The Public Key Infrastructure (PKI) Market in the UK is driven by increasing cybersecurity threats, compliance with stringent data privacy regulations such as the GDPR, and the need for secure digital assets and communications. Additionally, rapid digitization in both the private and public sectors specifically in the finance and healthcare vertical has propelled the demand for robust authentication and authorization mechanisms heightening the PKI demand. Furthermore, IoT innovations and the government’s digital-first public services, emphasizing data integrity and citizen privacy create opportunities for the PKI market.

In June 2023, GlobalSign with offices in Boston and London, advises businesses to brace for substantial changes in the PKI market from late 2023 through 2024. Among the critical updates are Google’s decision to reduce the lifespan of SSL/TLS certificates from 398 days to a mere 90 days, new baseline requirements for email security by the CA/Browser Forum, and Mozilla’s plans to distrust older root certificates. These changes will necessitate organizations to re-evaluate and adapt their PKI configurations for continued security compliance. GlobalSign has assured businesses of its support in navigating these market shifts, emphasizing the necessity for businesses to adjust their PKI security and automation posture promptly.

In January 2023, InfoCert S.p.A. confirmed its acquisition of a 65% stake in Ascertia which will be now under InfoCert’s aegis and will persist as a dominant provider for Trust Service Providers (TSPs). This merger enhances Ascertia’s offerings in the digital signature and PKI domain. The companies are aligned in their vision for digital trust, and their collective strategy entails introducing a comprehensive suite of digital trust tools that encompass PKI software, digital signature solutions, and Common Criteria-certified appliances.  

In March 2021, Thales (France), in collaboration with Ascertia (UK) unveiled a high-trust solution catering to the UK’s PKI market needs. The joint venture emphasizes PKI technology, optimizing business protection through robust identity and authentication systems. By harnessing digital signatures, the solution enhances efficiency, eliminating paperwork and hastening sign-off processes.

In the government sector, the NHS Digital Services Spine, an integral component of health and social care data communication, mandates that all connecting organizations possess a valid PKI certificate to ensure the encrypted and secure transmission of patient data. With the impending expiration of the first-generation (G1) certificates in 2024, the NHS has proactively recommended a transition to the second-generation (G2) certificates by the end of 2023. This shift aims to preemptively address potential service disruptions and further enhance data security measures, reflecting the UK’s commitment to bolstering its digital infrastructure in critical sectors like healthcare. This proactive measure within the NHS is indicative of the broader emphasis on fortified digital security across the UK.

Furthermore, In November 2020, the UK’s National Cyber Security Centre (NCSC) released vital guidance on the design and implementation of privately hosted PKI. This public initiative is tailored for the public sector, large organizations, and cybersecurity experts, emphasizing the significance of PKI in digital security. The guidance also highlights the challenges posed by quantum computing and the need for future quantum-resistant algorithms. The directive exemplifies the UK’s commitment to maintaining a robust digital security framework.
