隨著越來越多的組織在日益數位化的生態系統中優先考慮安全通訊、身分管理和資料完整性,全球公鑰基礎設施 (PKI) 市場持續快速成長。產業研究預測,該市場規模將在 2024 年達到 58.4 億美元,2025 年成長至 67.6 億美元,並在 2032 年達到 243.7 億美元,預測期內複合年增長率 (CAGR) 高達 20.1%。北美地區在 2024 年佔 39.73% 的市場佔有率,憑藉先進的數位化水準和較高的網路安全普及率,繼續保持領先地位。
公鑰基礎設施 (PKI) 透過實現加密、身分驗證、憑證管理和安全電子通信,為數位安全奠定了基礎。 PKI 系統整合了硬體、軟體、策略和協議,管理公鑰和私鑰,以確保裝置、應用程式和使用者之間安全的資料交換。隨著物聯網生態系統的擴展以及人工智慧技術在企業環境中的日益融合,PKI 解決方案對於保護數位信任至關重要。
2024 年 PKI 與數位信任報告(1,200 位受訪者)指出,行動裝置的使用(48%)、人工智慧整合(46%)以及物聯網的普及(46%)正在推動各組織採用 PKI。這些因素顯著推動了全球對可擴展、自動化和雲端支援的 PKI 解決方案的需求。
人工智慧對 PKI 部署的影響
人工智慧 (AI) 正在改變 PKI 系統的部署和維護方式。 人工智慧透過增強證書生命週期管理、自動續期、識別錯誤配置和漏洞預測來強化組織安全。人工智慧洞察能夠優化加密功能並減少人為錯誤,而人為錯誤是安全漏洞的主要驅動因素。儘管有這些優勢,但目前只有 37% 的公司使用公鑰基礎設施 (PKI) 來支援人工智慧和生成式人工智慧,這表明在未來的企業架構中,整合人工智慧的 PKI 具有巨大的成長潛力。
市場趨勢
物聯網設備與 PKI 的整合是推動製造業、醫療保健、物流和智慧城市應用採用 PKI 的關鍵趨勢。隨著數十億物聯網設備透過網路通信,PKI 可確保安全身份驗證、加密資料傳輸以及防止未經授權的存取。例如,DigiCert 於 2024 年 5 月發布了“設備信任管理器”,這是一款專為物聯網設計的安全解決方案,可實現端對端加密和基於證書的設備身份驗證。這些進步支援安全的韌體更新、設備權限管理和身份驗證,使 PKI 成為物聯網安全基礎設施的關鍵組成部分。
成長因素
雲端服務的快速普及正在推動公鑰基礎設施 (PKI) 市場的擴張。隨著企業越來越依賴數位通訊、遠端連接和雲端託管應用程序,強大的加密和基於憑證的身份驗證機制至關重要。 PKI 透過安全的身份驗證、加密資料傳輸和雲端安全工作流程來滿足這些需求。
日益增長的網路威脅也在加速 PKI 的普及。到 2022 年,92% 的組織將遭受網路攻擊,73% 的組織將面臨嚴重的安全事件。這進一步推動了對強大的身分管理和信任框架的需求。 PKI 透過防止未經授權的存取、實現安全交易以及提供確保資料完整性的數位簽章來保護雲端資料。
限制因子
儘管 PKI 具有巨大的成長潛力,但其普及仍然十分複雜。組織面臨著許多挑戰,例如與現有基礎設施整合、管理證書以及確保合規性。 證書過期、設備激增以及安全標準的快速演變,給安全營運團隊帶來了日益沉重的營運負擔。這些挑戰限制了缺乏必要專業知識的企業採用公鑰基礎設施 (PKI)。
由於雲端部署具有易於存取、可擴展和成本效益等優點,因此預計其複合年增長率 (CAGR) 將最高,尤其對中小企業 (SME) 而言。同時,由於銀行、金融和保險 (BFSI)、醫療保健和政府部門對資料管理有著嚴格的要求,本地部署的 PKI 在 2024 年仍將佔主導地位。
按公司規模劃分,由於安全需求不斷增長且 IT 資源有限,預計中小企業 (SME) 的增長速度最快。 由於大型企業在數位身分框架方面投入巨資,預計它們將在 2024 年佔最大市場佔有率。
在應用領域,應用效能管理將推動成長,而網路和安全管理由於對加密通訊的需求不斷增長,將在 2024 年保持最大市場佔有率。
2024 年,IT 和通訊產業將佔最大市場佔有率,這主要得益於數位化、雲端運算的普及以及大量資料的湧現。製造業、銀行、金融服務和保險 (BFSI) 以及醫療保健行業預計也將因網路安全風險的上升而出現強勁需求。
預計到 2024 年,北美市場規模將達到 23.2 億美元,這主要得益於主要公鑰基礎設施 (PKI) 供應商和成熟的 IT 基礎架構。由於網路攻擊的增加以及中國、印度、日本和澳洲雲端運算的普及,預計亞太地區將實現最高的複合年增長率 (CAGR)。歐洲市場正經歷緩慢但穩定的成長,這主要得益於監管合規措施的推動。 中東和非洲正在崛起成為成長速度第二快的地區,而南美洲則在數位轉型計畫的推動下,正在加速採用新技術。
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. PKI addresses these needs through secure identity validation, encrypted data transmission, and cloud-compatible security workflows.
Growing cyber threats further accelerate adoption. In 2022, 92% of organizations experienced cyberattacks, while 73% faced severe incidents, reinforcing the need for strong identity management and trust frameworks. PKI secures cloud-based data by preventing unauthorized access, enabling safe transactions, and providing digital signatures that guarantee data integrity.
Restraints
Despite strong growth potential, PKI implementation remains complex. Organizations face challenges integrating PKI with existing infrastructure, managing certificates, and ensuring compliance. Certificate expiration, device proliferation, and rapidly evolving security standards increase operational burdens for SecOps teams. These challenges limit PKI adoption among companies lacking specialized expertise.
Cloud deployment will record the highest CAGR due to its accessibility, scalability, and cost-effectiveness for SMEs. Meanwhile, on-premises PKI dominated in 2024 due to stricter data control requirements in BFSI, healthcare, and government sectors.
By enterprise type, SMEs are expected to grow fastest owing to rising security needs and limited IT resources. Large enterprises held the largest share in 2024 due to significant investments in digital identity frameworks.
Among applications, application performance management will lead growth, while network & security management maintained the largest share in 2024 due to the rising need for encrypted communication.
In 2024, the IT & telecom sector held the highest share, driven by digitalization, cloud usage, and high data volumes. Manufacturing, BFSI, and healthcare are also poised for strong demand due to rising cybersecurity risks.
North America recorded USD 2.32 billion in market value in 2024, supported by major PKI providers and mature IT infrastructure. Asia Pacific is expected to achieve the highest CAGR due to increasing cyberattacks and cloud adoption across China, India, Japan, and Australia. Europe is experiencing moderate but steady growth driven by regulatory compliance initiatives. The Middle East & Africa is emerging as the second-fastest-growing region, while South America shows accelerating adoption driven by digital transformation programs.
Conclusion
