Client
Finnish crypto company Tesseract offers customers a technology-based service for yield distribution and generation. Tesseract operates an extensive portfolio and handles sensitive customer information. COO Wuoristo says that security is key to the company’s business model. “We handle money that runs into the hundreds of millions, so our Information Security Management System (ISMS) and our ability to ensure the highest level of trust and compliance is critical,” Wuoristo explains.
In an industry that is not always focused on security or meeting compliance requirements, Tesseract is committed to leading the way. “We want to move the industry towards more maturity, which means regulation and compliance. This leads to improved security and trust, which enables customers to invest with confidence,” Wuoristo emphasizes.
Partnership
How did Reversec help?
On the compliance front, Tesseract’s in-house team had already successfully tackled the Service Organization Control Type 2 (SOC2) audit. When it came to the rigorous process of ISO/IEC 27001 certification, the team quickly realized it could benefit from external support.
“We wanted to partner with someone who had experience with the actual processes and insights, so that we could avoid making the same mistakes that everyone else has made,” Wuoristo explains.
Tesseract had previously worked with Reversec on penetration testing and validating the company’s platform and in-house technical capabilities. These positive experiences, combined with Reversec’s reputation as a leading player in the cybersecurity space, led Tesseract to choose our CISO as a Service offering.
The service allows organizations to completely outsource the CISO function to us. Alternatively, as with Tesseract, we can support your in-house CISO in a way that works best for you.
For Tesseract, this option meant shared responsibilities and support based on a deep understanding of the company. “It’s given us a two-person-led team where the more tactical day-to-day responsibility sits with us, and we’re able to move a lot of the planning and thinking to Reversec.”
Outcome
Our team helped Tesseract prepare for the ISO 27001 audit by mapping out the steps in the process, sharing guidance on structuring the policies, and supporting Tesseract’s team through the audit itself.
The team worked together so well that, after receiving their compliance certificates, Tesseract has continued to collaborate with us to maintain and develop the company’s overall ISMS information security management system, making governance a part of its regular day-to-day operations. “Reversec understands the importance of security for our business, and the speed at which we need to operate,” Wuoristo explains.
Strong experience and understanding of the business environment
As Wuoristo puts it, it’s better not to make first-time mistakes if you can avoid them. The ability to buy that experience from Reversec is meaningful and adds plenty of value. “To have someone who has the bandwidth and experience to put all our InfoSec ducks in a row and help us prioritize what needs attention really helps us utilize our resources as effectively as possible.”
The cybersecurity landscape continues to evolve. As attackers learn increasingly sophisticated ways to infiltrate organizations, Wuoristo says that working with one of the industry leaders just makes sense. “Reversec plays a valuable role in ensuring our company, operations and systems are ‘battle-tested’ and secure against the threats we may face.”
What advice does Wuoristo have for companies like Tesseract that essentially operate in the trust business? “If you’re in fintech and take external threats seriously, then you would benefit from partnering with someone who specializes in trust. And Reversec is certainly a very strong option.”
