Our website has a specific section on security which gives details of all the measures in place. See this note for more details about data security.
More particularly,....
Any data you enter into your Inform Direct account is protected with SSL Encryption Certificates (secure socket layer technology) issued by leading certificate authority Verisign. This ensures all data you enter is encrypted when it is transmitted to the Inform Direct data centre. All data is stored in a third party hosted UK data centre.
We are also shown on the Companies House website as a tested and authorised provider of CoSec and formation software.
