GlobalSign

Overview

Founded in 1996 as a subsidiary of the GMO Internet Group, Japan, GlobalSign is one of the world's longest-running commercial SSL certificate authorities. Originally headquartered in the UK, GlobalSign now operates globally with service centers across North America, Europe, and Asia-Pacific, covering 150+ countries. As one of the earliest CAs to earn WebTrust certification, GlobalSign brings nearly 30 years of PKI expertise and operational stability.

GlobalSign is particularly known for its enterprise PKI solutions. Beyond standard SSL/TLS certificates, its core differentiators are managed PKI (MPKI), IoT device identity management, document signing certificates, and code signing certificates. The Atlas unified management portal supports full certificate lifecycle management with REST API and ACME protocol integration. GlobalSign maintains a particularly strong presence in Asia-Pacific markets, especially Japan and Southeast Asia.

Key Strengths

• Nearly 30 Years of Industry Experience: Operating since 1996, GlobalSign was among the first CAs to earn WebTrust certification. Its deep PKI expertise and long-term operational stability make it a trusted choice for enterprise customers. See CDN and SSL/TLS configuration best practices for guidance on validation levels.
• Full Certificate Product Lineup: DV (minutes), OV (1-3 business days), EV (1-5 business days), wildcard, and multi-domain (SAN) certificates. Over 1 million certificates issued annually, serving everything from personal websites to multinational enterprises.
• Enterprise Managed PKI (MPKI): GlobalSign's core differentiator. Organizations gain full PKI capabilities including dedicated CA hierarchy, custom certificate policy definition, CRL/OCSP publishing, and HSM key protection — without building their own CA infrastructure. Combined with security strategies, it enables end-to-end encryption trust frameworks.
• IoT Device Identity Management: GlobalSign IoT provides large-scale device identity solutions supporting MQTT, TLS, and DTLS protocols for industrial IoT, connected vehicles, and smart city applications. Device certificates can be bulk-issued via API and are deployed in major manufacturing projects across Asia.
• ACME Protocol & Automation: GlobalSign offers ACME protocol services for automated DV certificate enrollment and renewal. The Atlas portal also provides REST API for integration with environment deployment pipelines and ITSM tools like ServiceNow and Jira.

Product Ecosystem

Atlas Management Portal

Atlas is GlobalSign's unified certificate management platform offering certificate enrollment, approval, deployment, monitoring, and reporting. Supports multi-tier role-based access (administrators, approvers, requesters) suited for enterprise organizational approval workflows. Atlas provides REST API for third-party system integration, supporting connections with ServiceNow, Jira, and other ITSM platforms.

Managed PKI (MPKI)

GlobalSign MPKI targets organizations needing private CA capabilities without building the infrastructure. Services include: dedicated CA hierarchy (Root + Issuing CA), custom certificate templates and policies, CRL/OCSP publishing, HSM key protection, and audit logs. Ideal for finance, government, and large enterprises requiring private CAs, significantly reducing the infrastructure investment and operational costs of self-built PKI.

IoT Security

GlobalSign IoT Identity provides end-to-end device enrollment, certificate issuance, and identity authentication. Supports bulk device registration and certificate issuance, compatible with major IoT protocols and hardware security modules. Typical applications include industrial sensor authentication, smart grid device identity, and connected vehicle V2X communications, with MQTT and TLS mutual authentication for device-level identity verification.

Document & Code Signing

GlobalSign offers Adobe Approved Trust List (AATL)-certified document signing certificates and Microsoft Authenticode code signing certificates. Document signing certificates integrate seamlessly with Adobe Acrobat and Microsoft Office for e-contract and PDF signing workflows.

Limitations

• Enterprise Pricing Barrier: GlobalSign's pricing targets mid-to-large enterprises. DV certificates $60-$120/yr, OV $150-$400/yr, EV $300-$800/yr — between DigiCert and Sectigo. Individual users and small businesses on a budget should consider Sectigo or Let's Encrypt.
• Atlas Portal UX: Feature-complete but the UI/UX design feels traditional. Navigation logic and batch operations are less modern than DigiCert's CertCentral. New users need adjustment time and initial setup may require GlobalSign technical support assistance.
• Regional Brand Recognition Gap: Strong in Asia-Pacific (especially Japan and Southeast Asia) but brand awareness in North America and Europe trails DigiCert and Sectigo. Global SSL market share is being gradually eroded by competitors in Western markets.
• Weak Individual Market Coverage: Product focus and marketing are enterprise-oriented. Self-service purchasing and deployment experience for personal sites and small businesses are less convenient than Let's Encrypt and ZeroSSL. Entry-level product acquisition involves more steps than competitors.

Use Cases

• Large Enterprise PKI Deployment (★★★★★): First choice for organizations needing private or managed PKI. GlobalSign MPKI provides a complete CA hosting solution. Pair with CDN acceleration for global access optimization.
• IoT Device Identity Authentication (★★★★★): IoT Identity is ideal for manufacturing, energy, and connected vehicle industries requiring large-scale device certificate management.
• Government & Financial Institutions (★★★★): WebTrust certification and enterprise compliance capabilities meet the stringent requirements of high-security industries, particularly valued in Asia-Pacific government projects.
• Multinational Enterprise SSL Deployment (★★★★): Global service centers across North America, Europe, and Asia-Pacific suit multi-region operations.
• Personal Websites/Blogs (★★): Overpriced with less convenient self-service experience. Choose Let's Encrypt or ZeroSSL instead.

Pricing

Note: Prices vary by reseller and promotions. Enterprise PKI managed services require custom quotes.

FAQ

• What's the difference between GlobalSign and DigiCert? Both are enterprise-grade CAs. GlobalSign's edge lies in managed PKI (MPKI) and IoT identity management, with strong Asia-Pacific presence backed by the GMO Group. DigiCert excels in its CertCentral platform and global brand reach. Choose based on your region and specific PKI requirements—see CDN and SSL/TLS configuration best practices.
• Is GlobalSign suitable for SMBs? Yes for SMBs needing organizational validation (OV/EV) with moderate budgets. Individual users should choose free Let's Encrypt certificates. See CDN and SSL/TLS configuration best practices for selection guidance.
• Does GlobalSign support the ACME protocol? Yes. GlobalSign ACME service supports automated DV certificate enrollment and renewal, compatible with Certbot, acme.sh, and other ACME clients — ideal for DevOps automation—see CDN and SSL/TLS configuration best practices.
• What is managed PKI (MPKI)? MPKI is a service where GlobalSign operates CA infrastructure on behalf of the enterprise. Organizations get full PKI capabilities — CA management, certificate policies, CRL/OCSP — without building HSM, CA servers, or OCSP responders, while retaining full control over certificate policies. This is GlobalSign's core differentiator from most SSL certificate providers—see CDN and SSL/TLS configuration best practices.
