> Per-domain email filtering for small businesses, MSPs, web hosts, law firms, accounting firms and real estate teams: the threats each faces and what helps.

The same filtering protects every domain, but the risks differ. A law firm worries about changed payment instructions, an MSP about many client domains, a host about support tickets. Start with the page closest to you.

iBlockSpam filters inbound mail at the MX level, in front of the platform you already use, and charges one price per domain. Every mailbox on the domain is included, so hiring doesn't change your bill. The pages below explain what that means for different kinds of business, including the limits.

## For businesses protecting their own domain

### [Small businesses](https://iblockspam.com/solutions/small-business)

Spam, phishing and malware filtering without per-user pricing, a personal quarantine for every user and guided setup for small teams without a security department.

### [Law firms](https://iblockspam.com/solutions/law-firms)

Phishing, spoofed senders and changed payment instructions aimed at client funds, plus what the ABA's ethics opinions say about reasonable safeguards.

### [Accounting and bookkeeping firms](https://iblockspam.com/solutions/accounting-firms)

Tax-season phishing, IRS impersonation, W-2 requests and malicious client attachments, with a checklist for busy season.

### [Real estate, title and escrow](https://iblockspam.com/solutions/real-estate)

Closing wire fraud, lookalike domains and the call-back process that stops a fraudulent wire even when a client's own mailbox is compromised.

### [Medical and dental practices](https://iblockspam.com/solutions/healthcare)

Phishing, malware and vendor impersonation aimed at patient data, what the HIPAA Security Rule says about email, and the questions to ask us first.

Firms that move money on email instructions should also read our guides to [business email compromise](https://iblockspam.com/blog/business-email-compromise-prevention) and [vendor invoice fraud](https://iblockspam.com/blog/vendor-invoice-fraud-payment-redirection).

## For businesses that look after other people's domains

### [Managed service providers](https://iblockspam.com/solutions/msp)

One filtering layer across clients on Microsoft 365, Google Workspace and cPanel, with drift alerts when someone changes a client's DNS.

### [Web hosting providers](https://iblockspam.com/solutions/hosting-providers)

Per-domain inbound filtering in front of the mail servers you already run, with notes for cPanel/WHM routing.

For MSPs and hosts, partner terms, including pricing, are agreed individually, and approved partners get a partner console for their clients' domains; see [partners](https://iblockspam.com/partners).
