As to all of us in IT industry, security is also very important to us.
PAT Client is the one collecting all the data at customer site and sensitive information never leaves the premises and can not be accessed without permissions on the system. All personal, user connected, data is encrypted and can be viewed through PAT Client web interface only.
Data transmitted to PAT ecosystem, no matter if we talk about PAT Cloud or PAT On-premise, is also encrypted and upon retrieval decrypted at the endpoint for processing purposes. Once data has been processed, it is encrypted once again and stored on your system like that.
PAT Client, PAT Cloud and PAT On-Premise are all highly secure solutions and as such GDPR compliant.
