Account Manager, consulting firm, Paris — Mac user
Hi,
I wanted to write to you because I've been using Shield for about a month now and I think you should hear this from an actual user.
I'm an account manager at a consulting firm in Paris. I spend my days in conference rooms, client offices, open workspaces. My MacBook has everything on it: proposals, contracts, financial projections, client data. And for years I had this stupid problem that I never talked about with anyone.
Every time I left my laptop to get a coffee or take a call, I had to decide: do I lock the screen or not? It sounds like nothing, but locking your laptop in front of a client sends a signal. It says "I don't trust you." In my job, trust is everything. So most of the time I just didn't lock it.
A few weeks before I found Shield, I was in a client meeting and stepped out to take a quick call. When I came back, someone on the client side said something like "oh, I noticed you're working on something similar for [company name]." Nothing aggressive, just a casual comment. But I had a tab open with work for one of their competitors. It wasn't a disaster, nobody complained, but it made me realize how often my screen is just sitting there, open, with things on it that other people shouldn't see.
A colleague from IT mentioned Shield to me. I installed it the same day.
The first time I tested it I just stood up and walked to the other side of the room. By the time I turned around, the screen was locked. I sat back down and it unlocked before I even reached for the keyboard. I remember thinking: this is how it should have always worked.
But the thing that really changed things for me is Shoulder Guard. Even when I'm sitting right there, if someone leans over to look at my screen, it blurs. No confrontation, no awkward gesture, nothing. It just happens. Nobody even notices it's running.
That's the difference. Locking your screen says "I don't trust you." Shield says nothing. It just protects. Silently.
After a month, I don't think about screen privacy anymore. I don't calculate whether to lock or not. Two people on my team installed it on their own Macs after they saw it working during a meeting when I stepped out.
Three things I'd mention specifically:
1. It's invisible. No app window, no notifications, no icon flashing. Clients never ask "what's that?" because there's nothing to see.
2. It's instant. I used to have a 5-minute screen timeout. Five minutes is an eternity when you have a proposal open in a room full of people.
3. It's not personal. When the screen blurs because someone glances over, it's not me making a choice to hide something. It's the software. There's no social friction because there's no human decision.
If you work with people, if you carry sensitive information on your laptop, if you've ever felt that awkward moment of deciding whether to lock your screen in front of someone: get Shield. It's not expensive, it's not complicated, and it solves a problem most people don't even realize they have.

Editor's note
We received Julie's email on April 14, 2026 and published it with her permission. Her main point is one we hear often: manually locking your screen in front of a client feels unprofessional and signals a lack of trust. Most people just skip it. Shield locks and unlocks automatically, so there's nothing awkward to do or explain.
