Frequently asked questions
What counts as a domain?
Each root domain (e.g. acme.com) counts as one toward your plan limit. Subdomains scanned under it are included at no extra cost on every plan.
How do I get started?
We're in early access. Contact us and we'll get your account set up. All plans are paid from day one — pricing is included with your onboarding.
Can I change plans mid-month?
Yes. Upgrades take effect immediately and are prorated. Downgrades apply at the start of your next billing cycle.
How is alert delivery handled?
You bring your own Postmark server token for email delivery and your own Slack webhook URL. Alert delivery cost scales with your own accounts.
