"Smart Strategies, Giving Speed to your Growth Trajectory"
The global public key infrastructure market size was valued at USD 5.09 billion in 2023 and is projected to grow from USD 5.84 billion in 2024 to USD 24.37 billion by 2032, exhibiting a CAGR of 19.6% during the forecast period.
A Public Key Infrastructure (PKI) is a set of software, hardware, processes, policies, and procedures required to manage, generate, distribute, use, and store digital certificates and public-keys. The PKI methodologies are designed to protect the exchange of messages and transactions among devices and systems within Internet of Things (IoT). PKI facilitates secure identification and verification of devices, as well as the encryption and decryption of data shared among them via digital certificates, public & private keys, and additional security features.
PKI is being increasingly relied upon to support a wide range of users, applications, and devices within intricate IT landscapes. It can be employed to verify and secure data sent from a smart home gadget to a mobile application or to confirm the identity of a medical device prior to granting access to patient information. Technological advancements have made it possible to use digital signatures, certificates, and encryption, which are driving the expansion of the global PKI market. Furthermore, the growing demand for secure data exchange in sectors, such as banking, finance, and healthcare is accelerating the public key infrastructure PKI market growth. The increasing awareness regarding data security is also expected to fuel market expansion.
The onset of the COVID-19 pandemic compelled governments across the globe to implement lockdowns to ensure public safety. The growing popularity of smartphones and increase in internet access, especially during the pandemic, increased the usage of PKI solutions. These changing trends and disrupted IT systems made businesses more susceptible to cyberattacks and data leaks, which in turn, boosted the demand for PKI solutions. The risk of data breaches, especially in terms of security and access protocols for managing cloud environments while working remotely, escalated with the introduction of new devices. The need for security technologies surged as more people worked from home. This was the key factor which propelled the demand for PKI solutions during the pandemic.
AI-Integrated Public Key Infrastructure Solutions to Boost Operational Efficiency of Various Companies
Incorporating Artificial Intelligence (AI) into PKI solutions allows companies to make the most of resources, such as predictive analytics and machine learning algorithms to improve their security and identify vulnerabilities and misconfigurations. In certain instances, AI can detect vulnerabilities and suggest corrective actions. This approach positions digital infrastructure to defend itself against new threats proactively.
AI simplifies the processes for issuing, renewing, and revoking certificates, minimizing the delays and errors that come with manual operations. However, according to research, only 37% of companies are currently using a PKI solution to boost AI and gen-AI content.
Similarly, AI optimizes cryptographic functions, such as key generation and encryption, thereby enhancing their security. Integrating AI into PKI enhances operational efficiency and reduces human error, which is considered a major factor in security breaches. Many companies need help to afford PKI experts. Hence, the incorporation of artificial intelligence can help them manage PKI more effectively. Furthermore, AI offers insights into how certificates are used, identifying potential security risks. These are the factors that will boost the usage of AI-integrated PKI solutions to improve the operational efficiency of the organizations present across different industries.
Integration of IoT Devices with Public Key Infrastructure for Data Security to Fuel PKI Market Growth
The integration of IoT devices with PKI solutions plays a critical role in securing communication, authentication, data security, and integrity and rebooting the encryption process. PKI-based authentication and identity verification protect IoT ecosystems against malicious cyberattacks and data breach activities that aim to disrupt data integrity and confidentiality. For instance,
PKI also enables safe communication among IoT devices and the backend IT infrastructure of organizations, which leads to forming encrypted connections through digital certificates to protect sensitive data from unauthorized access. PKI is used in IoT for various applications, including secure firmware updates, protecting data exchange between IoT devices, and safe remote access. It also helps in managing permissions and access control by using certificates and defining and enforcing policies on what each device or user is allowed to do. Through this, the PKI can be used to authenticate and validate the firmware updates, which helps maintain the integrity of the data.
Thus, the integration of IoT devices with PKI to enhance data integrity and security is the key factor that will drive the growth of the market.

Adoption of Cloud-based Services to Secure Business Applications from Cyberattacks to Drive PKI Market Growth
Public key infrastructure provides a secure way to transmit data and protect it against cyber threats. With the increasing use of digital communication channels, such as emails, messaging apps, and online transactions, the demand for PKI is growing rapidly. It enables secure communication by using public and private key cryptography.
Various businesses are moving their data and applications to the cloud, and 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 protect 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. It makes sure that only authorized users can access sensitive applications and data.
Moreover, PKI safeguards cloud-based data by encrypting it using private and public key cryptography. It helps protect the data from unauthorized access and a large number of cyber threats to ensure secure and authenticated communication among users and cloud-based services. 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.
Complex Implementation of PKI Solutions to Hamper Market Growth
Integrating PKI into the existing IT infrastructure and applications can be complex and time-consuming, requiring specialized knowledge and expertise. Additionally, managing and maintaining PKI systems can be demanding, involving activities, such as certificate lifecycle management and key distribution.
Expiration of certificate validity, integration of several connected devices, and implementation of new standards have made it increasingly challenging for SecOps and NetOps teams to keep their certificate infrastructures in perfect working order. Thus, implementing PKI solutions across various businesses is comparatively complex, which disrupts the productivity of businesses worldwide. Hence, the complex nature of PKI will hinder the growth of the public key infrastructure market over the forecast period.
Adoption of Cloud-based PKI to Rise to Improve Organization's Performance
By deployment, the PKI market is divided into on-premises and cloud.
The cloud segment is projected to record the highest CAGR over the forecast period. The demand for cloud-based PKI solutions in small and medium enterprises is high compared to on-premises solutions due to complexity and pricing issues. As cloud solutions are easily accessible, scalable, and cost-effective, the demand for cloud-based PKI solutions in SMEs is high compared to that of on-premises.
Similarly, the cloud environment enables enterprises with limited infrastructure and expertise to deliver comprehensive data security solutions that aim to deliver cloud-based services to their consumers across the globe. Thus, the demand for cloud-based solutions is high.
