The Thought Put into wizSafe

Security Made Possible Because IIJ is an ISP

In 1992, IIJ was established as the first commercial Internet service provider (ISP) in Japan. Backed by world-leading network technology, we have continued to contribute to improving the security level of customer networks.

Operational Capability × Overall Capability

Total security that can only be provided due to IIJ's thorough knowledge of networks.

Operational Capability
by proven results

Our services benefit from the know-how we have built up over more than 20 years of running systems across thousands of devices in different forms, from hosting solutions to cloud infrastructure.

From backbone to endpoints

We offer security measures that make full use of our Overall Capability as an ISP, from DDoS countermeasures that are effective on the ISP side, to security intelligence based on backbone traffic, DNS queries, and vast quantities of logs from security equipment.

Security Initiatives for a Safe Society

Independent information gathering activities

At IIJ, we gather information to discover issues and incidents that occur on the Internet on a daily basis at an early stage, and implement measures on IIJ services as quickly as possible. These activities include accumulation of information on the handling of incidents that actually occurred through public monitoring of general news, collection of vulnerability information, and malware analysis.

Web Crawlers

Web crawlers are systems for observing malware that infects devices by exploiting vulnerabilities in browsers and their plug-ins. They monitor the Web pages of users in the IIJ network for malicious websites or code that redirects users to such websites, and take actions such as temporarily shutting down sites as deemed necessary.

MITF(Malware Investigation Task Force)

The MITF is a project for carrying out anti-malware activities that began from May 2007. Honeypots are installed within the IIJ backbone to observe network-based attacks and the status of malware activity. We implement countermeasures based on information acquired through recording attacks, as well as obtaining and analyzing specimens.
