Many businesses are harvesting the benefits of employing SASE  solutions in their enterprise networks. As predicted by Gartner analysts,  IT action-takers in organizations are deploying the SASE framework to simplify and centralize network and security management while saving costs.

During the COVID lockdown, companies scampered for solutions to sustain business activities and have their employees working from home while retaining high network security.

Some quickly found VPN software helpful, but many companies struggled with malicious activities, threats, and attacks of diverse kinds on their networks.

The complexity of today’s environment, which encompasses different on-site and cloud-native locations connected to diverse cybersecurity solutions, has turned out clunky and costly.

Since SASE’s introduction in 2019, there has been an increasing awakening of organizations in its adoption. Most companies today are concerned about routing, firewalls, quality of service, and service availability, a provision SASE has made room for.

Google trackers are lurking on 75% of websites. Cover your tracks to protect yourself.


And instead of businesses deploying, maintaining, and paying separately for the infrastructure, a service provider performs it as a cloud service.

What Is SASE Exactly?

SASE means Secure Access Service Edge, a cloud-native remedy for tackling network security problems. It incorporates different security components into a single, whole, and more effective system.

Some of SASE’s key components are Zero Trust Network Access (ZTNA), Cloud Access Security Broker (CASB), Firewall-as-a-Service (FWaaS), Secure Web Gateways (SWG), Next-Generation Firewall (NGFW), and WAN services such as Software-Defined WAN (SD-WAN) and other vital security services.

The combination of these brilliant resources helps to instate adequate, secure access to networks across different locations. And a vital feature of this model is being the ability to recognize users and devices on a Wide Area Network and provide access based on security protocols irrespective of where a potential user is found.

With technological advancement, the entrepreneurial world becomes more productive. The professional sector also experiences coordinated environments for efficiency and improvement, including public and private sectors.

The cloud-based system works better than the traditional system when data and information are reserved on hard drives alone. As a result, it is now undoubtedly a gold mine for IT teams and entrepreneurs in the network security environment.

Characteristics Of SASE Solutions

SASE is a cloud-delivery architecture. It integrates security and network features to provide efficiency, ubiquity, multitenancy, and scalability to users or applications from any location. 

Notice: Hackers create fake WiFi hotspots to steal your passwords when you log in to public WiFi. Secure your data.


SASE is Identity-driven. It grants access to users and devices based on identity authentication for each access request and access based per session.

SASE is policy-driven. It provides consistently delivered security policy enforcement regardless of where the device, resource, or user is located.

SASE provides detailed visibility data and user control, applications, and risks. It also utilizes Artificial Intelligence and Machine Learning, enables Continuous Diagnostics and Mitigation (CDM), and advanced risk assessments and analytics. And monitors often risks by assessing activities on the network consistently.

Major SASE Use Cases

1. Network Expansion Geared Towards Business Success

One of the SASE use cases by NordLayer is that network expansion is geared toward business success. SASE SD-WAN helps to scale seamlessly to meet up with the dynamic nature of the organizational needs, enabling managers to form simplified multi-cloud environments. These environments have centralized controls that are suitable substitutes for older mpls-based routing.

SASE is a modern security solution that helps companies connect to remote workers and contractors or securely migrate data storage devices and applications. Managers can also add or remove users based on their activity on network groups.

It also helps security teams manage user identities and privileges and trim workloads by automating onboarding and off-boarding. This process creates granular user control and streamlined security management.

2. Steady Security For Mobile Networks

With remote working becoming a growing system across organizations globally to boost efficiency and flexibility while reducing the cost of office operations and maintaining expensive facilities, SASE integrates security solutions to ensure safe operations between organizations and their remote workforce.

Remote work can create a high-security risk to a company, including data loss, malware, and theft. However, features such as key revocation make it possible to neutralize stolen devices so that the thief will find it impossible to access cloud data and services.

In addition, other security measures may be implemented, such as adding extra anti-phishing protection and blocking personal email accounts.

SASE offers speed and reduces latency for remote connections to enterprise applications through secure web gateways, web proxies, cloud-native next-generation firewall tools, and replicating office environments. IPsec tunnels narrow the threat surface with data encryption as the data is transferred from remote devices to a cloud data center, boosting the workforce’s efficiency.

3. Real-Time Behaviour Monitoring To Prevent Malicious Intrusions

Cloud systems are usually prone to attacks via credential theft, malware, poor network security, insider threats, or other activities that could compromise sensitive data or compliance strategies.

SASE merges diverse features, including Zero Trust to combat critical security risks. Profile management at the network edge will additionally reduce the risks of unauthenticated access through sign-on and multilayered authentication processes.

The software can also be used to monitor the number of log-in attempts and locations to uncover any malicious activity. When users have access to the SD-WAN, their activity on the system is tracked, and the monitoring systems track and send alerts when a breach occurs.

4. Real-Time And Historical Cloud Data Visibility

SASE adoption helps to create advanced cloud data visibility. Solutions such as monitoring tools to locate cloud apps and prevent potential threats. Also, data discovery tools can help to scan historical data that may pose a security risk to the network.

Cloud Security Posture Management (CSPM) helps company managers to keep their antivirus capabilities updated and block out threats. In addition, SASE offers security teams the opportunity to stage measured and controlled transition to cloud resources while also assuring coverage of all threat surfaces during transitional periods.

SASE adoption is definite in many organizations. And while only a few companies have been shown to make the dive into SASE architecture. It is simple, more efficient, and cost-effective.

Since it offers a wide array of security solutions that can save lots of money, improve efficiency, and foster simplicity, you can easily infuse a lot of security benefits into our network by leveraging the SASE solution.
