Keep your data safe!

Recently the activity of cybercriminals has been more visible by trying to fraud customers on various websites. Therefore, we would like to ask you to be especially wary when completing a payment.

A usual activity of cybercriminals is attaching a file that imitates an invoice or asking for a payment with the bank connection and account number being changed to the criminals’ bank account.

To prevent being a victim of a cybercrime we would like to remind you about the following information and procedures at Grena Ltd.


1. Check the bank

Grena Ltd. has a bank account solely in the HSBC Bank in the United Kingdom.

2. E-mail Signature

Every e-mail you receive from us should be secured with a digital signature.

3. PFD digital Signature

Payment documents are being sent as a .pdf file and contain a digital signature that you can verify.


4. Verification by call

We suggest you check and confirm every invoice you receive before paying by calling our office in Nottingham using the phone numbers provided on our website: +44 115 9704 800.

We hope this short instruction will help you keep your personal and confidential information safe as well as be suspicious of unexpected messages containing payment documents.
