ABI Research identifies top performers in innovation and implementation amid growing enterprise demand for trusted digital identity and certificate management.
NEW YORK, November 18, 2025 /PRNewswire/ — The explosive growth of crypto assets in enterprise environments creates data proliferation and asset visibility challenges that, combined with the increasing complexity of enterprise architectures and the looming quantum threat, require flexible PKI solutions and services that enable reliable and efficient certificate issuance, management and revocation. The new competitive ranking from the global technology monitoring firm ABI Search evaluates the top 11 enterprise PKI vendors based on technology development and deployment, commercialization, solution breadth and quantum security capabilities.
Market leaders: Keyfactor, Entrust, DigiCert, Guarantee, Sectigo and AppViewX
General public: CyberArk, GlobalSign, Ascertia, eMudhra and HID
“The assessment focused on 10 criteria across two critical categories: innovation and implementation,” explained lead analyst Aisling Dawson. “Innovation criteria included PKI configuration and capabilities, PKI and CLM service options, PKI management platforms, partner ecosystem and integrations, and quantum-secure capabilities. In the implementation category, the assessment included the range of offerings, supported applications, cryptographic capabilities (algorithms, protocols and certificates), standards and regulatory compliance, and go-to-market strategies.
Facing fierce competition, Keyfactor secured the first place in the competitive evaluation, providing the most flexible PKI solution with different deployment models and CA agnosticism. Keyfactor’s offerings represent PKI at the forefront of innovation, showcasing the advanced prowess of PKI-IoT applications and integrating new capabilities in asset mapping and crypto discovery. The company demonstrates an advanced understanding of emerging trends and needs in the broader PKI market, including the shift to the left and increasing focus on device and IoT security.
Close behind in second place, Entrust offers extensive PKI support in a truly platform-based manner, boasting a comprehensive in-house digital trust platform that addresses an unrivaled range of PKI applications, as well as one of the broadest integration portfolios and leading crypto consulting services, from PKI health checks to quantum migration planning.
DigiCert rounds out the top three with its DigiCert ONE platform, combining its expertise in public trust PKI and enterprise PKI to provide a platform with global reach, high scalability and availability, as well as innovative generative AI and agentic AI capabilities that enable efficient certificate management and issuance.
Following the top three is Garantir, a small enterprise PKI provider with a unique multi-tenant structure built from the ground up and specialized PKI capabilities in code signing and S/MIME use cases as well as strong crypto-agility features. Sectigo, with strong experience in public PKI and competitive automation capabilities, follows closely, followed by AppViewX, a leader and innovator in CLM and certificate discovery.
CyberArk and GlobalSign lead the consumer category, with CyberArk demonstrating crucial personalization features and powerful machine identity capabilities, while GlobalSign boasts a high certificate issuance and renewal rate and capitalizes on its unique positioning as a publicly trusted certificate authority and enterprise PKI provider, demonstrating advanced expertise in high-trust credential use cases and enjoying a strong brand reputation in both PKI sub-segments. At the lower end of the consumer category, Ascertia, eMudhra and HID bring strong enterprise PKI solutions to an increasingly competitive PKI market. Ascertia offers a highly pluggable PKI and CLM solution with extensive experience in government and financial domains. eMudhra is increasingly moving into North American and European markets with its competitively priced PKI suite, while HID offers a comprehensive and flexible PKIaaS offering that promises a fast time to value and a reliable predictive pricing model.
“The renewed emphasis on certificate hygiene, contextualized environment visibility and post-quantum anxieties is fueling growth and revenue in the enterprise PKI market segment,” Dawson said. “Driven by the growing need for managed professional services to deliver enterprise PKI, competition within the enterprise PKI market is intensifying. Once a fairly protected subsegment, the big players in public trust PKI are coming in to get a piece of the pie, while the continued convergence between PKI and CLM encourages what were once strictly CLM companies to expand their suite of enterprise PKI solutions and services.
These results come from the ABI Research study Enterprise PKI Providers report. This report is part of the company report Quantum security technologies research service, which includes research, data and ABI Insights.
