Domains — FAQs

Quick answers to common questions about domain security & management.

Do you support multi‑registrar portfolios?

Yes. We audit, consolidate where sensible, and enforce consistent policy (locks, 2FA, contacts, renewals) across registrars.

Can you move us to DMARC p=reject safely?

We use staged rollout with rua/ruf reporting, alignment tuning, and sender inventory to avoid breaking legitimate mail.

Do you automate certificates?

We implement ACME for issuance/renewal, enforce HSTS, and rotate keys with audit trails.
