The few tools that cannot work in a browser (such as WHOIS, subdomain enumeration, bulk email validation, ASN lookup and ping) use a small relay protected by a rotating HMAC-SHA256 token, strict per-IP rate limiting and an SSRF guard that blocks private and reserved ranges. Query content is never stored. No analytics, no telemetry, no third-party scripts. Admin Tools is built and maintained by Cloud Captains, a Google Workspace partner based in the Netherlands and active across Europe. We are an independent European company, easy to reach, with real people behind the product.

Netlas.io
The Netlas plugin gives information about where the website is hosted, who owns the IP and what other services and ports are open. This extension is intended to facilitate the work of specialists of the information security. Do you do Bug Bounty? Or is your field of activity - OSINT? Undoubtedly, our plugin will be useful to you. The plugin will allow you to get information about the website you are currently browsing at any time. Just click on our blue spider, and the extension will show you the IP address and domain name details. You will see the location of the object under study, its owner, open ports, and installed services. The extension receives all information from the Netlas.io service, and you can also go from the results to it to get acquainted with the data in more detail: examine the full WHOIS response, view responses, and all DNS records. In addition, the extension can work in automatic mode, passively querying each site you open in the Netlas database and checking for vulnerabilities. To do this, simply enable Smart Logo in the extension settings, then reload the page. Now, every time you visit a site that is potentially vulnerable to some known CVE, the extension logo will change color depending on the vulnerability rating. Attention: the free use of the extension is limited to thirty requests per day without the ability to automatically scan visited sites. To expand the possibilities, you need to register on netlas.io and use your API key.
