Can we tell a business sign-up from a consumer one?

Yes, on a paid plan: company.type says whether the organization is a business, an ISP, a host, a school or a government, as asn.type does for the network.

Will remote workers behind a corporate gateway be blocked?

Not if your rule lets relays through: enterprise gateways such as Zscaler answer is_relay, apart from VPNs, on every plan.

Can we enrich the sign-ups we already have?

Yes. Stored addresses look up the same way, 1,000 a request on a paid plan, and the answer is today's rather than the one from the day they signed up.

Do we need a key to start?

No. Unlimited answers the company, the country and an email domain's records with no key, so the form check can ship first. A free key's first 100 lookups each day answer every field.

Know which company each sign-up is from.

A sign-up form gets an email and an address. One lookup says which company's network it came from, where it is and whether it hides behind a VPN or a proxy, and a domain lookup whether the email is a throwaway.

Account enrichment
A sign-up arrives from a personal email with no company name. Read the company behind its network, and route business sign-ups to sales.
Answered bycompanycompany.type
Free-trial abuse
One person opens trial after trial from VPN exits and new inboxes. Ask for a card when the address or the email is disposable.

Data residency
Customers in the EU expect their data to stay there. Put each new workspace in the region its sign-up came from.

API key farming
Free API keys get farmed from hosting servers to pool quotas. Hold keys created from hosting networks for review.

Company, place and abuse signals in one answer.

The company, the country and continent, Tor, relays and an email domain's records answer with no key and no daily or monthly cap. VPN, proxy and hosting flags, the company's type and the disposable flag come with every paid plan, and Pricing lists every field by plan.

Check each sign-up before it costs you anything.

01
On the sign-up form
Look up the address and the email's domain before the account exists. A disposable inbox or a VPN asks for a card, and everyone else goes straight in.
02
In the CRM
Attach the company and its type to each new account. Sales sees which sign-ups come from a business network before anyone reaches out.
03
When a workspace is created
Place it in the region its sign-up came from, by country or continent. Keep the customer's own choice when they make one.

Does company name the person's employer?

It names the organization using the address. On an office or campus network that's the employer or the university; on a home or mobile line it's the ISP.
