Secure Access Service Edge (SASE) is a new approach to networking and security that addresses the challenges of securely connecting users to cloud-based applications and services, as well as protecting against cyber threats. SASE combines traditional WAN functionality with advanced security features, such as firewalls, VPNs, and other security technologies, to provide a comprehensive solution for securing access to cloud resources.
The core of SASE is the concept of a “service edge,” which is a virtualized point of presence (POP) that is located closer to the user than the traditional data center. This allows for faster, more secure connections to cloud resources, as well as better protection against cyber threats. The service edge is where network and security services are integrated and delivered to users, providing a more flexible and efficient delivery of services to users, regardless of their location.
One of the key benefits of SASE is that it allows organizations to simplify their network and security infrastructure by consolidating traditional WAN and security functions into a single solution. This eliminates the need for separate WAN and security solutions, reducing complexity and improving security by providing a unified, end-to-end solution. The service edge also allows for more efficient delivery of services to users, as it is closer to them, providing faster and more secure connections.
SASE uses a variety of security technologies to secure the connection between the users and the cloud resources. Firewalls are used to control the traffic and allow only authorized traffic to pass through. VPNs are used to create a secure connection between the user and the cloud resources. Data Loss Prevention (DLP) is used to protect data while it is in transit and at rest. Cloud Access Security Brokers (CASB) are used to secure access to cloud resources and ensure compliance with regulations and standards.
Another important aspect of SASE is its ability to provide a consistent security policy across all access types, whether it be from branch offices, data centers, or the cloud. This enables organizations to have a unified view of the security posture across their network and to better defend against cyber threats. This also makes it easier to comply with regulations and standards as the security policy is consistent across all access types.
SASE also enables organizations to take advantage of new security technologies, such as zero trust and software-defined perimeter (SDP). Zero trust is a security model that assumes that all devices and users are potentially compromised and therefore must be authenticated and authorized before accessing resources. SDP, on the other hand, is a security model that creates a virtualized perimeter around a network, making it much more difficult for attackers to penetrate. These technologies are becoming increasingly important as cyber threats become more sophisticated and harder to detect.
When it comes to implementing SASE, SD-WAN is a critical component. SD-WAN provides the necessary visibility and control over the underlying network to ensure that traffic is directed to the optimal path, while also providing security and compliance capabilities. SASE-enabled SD-WAN solutions allow organizations to securely connect users to cloud-based applications and services, as well as protect against cyber threats. It also improves the performance of the applications by directing the traffic over the best path available.
In addition, SASE also offers the ability to integrate with other security tools, such as threat intelligence platforms, to provide a more complete security solution. By integrating threat intelligence, SASE can detect and block known threats before they can cause damage.
In conclusion, SASE is a powerful new approach to networking and security that can provide secure access to cloud-based applications and services, as well as protection against cyber threats. It simplifies the network and security infrastructure by consolidating traditional WAN and security functions into a single solution, enables organizations to take advantage of new security technologies, and improves the overall security posture. Implementing SASE on every SD-WAN solution is crucial for organizations as it provides a comprehensive solution for securely connecting users to cloud-based applications and services. With its ability to integrate with other security tools, provide consistent security policy, and protect against cyber-attacks, SASE is a crucial technology for organizations looking to adapt to the ever-changing threat landscape and keep their networks and data safe.
