Before you buy
Five questions for any security device
The same checks apply to a security key, an HSM or a write blocker. If a vendor cannot answer them, keep looking.
Threat model
Which attack does this device stop, and which ones are out of scope? Write it down before comparing products.
Certification scope
A certificate covers one module, one firmware version and one configuration. Check that yours matches the certified one.
Provenance
Buy from the manufacturer or an authorized channel, inspect packaging, and verify attestation or serials where possible.
Firmware lifecycle
Can it be updated, are updates signed, and how long is the support window? Non-updatable can be a feature or a liability.
Recovery path
Plan the spare, the backup and the documented recovery procedure on day one, not after the first lost device.

How we write about hardware
Vendor-neutral
No affiliate links, no sponsored placements and no invented prices. Products are named only when they illustrate a category.
Threat model first
Every device is described by what it defends against, what it cannot defend against and what it costs you in operations.
Defensive by design
Lab content is about assessing and hardening devices you own or are authorized to test, never about attacking other people's.
