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).

Pricing positioning
dmarcian pricing scales with mail volume (messages/month), not domain count, which favours low-volume domains. PhishFence prices per-domain so your bill is predictable regardless of mail volume. Above ~100K messages/month, PhishFence is typically cheaper.
