Secure Access Service Edge (SASE) combines several security and networking functions to help protect corporate networks, data, systems, and applications while increasing their operational performance and saving costs.
In the modern era, maximum applications live outside the data center, and many cloud services have sensitive information. Not to mention, businesses seek to grow rapidly using various cloud-based systems and deal with massive data.
In addition, the distributed workforce is becoming prominent across the globe, where users connect from any device from anywhere, extending or blurring perimeters. Therefore, securing a network is essential for every organization.
However, traditional security systems like physical firewalls may not offer consistent and robust security due to current security demands and increased cybercrimes.
To this, SASE seems to offer advanced capabilities to protect your data and systems no matter where you work from using what device. This is why businesses from various industry verticals are leveraging this technology.
In this article, I'll discuss SASE, how it can help SMBs, and the best SASE solutions you can consider.
What Is SASE?
Secure Access Service Edge (SASE) is a cloud-based security technology to deliver security controls and wide area network (WAN) directly to the connection source such as a device, user, edge computing device, internet of things (IoT) device, branch office, etc., instead of using a data center.
The term “SASE” was coined in 2019 by Gartner, a technological research and advisory firm. It combines network security functions with software-defined wide-area networking (SD-WAN), delivering them using only one service provider.
SASE offers enhanced visibility and better control of an organization's traffic, users, and data access in and out of its network. It is vital for modern organizations distributed globally for scalability and smooth remote work, connecting offices and employees working anywhere with any device.
How Does SASE Work?
In SASE, security works on digital identity, regulatory compliance, company policies, and in a real-time context. Digital identity could be given to any user or device, cloud service, IoT system, application, and so on.
Since SASE combines SD-WAN capabilities with several network security functions delivered from a cloud platform, it offers many advantages. SASE allows an organization's employees to securely connect, authenticate, and access internal services from any location or device. This way, organizations can better control their data and traffic entering and leaving their network.
There are four main components of SASE:
#1. Cloud Access Security Broker (CASB)
Due to the increasing need to move systems to SaaS applications, methods like authorization, authentication, and secure access controls have become essential. This is where CASB helps.
For cloud-hosted services, A CASB executes various security functions such as:
- Revealing unauthorized corporate applications and systems
- Ensuring regulatory compliance by implementing consistent data privacy policies
- Protecting sensitive data through data loss prevention (DLP) and access controls
#2. Secure Web Gateways (SWG)
Modern businesses run in a distributed environment, not confined to a specific perimeter. Employees, contractors, freelancers, vendors, etc., may work from anywhere using any device or system. They may also need to access various resources, but it may involve security risks from malicious sites, and even an internal user may try exposing your sensitive data.
To this, SWG can help protect your network, data, systems, and applications from such instances. Its capabilities encrypt traffic in the cloud and work alongside other network security systems to:
- Enforce security policies
- Manage security effectively
- Prevent cyber risks by filtering harmful content from your web traffic and blocking malicious users
#3. Zero-Trust Network Access (ZTNA)
In the age of cybersecurity, you can't really trust anyone whether they work for your organization or outside it. Threats can come from all directions and even within your own team!
Hence, trust no one when it comes to your data, systems, applications, and other assets. This is what the concept of Zero Trust entails.
ZTNA solutions hide internal resources from external or public view in order to protect your systems, data, and applications from cybersecurity risks such as data breaches. For this, it requires real-time authorization for every device and user when they try accessing an organizational asset, trusting no one.
#4. Firewall-as-a-Service (FWaaS)
In today's distributed workforce environment, computing resources and users are both located at the network edge. In order to protect them, a cloud-based and flexible firewall or FWaaS is needed. It can support a growing number of IoT devices and edge computing demands.
FWaaS constitutes security capabilities like URL filtering, policy management, intrusion prevention, etc., unlike traditional firewalls. This way, it becomes easy for you to manage network security, spot incidences quickly, make changes, and set firm policies. It helps protect your cloud-based applications, platforms, and infrastructure.
Why Do Organizations Need SASE Solutions?
Conventional security methods were good at securing users, devices, and systems inside a network perimeter.
However, the corporate network is expanding and moving to the cloud. A distributed workforce is prevailing, and employees are working remotely from across the globe using any device and system.
Hence, there is a need to employ advanced technologies that can secure your data, users, devices, and systems no matter where they are located. You also need stronger access controls and threat protection mechanisms to fight sophisticated cyber attackers looking for weakness in your networks and systems.
In addition, backhauling the entire WAN traffic for security to data centers over a long distance creates network latency, especially in distributed workforce scenarios.
To this, technologies like SASE seem to be helpful. So, let's discover how beneficial SASE solutions are for SMBs.
SASE offers consistent security through a single cloud-based service for WAN connections and security functions. It uses a universal set of rules, policies, and security functions for every access session irrespective of users, devices, applications, or destinations.
In addition, SASE works on the Zero Trust model to grant access to data and applications only after a user or device has been authorized. Its CASB and FWaaS components help mitigate internal attacks and external threats, such as DDoS attacks, protecting both cloud-based and on-premise systems. They also filter URLs, incoming and outgoing traffic, and DNS queries to prevent data exposure, malware, and other threats.
Using a single vendor and cloud model for your network security functions and WAN reduces complexity compared to using multiple security systems from different vendors for different locations. It also streamlines the inspection of traffic using a single policy engine.
SASE reduces latency by routing your network traffic throughout the global edge network processing the traffic closer to the user. It optimizes routing and lets you determine a faster network path according to factors like network congestion. It is also advantageous for latency-sensitive collaboration applications, VolP systems, and videos.
Cloud-based services can save your expenses by shifting up-front capital investment to monthly subscriptions or pay-as-you-go. It also reduces the maintenance needs for SMBs as they can leave everything to the vendor for updates, patches, and security checks. All this significantly saves money, effort, and time.
Secure and Fast Access
SASE offers fast, secure, and consistent access to applications, systems, and networks for users and devices from any location and any device. In addition, implementing SASE in your organization is also easy, with fewer agents and apps for devices.
Now, here are our best SASE solutions to protect corporate networks for SMBs.
