Screen Privacy for Management Consultants

Monday morning, 6:15am, you're at gate B22 at LGA with three coffees of regret and the slides for the executive committee presentation due at noon. The deck has the client logo, the client's competitors named, and the recommendation that 1,800 roles will be impacted in Q3. The person sitting next to you, hand luggage tucked between their feet, leans over to charge their phone and gets a perfect read of slide 9.

Consulting is screen exposure as a lifestyle. You work where you can, which is rarely where you should.

What's on your screen

A typical consultant's open files in any given week:

• Client confidential decks, often with the client name in the title
• Market data under NDA, including data room contents from M&A diligence
• Competitive intelligence assembled from primary research
• Working models with assumptions that would embarrass everyone if seen
• Billable hours and rate cards, which the client is never supposed to see
• Interview notes from client employees, often candid
• Org charts with names, sometimes with retention risk flags
• Engagement letters and SOWs with fees specified
• Internal partner emails about the engagement, including candid assessments

The interview notes are the most delicate. Client employees often speak candidly to consultants in interviews, and those notes, glimpsed by another client employee in the elevator, can blow up an engagement.

Where shoulder surfing happens for consultants

Airports, every airport, every gate. Airline lounges. Hotel lobbies, especially the workspace tables that hotels have added since 2020. The client cafeteria, where you're often eating with your laptop open between sessions. The client's open-plan office where they've parked you in a hot desk. Co-working spaces in cities you fly to weekly. The Uber back to the hotel. The hotel bar at 9pm finishing a deck.

The client cafeteria case is especially bad. The other people in the cafeteria are exactly the people who shouldn't see the slides. They're employees of the company you're recommending changes to.

The unique risks

Consulting has a layered exposure that's professional, contractual, and reputational.

NDA violations: most engagement letters include broad confidentiality clauses. Casual visual disclosure is still a breach, and savvy clients have terminated engagements over it.

Malpractice exposure: top-tier firms carry E&O policies that exclude intentional breaches. Negligent ones, including failure to safeguard, get scrutinized.

Firm reputation: McKinsey-style firms enforce strict client confidentiality precisely because their entire business model is trust. A public screen-read disclosure becomes a firm-level reputation hit.

Competitive intelligence sourcing: if you collected market data through interviews under attribution restrictions, a public glimpse of those notes can blow your sources.

Insider trading second-order risk: if your client work involves a publicly traded company and material non-public information leaks via your screen, the firm has SEC exposure even if you weren't the source of the leak.

Consultants are paid to know things. They are paid more, in the long run, for being trusted not to share them in ways they shouldn't.

Practical methods

The consulting lifestyle demands methods that survive constant travel.

Privacy filter installed permanently. The 60-degree narrow filters are standard issue at most top firms, and there's a reason.

Generic-name your files. The client is "ProjectAlpha" in the file name and folder structure. The logo on the deck is the firm logo, not the client logo, until you're inside the client's building.

Use a smaller travel laptop posture, a 13-inch screen at the airport, not the 16-inch. The smaller screen at sharper angle is harder to read passively.

Lock the screen for every airport bathroom run, every coffee refill, every step away. Cmd+Ctrl+Q.

No client work in airline middle seats, ever. Read industry news, write expense reports, do anything else.

Different browser profile per engagement. A glance at your tabs shouldn't reveal three client names.

Don't open the engagement deck in the client cafeteria. Use the project room, the bathroom, or wait.

Where camera-based detection fits in

For a consultant, the value is the airport, the lobby, the cafeteria. Peeker runs locally on the Mac, watches for faces behind you using the webcam, and shows a small preview in the corner. Nothing leaves the device. No video is recorded. It's a quiet awareness layer for the moments when you got absorbed in the model and forgot the gate area filled up.

It is not approved as a substitute for the firm's information security program. It's a personal control on top of that program.

FAQ for consultants

Will Peeker satisfy our firm's IT review? The app is signed, notarized, and uses standard macOS camera permissions. It processes camera frames locally and never writes to disk or transmits data. Most top-tier firm IT teams can approve it on those properties.

Does it work with the firm's MDM and DLP stack? It doesn't interact with clipboard, network, or document content. It coexists with DLP solutions like Symantec or Microsoft Purview without conflict.

I'm in the client cafeteria. Does it draw attention to my laptop having a camera on? The indicator light is on while it runs. If that draws attention, disable it during the cafeteria session with the menu bar toggle.

Wrap

Consulting clients pay for judgment and trust. The least the consultant can do is treat the deck like the confidential document it is, regardless of where it gets opened. Peeker is $5/year.
