Your laptop is stolen … and BitLocker turns out not to be enough. Now what?

 

Picture this:

✅ Your laptop is neatly encrypted with BitLocker to protect data in case of theft. ✅ You trust your IT partner’s security. ❌ But an attacker still manages to read your drive, without a password or recovery code….

You can do that with an attack: a clever way to bypass BitLocker without a screwdriver or special hardware.

And the annoying thing is: many SMEs think they are well protected, even though there are risks that you don’t immediately think about.

Recognizable security pain

Which ones do you recognize?

🔹 I trust BitLocker, but doubt it’s enough
You know your laptop is encrypted, but somewhere it keeps gnawing: is it really secure enough in case of theft?

🔹 I worry about theft of laptops
A laptop is gone in a flash … and then what about all the data on it?

🔹 I don’t know about our settings
BitLocker, Secure Boot, UEFI … it sounds good, but is it set right?

🔹 I just want it to be secure, without fuss
You don’t want to need detailed IT knowledge. Just: it has to work and be secure.

 


Why BitLocker isn’t always enough

BitLocker is a good step, but it is not sacrosanct. There are ways to circumvent encryption with physical access if settings are not correct, or if there are no additional measures such as proper BIOS/UEFI lock, TPM configuration and policies that enforce that devices remain locked.

Many SMEs trust that “it’s taken care of,” but don’t know exactly how it’s set up. And that makes you vulnerable.


How to do it smarter, without the hassle

You don’t have to become an expert to get this right:

✅ Get checked that BitLocker is set up correctly (and fully active).
✅ Arrange a policy for device management and locking.
✅ Turn on monitoring and automatic notifications in case of anomalies.
✅ Consider additional measures such as MFA, secure cloud backups and device management.

This way you can be sure that your laptop theft does not mean instant data breach.
