HetrixTools is a monitoring service for websites, servers, IP addresses and domain names. Its Uptime Monitor checks the availability of websites and servers from several locations worldwide and can use a lightweight agent on servers. Its Blacklist Monitor checks IP addresses and domains against blacklists, including Microsoft SNDS. Users sign up online and work through a web interface, so the service is delivered as hosted SaaS. According to the website, the company has been operating since May 2015.
The terms of service name HetrixTools, Inc. as the contracting party, with an address in Beaverton, Oregon, United States. The provider is therefore subject to US jurisdiction, including the CLOUD Act. The website does not state where customer data is stored. The privacy policy mentions logs held in Cloudflare Workers and Google Analytics, and says the company has taken the necessary measures to be GDPR compliant, but it names no hosting locations and no transfer safeguards. A European organisation should therefore request the data locations and a data processing agreement before use.
