The working group that first developed ARC adopted a logo as a way to promote awareness of the protocol. The logo featured a drawing of a seal, referencing the concept of “sealing” authentication results in the ARC headers.
The old ARC logo
In celebration of the publication of the ARC protocol as RFC 8617, a new logo has been developed. Feel free to use it to promote awareness and use of the ARC protocol. However, because this site and DMARC.org do not endorse commercial products, this logo may not be used it in a way that could be construed as endorsing any commercial products or services.
The new ARC logo
We hope this logo will support efforts to use ARC effectively on the Internet.
