About Netstream
Netstream AG is a leading Swiss data center operator specializing in secure infrastructure services. Founded in 1998, Netstream offers IT solutions that are both secure and user-friendly. With four data centers in the Greater Zurich area, the company flexibly delivers complex projects for clients such as Joyn (Seven.One Entertainment Group), DQ Solutions, Sunrise, Migros, and many others.
The Challenge
Netstream was already ISO 27001 certified and preparing for its next recertification. Despite having an existing system in place, managing risk assessments, documentation, and evidence across multiple tools, systems, and external consultants had become increasingly complex and resource-intensive.
Netstream’s goals:
- Improve traceability and structure within the ISMS
- Consolidate tools and reduce reliance on external parties
- Leverage automation to reduce manual workload
- Align with the updated ISO 27001 standard
The objective was not to replace an inadequate system, but to optimize and future-proof the certification process through better usability and efficiency.
The Solution
Netstream chose Kertos not only to support the recertification process, but to simplify and centralize its information security management holistically.
Although the external certification schedule remained the same as the previous year, the internal process became significantly more structured, transparent, and easier to follow.
With Kertos, Netstream was able to:
- Migrate and organize existing documentation into a single platform
- Gain greater transparency over risk management and ISMS processes
- Reduce its tool landscape by consolidating systems, audit tracking, and consultancy
- Prepare for the recertification efficiently with clear workflows
Kertos’ Customer Success team supported the entire process. The external auditor especially praised the clarity, documentation quality, and well-structured nature of the platform.
The Result
With Kertos, Netstream not only completed its ISO 27001 recertification successfully but also measurably improved its internal structures and integrated its systems more efficiently.
Rather than just reducing effort, the key benefit was a structural improvement with a clearer audit trail—all while lowering compliance costs through tool consolidation and reduced need for external consultants.
Key Outcomes
- Successful ISO 27001 recertification with full audit clearance
- Streamlined ISMS structure with improved traceability
- Positive feedback from the auditor on platform clarity and documentation
- Lower compliance costs through system consolidation
