From NoVirusThanks
We've created some web tools for SOCs, researchers, webmasters and sysadmins:
Online Network Tools for SOCs, CERTs, Webmasters | NoVirusThanks

Here is a screenshot:


Will update this thread when we add new web tools.

Today (6 June) we've added URL/Link Extractor:
Extract URLs/Links from any Web Page, Online URL/Link Extractor | NoVirusThanks

And this one was added a few weeks ago:
DNS Security Services Checker (Quad9, Strongarm, Neustar, Yandex.DNS, etc) | NoVirusThanks

May be useful to some forum members too.
