Check your product yourself

Three tools. All run in your browser, and nothing you enter is sent anywhere.

• TCB check. Seven questions. You get the list of everything your product's security rests on: what you take on trust, what you can prove, what is out.
• TCB definition tool. An ordinary computer trusts more than twenty parts. Pick a technology and see what measured boot, enclaves and confidential VMs change.
• Reattestable self-check. Ten questions. You get a grade from A to D for how well your product proves itself again after it changes.

What to read with them

• How each platform attests
