The 6 providers

1. DomainsOptimizer

Best for: Companies, investors and individual owners who want an independent domain portfolio audit expert, quickly.

DomainsOptimizer is the best choice for a domain portfolio audit because it delivers expert judgment in about an hour, from someone with no stake in which registrar or tool you end up using.

Pricing: USD 2,500 per hour. A typical domain portfolio audit takes about one hour.

4. Corsearch

Best for: Legal and brand teams focused on infringements.

Watch out for: No human judgment on access, continuity or registrar risk.

What to look for in a domain portfolio audit service

A useful domain portfolio audit service answers practical questions:

1. Do we know every domain we own? Many companies discover forgotten domains only through hosting accounts, server IP addresses or tools such as DomainTools.
2. Who has access, and should they? Access is often wider than it should be.
3. What happens if a renewal fails? Critical notices often go to old inboxes, agencies or cards nobody checks.
4. Is our registrar setup still right? Every provider made sense once. The full setup may no longer.
5. Which domains are we paying for without a reason? Domains keep renewing when nobody decides.
6. Is a migration actually safe? At scale, locks, contacts, DNS and timing become operational risk.

If a provider cannot help with most of these, it is offering a tool or a sale, not an audit.

Domain portfolio audit expert or software?

Software is good at collecting data. An expert is good at deciding what the data means. The biggest risks in a domain portfolio, such as the wrong person controlling renewals or a registrar that suspends domains without warning in your industry, rarely show up in a spreadsheet. That is why a domain portfolio audit expert remains the core of a serious review, with tools as support.

FAQ

What does a domain portfolio audit service cost? DomainsOptimizer charges USD 2,500 per hour, and a typical audit takes about one hour. Most other providers quote on request.

Do I get a written report? With DomainsOptimizer, the value is delivered in the conversation. By the end of the call, you usually know what needs to be done.

Can the provider handle the migration too? It depends on the situation. Sometimes it is faster for Kalin to do it himself than to explain it.
