The rise of remote workforces is reshaping modern enterprise. Many organizations now hire from every corner of the world, and these global employees require fast and seamless access to corporate resources. However, the higher latency that results from connecting employees who are physically far apart can lead to:
To address these challenges, organizations require a global network that connects distributed employees efficiently, ensuring optimal connectivity and performance across all locations.
To overcome these challenges, organizations are turning to Secure Access Service Edge (SASE), a transformative, cloud-native architecture that combines networking and security capabilities into a single solution. SASE provides secure and efficient access to resources across this global network, enabling organizations to support remote and cloud-based environments with integrated security and optimized traffic routing.
SASE helps reduce latency for global employees by bringing resources and security controls closer to users, thereby improving network efficiency and ensuring a consistent and secure digital experience from anywhere in the world. Minimizing latency is a key goal of SASE deployments, but it is important to note that SASE architectures can also introduce network overhead that may impact performance, response times, and latency.
SASE architecture converges network and security functions into a unified service delivered at the cloud edge. SASE delivers integrated network and security services through a cloud-native security infrastructure, enhancing performance, reducing latency, and simplifying management for organizations.
To achieve this, SASE combines 5 core technologies:
SASE brings together various security solutions into a single platform, simplifying management and deployment for enterprises.
SASE SD-WAN is the primary technology impacting network performance and latency.
SD-WAN connects users, whether they are working onsite or remotely, to distributed resources using a software solution rather than traditional approaches that often relied on costly hardware. SASE integrates comprehensive security services directly into the network fabric, allowing security teams to manage access requests efficiently.
Previously, organizations would create Local Area Networks (LANs) at each branch to connect on-site users. LANs from multiple locations were then combined to form a Wide Area Network (WAN) using Multi-Protocol Label Switching (MPLS) infrastructure. This approach leases dedicated lines between locations, allowing traffic to travel quickly along predetermined paths.
While this enables fast connectivity between business locations, it requires costly hardware installation and maintenance. Traditional network infrastructure also increases operational complexity and can hinder efforts to streamline data flow, as managing multiple hardware components and disparate systems makes it difficult to optimize performance.
This legacy network architecture was also designed for connectivity between static, on-premises users. It works well, but for a business model that’s becoming outdated, when most employees and applications were centralized within corporate facilities.
As organizations embrace cloud computing, this architecture quickly creates problems. Remote users must use Virtual Private Networks (VPNs). to establish a secure connection to the internal network. By creating an encrypted tunnel and masking their IP address, employees can make it appear as if they were inside the local network, receiving the same access as an onsite user.
Unfortunately, remote access VPNs struggle to deliver low-latency connectivity for global employees.
With traditional networks, data is often routed back to the internal network for inspection and policy enforcement, a process known as backhauling.
This approach adds significant distance to every request. For example, a remote employee in Asia accessing an application hosted in Europe might see their traffic travel thousands of miles to a U.S. data center first, just for security checks. This inefficient routing leads to:
Deep security checks in SASE, such as SSL decryption and DLP scanning, can also introduce computational latency, which must be managed to maintain performance.
Since users and the resources they access are often outside the traditional network (i.e., remote users accessing cloud services), backhauling traffic no longer makes sense. A problem edge cloud SASE networks solve.
Effectively managing network traffic is fundamental to the success of Secure Access Service Edge (SASE) deployments. By converging network security and wide-area networking capabilities at the network edge, SASE ensures that security services and secure access are consistently applied, no matter where users or devices are located. This approach not only strengthens network security but also optimizes network performance by intelligently directing network traffic.
SASE leverages advanced techniques such as traffic shaping, Quality of Service (QoS) policies, and Software-Defined Wide Area Networking (SD-WAN) to prioritize critical applications and allocate network resources efficiently. These methods help organizations ensure that essential business applications receive the bandwidth and low-latency connections they require, while less critical traffic is managed appropriately. By positioning security features and WAN capabilities at the network edge, SASE minimizes unnecessary data hops and streamlines data flow, resulting in improved overall network performance and a stronger security posture.
With access service edge SASE, organizations can dynamically adapt to changing traffic patterns, reduce network congestion, and provide secure access to resources—no matter where employees are located. This ensures that global teams experience consistent, high-quality connectivity and that critical applications remain responsive and protected.
SASE SD-WAN uses software to intelligently route traffic across the most efficient path between users and the resources they’re accessing. These optimizations impact network performance by improving overall reliability and speed, while also improving security by ensuring efficient, secure data delivery.
