SIKUR

SIKUR is a São Paulo-based provider of encrypted communications and data protection technology, positioning itself as a zero-trust alternative to consumer messaging and mobile platforms for organizations handling sensitive information. Its core product is a secure communication platform that encrypts messaging, voice/video calls, and document sharing at the source, layered on top of standard mobile operating systems rather than requiring a fully custom OS. The company also sells the Sikur One, a hardened Android handset built on Sony hardware, aimed at government and corporate buyers who want centrally managed, tamper-resistant devices rather than relying on carrier or OEM security postures alone.

Founded in 2014, SIKUR has since diversified into passwordless authentication, offering an SDK that lets other developers embed device-based cryptographic login into their own mobile and web applications without a shared secret that can be phished or leaked. It has raised institutional funding, including a Series A round backed by DXA Invest, and reports operations spanning Latin America, the US, and Europe, though independent third-party verification of usage scale is limited.

Its pitch is aimed principally at governments and regulated enterprises in Latin America concerned about interception of official communications, rather than the broader enterprise-collaboration-security market dominated by larger platform vendors. That regional focus is a real differentiator but also caps its addressable market and visibility outside the region.
