Tested and certified to be secure: How five key security standards protect your company

The digital threat landscape is becoming more complex every day, and with it, the pressure on companies to ensure data security and regulatory compliance is growing. But how can you be sure that your cybersecurity partner isn’t just talking about protection, but also demonstrably practicing it? How do you know who you can trust with your most valuable digital assets?

The answer lies in independent, transparent, and globally recognized testing standards. These certifications and attestations should not be trophies in a cabinet, but rather the foundation of daily operations. Each of these badges has meaning, both for us and for you.

A holistic foundation: Why one standard alone is not enough

Modern threats are multi-layered. That’s why a single security standard is not enough to ensure comprehensive protection. An effective security concept is like a fortress with multiple lines of defense. Each of these certifications covers a different critical aspect and demonstrates our commitment to a holistic approach to security.

Security according to the highest national standards: BSI C5 & GDPR

For companies operating in Germany and Europe, local standards are of crucial importance. They create legal and investment security.

  • BSI C5 (Cloud Computing Compliance Criteria Catalogue): This criteria catalogue from the German Federal Office for Information Security (BSI) is the de facto standard for secure cloud computing in Germany. It ensures that a cloud provider meets strict information security requirements.

    Specifically, a BSI C5 attestation means that the relevant security controls have not only been designed and implemented but also evaluated and validated by an independent external auditor. This confirms that we work with clear security responsibilities, documented processes, and consistent control implementation.

    In Germany and in critical or regulated environments, C5 is one of the clearest signals of trust. This attestation reduces friction in your security reviews because requirements can be mapped to a known BSI framework instead of starting from scratch.
  • GDPR compliance: The General Data Protection Regulation is at the heart of European data protection. Our processes and technical measures are designed to support the principles of the GDPR and help you meet your own data protection obligations.

Globally recognized: International standards for trust without borders

In a globalized world, security standards must be understood and recognized internationally.

  • ISO/IEC 27001: This is the global gold standard for information security management systems (ISMS). ISO 27001 certification demonstrates that security is a structured, risk-based, and continuously improved process that is embedded throughout the entire organization.
  • SOC 2 Type 2: While other standards evaluate the design of controls, the SOC 2 Type 2 report goes a crucial step further. Over a period of several months, external auditors evaluate whether security controls are effective in daily operations in accordance with the Trust Service Criteria (security, availability, processing integrity, confidentiality, data protection). It is the ultimate practical test.
  • PCI DSS (Payment Card Industry Data Security Standard): This standard was developed by the credit card industry and sets extremely high requirements for the protection of payment card data. It shows that we meet even the most stringent security requirements for highly sensitive data – a strong signal of trust across all industries.

What this means for you in concrete terms: Your benefits at a glance

These certifications are more than just badges on the website. They offer you tangible benefits:

  • Simplified compliance: By meeting these standards, we provide you with the necessary evidence and make your own audits and risk assessments much easier.
  • Verifiable risk minimization: You don’t rely on promises, but on tested and proven security processes that demonstrably reduce your risk of data breaches and outages.
  • Increased trust: Show your own customers, partners, and insurers that you don’t compromise when choosing your protection solution. Working with a partner certified to the highest standards, such as Link11, strengthens your own position in the market.
