Data Security

    Data security is the practice of protecting data from unauthorized access, use, or disclosure. Learn about data security and how to protect against cyber threats.

    What is Data Security?

    Data security is the protection of digital data, such as information in a database, from destructive forces and from the unwanted actions of unauthorized users, such as via cyberattack or a data breach.

    Importance of Data Security

    As data volumes within organizations grow, so must secure policies and procedures. In addition, as the complexity of data storage environments and the data itself continues to grow, so must data security.

    Organizations should strongly consider:

    • Obligation: Organizations that store user data have a legal and ethical responsibility to protect that data. When an organization stores personal details and payment information, it also must accept the task of safeguarding that data. Organizations must also communicate their security practices very clearly.
    • Reputation: When a data breach occurs, it can negatively impact the organization’s reputation. Organizations should develop clear and concise procedures for data security.
    • Resources: Data breaches cost organization’s time and money. Investing in effective data security practices as early as possible can save resources by avoiding the labor and monetary costs of recovering compromised data.

    Data Security and GDPR Rrequirements

    When the European Union General Data Protection Regulation (GDPR) took effect in May 2018, data security became a primary concern. Since then, the EU's new data privacy regulations require companies to get explicit consent from EU residents before collecting, storing and using their personal data. EU residents have the right to request from any organization what data about them is being stored and used. And residents can withdraw their consent at any time, obligating organizations to erase their data. The regulations also feature extensive directives concerning data security standards.

    Many organizations had to overhaul business processes and technology to ensure data security and compliance with GDPR regulations.

    When GDPR rolled out in May 2018, companies started looking for innovative solutions that would ensure data security while minimizing the cost and administrative burden of complying with GDPR regulations.

    GDPR Compliance Requires Email Data Security

    Since GDPR took effect, compliance changed the way many organizations manage email. And with cyber attacks heavily targeting email systems, ensuring email data security is growing more difficult by the day. Organizations are still faced with the need to adopt technology that allows for granular archiving, search, retrieval and deletion of emails, in order to comply with user requests.
