External marketing help runs on your screen. The content agency reviewing drafts over a call. The ads freelancer walking the account. The SEO contractor getting the analytics tour. Every session is a view into the company — and the view is scoped by whatever the founder remembered to close, which on a busy Wednesday is not much.
The Standard Setup (And Why It Fails)
"I only share the relevant tab."
Why it fails:
- Marketing sessions wander: "Let me pull the numbers" — and the pull-up passes through revenue dashboards, the CRM, the calendar.
- Window titles narrate the company: "[Company] — Analytics — Revenue," "Stripe — [Company]," readable in every switcher frame — the contractor learns your stack and your numbers from the chrome.
- Notifications: a churn alert, a board email, a customer complaint — over the shared screen, in front of an external party.
- The contractor's own recording: they record the walkthrough for their team — your screen, in their archive.
Least access applies to screens exactly like systems — and contractors get system least-access while screens run wide open.
The NoCapture Setup for External Marketing Sessions
Cloak by engagement scope. Content review: the drafts and the content calendar visible; revenue, CRM, cap table, and internal comms cloaked. Ads walkthrough: the ad account visible; the rest of the business below the capture line. The contractor sees exactly the engagement's scope, enforced by the screen rather than by the founder's focus.
Mask the titles. Every company-bearing window title sanitized in the window manager — switchers and enumeration read generic labels, so the session's navigation doesn't narrate the business.
Shield the session. Billing, investor, customer, and internal notifications held during contractor calls — the churn alert never renders in front of the marketing agency.
A routine per contractor. Each recurring engagement fires its own configuration: protection that matches the contract's scope, including the session the founder takes from an airport.
Live preview at session start. The preview pane confirms the contractor's view. Engagement-scoped visibility, verified, is the difference between onboarding a vendor and disclosing the company.
The Honest Limitation
Screen enforcement complements — never replaces — vendor governance. NDAs, scoped tool access, and data-processing agreements remain the foundation; a contractor with legitimate analytics access can note your numbers regardless of what's cloaked. Architecture makes the accidental exposures impossible; contracts govern the deliberate ones. The tool is the fence; the agreement is the law.
The Bottom Line
Every contractor call is your company viewed through one screen by someone outside it. Make the screen enforce the engagement's scope: out-of-scope surfaces cloaked, titles masked, banners held, routine per contractor, preview at start. Give them everything they need to do the work — and nothing they didn't.
NoCapture provides OS-level window cloaking, title masking, and notification shielding for Windows. Free for two windows. Because "being careful" isn't a strategy.
