Password exposure reported
A known breach source lists credentials among the exposed data.
A leaked password can open the door to your business.
Your company does not have to be hacked directly. A breach at a vendor or online service can expose email addresses and passwords your team uses elsewhere. LeakGuard monitors the business emails and domains you choose, alerts you to known exposure, and tells you what to secure next.
One finding. One explanation. A response your team can follow.

DMARC is a public domain setting that tells receiving mail systems how to handle messages that fail identity checks.
It reduces domain impersonation and phishing, but does not stop ordinary spam or prove a message is safe.
LeakGuard checks the public setting, shows the current status, gives the next safe DNS record when action is needed, warns before enforcement, and prepares instructions for the domain or email administrator.
Not protected
No public setting asks receiving mail providers what to do when messages fail identity checks.
Watching
The setting watches identity checks but does not ask providers to take enforcement action.
Quarantine requested
The setting asks receiving mail providers to treat failing mail as suspicious according to their systems and policies.
Reject requested
The setting asks receiving mail providers to refuse failing mail according to their systems and policies.
