Data Center

The servers are located in a data center with 24/7/365 surveillance and security.


Our server has Linux installed.

Auto Updates of Security Patch

We maintain security by updating the server software to protect our users from security problems automatically.

We also have a reliable security system even if server software updates cannot occur automatically.

Disabling unnecessary services and ports

We disable unnecessary services that are initially programmed to start by default. We also publicize the minimum numbers of ports.


A firewall prevents unauthorized access to the server.

Encrypted data transfer by SSL

With SSL, the communication between the web browser and the server is encrypted. It helps to prevent your data getting lost, being edited, or spoofing.

Cacoo Security

Cacoo strives for higher security. We always verify the common attacks (such as XSS).

If there are any problems, we notify our users on the “bugs and requests” or “system failure information” websites immediately and deal with these problems promptly.
