In our increasingly digital world, cybersecurity has become one of the most critical concerns for individuals, businesses, and governments alike. With the number of cyber threats constantly on the rise, organizations must continuously seek new and innovative ways to protect their assets, data, and reputation.

The public key is freely shared with others, while the private key is kept confidential.
One of the key features of PKI is its ability to provide secure and authenticated communication.

By using these certificates, entities can establish secure connections, known as SSLVPN Tunnel: A secure connection between two or more devices .../TLS connections, over the internet. These connections encrypt the data being transmitted, ensuring that it remains confidential and cannot be intercepted by malicious actors.

This helps to prevent man-in-the-middle attacks, where an attacker intercepts and alters the communication between two entities.
Another critical aspect of PKI is its role in authentication. When a user or device presents a digital certificate to establish a connection, the receiving party can verify the certificate’s authenticity by checking its digital signature against the CA’s public key. This not only ensures the identity of the communicating entity but also provides a level of trust in the authenticity of the information being exchanged. PKI can be used for various authentication purposes, such as secure logins, digital signatures, and secure email.

With the increasing popularity of e-commerce and online banking, secure payment solutions have become a priority for businesses and customers alike. PKI enables the use of digital certificates to secure online transactions, ensuring that sensitive information, such as credit card details, remains confidential and protected from unauthorized access.
