Protecting Customer
Information
We rigorously manage and monitor security to safeguard customer information from leaks and cyberattacks and to provide our customers secure products and services.
Rigorous
information management
SoftBank has established five-tiered security areas ranging from level 1 to 5 in our facilities, applying strict controls in accordance with each level. Levels 3 and above are considered “high-security areas.” Significantly important data, such as personal information and telecommunications secrets, are exclusively handled in these areas.
For example, in the Customer Support Center, which is designated as a high-security area, we strictly control security under the rules specifically designed for these areas, authorizing entry and exit to the facilities by security guards and passes, and keeping prohibited items from being brought in to the facilities.
Additionally, our operations fully adhere to ISO27001, the international standard for information security management systems. We undergo an external audit twice a year based on ISO27001 to confirm that our information security management is appropriately run, including compliance with our Privacy Policy.

Security monitoring
To protect our customers' information and the equipment used to provide telecommunication services, security analysts are monitoring security at our Security Operation Center (SOC) 24 hours a day, 365 days a year.
As for countermeasures against cyber attacks, we monitor things like DoS attacks on facilities which provide communication services, intrusions into devices connected to the facilities, detection of malware infections on business computers, access to unauthorized sites, attempted exploit vulnerabilities in internal systems, etc. In terms of countermeasures against threats from inside our company, we monitor the operation of work computers by employees and prevent operations which might lead to unauthorized removal of data.
Protecting usage
environment of customers
We make a variety of efforts to provide our customers with comfortable experiences in their use of our mobile phone, smartphone and Internet services.
Security measures
We provide a variety of security measures to protect our customers from potential risks, such as viruses, spyware, and one-click fraud.
Spam mail
To protect against malicious e-mails such as spam and fake bills unexpectedly sent to mobile phones or smartphones, we automatically examine the content of these e-mails based on our accumulated database of spam and provide our customers with spam filters that block the receipt of these kinds of e-mails. We have also set up a reporting center where our customers can report any spam e-mails they have received by simply forwarding them. When it is confirmed that they were sent from a SoftBank registered address, we may take strict measures against the address owner, including suspension or cancellation of our service.
Unauthorized access
There are increasing cases of malicious third parties gaining unauthorized access to personal information, such as bank account numbers, credit card numbers, and login IDs and passwords, after customer devices are infected with viruses or they access URLs in the bodies of e-mails. We are strengthening security to protect our customers' personal information by preventing stolen information from being used for unauthorized access to My SoftBank and My Y!mobile member sites, where they can manage their accounts.
Passcode
Customers can change their settings in such a way that the passcode they specified when signing the contract is required for logging into My SoftBank or My Y!mobile.
One-Time passwords
When a customer uses a payment option called SoftBank/Y!mobile Matomete Shiharai, SMS (e-mail) is sent to his/her phone with an authorization code. This code is valid for one time only, and is only known to the registered user.
Unauthorized access
In order to prevent unauthorized access, such as identity impersonation, when a customer attempts to use some options available on My SoftBank or My Y!mobile membership sites, we may send a SMS or e-mail to confirm his/her status in the of usage of our services.
