Security hardware, chosen like an engineer.

A field guide to the devices that hold your keys, prove your boot chain, isolate your lab and preserve evidence, with the selection criteria that matter before you buy.

The security hardware map

Eight areas, from the key on your keyring to the probe on your bench. Each one explains what the device protects, what it does not, and how to pick one.

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.

  1. Threat model

    Which attack does this device stop, and which ones are out of scope? Write it down before comparing products.

  2. Certification scope

    A certificate covers one module, one firmware version and one configuration. Check that yours matches the certified one.

  3. Provenance

    Buy from the manufacturer or an authorized channel, inspect packaging, and verify attestation or serials where possible.

  4. 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.

  5. Recovery path

    Plan the spare, the backup and the documented recovery procedure on day one, not after the first lost device.

Editorial line

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.
