According to the report “The State of Zero Trust Transformation 2023” by cloud security firm Zscaler, more than 90% of IT leaders who have started migrating to the cloud have implemented or are planning to implement a zero-trust security architecture. This approach, which is based on the principle that no user, device, or application should be inherently trusted, is seen as the ideal framework for securing enterprise users, workloads, and IoT/OT environments in a highly distributed and mobile-centric world.
Implementing a zero-trust model can bring advantages, like reducing the risk of data breaches and other security incidents by requiring all access to be carefully verified and controlled. With a zero-trust model, organizations can grant access to resources and systems on an as-needed basis, rather than relying on a perimeter-based approach. This can be especially useful for organizations with distributed workforces or that need to grant access to external partners or vendors. In addition, a zero-trust model can help organizations to meet various compliance requirements, such as those related to data protection and privacy.
At the same time, implementing a zero-trust model can be complex, and may require significant investment in security infrastructure and resources. The added security measures required may lead to longer login times and other delays, which can impact productivity and users may find the additional security measures required by a zero-trust model to be inconvenient, particularly if they need to authenticate multiple times or use different methods to access different resources.
The report also found that IT leaders see security, access, and complexity as the top concerns in the cloud and that traditional VPNs and perimeter-based firewalls are ineffective at protecting against cyberattacks or providing visibility into application traffic and attacks.
It’s worth noting that the specific pros and cons of implementing this model will depend on an organization’s specific needs and priorities. Organizations should carefully consider their security requirements and resources when deciding whether to implement a zero-trust model.
