The key issues to consider when reviewing the storage of and access to personal data on computers and networks. At Hart Shaw, we can provide you with assistance or any additional information required.
Many businesses are now completely reliant on the data stored on their Network Servers, PCs, laptops, mobile devices and cloud service providers or internet service providers. Some of this data is likely to contain either personal information and/or confidential company information.
