dmarcian Alternative: PhishFence vs dmarcian

DMARC-first with the standard's history behind them.

dmarcian was founded by one of the DMARC spec authors and is the closest the industry has to an institutional reference implementation. Their DMARC reporting depth is excellent. PhishFence is broader-scope: we add lookalike monitoring, subdomain-takeover detection, and LLM analysis but go less deep on niche DMARC reporting features (like sub-account hierarchy).
