随着越来越多的组织在日益数位化的生态系统中优先考虑安全通讯、身分管理和资料完整性,全球公钥基础设施 (PKI) 市场持续快速成长。产业研究预测,该市场规模将在 2024 年达到 58.4 亿美元,2025 年成长至 67.6 亿美元,并在 2032 年达到 243.7 亿美元,预测期内复合年增长率 (CAGR) 高达 20.1%。北美地区在 2024 年占 39.73% 的市场占有率,凭藉先进的数位化水准和较高的网路安全普及率,继续保持领先地位。
公钥基础设施 (PKI) 透过实现加密、身分验证、凭证管理和安全电子通信,为数位安全奠定了基础。 PKI 系统整合了硬体、软体、策略和协议,管理公钥和私钥,以确保装置、应用程式和使用者之间安全的资料交换。随着物联网生态系统的扩展以及人工智慧技术在企业环境中的日益融合,PKI 解决方案对于保护数位信任至关重要。
2024 年 PKI 与数位信任报告(1,200 位受访者)指出,行动装置的使用(48%)、人工智慧整合(46%)以及物联网的普及(46%)正在推动各组织采用 PKI。这些因素显着推动了全球对可扩展、自动化和云端支援的 PKI 解决方案的需求。
人工智慧对 PKI 部署的影响
人工智慧 (AI) 正在改变 PKI 系统的部署和维护方式。 人工智慧透过增强证书生命週期管理、自动续期、识别错误配置和漏洞预测来强化组织安全。人工智慧洞察能够优化加密功能并减少人为错误,而人为错误是安全漏洞的主要驱动因素。儘管有这些优势,但目前只有 37% 的公司使用公钥基础设施 (PKI) 来支援人工智慧和生成式人工智慧,这表明在未来的企业架构中,整合人工智慧的 PKI 具有巨大的成长潜力。
市场趋势
物联网设备与 PKI 的整合是推动製造业、医疗保健、物流和智慧城市应用采用 PKI 的关键趋势。随着数十亿物联网设备透过网路通信,PKI 可确保安全身份验证、加密资料传输以及防止未经授权的存取。例如,DigiCert 于 2024 年 5 月发布了“设备信任管理器”,这是一款专为物联网设计的安全解决方案,可实现端对端加密和基于证书的设备身份验证。这些进步支援安全的韧体更新、设备权限管理和身份验证,使 PKI 成为物联网安全基础设施的关键组成部分。
成长因素
云端服务的快速普及正在推动公钥基础设施 (PKI) 市场的扩张。随着企业越来越依赖数位通讯、远端连接和云端託管应用程序,强大的加密和基于凭证的身份验证机制至关重要。 PKI 透过安全的身份验证、加密资料传输和云端安全工作流程来满足这些需求。
日益增长的网路威胁也在加速 PKI 的普及。到 2022 年,92% 的组织将遭受网路攻击,73% 的组织将面临严重的安全事件。这进一步推动了对强大的身分管理和信任框架的需求。 PKI 透过防止未经授权的存取、实现安全交易以及提供确保资料完整性的数位签章来保护云端资料。
限制因子
儘管 PKI 具有巨大的成长潜力,但其普及仍然十分复杂。组织面临着许多挑战,例如与现有基础设施整合、管理证书以及确保合规性。 证书过期、设备激增以及安全标准的快速演变,给安全营运团队带来了日益沉重的营运负担。这些挑战限制了缺乏必要专业知识的企业采用公钥基础设施 (PKI)。
由于云端部署具有易于存取、可扩展和成本效益等优点,因此预计其复合年增长率 (CAGR) 将最高,尤其对中小企业 (SME) 而言。同时,由于银行、金融和保险 (BFSI)、医疗保健和政府部门对资料管理有着严格的要求,本地部署的 PKI 在 2024 年仍将占主导地位。
按公司规模划分,由于安全需求不断增长且 IT 资源有限,预计中小企业 (SME) 的增长速度最快。 由于大型企业在数位身分框架方面投入巨资,预计它们将在 2024 年占最大市场占有率。
在应用领域,应用效能管理将推动成长,而网路和安全管理由于对加密通讯的需求不断增长,将在 2024 年保持最大市场占有率。
2024 年,IT 和通讯产业将占最大市场占有率,这主要得益于数位化、云端运算的普及以及大量资料的涌现。製造业、银行、金融服务和保险 (BFSI) 以及医疗保健行业预计也将因网路安全风险的上升而出现强劲需求。
预计到 2024 年,北美市场规模将达到 23.2 亿美元,这主要得益于主要公钥基础设施 (PKI) 供应商和成熟的 IT 基础架构。由于网路攻击的增加以及中国、印度、日本和澳洲云端运算的普及,预计亚太地区将实现最高的复合年增长率 (CAGR)。欧洲市场正经历缓慢但稳定的成长,这主要得益于监管合规措施的推动。 中东和非洲正在崛起成为成长速度第二快的地区,而南美洲则在数位转型计画的推动下,正在加速采用新技术。
The global public key infrastructure (PKI) market continues to expand rapidly as organizations worldwide prioritize secure communication, identity management, and data integrity across increasingly digital ecosystems. According to industry findings, the market was valued at USD 5.84 billion in 2024, is projected to rise to USD 6.76 billion in 2025, and is forecast to reach USD 24.37 billion by 2032, reflecting a robust CAGR of 20.1% during the forecast period. With 39.73% market share in 2024, North America remains the leading region, supported by advanced digitalization and high cybersecurity adoption rates.
PKI plays a foundational role in digital security by enabling encryption, authentication, certificate management, and secure electronic communication. PKI systems integrate hardware, software, policies, and protocols to manage public and private keys, ensuring safe data exchange across devices, applications, and users. As IoT ecosystems expand and AI technologies integrate into enterprise environments, PKI solutions are becoming indispensable for safeguarding digital trust.
A 2024 PKI & Digital Trust Report, surveying 1,200 respondents, confirmed rising PKI adoption driven by 48% mobile device usage, 46% AI integration, and 46% IoT deployment across organizations. These forces significantly elevate demand for scalable, automated, and cloud-compatible PKI solutions globally.
Impact of AI on PKI Adoption
Artificial Intelligence is reshaping how PKI systems are deployed and maintained. By enhancing certificate lifecycle management, automating renewals, identifying misconfigurations, and predicting vulnerabilities, AI strengthens organizational security. AI-driven insights also optimize encryption functions and mitigate human error-one of the leading factors behind security breaches. Despite these benefits, only 37% of companies currently use PKI to support AI and generative AI, highlighting vast growth potential for AI-integrated PKI deployments in future enterprise architectures.
Market Trends
The integration of IoT devices with PKI is a major trend driving adoption across manufacturing, healthcare, logistics, and smart city applications. As billions of IoT devices communicate across networks, PKI ensures secure authentication, encrypted data transmission, and protection from unauthorized access. For instance, in May 2024, DigiCert launched its "Device Trust Manager," an IoT-focused security solution that enables end-to-end encryption and certificate-based device authentication. These advancements support secure firmware updates, device permissions, and identity verification-making PKI a critical component of IoT security infrastructure.
Growth Drivers
The rapid adoption of cloud-based services is fueling PKI market expansion. Businesses increasingly rely on digital communications, remote connectivity, and cloud-hosted applications-necessitating strong encryption and certificate-based authentication mechanisms.
