emerging technology

Autonomous AI agents are rapidly becoming part of enterprise workflows, shifting the core challenge of digital transformation from capability to trust. As agents begin making decisions, interacting with systems and executing tasks independently, enterprises must verify not only who an agent is, but what it is authorized to do and under whose authority it operates. Traditional IAM and PKI models are not equipped for this shift, prompting the emergence of new standards such as the Agent Name Service (ANS), which provides a global, PKI-backed identity and capability directory for AI agents. AI agents introduce dynamic, fast-changing identity lifecycles, cross‑ecosystem interactions and authorization needs that require cryptographic integrity and lifecycle governance. Early data from the HID PKI Market Study shows that certificates for AI agents are becoming a major driver of PKI modernization — outpacing even post‑quantum planning. Without strong identity controls, enterprises face new risks including impersonation, registry poisoning and large-scale Sybil attacks. Standards like ANS aim to mitigate these threats by establishing verifiable identity, provenance and authority for every agent. As organizations increasingly rely on autonomous systems, extending PKI, Zero Trust and IAM frameworks to cover non‑human identities is essential for securing the next generation of digital operations.

As organizations rely more heavily on encrypted communications and certificate-based security, effective PKI management has become a critical component of cybersecurity. While PKI provides strong encryption and identity assurance, poor certificate management can undermine its effectiveness and create significant security risks. Common challenges include self-issued certificates that lack centralized oversight, infrequent certificate rotation and manual processes that cannot scale with growing certificate volumes. These issues often stem from human error, insufficient planning and limited visibility into certificate inventories. To strengthen PKI security, organizations should focus on proven best practices such as designing certificate architectures carefully, maintaining comprehensive certificate inventories, protecting root and issuing keys with secure storage mechanisms, automating certificate lifecycle management and regularly rotating certificates and cryptographic keys. Automated PKI management solutions help reduce operational burdens, minimize human error and improve scalability while ensuring consistent adherence to security standards. By combining strong governance with automation, organizations can improve data protection, reduce risk and maintain a reliable certificate infrastructure.

As organizations adopt hybrid cloud environments and face increasingly sophisticated cyber threats, Public Key Infrastructure (PKI) remains a critical tool for securing users, devices, applications and machine-to-machine communications. However, deploying and managing PKI internally can be complex, requiring specialized expertise, ongoing maintenance and significant investment to keep pace with evolving security and compliance requirements. These challenges are driving organizations toward managed PKI-as-a-Service (PKIaaS) solutions that simplify operations while maintaining strong security and control. Cloud-based PKIaaS enables organizations to outsource the complexity of certificate management while gaining scalability, operational efficiency and compliance support. Benefits include automated certificate lifecycle management, centralized visibility, flexible deployment options, integration with enterprise tools and the ability to quickly expand security services without additional infrastructure investments. By leveraging managed PKI services, organizations can improve security, reduce operational burdens and support modern hybrid environments with a scalable, cost-effective foundation for digital trust.

FIDO2 is an open authentication standard designed to provide secure, phishing‑resistant and passwordless access to online services. Built on WebAuthn and the Client-to-Authenticator Protocol (CTAP), FIDO2 uses public‑key cryptography to authenticate users through security keys, smart cards or mobile devices. Its simplicity, low deployment cost and strong protection against credential theft have driven rapid adoption among enterprises looking to strengthen authentication while improving user experience. While FIDO2 and PKI both rely on asymmetric cryptography, they serve different but complementary purposes. FIDO2 focuses on user authentication and passwordless access, whereas PKI provides a broader framework for identity management, encryption, digital signatures and secure communications. Organizations increasingly deploy FIDO2 as a lightweight authentication layer alongside existing PKI infrastructure, using FIDO2 for secure logins and PKI for protecting applications, devices, documents and machine-to-machine communications. Together, these technologies help reduce phishing risk, strengthen identity assurance and support modern Zero Trust security strategies.
