Encryption is the process of converting readable data (plaintext) into an unreadable format (ciphertext) using mathematical algorithms and cryptographic keys, ensuring that only authorized parties with the correct decryption key can access the original information. Modern encryption protects data both in transit (during transmission) and at rest (in storage), providing essential security for emails, files, databases, and communications against unauthorized access, interception, and cyber theft.
For UK businesses, encryption is fundamental to GDPR compliance and data protection obligations, as it significantly reduces breach impact by rendering stolen data useless without decryption keys. Implementation across devices, cloud storage, email systems, and backups protects sensitive customer information, financial data, and intellectual property whilst maintaining business confidentiality. Encryption enables secure remote work, protects against ransomware, and demonstrates due diligence in data security to regulators and customers.
