ADACOM

ADACOM, headquartered in Athens, Greece, operates two connected lines of business: a Trust Services division that issues qualified digital certificates and remote electronic signatures under the EU’s eIDAS regulation, and a Cybersecurity division that provides PKI deployment, threat intelligence, vulnerability management, incident response, and managed security services. Its Trust Services are registered with the Greek national regulator (EETT) and listed on the EU Trusted List, and the company operates a public key infrastructure (ADACOM MPKI) used by organizations to centrally manage certificates across systems, devices, email, and users.

Founded in 1997, ADACOM has grown over more than 25 years into a Byte Computer subsidiary with operations in Greece, Cyprus, and Bahrain, reporting roughly 208 employees and EUR 27.9 million in annual revenue as of its most recent disclosed fiscal year. It serves customers in more than 30 countries across EMEA, holding over 400 individual staff certifications across its technical teams and undergoing regular independent conformity audits of its qualified trust services under eIDAS.

ADACOM’s differentiation is combining regulated, audited digital identity infrastructure (qualified certificates and signatures) with broader cybersecurity integration and managed services, giving it a foothold in identity and trust that pure-play MSSPs and generic IT integrators lack. Its scores here reflect a financially established, audited regional player whose growth is tied to steady EMEA compliance and identity-infrastructure demand rather than fast product-led disruption.
