How to publish your business on DNS-AID: a practical setup guide

Publishing your business on DNS-AID is not complicated, but the order matters: the goal is to become discoverable to AI assistants without accidentally exposing more than you intend. The DNS record is the easy part – the real work is deciding what your agent does and locking it down first. Here is a practical sequence an Israeli SMB can follow, ideally with help from whoever manages your domain and IT.

Step 1: Decide What Your Agent Should Do

Start with scope, not technology. List the handful of things you actually want an external assistant to be able to do on your behalf – share opening hours, take a booking, return a quote, open a support request – and deliberately leave everything else out. The narrower the agent's job, the smaller your risk and the easier everything that follows becomes. Resist the temptation to expose your whole system 'just in case'.

Step 2: Stand Up a Secured Agent Endpoint

Next you need a service that speaks an agent protocol such as MCP or A2A and implements exactly the capabilities you scoped. This can sit on top of your existing systems or run on a managed platform. Build in authentication, rate limiting, and input validation from day one – this endpoint will be publicly discoverable, so treat it like any other internet-facing service, with least privilege to the data behind it.

Step 3: Publish the DNS-AID Record

Only once the endpoint is live and secured do you add the DNS record that advertises it – typically a TXT record under a name such as _agent.yourcompany.co.il that names the endpoint and the protocol it speaks. Keep the record minimal and accurate. This is the step that actually makes your business discoverable, which is exactly why it should come after the agent behind it is ready, not before.

Step 4: Sign Your Zone With DNSSEC

Because the DNS-AID record is what assistants trust to find your real agent, protecting it from tampering matters. Enabling DNSSEC cryptographically signs your DNS answers so an attacker cannot quietly substitute their own endpoint for yours. Most Israeli registrars and DNS providers support DNSSEC, and turning it on closes off one of the few ways an agent could be redirected to an impostor.

Step 5: Test Discovery, Then Monitor It

Confirm that a compliant assistant can find your record, reach your agent, and do only what you intended – and nothing more. Then keep watching: log the requests your endpoint receives, alert on unusual volume or patterns, and review the published record whenever your services change so it never points somewhere stale. Discovery is not a set-and-forget step; it is a small new surface that deserves the same monitoring as the rest of your stack.

Common Mistakes to Avoid

The recurring errors are predictable: pointing the record at an over-permissioned endpoint that can reach far more than the task needs, leaving a record in place after the service behind it changed, skipping authentication because 'it is just an agent', and forgetting DNSSEC entirely. Each one quietly turns a useful capability into a liability. Avoiding them is mostly discipline, not extra technology.

Going live the right way

DNS-AID rewards businesses that adopt it carefully and early, but the value is entirely in doing it securely – a discoverable agent is only an asset if it cannot be abused. NetFortress helps Israeli SMBs scope, build, and publish their agents on DNS-AID end to end: hardening the endpoint, enabling DNSSEC, and monitoring what comes through.
