Public Key Infrastructure Market Growth Drivers and Challenges:
Growth Drivers
- Integration of cloud computing - Small and medium-sized enterprises have been helped to gain easier access to powerful technologies at a lower cost through cloud computing and applications.
A cloud access security broker shadow IT solution discovers, interprets, and secures cloud services to support shadow IT operations in enterprises. Security brokers for cloud access are an effective way of improving data security controls in organizations.
For example, in April 2022, Symantec, a company specializing in data-focused hybrid security solutions, combined its Data Loss Prevention (DLP) solution with CloudSOC, a cloud access security broker, to develop a comprehensive enterprise DLP solution. This solution encompasses shadow IT integration, user authentication, tailored dashboards and reports, and secure web gateways and firewalls. - AI and machine learning in PKI security - Artificial intelligence and machine learning are revolutionizing cybersecurity by enhancing threat detection, risk analysis, and incident response capabilities. These technologies play an important role in ensuring the security and integrity of digital identities and transactions, within the framework of a public key infrastructure (PKI) market .
Challenges
- Complexities and implementation challenges - Significant resources are needed to implement a robust PKI system in terms of skilled personnel, infrastructure design, and ongoing maintenance.
The initial investment and operating costs can be too high for organizations, in particular smaller ones with low IT budgets and technical expertise. PKI is the use of complicated cryptographic protocols, certificate management, key lifecycle management, and integration with different systems and applications. - Regulatory compliance burdens are projected to hamper the PKI market growth in the upcoming period
- Interoperability issues are set to hinder the market growth in the forecast period
