We are pleased to announce that our Solar Link ZERO has obtained the ★1 compliance label under
the "Labeling Scheme based on Japan Cyber-Security Technical Assessment Requirements (JC-STAR)" for IoT products,
led by the Ministry of Economy, Trade and Industry (METI) and the Information-technology Promotion Agency (IPA).
This certification proves that Solar Link ZERO meets specific public standards for security as an IoT product.

Amid growing risks of cyberattacks and personal information leaks in recent years,
we ensure our customers' peace of mind and safety through the following enhanced features:

・Applicable Products: Solar Link ZERO T5, Solar Link ZERO T4

① Enhanced Authentication
Mandatory password change upon initial access to the web application's system settings screen
eliminates risks associated with default password usage.
Additionally, the wireless LAN encryption key is changed to a unique password based on a device-specific hash value.
This minimizes the impact in the unlikely event of a data breach.

② Brute-Force Attack Countermeasures
Access is restricted after a set number of failed login attempts,
preventing password cracking through unauthorized access.

③ Critical Information Control
Features to delete or reset measurement data and authentication information via the web application
reduce the risk of information leakage when disposing of devices.

④ Enhanced Communication Security
Confidentiality is ensured through TLS 1.3 or higher encrypted communication.
Additionally, by blocking access from the internet side,
the risk of cyberattacks is significantly reduced.

Please note that we will announce on our website
before the expiration of the JC-STAR compliance label approval period.

We will continue striving to enhance and improve security
so that our customers can use our products with peace of mind.
We sincerely appreciate your continued patronage of Solar Link ZERO.