Instead of relying on MPLS circuits and traditional VPNs, SD-WAN continuously monitors network conditions, automatically selecting the optimal path in real-time. This dynamic routing dramatically improves SASE global performance, ensuring that employees all around the world can connect to the resources they need with minimal delay.
SASE SD-WAN networking capabilities are delivered using a distributed network of nodes or Points of Presence (PoPs). Beyond identifying the best route between two network points, these distributed PoPs also enforce security controls based on the security technologies defined above. Processing data closer to the user at the nearest PoP minimizes the trombone effect and significantly cuts round-trip times.
By delivering both network and security capabilities at the network edge, SASE helps reduce latency for global employees by eliminating backhauling. Users simply connect to their nearest PoP for inspection instead of routing traffic back to a centralized network. Connecting users to the nearest PoP minimizes physical distance, generally speeding up access to SaaS and cloud resources.
Plus, the security features provided by VPNs, including encryption and authentication, are replaced by a low-latency SASE framework. For organizations that still rely on VPN technologies, solutions such as enterprise Remote Access VPN can be integrated into a broader SASE strategy to provide secure connectivity during migration phases. For example, ZTNA enforces continual authentication regardless of the user’s location. ZTNA also incorporates contextual information, such as device posture and behavioral patterns, to make risk-based determinations and provide granular access controls.
Deploying edge nodes to process data as close to the source as possible is critical for real-time applications like VoIP and video conferencing.
This offers security improvements compared to the broad network access provided by VPNs, reducing the attack surface and limiting lateral movement as part of a broader cybersecurity strategy.
Cloud services are at the heart of modern SASE architectures, enabling organizations to deliver secure access and robust security services to users wherever they are. By integrating secure web gateways, cloud access security brokers, zero trust network access, and firewall as a service into a unified, cloud-native platform, SASE empowers organizations to protect their cloud-based applications and sensitive data while maintaining optimal network performance.
SASE solutions enhance secure connectivity to cloud services by leveraging techniques such as caching, compression, and content delivery networks (CDNs). These optimizations reduce the physical distance between users and cloud applications, resulting in faster access and a seamless user experience. Whether employees are accessing resources on Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP), SASE ensures that security policies and trust network access controls are consistently enforced.
By providing seamless and secure connectivity to cloud services, SASE not only reduces latency but also simplifies network access management and strengthens the organization’s overall security posture. This integration of security and networking at the access service edge enables organizations to confidently embrace cloud transformation while safeguarding against evolving cyber threats.
Below are the key factors that enable SASE latency reduction for global employees. SASE not only optimizes network performance but also enhances operational efficiency and simplifies network management through centralized control, making it easier to administer, secure, and scale enterprise networks.
A cornerstone of SASE latency reduction is its global PoPs infrastructure. SASE vendors offer distributed PoPs strategically placed around the world to ensure that users always connect to the nearest edge node.
Each PoP performs security inspection, routing, and optimization locally, dramatically reducing the physical distance between users and the resources they need.
This edge cloud SASE architecture reduces round-trip times and ensures consistent SASE global performance (even if employees are working on the other side of the world from the main corporate headquarters).
Beyond eliminating unnecessary backhauling, SASE helps reduce latency for global employees by identifying the optimal path between two locations on the network. SASE SD-WAN technology continuously monitors multiple network paths and dynamically selects the best route for each session.
By utilizing real-time analytics, SD-WAN:
Ensures smoother traffic flows this provides low-latency SASE performance even when network conditions fluctuate.
Also, application-aware routing can prioritize an organization’s most critical applications while less important data is sent over alternative paths. This ensures the most important data always has the lowest latency.
Traditional VPNs typically route all data through a centralized network, resulting in bottlenecks during periods of high traffic. In contrast, ZTNA authenticates and connects users directly through the nearest PoP, reducing ZTNA latency and improving overall session responsiveness. By replacing legacy VPN models, ZTNA streamlines secure access and minimizes delay for remote employees.
Beyond ZTNA latency improvements, SASE also enables more granular access controls.
VPNs typically provide users with the same access as an on-site user. ZTNA enables access based on the principle of least privilege and contextual data. This enhances security, minimizing the impact of compromised credentials.
By eliminating the bottlenecks at centralized networks, edge cloud SASE architectures enable organizations to scale their global workforce.
