Transformative Security, Designed for Performance

In a world increasingly shaped by cloud and mobile technologies, Epsilon’s solution, powered by leading SASE partners, ensures secure, swift, and localised connections to enhance user experiences.

SASE supports every facet of your network, from on-premises data centres to branch offices, cloud environments, and remote mobile users, thereby improving the security and efficiency of your global network. Experience an optimised, low-latency network across all network edges including remote user and homeworkers with SASE’s scalable, cloud-based architecture, agile enough to meet your ever-changing business needs. 


Security Service Edge (SSE), a cybersecurity concept introduced by Gartner, safeguards access to the web, cloud, SaaS services, and private applications. Delivered primarily as a cloud-based service, SSE may include on-premises or agent-based components. This approach empowers enterprise IT to rapidly address evolving business and security requirements such as cloud migration, adoption of public cloud applications, and facilitating remote work. 

Zero Trust Network Access (ZTNA)

ZTNA is an adaptive trust model that enables secure access to internal applications for remote users

Cloud Access Security Broker (CASB)

CASB combines multiple security policies that help ensure cloud application security across authorised and unauthorised applications, as well as managed and unmanaged devices

Secure Web Gateway (SWG)

SWG is a security solution that secures access to the internet and protects users against malicious online threats 

Firewall as a Service - SASE

Firewall as a Service (FWaaS)

FWaaS is a network security technology that delivers advanced Layer 7 or next-generation firewall capabilities from the cloud

Still wondering how SASE will benefit your enterprise? Get a glimpse of how Epsilon can help you navigate and simplify the process of securing your network as you accelerate digital transformation efforts. 

Scalability Made Easy

Looking to seamlessly expand your network while ensuring security and performance? 

SASE offers a cloud-delivered model that adapts to the evolving needs of your distributed workforce. It simplifies the process of scaling your business, network, and security together, providing agility and security in one package. 

Internet of Things (IoT) Integration

Want to harness the power of the Internet of Things (IoT) for your business? 

As IoT adoption grows, SASE steps in to provide a robust platform. Its exceptional connectivity and security features empower you to build a resilient IoT ecosystem that aligns with your business goals. 

Remote Work Enablement

Supporting a mobile workforce scattered across the globe?

SASE acknowledges the shift in work dynamics and the dissolving concept of a “trusted perimeter”. While legacy architectures and solutions like VPNs provide secure network connectivity to entire networks, ZTNA solutions (agent-based or agentless access) offer more granular access control to specific applications or resources based on user identity and contextual factors.

Cybersecurity Reinforcement

Searching for a robust and cost-effective security solution for your organisation? 

In a world where resilient connections are paramount, SASE steps up to deliver superior security that is both affordable and easy to manage. It equips your security teams to tackle advanced threats from any source effectively. 

Edge Application Support

Working with edge-native applications demanding high bandwidth and low latency? 

SASE’s edge-native framework guarantees low-latency and secure connectivity. This is crucial for supporting applications that rely on high bandwidth and low latency, ensuring an optimised user experience.

Frequently Asked Questions

1. What is Secure Access Service Edge (SASE)?

Secure Access Service Edge (SASE), dubbed “the future of network security” by Gartner, is a comprehensive cloud-based security framework that combines network security and wide area networking (WAN) capabilities into a single integrated solution. It provides secure and scalable access to applications and data for users, regardless of their location, while reducing the complexity and cost of traditional network and security infrastructures. SASE is designed to meet the needs of today’s distributed and mobile workforce by offering a cloud-native approach to network and security services.

2. What are the benefits of using Secure Access Service Edge (SASE)?

Adopting SASE offers a multitude of benefits that modern organisations find indispensable. It enhances security by integrating various security services into one platform, optimising network performance, simplifying management through a centralised console, lowering costs, and offering scalability for organisations of all sizes. 

3. Why deploy SASE instead of other security solutions?

The key difference between SASE and other point solutions or secure networking strategies is that it is both secure and direct. It is a better option for protecting distributed workforces and data in the cloud. Traffic from users’ devices is inspected at a nearby Point of Presence (PoP) and sent back to its destination, providing more efficient access to applications and data.

4. What is the difference between Secure Access Service Edge (SASE) and Secure Service Edge (SSE)?

Secure Access Service Edge (SASE) takes on a more comprehensive approach, focusing on both optimisation of user experience and network security. Secure Service Edge (SSE) is a subset of the SASE framework – it fundamentally focuses on unifying all security services such as Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), and Zero Trust Network Access (ZTNA), emphasising the need for a SASE cloud platform. The SASE framework includes SSE and SD WAN.

5. What is the difference between Zero Trust Network Access (ZTNA) and Virtual Private Network (VPN)?

VPN lacks the flexibility and visibility; once users are granted access to the corporate network, they can access anything on the network, leading to security gaps and policy enforcement issues. ZTNA provides secure remote access to applications based on an adaptive trust model, where defined access is required. 

6. How does Secure Access Service Edge (SASE) address the needs of remote and mobile workers?

SASE is well-suited to meet the needs of remote and mobile workers. It follows a robust zero-trust security model, allowing secure access from anywhere on any device while maintaining low latency. SASE also provides granular policy-based control, ensuring that remote workers have the right level of access based on their identity, device, and context. It easily scales to accommodate evolving remote workforces, making it an ideal solution for secure and efficient resource access for remote and mobile workers.
