SASE is a network security framework that addresses the work-from-anywhere mobility and agility businesses need. Choose a provider that offers a global SD-WAN footprint with points of presence in key regions, which reduces latency and allows security inspection to happen locally rather than being backhauled.
A SASE solution also combines multiple security technologies into a single architecture, simplifying management and reducing costs associated with point solutions like secure web gateways, CASBs, and firewall appliances.
What is SASE?
In a time of digital transformation, work-from-anywhere expectations, and growing cybersecurity risks, network and security solutions must evolve to support modern business. This means moving away from legacy architectures that impose performance and complexity penalties on the network and deploying security capabilities in the cloud where they can be easily accessed and managed. SASE solutions for worldwide cybersecurity are ideal for addressing challenges by delivering an SD-WAN with cloud-based security services.
The goal is to improve the user experience by avoiding traditional network choke points and reducing application performance degradation. It also helps reduce costs by eliminating hardware requirements, simplifying management through a single pane of glass, and minimizing operational overhead with updates that don’t require new HW or software. Finally, it allows ZTNA based on the user’s identity, device, or application rather than the IP address or physical location for seamless protection that extends to public WiFi.
Adopting SASE requires a commitment from networking and security teams to coordinate their systems. To achieve the most effective outcomes, consider a gradual rollout approach to allow you to learn from each phase and optimize your SASE implementation. Also, choose a vendor that offers MEF 3.0 certification to demonstrate their commitment to industry standards and offer assurances that your SASE solution will perform as expected.
What are the Benefits of SASE?
Modern enterprises require agility and scalability to support business transformation while providing users with the best experiences possible from anywhere. SASE enables businesses to meet these needs while delivering enterprise-level security.
SASE delivers cost savings through platform consolidation, consolidating multiple point products into a single cloud-delivered network security service model. It simplifies the IT infrastructure and reduces the tools IT teams have to manage. It also improves security and performance by applying security services based on identity rather than the device, location, or access network.
A SASE solution combines branch FWaaS, Secure Web Gateway, Zero Trust Access Networking (ZTNA), CASB, and Data Loss Prevention into a unified framework that can scale to the size of an organization and deliver advanced threat prevention capabilities. This approach to security enables organizations to provide secure remote access for any user or device while eliminating the threat of a breach or loss of sensitive data.
SASE can also reduce the technologies and providers required to support 24/7 security operations, simplifying technology integrations, daily network performance management, and security firewall alerts. However, this complexity calls for a managed solution with deployment-ready expertise and agility to help shorten the path to SASE success. SASE service delivers knowledge of the various cybersecurity point solutions that make up SASE and end-to-end expertise to ensure an easy and quick transition to a converged, scalable network security architecture that provides a robust, advanced defense against today’s advanced threats.
How to Implement SASE?
Getting started with SASE can be daunting for many network teams. Setting goals and objectives, understanding current knowledge and tech landscapes, and selecting a solution that can scale for the long term will help enterprises successfully transition to SASE.
Unlike legacy wide area networks, which use VPNs to connect users to applications and data, SASE integrates networking and security functions into a single, cloud-based solution. SASE allows secure access to cloud and enterprise applications without compromising performance. It requires a new approach to securing the modern distributed network.
The right SASE solutions will offer a better user experience and reduce network latency by inspecting traffic at the network’s edge. They will also provide intelligence for routing connections to internet exchanges and optimizing cloud application and service performance to ensure low latency. They will also provide security services like DNS, DDoS protection, and other capabilities to meet the needs of increasingly distributed networks.
Organizations must knock down internal walls to embrace SASE and create a unified network architecture. It requires security and network teams to collaborate and work together to understand their challenges, identify opportunities for improvement, and develop a roadmap for the future. Then, they must deploy a SASE architecture that addresses those long-term goals and delivers the results needed for success in the post-pandemic world.
What is the Future of SASE?
For years, security has been added as an overlay to networking solutions. With networks and threats evolving faster than ever, enterprises must shift their thinking. They need a new architecture to meet their security and network performance needs that work efficiently, seamlessly, and securely for users at any location or device.
This is why SASE is emerging as the networking solution for modern businesses. Based on the concept of edge computing, SASE pushes security and access close to users. Using an organization’s security policies, SASE dynamically allows or denies connections to applications and services. It helps eliminate the need for expensive MPLS lines while offering superior latency and performance over traditional VPNs.
Leading SASE solutions also include Zero Trust Networking (ZTNA), which ensures that the network never assumes trust for any user or device. This is achieved by ensuring that all access attempts are verified to be legitimate and not from malicious traffic or unauthorized IP addresses, such as man-in-the-middle attacks.
The most successful SASE deployments combine the network and security into a seamless, cloud-delivered service that scales with business demand. Picking a managed SASE provider can be complicated, as many different security capabilities and technologies must be tightly integrated into the platform. However, setting goals and understanding the right questions will help organizations choose a converged SASE platform that delivers long-term network performance and cyber security protection.
