Who it is for
Whoever owns a domain's email authentication and DNS records and needs a configuration check.
Radar Lite
Domain email authentication and DNS security checks
Overview
What Radar Lite does
Radar Lite is the domain assessment tool from Red Sift. Given a domain it inspects email authentication records, DNS setup, and web security configuration, then reports scores on a radar chart with a written summary attached.
Findings arrive ordered by priority and paired with remediation guidance, so the result is a list of what to fix rather than a bare grade. Several domains can be examined in one request, which makes comparison possible: the record gives the example of setting two domains' DMARC configurations side by side, and of assessing three at once.
Follow-up questions are supported after the first run, both for explaining terminology and for going deeper into a particular test.
What stands out
Several domains can go through in one pass, which turns a configuration check into a comparison.

Where Radar Lite is listed
Radar Lite is listed in the ChatGPT apps directory only. Red Sift has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Radar Lite's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Red Sift, and inclusion here is not an endorsement.
