even companies that want to implement security measures while keeping costs down as much as possible can use the Netz Wireless free trial to verify the connection in advance before starting full-scale operation. Let's try the safety and comfort of Netz Wireless with a trial SIM first.
