In the rapidly evolving landscape of cyber threats, data protection has become a priority concern. Traditional security models are proving inadequate in the face of sophisticated attacks, leading organizations to seek out more dynamic and robust approaches to securing their data. The integration of Secure Access Service Edge (SASE) and Zero Trust architectures offers a promising approach to modern cybersecurity challenges. In this blog, we delve into how Versa Networks merges SASE and Zero Trust to ensure the protection of data in today’s landscape.
The National Institute of Standards and Technology (NIST) has been instrumental in defining and disseminating the Zero Trust model. According to the NIST Special Publication 800-207, Zero Trust (ZT) is a set of cybersecurity paradigms that moves defenses from static network-based perimeters to focus on users, assets, and resources. A Zero Trust Architecture (ZTA), informed by these paradigms, is designed to plan, and manage industrial and enterprise infrastructure and workflows. It is predicated on the assumption that there is no implicit trust granted to assets or user accounts, regardless of their physical or network location. Zero Trust demands that authentication and authorization are discrete functions performed before a session to an enterprise resource is established. The movement toward Zero Trust is driven by enterprise network trends, including remote users, Bring Your Own Device (BYOD) policies, and cloud-based assets that fall outside traditional network boundaries. Zero Trust concentrates on securing individual resources and not traditional network segments. The full explanation and framework can be accessed through the NIST publication (NIST.SP.800-207).
This Zero Trust paradigm requires a mental shift in how organizations consider security. It’s not merely about implementing new technologies but also about adopting a new security mindset that permeates all aspects of IT operations.
In today’s workplace, where data, users, and devices frequently move physical locations, safeguarding sensitive information becomes a herculean task. SASE, or Secure Access Service Edge, is an emerging solution that combines security functions with software-defined wide area networking (SD-WAN) capabilities to support the dynamic, secure access needs of organizations. By merging these traditionally separate areas, SASE aims to create a flexible approach to security, networking, WAN, and analytics delivered via the cloud, on-premises, or as a blend of both.
Unified SASE is defined as being able to deliver all SASE features from a singular solution built on one operating system, not multiple products, and having one management console for all configuration and logging. Versa Networks is a leader in Unified SASE, providing the aforementioned solutions in an easy to deploy, elastic environment tailored to the needs of each customer. Versa Networks’ SASE solutions are designed to protect data regardless of where it’s accessed from, ensuring that the security perimeter extends to every endpoint.
Versa achieves this using a data-centric approach following the below best practices to ensure the highest level of data protection:
Versa doesn’t just use a data-centric approach though to ensure data protection but goes above and beyond by applying zero trust principles within its SASE solution to create a true synergy between data protection and zero Trust principles where unified security posture, enhanced data protection, and improved user experience are seamlessly integrated. This unified approach not only simplifies the security management process but also reduces the complexity traditionally associated with IT environments. Furthermore, the integration of Zero Trust’s stringent access controls within SASE’s cloud-native framework ensures that sensitive data remains secure under all circumstances. This powerful combination guarantees that no matter where a user is located or what device they are using, sensitive data remains inaccessible to unauthorized entities. Additionally, the fusion of SASE and Zero Trust significantly enhances the user experience. SASE’s efficient delivery of services, together with Zero Trust’s continuous verification processes, ensures that users enjoy secure, fast, and reliable access to necessary resources. This integrated strategy highlights how Zero Trust, user experience, and data protection are intricately fused together, offering a robust solution in the evolving landscape of digital security.
