What is Secure Access Service Edge (SASE)?

Secure Access Service Edge (SASE) systems is an architectural model that combines an array of security capabilities including WAN, firewalls, secure gateways, and zero-trust network access.

SASE consists of several products, whose goal is to allow users to access applications with the best possible user experience and the highest level of security, all depending on the user’s identity. Any user, regardless of their location, or asset should be able to access any application, either corporate or public, in a secure way. Versatility, scalability and user experience are of paramount importance.

What is Secure Access Service Edge (SASE)?

How It Works

SASE describes a change in architectural principles that moves away from a traditional on-premise data center and shifts to a decentralized architecture. When organizations adopt Secure Access Service Edge principles, they distribute user access to corporate resources instead of consolidating them in one place. SASE is an architectural methodology that converges network and security requirements into a single cloud-centric solution that allows cloud transformation.

It is an undeniable trend that more resources are moving from the traditional data center to the cloud. This is the reason why instead of routing traffic from branch offices and remote users to the data center, where the internet egress point was typically located, SASE recommends that users and branches should all have a direct internet breakout.

Key Features of a SASE Architecture

Adopting an SASE framework has many advantages for today’s businesses, the most important of which is how it helps adopters prioritize security, no matter what other tools they’re using. For example, if your business needs to change service providers, SASE platforms continue undisrupted. A SASE architecture is platform agnostic, enabling the most flexible security infrastructure possible. This flexibility also makes it easy for businesses to scale up their security infrastructure as they grow, without having to reconfigure the central architecture. The ability to customize security settings operational needs, enables companies to create an architecture to meet their current and evolving business needs. It is important to keep in mind the following security and network components of a SASE architecture.

Security

SD-WAN Security:

Companies that are dealing with a significant amount of legacy infrastructure in branch offices want to stop backhauling internet-bound traffic to the regional hub site, without having to upgrade the legacy gateways. With SASE, they can save WAN costs without compromising security.

Firewall as a Service (FWaaS):

A cloud-based Next-Generation Firewall is a scalable, application-aware solution allowing enterprises to eliminate the challenges of legacy appliance-based solutions.

Web Security:

Secures Internet access to Web applications and resources leveraging unified Threat Prevention solutions, such as URL Filtering, Anti-Virus, IPS, Anti-Bot, and Zero-Day attack prevention.

Browsing Protection:

A simple browser extension complements the cloud-based security controls and allows for full visibility into encrypted traffic, protecting against the loss of corporate data and mitigating modern-day malware such as ransomware, zero-day attacks, phishing, etc. so you can safely navigate today’s menacing threat landscape.

Secure Remote Access to Corporate Resources

Replacing traditional remote access solutions where the VPN was terminated in an on-premise Data Center, SASE Remote access no longer requires the traffic to be backhauled, improving the user experience.

SaaS Security:

Secure access to SaaS applications such as Office 365 and Google suite, using a Cloud Access Security Broker (CASB).

IoT Security

SASE enables IoT devices to break out to the internet directly in a secure way.

Network

SD-WAN:

Optimizes access to the Internet and Data Centers by allowing branch offices and users to break out to the Internet directly and securely, which significantly improves the user experience.

Essential Features:

Routing, dynamic path selection, NaaS, and latency optimization are all essential networking features of SD-WAN, laying the foundations on which security is built.

Reasons to Consider a SASE Architecture

When looking to adopt a SASE architecture for your company, there are several benefits to consider including: attaining cloud-centric technology, reducing the operational burden and cost, as well as improving security and reducing threats.
