What Is SASE Security and Why Do You Need It?
The numerous cyberattacks on networks require the use of multiple security systems to address individual threats. But as you deploy a ton of applications, you soon realize that managing them is a challenge in itself. It helps to have your security arsenal in one fold, readily available and accessible.
Secure Access Service Edge (SASE) offers you a unified security approach by combining the solutions you need into one cohesive system to ease your workload. You might be wondering what SASE is and how it works—here’s all you need to know.
What Is SASE?
Secure Access Service Edge (SASE) is a modern security architecture approach that offers various network andsecurity-as-a-service applicationsas a single cloud service. It provides an inclusive cloud-based security solution that secures your system and its users regardless of their location.
Safeguarding your system with security solutions like Software-Defined Wide Area Network (SD-WAN), Cloud Access Security Broker (CASB), Firewall as a Service (FWaaS), Secure Web Gateway (SWG), and Zero Trust Network Access (ZTNA) individually can be tasking, but SASE makes it easier by combining them into a single framework. Hence, you may access all your cloud-based applications in one fold without bothering about unauthorized access or data infringements.
How Does SASE Work?
Deployment is fundamental in cybersecurity. Even when you have strong defenses, they become ineffective if you can’t access them when the need arises. SASE puts your security at your fingertips, enabling you to reach for them quickly in the cloud from any location.
The primary goal of SASE is to supply you with a unified and effective security model that works for your system remotely. To accomplish this, it synchronizes multiple security measures, including FWaaS, ZTNA, and SWG into a single cloud-based platform.
Software-defined Wide Area Networks (SD-WAN)
SD-WAN gives your applications maximum security and unlimited network connection. It streamlines internet connectivity to reduce network congestion on your system and boost its performance.
With SD-WAN, your system can easily add another network layer on top of its existing connection. You can use this software to control and prioritize your network and make sure that your apps get enough bandwidth. It’s an easy way to connect all your networks over the internet in a safe and effective way.
Zero Trust Network Access (ZTNA)
Zero Trust Network Access (ZTNA)uses a first-privilege access model and controls data accessbased on the user credentials, devices, and the software they’re operating.
ZTNA offers your system security that focuses on the application by enforcing security rules for each session. This software works with cloud-native systems and gives you a more flexible way to protect your data. It has a centralized control panel that makes it easier for you to handle policies and plan a security strategy.
Firewall as a Service (FWaaS)
Firewall as a Service (FWaaS) is acloud-based security system that protects your network via a firewall. You can use FWaaS to establish firewall policies and rules in the cloud without having to deploy a physical firewall device. The goal of FWaaS is to offer your network a security solution that is scalable, adaptable, and inexpensive
FWaaS gives your network a safe perimeter. It also helps to enforce access regulations on your network, monitor traffic for threats, and stop unwanted access to your platform.
Secure Web Gateway (SWG)
Secure Web Gateway (SWG) is a security system that protects you from inappropriate material, using different measures like blocking you off harmful websites and preventing you from downloading malware unaware. It also provides you with the provision of URLs for filtering and content inspection. As a network security solution, it protects you from real-time online traffic and threats. SWGs aim to keep you safe from malware, phishing, and other forms of online harm.
Security features such as URL filtering, content inspection, and virus detection are commonly included in SWG solutions. Together, these functions will safeguard your system from all manner of online dangers as well as enforce policies that govern access to specific types of web content.
Cloud Access Security Broker (CASB)
The Cloud Access Security Broker (CASB) is a security tool for monitoring and managing your cloud-based resources. Data loss protection, malware detection, and user behavior analytics are just some of the services that a CASB may monitor and enforce in real time for all your cloud-based applications.
What Are the Benefits of SASE?
SASE is quite different from traditional network security—it gives your system safe access to fundamental network assets and protects it from a series of cyberattacks. Although SASE has several benefits, the core ones include the following.
Enhancing Security With Zero Trust
Enhanced security is one of SASE’s main advantages as it offers a thorough defense against a variety of threats including malware, phishing assaults, loss of data, and other sorts of cyberattacks. This is attainable when you combine multiple security measures such as ZTNA, CASB, FWaaS, and SWG.
SASEimplements a zero-trust security modelwhich states that all elements within your network are suspect until they prove themselves to be credible. Regardless of the user, device, or application, it examines all entities seeking access to your network, validating only the legitimate ones.
Simplifying Security Management
You can easily manage your networking and security infrastructure from a single interface, thanks to SASE’s cloud-native architecture. This method eliminates the complexity involved in controlling numerous devices across several locations and simplifies your network management.
Implementing patches and updates to individual applications can be tasking. There’s a tendency for you to miss some of those when dealing with siloed tools. Since SASE has all the applications in one place, it’s easier to keep an eye on them and perform the necessary updates when due.
Improving Network Performance
SASE offers you a safe and effective network connection between several sites through the use of SD-WAN. Hence, it guarantees that key applications receive the required bandwidth and performance because SD-WAN uses software to control and prioritize traffic.
SASE also provides a strong network connection and maintains operational continuity while minimizing downtime. Through the use of numerous network pathways, it creates backups that guarantee network connectivity even when you encounter a network failure.
Enhancing Remote Work
The ability to work remotely is no longer a luxury but a necessity today as more people embrace remote work. To get the most out of it, you need the right systems that won’t restrict you to a physical location. SASE offers a flexible framework that you can implement in your operations to meet your specific needs.
Security is a major concern for remote teams as someone could compromise the system either intentionally or unintentionally. SASE uses advanced technology that enables you to manage user input with effective access controls. If there’s a breach on one end, you can initiate a rapid incident response to prevent it from spreading across the entire system.
Reducing Costs
Acquiring and maintaining several applications can be expensive. Choosing a multipurpose cloud-based system such as SASE helps you cut down costs since the tools are in one package. You also get to save money on maintenance. Although SASE undergoes maintenance too, this is usually the responsibility of the service providers or vendors.
SASE also gives you access to a cloud-based subscription model that eradicates expensive licensing and maintenance costs.
Unify Multiple Security Solutions With SASE
SASE uses advanced security technologies including FWaaS, CASB, SWG, and ZTNA to safeguard your applications and data from dangers. It gives you access to a flexible and agile approach to network security, enabling you to scale your security services to meet your changing operational needs.
The cloud-based network security system offers you a cheaper way to protect your network by getting rid of hardware devices. It also simplifies managing your networking services.
Application security can secure your data and protect it from external threats like hackers.
