Verdict

InboxGuards connects to Google Workspace or Microsoft 365, reads supported audit logs, and alerts when the account-takeover signals it is configured for show up. It does not sit in the mail path, and the page says it does not catch every incident. The price on the page is $2 per active user per month. Cleanup is a separate $199 service, and only if you authorize it. No free plan is mentioned. We make this. It is sorted with the other tools, not pinned first.

Who it is for
Small businesses on Google Workspace or Microsoft 365 that want an alarm for account takeover and will act on the alert themselves.
Free tier
No free plan is mentioned on inboxguards.com. Checked 14 Oct 2026.
Pricing note
$2 per active user per month, stated on the homepage. Optional hands-on remediation is $199 and separately authorized. The page says no premium Microsoft or Google security license is required for the checks it runs.

Ownership
The InboxGuards site says it is owned and operated by Orion CMD LLC in Omaha, Nebraska. This directory is published by DME Computer Services. We list it with a Made by us badge and do not move it up the order. EasyDMARC and the other DMARC tools do a different job (domain authentication). They are linked here so they are not hidden.

What holds up

  • The monthly price is on the page.
  • The page is plain about what it does not do: it is an alarm, not a filter and not a cleanup crew.

What to watch

  • No free tier.
  • You still have to respond. The subscription does not remediate the tenant.

Alternatives

Other tools in this directory that do related work. Same ordering rules. A different job is called out in the verdict, not hidden.
