ESKA Experts Highlight the Cybersecurity Advantages of Cloud Migration

Experts from ESKA emphasize several significant cybersecurity advantages of cloud migration that have proven particularly beneficial for our clients who have already transitioned to cloud technologies:


  • Cloud services offer cybersecurity frameworks and security configuration standards, making it easy and effective to ensure security not only in public clouds but universally across the entire infrastructure. The use of ready-made tools in public clouds allows for the instant implementation of cutting-edge cybersecurity measures, enhancing the reliability and convenience of working with data.

Reconfigured Security Controls:

  • Reconfigured security controls provide robust protection not only for cloud management but also for the entire infrastructure. The integration of built-in tools makes the use of cloud services even simpler and more reliable.

Simplified Compliance Audits:

  • One compliance advantage is that the adoption of cloud services simplifies the process of obtaining certifications and undergoing compliance audits. The majority of required processes are already built into certified public clouds, automatically satisfying most security audit requirements. Existing certifications of public clouds can significantly facilitate the compliance audit process, ensuring organizations maintain an effective and high-quality level of security in accordance with established standards.

Risks of Transitioning to Cloud Services:

Data Security:

  • Cloud providers store data on remote servers, raising concerns about organizations having limited control over their data. Organizations seek assurance that their data is protected from unauthorized access.

Identity and Access Management (IAM):

  • Organizations need a clear overview of how users access resources and how the management of roles, rights, and privileges is handled. Confidence is crucial in ensuring that only authorized users have access to designated resources, and administrator accounts are secure and controlled. According to a Delinea study, 74% of data breaches are related to privilege abuse. To address these challenges, some organizations prefer transitioning from individual IAM solutions to commercial solutions like Privileged Access Management (PAM).

Data Transfer and Bandwidth Limitations:

  • Migrating a large volume of data to the cloud can be time-consuming and constrained by network bandwidth. Uploading or downloading substantial data volumes over the Internet can become a bottleneck, especially in conditions of limited network infrastructure.


  • Organizations must adhere to various regulations and standards such as GDPR, HIPAA, PCI-DSS, and others. Cloud providers may offer compliance tools, but organizations need to ensure full compliance on their part.

Key Management:

  • Inadequate configuration management and improper certificate management can lead to severe consequences. Thorough examination and implementation of best practices, such as centralized management, automated certificate management, secure key management, and compliance management, can help overcome these challenges and ensure the security of digital communications in the cloud.

Application Security:

  • Applications operating in the cloud are susceptible to the same traditional attacks as those outside the cloud. Transitioning to the cloud is an opportunity to establish a DevSecOps program to ensure the security of new or revamped applications from known attacks.

While transitioning to cloud services opens up broad perspectives, it is crucial to be aware of the risks and take measures to minimize them.

Priorities of Cloud Audit:

In terms of compliance, IT auditors must assess the organization's cloud environment's compliance with laws and standards such as GDPR and HIPAA. Implementing effective controls for data protection and confidentiality, including encryption and access control, is crucial. Data confidentiality requires attention to both cloud provider controls and organization policies. Proper data classification and the application of appropriate controls are essential. Vendor management is a key aspect, and auditors must ensure proper controls to mitigate risks. Monitoring performance, contract terms, and exit strategies is mandatory.
