There’s no single ’executive security’ product because there’s no single threat. Map the tool to the exposure: your logins, your screen, your device in a hostile place, your files at rest. Here’s the priority order for most people.

Where each one wins

Yubico YubiKey 5C NFC

The highest-leverage buy on the list. FIDO2 hardware makes your email and SSO un-phishable. Cheap, and the single biggest reduction in real-world risk. Buy two. Check the current Amazon price.

3M Gold Privacy Filter

The cheapest fix for the most common leak — someone reading your screen in a lounge or on a plane. Sharp side-angle blackout, keeps your head-on brightness. Check the current Amazon price.

Mission Darkness Dry Shield Faraday Laptop Bag

Specialist protection for travel to jurisdictions where a device in your bag can be located or attacked. Broad-band RF isolation with a maintained seal. Check the current Amazon price.

Kingston IronKey Vault Privacy 80 Encrypted SSD

Hardware-encrypted storage with an on-device PIN pad — for carrying sensitive files air-gapped from the laptop, safe if lost. Check the current Amazon price.

The call

Buy in this order: the YubiKey (everyone, now), then the 3M privacy filter if you ever work in public. Add the Mission Darkness Faraday bag only if your travel takes you somewhere you don’t trust the network, and the Kingston IronKey only if you routinely carry sensitive files outside managed systems.

Before you buy — quick answers

If I buy one thing?
The YubiKey. It closes the attack that actually gets executives — phishing — for about the price of a nice lunch.
Do these overlap?
No — each addresses a distinct exposure. That’s why the article ranks them by how many people actually face each threat.

Start with the YubiKey 5C NFC. It's the one nobody should skip.
