Before you start.

What Authex can see, what it can change and what it costs.

What does Authex actually do?

Authex is an autonomous agent that manages your company's email security. It watches for drift, makes supported changes within the authority you give it, verifies the result and records the evidence.

What can Authex see before I connect anything?

A public scan can check supported domain and email settings without an account. It cannot see private services, people or access, and it makes no changes.

Does Authex read my email?

No. Authex reviews supported configuration, forwarding, administrator access and connected applications. It does not read email messages, and you can revoke connected access.

What can Authex see after I connect email?

Supported platform reviews can show forwarding, connected applications, administrator access and sign-in protection. What Authex can see depends on the platform and permissions you approve.

Could a change block real email?

A real sending service can be affected if it is unknown or configured incorrectly. Authex shows known and unknown senders first, applies only supported changes you approve, checks the result and records what happened.

What happens when my company no longer needs email on a domain?

Email Services Retirement helps you find remaining email dependencies and record what must move or stop. The domain stays registered and monitored; Authex retires its email services, not the domain itself.

What does the compliance evidence include?

It records what Authex checked, when it was checked, what changed, who approved it, the result and anything that still needs attention. It supports a review; it is not a certification or legal opinion.

How much does Authex cost?

Monitoring supported public checks is free. Enforce is £19 per managed domain each month. Pricing is per domain, not per user, seat or mailbox.

Can an MSP use Authex for clients?

Yes. MSPs use the same Authex product across separate client businesses. Start with a two-client pilot, then move to volume pricing when the operating model fits.
