Description: Secure Access Service Edge (SASE) is a network architecture that combines wide area network (WAN) capabilities with network security functions, providing a comprehensive solution for connectivity and data protection in digital environments. This architecture is based on the premise that security should be a fundamental component of the network, not an afterthought. SASE integrates technologies such as network access security (NAS), cloud security, and network segmentation, allowing organizations to efficiently manage access and protect their resources. Additionally, it aligns with the zero trust model, which assumes that no entity, whether internal or external, should be trusted by default. This is especially relevant in a world where remote work and mobility are increasingly common. The implementation of SASE enables companies to adapt to the growing complexity of cyber threats while optimizing network performance and enhancing end-user experience. In summary, SASE represents a modern and holistic approach to security and connectivity in the digital age, facilitating the digital transformation of organizations.
History: The concept of SASE was introduced by Gartner in 2019 as a response to the growing complexity of network infrastructures and the need to integrate security into connectivity. As organizations adopted more flexible and distributed work models, it became clear that traditional security and network solutions were inadequate to address contemporary challenges. Since its introduction, SASE has rapidly evolved, with increased adoption by companies of various sizes and sectors, driven by digital transformation and the need for enhanced cloud security.
Uses: SASE is primarily used to provide a comprehensive security and connectivity solution in distributed work environments. It enables organizations to securely manage access to cloud applications and data, facilitating remote work and mobility. Additionally, SASE is useful for network segmentation, ensuring that sensitive data is protected and access is restricted according to security policies. It is also applied in the implementation of zero trust strategies, where the identity and context of users are continuously verified before granting access to resources.
Examples: A practical example of SASE is the implementation of a cloud security solution that allows employees to access corporate applications from anywhere while enforcing strict security policies. Companies like Zscaler and Cloudflare offer platforms that integrate SASE, enabling organizations to protect their data and optimize network performance. Another case is the use of SASE in organizations with hybrid work environments, where employees need secure access to corporate resources from different locations and devices.
