NEW Smart card & PKI token support with X.509 certificates

Your certificate is the key.
Boot BitLocker with your smart card.

Secure Disk for BitLocker uses the X.509 certificate on your smart card or PKI token like an extra BitLocker protector: before Windows starts, the user inserts the smart card or plugs in the PKI token, enters the PIN, and the BitLocker-protected Windows PC boots. It works with almost any PKCS#11 middleware, preinstalled or uploaded in the central console.

  • Works like an extra BitLocker protector
  • Multi-factor: certificate + PIN
  • Smart cards and PKI tokens
  • Almost any PKCS#11 middleware
  • From USD 50 per endpoint

What makes it unique

Not a data partition unlock. Our certificate protector for booting Windows.

Secure Disk for BitLocker does not just mount a partition with an X.509 certificate. It lets the certificate on the smart card or PKI token act like an extra BitLocker protector, so the user can boot a BitLocker-protected Windows PC with it.

Not this

Mounting a data partition with an X.509 certificate

The smart card unlock built into Windows BitLocker only works for fixed and removable data drives. It unlocks them with a certificate once Windows is already running, and it cannot unlock the operating system drive at startup.

This

Booting the BitLocker-protected Windows PC with your certificate

Secure Disk for BitLocker uses the X.509 certificate on the smart card or PKI token as an additional way to unlock the Windows system drive, before Windows starts. The private key never leaves the chip and is protected by the PIN.

PKCS#11 middleware

Bring your smart card, keep your middleware

Secure Disk for BitLocker talks to smart cards and PKI tokens through standard PKCS#11 middleware. Common middleware is preinstalled. If you use a different one, upload it in the central console and Secure Disk for BitLocker rolls it out to your clients.

Preinstalled

Widely used PKCS#11 middleware ships with Secure Disk for BitLocker, so many smart cards and PKI tokens work out of the box.

Upload your own

Using a specific card or token vendor? Upload its PKCS#11 middleware in the central console, no client-side installation needed.

Rolled out centrally

The central console distributes the middleware to the pre-boot environment of every client, ready at the next boot.

Secure Disk pre-boot

BitLocker unlocked

Windows starts, single sign-on to the desktop

How it works

From power button to desktop in four steps

1

Power on

Secure Disk for BitLocker starts its pre-boot authentication before Windows loads. The BitLocker volume stays locked.

2

Insert card or token

The user inserts the smart card into the reader or plugs in the PKI token.

3

Enter the PIN

The PIN unlocks the private key on the chip. Secure Disk for BitLocker verifies the X.509 certificate and that the user is authorised to boot this device.

4

BitLocker unlocks

The drive is decrypted and Windows starts. With single sign-on, the user continues straight to the desktop.

One badge for building access, Windows logon and now BitLocker boot, with the certificate from your corporate CA.

Symbolic X.509 certificate smart card
Smart card

PKI certificate card

A dedicated smart card carrying the user's X.509 certificate and private key for logon, signing and encryption.

Symbolic dual-interface smart card
Smart card

Dual-interface card

Chip for contact readers plus a contactless interface for doors and printers, with the same certificate on board.

Symbolic eID card with qualified certificate

eID and signature cards

Government or professional ID cards with a certificate, where the issuer provides a PKCS#11 middleware.

Symbolic Thales SafeNet eToken
PKI token · USB

PKI token, e.g. Thales SafeNet eToken

A USB token instead of card and reader: the certificate and private key sit on the token, protected by the token PIN.

PKCS#11
Your choice

Your card, your middleware

Using another card or token? If it comes with PKCS#11 middleware, upload it in the central console. Ask us about compatibility.

Banking, finance and insurance

Certificate-based multi-factor authentication that meets regulatory expectations.

Healthcare

Health professional cards and badges protect patient data from the very first boot.

Defence and critical infrastructure

Hardware-bound certificates and PINs before boot for high security obligations.

Law firms and notaries

FAQ

Frequently asked questions

Is this the same as BitLocker's own smart card unlock?
No. Windows BitLocker can unlock data partitions with a smart card certificate once Windows is running, but not the operating system drive. Secure Disk for BitLocker uses the X.509 certificate like an extra BitLocker protector at pre-boot, so the user can boot the BitLocker-protected Windows PC with it. This is a unique feature of Secure Disk for BitLocker.
Which smart cards, PKI tokens and middleware are supported?
Almost any smart card or PKI token with an X.509 certificate and a PKCS#11 middleware. Common middleware is preinstalled; other middleware can be uploaded in the central console. PIV cards are also covered by our dedicated PIV support. Contact us to check your card, token or reader.
Can we use the certificates from our existing PKI?
Yes. Secure Disk for BitLocker works with the user certificates your organisation already issues, for example from your corporate certificate authority. There is no need for a separate PKI just for BitLocker.
What happens if a user forgets the PIN or loses the card?
Secure Disk for BitLocker includes helpdesk functions that let IT restore access securely, without exposing the BitLocker recovery key to the user. A replacement card or token with a new certificate can be assigned to the user.
Do I need a TPM?
Yes, starting with Secure Disk for BitLocker 8 and Windows 11 a TPM 2.0 chip is required to run BitLocker. This is a great security enhancement to BitLocker and prevents brute-force attacks.
