GlobalSign is a WebTrust-certified certificate authority (CAs) and provider of Identity Services.[3] As of January 2015, Globalsign was the 4th largest certificate authority in the world according to the Netcraft survey. [4]

The company introduced a new all-in-one cloud-based document signing software, GMO Sign, for automated document signing processes, cloud-based document management with storage, online signature request system that is multi-signature (electronic, digital, signing seal) friendly.[5]


GlobalSign was founded in Belgium in 1996 and acquired in 2007 by GMO group in Japan (formerly GeoTrust Japan).[1][6] As of January 2015, Globalsign was the 4th largest certificate authority in the world according to the Netcraft survey. [4] GlobalSign was the first CA to improve revocation checking for HTTPS pages through the use of a CDN,[7] and the company was also the first to offer IPv6 compliant revocation services ("CRL").[8]


GlobalSign provides PKI and Identity and Access Management services to manage internal and external identities for the Internet of Everything. GlobalSign’s PKI services include a trusted root-chaining program for trusted PKI deployments, which allows the widely distributed and trusted GlobalSign root CA certificates to cryptographically chain subordinate root CAs for use in Microsoft CA and in other in-house CAs.[9]

GlobalSign also provides certificates to authenticate IoT to address authentication needs in the Internet of Everything (IoE) market.[10] In November 2012, GlobalSign launched an online service that allows website administrators to confirm that they have correctly configured SSL across their websites and receive actionable guidance on how to remediate any faulty or exploitable SSL configurations.[11]

The company has offices in the US, Europe and throughout Asia.


In 2014 GlobalSign acquired Helsinki-based Ubisecure Solutions, Inc., a privately held identity and access management (IAM) software developer. Ubisecure was spun out of GlobalSign in 2016.[12]

2011 hacking incident[edit]

In September 2011, GlobalSign suspended issuing authentication certificates temporarily after an anonymous hacker compromised their servers.[13] An Iranian student self-identified as "Comodohacker", who also claimed responsibility for the 2011 Comodo and DigiNotar breaches,[14] claimed that he had also hacked the systems of GlobalSign.[15] GlobalSign took the claim seriously enough to halt the signing/issuing of new certificates while investigating the claims; it resumed issuing certificates a week later.[16]

Dutch security company Fox-IT was contracted to analyze the breach and GlobalSign released a security incident report.[17] On December 13, 2011 GlobalSign released its final report on the incident. The report concluded that while GlobalSign's own web server was breached and the certificate of this server was stolen, due to the air gap separating this web server from the certificate-issuing machine (the one holding the company's root certificate), there was no evidence of any rogue certificates issued or any customer data exposed, thus the remedial actions were limited to cancelling their own web server's certificate and patching its software.[16][17] Sophos’s Chester Wisniewski summarized the report and GlobalSign’s response to the incident on his blog and concluded "Not only is the report thorough and convincing, but it appears that GlobalSign took every action, exactly as they should have, both during and after the incident."[18]
