Screen-Sharing Privacy for Lawyers: Protecting Privileged and Client Data

7 min read

Sharing Clio, a document, or a filing portal on a call can expose your whole case list, matter names, settlement figures and privileged material. Here's how to show one matter without revealing the rest — a practical guide, not legal advice.

When you share your screen with a client, co-counsel, opposing counsel or a court, you must protect every matter that isn't the subject of that call — client and matter names, privileged communications, settlement figures and opposing-party details all sit one scroll or one tab away. The safeguard is to blur the case list and any confidential material you're not presenting before you share, so a stray notification or a switch between windows never becomes an inadvertent disclosure. Confidentiality is a core duty — ABA Model Rule 1.6 and its state equivalents call for reasonable efforts to prevent unauthorized disclosure of client information — and blurring is one such effort during a live share.

  • Client and matter names — the matter list and global search in Clio, or the folder tree in your document system, name clients and matters you have no reason to show on this call.
  • Privileged communications — email subject lines and message previews, and notes in your practice-management system, can reveal privileged strategy at a glance.
  • Settlement figures — numbers in a demand letter, a spreadsheet or a billing screen that the other side or an unrelated client should never see.
  • Opposing-party and third-party details — names and information about adverse parties, witnesses and non-parties tied to other matters.
  • Confidential exhibits — documents under seal or a protective order, or unredacted exhibits open in another tab.
  • Trust-account and billing data — IOLTA balances, client invoices and outstanding amounts in your billing module.

The riskiest moment: opening one document or matter

The everyday scenario is a client or opposing-counsel call where you want to walk through a single document or one matter. But in Clio you reach that matter through a dashboard and a global search that list every other client and matter; in your email you scroll past privileged threads for other cases; in a filing portal your case list loads before the filing you meant to show. A notification, an autocompleted search, or a tab you forgot was open is all it takes to disclose something privileged or confidential. Blurring lets you present the one document or matter and keep the rest of your practice frosted.

How to share a matter or document safely

  1. 1

    Share one tab and silence alerts

    Share the single browser tab with the matter, document or portal — never your whole screen — and turn on Do Not Disturb so email and calendar notifications naming other clients don't appear.

  2. 2

    Blur the case list and search

    With BlurFirst, box-blur the matter list, the dashboard and the global-search bar in Clio (or the folder tree in your document system) so navigating never reveals other clients. The blur is rendered into the page, so Zoom, Meet, Teams and Loom capture it, as do screenshots of the feed.

  3. 3

    Element-blur the confidential lines

    On the document or matter you're showing, click to blur the fields you don't need to reveal — opposing-party names, a settlement figure, a privileged note — and click again to reveal one if you choose to disclose it.

  4. 4

    Check for identifiers with Scan

    Run the one-click Scan (Pro) to catch exposed patterns — SSNs, account and card numbers, emails and phone numbers — on the page automatically before you begin.

  5. 5

    Save a profile and keep panic ready

    Save a per-site profile (Pro) so your case list and sensitive fields re-blur each session and after the page re-renders. If privileged material appears, press Ctrl/⌘ ⇧ H to blur the whole page instantly.

Honest limits

  • BlurFirst blurs content inside a browser tab — the web versions of Clio, Outlook, Gmail and most e-filing portals qualify. It can't blur a native desktop app, a standalone PDF viewer or another window, so keep those closed (a desktop app is in development).
  • Scan detects patterns — SSNs, account numbers, card numbers, emails, phone numbers and API keys — locally. It does not recognize client, matter or party names, so blur those with box or element blur yourself.
  • Blurring is one safeguard, not a compliance program. It complements — never replaces — access controls, encryption, protective-order procedures and your firm's confidentiality policies.

Frequently asked questions

How can lawyers protect privileged information when screen sharing?

Share a single browser tab, turn on Do Not Disturb, and blur your case list, global search and any privileged or confidential material you're not presenting before you share. Because the blur is painted into the page, Zoom, Meet, Teams and any recorder capture it, so a scroll, a notification or a tab switch can't inadvertently disclose another matter.

Is inadvertent disclosure during screen sharing an ethics problem?

It can implicate your duty of confidentiality. ABA Model Rule 1.6(c) and its state equivalents call for reasonable efforts to prevent unauthorized or inadvertent disclosure of information relating to a client. Controlling what's visible during a live share is a practical part of that effort. This is general guidance, not legal advice — check your own rules of professional conduct.

Does BlurFirst upload any client documents or data?

No. Everything you blur stays in your browser and is never uploaded or screenshotted. Per-site profiles store which element you blurred — a CSS selector — never the privileged content inside it. The only network request BlurFirst makes is a license check.

Can I blur a PDF exhibit before sharing it?

If the PDF opens inside a browser tab, yes — box-blur the confidential passages before you present. If you open it in a standalone desktop PDF viewer, BlurFirst can't reach it, so view sealed or privileged exhibits in the browser or keep them closed.

What if opposing counsel asks to see something I've blurred?

Click the element to reveal it, then click again to hide it. Element blur is a toggle, so you can disclose one line you intend to share without exposing the rest of the matter or your case list.

Blur it before you share it.

Hide any field, region or message on a page before your next call. Nothing you blur leaves your browser.
