Blockchain in cybersecurity enhances data security and integrity by providing immutable, decentralized storage for sensitive information. It creates tamper-proof records, reducing the risk of data breaches and unauthorized access. By using blockchain, cybersecurity solutions offer a secure framework for identity verification, secure data sharing, and monitoring network activities. Blockchain’s transparency and encryption methods also play a key role in combating cyberattacks and maintaining privacy, making it a powerful tool for protecting digital assets.
