A design pattern for holding on to bad rows so they can be examined, rather than a built-in feature. A warning expectation captures metrics, a computed column flags the rows, and separate views serve the valid and invalid data.

Terms in this definition
- Pattern
A reusable answer to a recurring problem that places building blocks in context, explaining when, how and why to apply them and what compromises are involved.

Related terms
- AcrQuarantineWriter
Azure Container Registry built-in role belonging to the quarantine feature: it lets an identity push quarantined images and update their quarantine status. It has nothing to do with signing.
- Anti-malware policy
Scans mail attachments for malware as part of Exchange Online Protection, sending anything infected to quarantine. The common attachments filter may reject chosen file types, and you can add custom policies for particular users, groups or domains on top of the default.
- Anti-spam policy
Exchange Online Protection uses this policy to filter junk both arriving and leaving. Every cloud recipient falls under the default; custom versions can aim at users, groups or domains. Among the possible verdict actions is quarantine, held for between 1 and 30 days.
- Auto-quarantine
When a restricted app such as a cloud sync client touches a sensitive file, this Endpoint DLP action relocates the file to a quarantine folder the admin picks, optionally leaving a .txt placeholder behind. That stops the app repeatedly retrying.
- Honor DMARC record policy
When on, the DMARC policy that a sending domain publishes determines how a message is handled, in Defender for Office 365 and Exchange Online Protection anti-phishing. A different action can be chosen for p=quarantine than for p=reject.
- Proactive HA
When a hardware vendor's monitoring reports degraded health on a host, for instance a dead power supply, this vSphere capability clears VMs off it and moves the host into quarantine or maintenance mode. DRS has to be enabled for it to work.
- Stop and quarantine file
Ends running processes for a file, moves it to quarantine and cleans up persistent data like registry keys, across up to 1,000 devices that saw it within 30 days. For a lasting block, create a file indicator.
