Helsinki, Finland, 26 June 2025
At Tesseract, safeguarding our clients’ digital assets is a top priority. As a Helsinki-based institutional digital asset lender and yield service provider, we handle substantial volumes of capital—trust, compliance, and operational integrity are fundamental to everything we do.
To reinforce this commitment, we partnered with Reversec, a leading cybersecurity consultancy, to develop and strengthen our Information Security Management System (ISMS) and guide us toward ISO/IEC 27001 certification. This partnership has played a pivotal role in enhancing our internal security frameworks and aligning our compliance strategy with global standards.
“We handle money that runs into the hundreds of millions, so our ISMS and our ability to ensure the highest level of trust and compliance is critical,”
— Leo Wuoristo, Chief Operating Officer, Tesseract
Reversec’s CISO-as-a-Service offering provided a strategic layer to our in-house security and compliance efforts. Their team supported us through every step of the ISO/IEC 27001 journey—from identifying requirements and building scalable policy structures to implementing a robust ISMS fit for a rapidly evolving regulatory environment.
This tailored support allowed us to fast-track our readiness for certification, with Reversec working closely alongside our internal teams to deliver a comprehensive and practical compliance framework.
Our work with Reversec extends beyond certification. They continue to support us in refining our security operations and ensuring that our systems evolve in line with both the threat landscape and industry best practices. The collaboration stands as a model for how fintech companies can elevate their security maturity through thoughtful, expert partnerships.
We’re proud of what we’ve built—and the trust it reinforces with our clients, partners, and regulators.
