Encryption in transit protects data while it is being transferred between systems, clients and servers, or between data centers. Common protocols include TLS (Transport Layer Security) for web traffic, SSH for remote access, and VPN tunnels for site-to-site connectivity.
GDPR Article 32 requires appropriate technical measures including encryption. Encryption in transit is considered a fundamental security control and its absence for personal data transmission would likely be considered a failure to implement appropriate measures under most privacy regulations.

Data Encryption
Encryption transforms readable data into an unreadable format using cryptographic algorithms, protecting confidentiality by ensuring only authorized parties with the correct key can access the data.
Encryption at Rest
Encryption at rest protects stored data by encrypting it on disk, in databases, or in storage systems, ensuring data confidentiality even if storage media is physically compromised.
API Security
API security encompasses practices and technologies that protect application programming interfaces from unauthorized access and data exposure.
