Better Quarantine UI than in Defender portal

(Un)Quarantine with much better User Interface while having Total Privacy

We spin up a dedicated PowerShell worker just for you, stream your quarantine straight to Your control! We tear it down when you’re done. No disks, no indexing, no leftovers.

No mail stored or logged Private isolated session Instant type-to-search in memory

We do not store any of your e-mails – processing happens entirely in memory during the active session. Processing happens only the time session to Microsoft® services are alive still.

Subscriptions are live - 1 customers are already active. Activation links arrive within a minute of subscribing.

Purpose-built for fast quarantine review.

In-memory only

Every worker streams into RAM and disappears once your window closes. There is zero persistence for the mail you inspect, matching the policy we enforce across every tenant.

Easy login to backend

Copy code to clipboard for easy connect to E-mail Quarantine at Microsoft Defender. There is No API available so we have to do it the hard way though Powershell (but it Is secure)!

Great preview with links checker

We have nice preview with source view, "normal" view and safe link checker - You will get notification in preview modal if there are suspicious external links with extra info.

Killer feature: clear batches in seconds.

Combine lookalike messages, release or delete them in one sweep, and keep a transparent audit trail (host, device code, decision) without ever storing the message body.

  • Similarity scoring groups lookalike messages so you can clear batches at once.
  • Preview runs in a sandboxed iframe with its own CSP.
  • Search-as-you-type runs in memory on the worker — nothing leaves RAM.

Automation ideas on the horizon.

We are experimenting with AI co-pilots and rule-based releases running quietly in the background for the Atlas tier. No promises yet — we will only ship when it’s safe, auditable, and keeps everything in memory.
