AC Digital

What AC Digital does

AC Digital (legal name: ACDigital Autoridade Certificadora e Segurança Digital LTDA) is a Brazilian Level 1 Certification Authority operating within the ICP-Brasil public key infrastructure, regulated by ITI. Founded in 2011 and headquartered in Porto Alegre, Rio Grande do Sul, the company issues legally valid digital certificates for individuals (e-PF / e-CPF) and legal entities (e-PJ / e-CNPJ) in two formats: A1 (software-stored, up to 12 months validity) and A3 (hardware-stored on tokens or smart cards, up to 36 months validity). It also resells supporting hardware — USB tokens, smart cards, and card readers from OEMs including Morpho, G&D Burti, Safenet, Feitian, and Oberthur — and distributes a proprietary Windows/Linux issuance client (Emissor AC Digital).

Underlying technology is centered on ICP-Brasil-compliant cryptography for digital signatures, identity verification, and secure document signing, supplemented by an LGPD-compliant secure video conference validation platform that supports remote certificate issuance. The company generates revenue primarily through one-time sales of certificates (A1 and A3) and hardware media, plus professional services for validation and issuance. Distribution runs through the company's e-commerce website (acdigital.com.br) and a nationwide network of Autoridades de Registro (AR) partners that handle in-person and remote identity validation, with customer support via chat, phone, and dedicated FAQ/support portals.

The customer base is horizontal: individual consumers using certificates for tax filing (IRPF), government portal access, and personal document signing, alongside businesses using e-CNPJ for electronic invoicing (NF-e), SPED, Receita Federal access, SISCOMEX, and Conectividade Social. The company is privately held, has 51-100 employees, and does not publicly disclose revenue, funding, ownership structure, or pricing.

Broad incumbents

• Serasa Experian: Dominant Brazilian credit bureau and identity verification platform that issues digital certificates and broader identity services as part of a much wider portfolio — overlapping with AC Digital's e-CPF/e-CNPJ offerings but operating at a much larger scale and broader scope.
• GlobalSign: International PKI and digital certificate authority offering SSL, identity, and digital signature certificates globally — broadly comparable technology and category to AC Digital, but serving a different (international) customer base.
• DigiCert: Global leader in TLS/SSL and digital identity certificates with a comprehensive PKI platform — overlaps with AC Digital's certificate issuance and trust services but operates globally and at substantially larger scale.
• DocuSign: Global leader in electronic signature and digital transaction management — adjacent to AC Digital's certificate-based signing value proposition but operates as a SaaS platform rather than a regulatory-accredited certificate authority.
