Public Key Infrastructure (PKI) Market Trends

Growing demand for secure communication driving the market growth

Public key Infrastructure (PKI) provides a secure way to transmit data and protect against cyber threats. With the increasing use of digital communication channels, such as email, messaging apps, and online transactions, the demand for PKI is growing rapidly. It enables secure communication by using public and private key cryptography. The sender of a message uses the recipient's public key to encrypt the message, which can only be decrypted using the recipient's private key. This ensures that the message is not intercepted or read by unauthorized parties.

Moreover, PKI helps to verify the identity of the communicating parties. When a message is encrypted using a public key, it can only be decrypted using the corresponding private key. This assures that the message comes from the intended sender and has not been altered in transit. Therefore, the growing demand for secure communication due to increasing cyber threats, data breaches, and identity theft drives the demand for PKI. Thus, driving the public key infrastructure (PKI) market revenue.

As more businesses move their data and applications to the cloud, the need for secure communication and

data protection

is increasing. PKI provides a way to secure cloud-based data and applications using encryption and digital certificates. It helps to secure cloud-based services by providing authentication and authorization mechanisms. It enables users to securely access cloud-based resources by verifying their identity using digital certificates. This make sure that only authorized users can access sensitive applications and data.

Moreover, PKI helps to protect cloud-based data by encrypting it using public and private key cryptography. This safeguards that the data is not intercepted or read by unauthorized parties. PKI also helps to protect against man-in-the-middle attacks by ensuring that the communication between cloud-based services and users is secure and authenticated. Therefore, the increasing adoption of cloud-based services is driving the demand for PKI as businesses need to confirm the security of their applications and data in the cloud.

Public Key Infrastructure (PKI) Market Segment Insights

Public Key Infrastructure (PKI) Solution Insights

Based on the solution, the public key infrastructure (PKI) market segmentation includes PIN authentication, enrollment services, inventory of digital identities, secure roaming, self-recovery, and self-registration. The enrollment services public key infrastructure (PKI) segment dominated the market. Enrollment services are essential for any PKI implementation as they provide the foundation for secure communication and data protection. Without enrollment services, verifying the identity of users and devices and ensuring that only authorized parties have access to sensitive resources would be difficult. The dominance of the enrollment services segment is anticipated to continue as the demand for secure communication and data protection grows. However, other segments, such as inventory of digital identities and self-registration, are also expected to grow as digital identities become more widespread and organizations look for ways to streamline enrollment.

Public Key Infrastructure (PKI) Deployment Insights

Based on Deployment, the Public Key Infrastructure (PKI) market segmentation includes cloud-based and on-premise. The on-premise segment dominated the market. This is because On-premise PKI deployment offers several benefits, including greater control over the security of the PKI infrastructure, the ability to customize the infrastructure to meet specific business needs, and the ability to integrate the PKI infrastructure with existing IT systems. However, there has been a rising trend towards cloud-based PKI deployment in recent years. Cloud-based PKI deployment involves hosting the PKI infrastructure on a third-party cloud provider's servers, which can offer scalability, cost-effectiveness, and ease of management.
