Why should a GDPR Audit be conducted​? 

Conducting a GDPR Audit is crucial for organisations to ensure they adhere to the requirements. The following reasons highlight the importance of conducting these audits regularly:  

Benefits of a GDPR Audit

a) Compliance verification: GDPR has established a comprehensive set of rules and regulations regarding the processing of Personal data. By conducting audits, organisations can assess their compliance with the GDPR requirements and identify any areas of non-compliance. This enables them to take corrective measures and align their data processing activities with GDPR’s standards, reducing the risk of penalties and legal consequences.  

b) Identifying risks: The auditing process allows organisations to evaluate their Data Protection practices and identify system vulnerabilities or weaknesses. By understanding their vulnerabilities, organisations can implement the required security practices to protect Personal data from unauthorised access, loss, or disclosure. This proactive approach helps prevent potential data breaches and safeguards the privacy rights of individuals.   

c) Protecting privacy rights: Conducting regular audits ensures that organisations are actively working towards protecting individuals' fundamental privacy rights by implementing appropriate measures to safeguard Personal data. Organisations can build trust with their customers, employees, and stakeholders via demonstrating a commitment to data privacy.    

d) Enhanced Data Protection: Through audits, organisations can assess the effectiveness of their data security measures, including encryption, access controls, and incident response plans. Identifying gaps or weaknesses in data security allows organisations to strengthen their security infrastructure and protect Personal data from unauthorised or unlawful processing.  

e) Building trust: In an era where data breaches and privacy scandals dominate headlines, organisations prioritising Data Protection and privacy gain a competitive advantage. Regular audits showcase an organisation's commitment to data privacy and security, helping build trust among customers, partners, and stakeholders. By maintaining a solid reputation in terms of Data Protection, organisations can attract and retain customers who value their privacy.  

f) Avoiding penalties: Non-compliance with GDPR can result in significant fines and penalties. By conducting audits, organisations can identify and rectify non-compliance issues before they lead to legal consequences. This proactive approach reduces the risk of penalties and ensures that enterprises operate within the legal boundaries of Data Protection regulations.

Basic terminologies in GDPR  

Personal data, Sensitive Personal data, Anonymous data, Pseudonymous data, Data processing, and Controller are some basic GDPR terms you need to understand. Here are their definitions and associated abbreviations: 

a) Personal data: Any information that can identify a living person is considered Personal data. This can be a combination of different pieces of information that can single out a specific person. 

b) Sensitive Personal data: A special Personal data requiring extra protection. Generally, organisations need stronger reasons to process Sensitive Personal data than they do for regular Personal data. 

c) Anonymous data: Data sets that are modified so that no one can recognise any person(s) (directly or indirectly) from them by any means or by anyone. Ensuring that individuals cannot be identified is a technically difficult process. 

d) Pseudonymous data: Data that is altered by using a reference number or other identifier to replace names or other identifiers that are easily linked to individuals. 

e) Controller: The legal person, agency, public authority, or other organisation that decides the purposes and means of Personal data processing, alone or with others. 

Reasons to Conduct GDPR Audit

It also gives individuals the right to data portability, the right to be informed, and not to be subject to automated decision-making or profiling. 

b) It requires organisations that process Personal data to comply with certain principles and obligations, such as lawfulness, fairness, transparency, accuracy, security, and accountability. It also requires organisations to obtain valid consent from individuals, conduct Data Protection impact assessments, appoint Data Protection officers to study data breaches, and cooperate with supervisory authorities. 

c) It harmonises the Data Protection laws across the EU and ensures a high level of Data Protection standards for businesses. It also provides a single set of rules and a single market for data, which can reduce costs and increase efficiency for organisations. It also facilitates the free flow of data within the EU and with third world countries with adequate Data Protection standards.
