How Do You Build a Resilient Cloud That Can Withstand Attacks?

The Approach of the Resilient Cloud 

The approach of the Resilient Cloud is driven by the large-scale implementation of IT applications in the cloud. As a result, applications run more smoothly and comply with modern standards, but at the same time, they are exposed to a new, larger attack surface. In cloud applications, various potential risks arise, such as: 

• A strong dependence on APIs, which may be insecure
• Data stored on a possibly misconfigured server
• The risk of forgotten implementations that were once set up and then lost from sight, now forming a security risk 

Security risks have now increased to such an extent that recent data shows security is the most important factor for cloud infrastructure success. No less than 81% of organizations consider it a top priority. This puts it ahead of other important aspects: scaling infrastructure (75%), the ability to ensure uptime and availability (75%), and budget (74%), all ranking lower. 

Approaching Cloud Security and Cyber Resilience Holistically 

In essence, the Resilient Cloud is a concept that aligns with companies' security concerns. To realize a Resilient Cloud, it is crucial to take two overarching steps within your security strategy:   

• A set of measures within a cloud platform that can act preventively
• A SOC service that proactively acts from a detection and response perspective

Looking at how Cegeka approaches it, they strongly emphasize combining both aspects. This creates comprehensive visibility, which in turn allows for better risk assessment.

Setting up a Resilient Cloud therefore starts with a solid foundation. Cegeka chooses Azure landing zones for this purpose—configured environments that provide essential functions for access control, encryption, and logging. With this foundation, workloads can run in a controlled environment, helping organizations align with strict regulations such as the NIS2 directive or DORA for financial institutions. While compliance remains the responsibility of each organization, this approach supports regulatory adherence and provides a secure framework for future growth in the cloud. 

Cegeka combines this preventive approach with a managed Security Operations Center (SOC) that monitors threats 24/7 and deeply integrates with Microsoft technologies Azure Sentinel and Defender for Cloud. The SOC has real-time visibility into the digital landscape, enabling threats to be detected and addressed quickly. Due to this strong integration, a security framework is created that minimizes risks and simplifies compliance. This last aspect is crucial for companies in regulated sectors, which often have to comply with strict requirements. 

A Resilient Cloud Is Not Static 

A Resilient Cloud should certainly not be approached statically. It requires continuous attention and testing to identify areas for improving your strategy. This can be done by: 

• Updating the mentioned technologies
• Adjusting processes
• Changing human behavior
• This way, your security strategy remains effective against evolving and new threats

The Impact of the Resilient Cloud 

The power of a Resilient Cloud lies in the synergy between security, resilience, and operational efficiency. By strengthening the foundation of cloud environments, the chance of incidents is drastically reduced. At the same time, integrating an SOC enables immediate intervention in the event of complex threats. For businesses, this means: 

• A higher level of protection
• More efficient use of IT resources
• Reduced workload for IT teams, as routine issues are automatically handled 

Compliance focus, ensuring companies can demonstrate to auditors and stakeholders that they meet regulations.

The Resilient Cloud offers companies a pathway to a safer and more resilient digital future. By integrating security from the foundation and combining proactive monitoring with preventive measures, organizations can both counter threats and prepare for future challenges. This also includes rapid recovery, ensuring operations remain as uninterrupted as possible. 

Cegeka, with its deep expertise and holistic approach, assumes that a Resilient Cloud is not only achievable but also a step toward a future-proof IT infrastructure. By bringing security and resilience together, a foundation is created on which organizations can build—even in an era of increasing cyber threats.
