About DataFence - Data Loss Prevention

**What's New in Version 1.2.2** Request an Exemption When a File Is Blocked - When an upload is blocked on a site that isn't on your organization's allow-list, you can now request a one-off exemption right from the block notice — add a business justification and submit. - Your request goes to an administrator for review, and you get a tracking reference (e.g. EXM-000123) on the spot. - Once an admin approves it, simply retry your upload — the approval takes effect immediately, no waiting. Approvals are specific to that exact file and site, and an admin can revoke one at any time. - Enforcement stays server-side: the extension never approves an upload on its own, so an exemption can't be faked or forced from the browser. Refinements - Clearer block notices — after you submit an exemption request, the notice confirms your reference and next step without leftover buttons. - Modal suppression on non-verdict — when a safety check returns no verdict, no block modal is shown; protection still applies. - Exemption request form now displays your typed justification clearly on every site, regardless of the page's styling. - General reliability and polish across the upload and text-monitoring flows.
