More and more companies are embracing the cloud services due to its convenience and ease of use, and as file sharing is becoming an essential service for safe and easy data exchange, cloud computing is gaining even more popularity.

However, while cloud services offer many benefits to businesses, security can still be a major problem. Despite the obvious advantages of using the cloud, there are understandably some people with concerns about security and usability who are not ready to take the plunge. Therefore, when getting ready to implement cloud computing, it is extremely important to choose a reliable service provider. In this article, we will focus on three key points regarding security that you should always consider when choosing a cloud-based storage service.


1. Data center safety

When you use a cloud service, your data will be stored in the data center of the service provider. In terms of security, it is very important to check what safety and security measures are being taken in the data center.

One specific way to do this is to refer to the "Data Center Facility Standards" defined by the Japan Data Center Council. This set of standards was created to meet global realities but has been revised to address specific situations in Japan, such as its high levels of seismic activity. The standards are divided into four tiers (Tier 1 to Tier 4) and can be used to assess the service level of the data center.

As for data center location, you may wonder if domestic or international data centers are better. Each has its own advantages and disadvantages. In the case of’s domestic data center, it is located in Nagano Prefecture, which is considered to be less susceptible to natural disasters due to its location and geographical features. Also, it is classified as the Tier 3 level standard in the aforementioned Data Center Facility Standards.

What is the Tier 3 standard?

・A higher level of safety is ensured against disasters, such as earthquakes and fires, than in regular buildings.

・Redundant facilities are in place that can continue to provide computing services even if some facilities are temporarily shut down, such as for equipment maintenance.

・Access control to the building and server room is implemented.

・Operation reliability for assumed end users is 99.98% or higher.

Location affects data transfer rate

Data transfer speed can also be affected by the location of the data center. Although the actual specs can differ depending on each cloud service, as your data is actually stored in one physical location, the distance between you and your data can be an important factor in terms of speed and usability.

In this regard, the data center is ideally located in Nagano City in Nagano Prefecture in central Japan, where our head office is also based.

2. Service management system

In the cloud storage industry, there are a variety of ways that businesses manage their data storage and server maintenance. In order to avoid the risk of information leaks or compromise, it is recommended to choose a service that has the full range of information security measures and network redundancy. provides 24-hour support and complete security measures customer service is always available by telephone or chat from 10:00 to 17:00 (JST) to address your questions and concerns. Of course, you can contact us by email at any time.

In addition, in case of server downtime as a result of server trouble or hardware failure, emergency calls are accepted 24 hours a day.

In addition, has achieved stable operations with the highest standards of security policy, utilizing more than 20 years of experience in providing hosting services, such as network redundancy and in-house power generation facilities, in addition to thorough security measures certified by ISO27001 (ISMS).


3. Data transfer encryption

Encryption is an essential part of cloud service security. Instead of transferring data in its “raw” state, it is encrypted with one or more mathematical techniques and a password to maintain data confidentiality. As it is one of the strongest ways to keep your data safe, it is highly recommended to choose a service with the most up to date encryption.

What is AES-256?

In a nutshell, AES is one of the various methods of "encryption.” AES (Advanced Encryption Standard) is a new encryption technology that was approved by the National Institute of Standards and Technology (NIST) in 2001 that has become the current standard encryption algorithm for communication data. 

AES uses "symmetric key cryptography," in which the same encryption key to encrypt and decrypt (undo what has been encrypted) is applied. In this case, the longer the cryptographic key data used for encryption and decryption, the more secure it is. The length of the cryptographic key is called the "key length" and is generally expressed in "bits."

The previous standard was called DES (Data Encryption Standard), which had a shorter key length of 56 bits and was vulnerable to brute force attacks. In comparison, AES has a longer key length than DES, with a choice of 128, 192, or 256 bits. In other words, AES itself is the most secure encryption technology as of 2021, and AES-256, which has the longest key length, is the strongest encryption method at present.