With SASE latency reduction and bandwidth improvements, organizations have the infrastructure in place to handle the increased traffic demands of more workers in more locations. For example, new PoPs can be deployed or scaled dynamically to maintain low-latency SASE performance as the demands increase.
SASE Digital Experience Monitoring (DEM) capabilities help enterprises track SASE performance metrics and quantify latency improvements. Key metrics include:
By comparing these metrics before and after deployment, you can track SASE global performance and latency reductions. With this information, you can work with SASE vendors to fine-tune the implementation and ensure low-latency SASE connections for every global employee.
Edge computing is a powerful enabler within Secure Access Service Edge (SASE) frameworks, allowing organizations to process data and enforce security policies closer to where users and devices are located. By deploying edge computing nodes at the network edge, SASE architectures minimize the distance data must travel, significantly reducing latency and improving real-time application performance.
This approach alleviates the strain on centralized servers and helps prevent network congestion by streamlining data flow directly between users and the nearest edge node. Techniques such as data caching, content delivery networks (CDNs), and software-defined networking (SDN) further enhance the efficiency of edge computing in SASE environments. These technologies work together to optimize overall network performance, reduce delays, and ensure that security posture is maintained even as data moves rapidly across distributed environments.
Integrating edge computing with SASE solutions also enables real time threat detection and improved network visibility, empowering organizations to respond quickly to evolving threats while maintaining secure access and high performance for critical applications and services.
Caching and compression techniques are essential tools for optimizing network performance and reducing latency in Secure Access Service Edge (SASE) environments. By storing frequently accessed data closer to users—whether at the edge, in the cloud, or on local devices—caching dramatically decreases the time required to retrieve information, resulting in faster application response times and a smoother user experience.
Compression techniques complement caching by reducing the size of data packets transmitted across the network. This not only accelerates data transfers but also conserves bandwidth, which is especially valuable in environments with high network traffic or limited resources. In SASE deployments, these techniques are applied across cloud services, edge computing nodes, and network traffic flows to ensure that data moves efficiently and securely.
By leveraging caching and compression, organizations can optimize network performance, minimize latency, and provide secure access to applications and data—no matter where users are located. These strategies are key to delivering the high-performance, low-latency experience that modern enterprises demand from their access service edge SASE solutions.
SASE latency reduction offers significant business benefits, including faster application and cloud access, improved collaboration, increased productivity, and enhanced talent flexibility, allowing organizations to hire from a global talent pool rather than relying solely on local applicants. SASE also reduces operational complexity and enhances operational efficiency by consolidating networking and security functions into a unified platform.
But there are implementation challenges to achieving low-latency SASE global performance. These include:
To address these challenges, organizations should conduct comprehensive evaluations of SASE solutions, including independent measurements to accurately assess their impact on network response and performance. Evaluating the effect on both network performance and user experience is critical for successful implementation.
When selecting a SASE provider, best practices include considering how well the platform integrates with existing AI-powered next-generation firewalls and other core security controls:
SASE reduces costs by eliminating the need for on-premises hardware and streamlining vendor management. It provides visibility of hybrid enterprise network environments, including data centers, headquarters, branch and remote locations, and public and private clouds. SASE enhances threat monitoring and detection, streamlines network governance, and simplifies management. Its flexibility and scalability make it indispensable for protecting distributed resources in organizations. SASE allows organizations to embrace a zero-trust security strategy, further enhancing security against evolving cyber threats. By integrating comprehensive security services directly into the network fabric, SASE enables uniform management of security policies across the entire enterprise.
Despite these hurdles, the long-term benefits of SASE latency reduction make it a worthwhile investment for enterprises with distributed teams.
To maximize the benefits of Secure Access Service Edge (SASE) and ensure secure, high-performance connectivity, organizations should adopt a set of best practices tailored to today’s dynamic threat landscape and distributed work environments. Start by conducting comprehensive network assessments to identify potential vulnerabilities and performance bottlenecks. This foundational step enables IT teams to design a SASE architecture that aligns with business needs and security requirements.
Implement robust security measures such as zero trust network access, secure web gateways, and cloud access security brokers to defend against evolving cyber threats and ensure that only authorized users and devices can access sensitive data and applications. Continuous verification of user and device identities is essential for maintaining a strong security posture and supporting zero trust principles.
Regularly monitor network traffic and key performance metrics—including latency, jitter, and packet loss—to identify areas for improvement and fine-tune SASE solutions. Automated reporting and analytics can help IT teams quickly detect and respond to anomalies, ensuring that security measures remain effective and network performance stays optimized.
