The Ultimate Guide to SASE

The purpose of Secure Access Service Edge (SASE) is to enhance the security of devices on wide area networks by functioning as a cloud-based service that connects directly to the source of the connection rather than relying on traditional data center-based infrastructure. According to the statistical data, over 6 million data records were exposed globally through data breaches during the first quarter of 2023.

With companies increasingly using data, devices, applications, and services outside their network infrastructure, security, and risk management must go beyond the traditional network perimeter. Implementing a SASE solution for your business can improve your organization’s network flexibility and security. Let’s find out more!

Introduction to SASE

The term SASE (Secure Access Service Edge) was created by Gartner in 2019 to offer an advanced, more modern cybersecurity unified management architecture. Consisting of the materialization of network and security convergence, it offers protection more suited to the needs of companies against virtual attacks.

To achieve this, SASE makes security services closer to users, adapting based on the level of risk presented at the time. Regardless of where the user is, SASE can ensure consistent application of security controls without requiring backhaul of network traffic back to another location.

The Core Components of SASE Architecture

The SASE architecture consists of several fundamental components that offer extensive security protections and networking capabilities. Here are some of the SASE’s core components:

Web Security Getaways (SWG)
Cloud Access Security Brokers (CASB)
Zero-trust network access

Domain Name System (DNS)
Data Loss Prevention (DLP)
Firewall as a Service (FWaaS)

Why Every Business Should Consider Adopting SASE

SASE is a cloud-based approach that integrates networking and security capabilities into a single-service, globally distributed architecture that switches the security focus from traffic-flow-centric to identity-centric. Here are some reasons why business owners should think about implementing a SASE solution for their business:

Increased Efficiency

A cloud-based security infrastructure reduces friction by increasing network protection without degrading performance. Companies also become capable of the security gaps by implementing enterprise-grade security and providing various network security functions and services.

Examples include threat prevention, web filtering, limited footprint, credential theft prevention, DNS security, data loss prevention, company network name, and advanced firewall policies and networking tools.

Reducing Costs and Complexities

With SASE, everything can be concentrated on a single platform instead of purchasing and managing several point security solutions. This feature, without a doubt, drastically reduces costs, as it requires fewer IT resources.

It is possible to simplify IT infrastructure, reduce the number of security products, and consolidate an entirely cloud-based security model now. All this without compromising network performance, consistent security, and increasing your visibility. It is worth remembering that the best SASE solutions must come from only one supplier.

Security

The SASE model provides security and access controls much closer to the end user for internal cloud resources, such as:

Websites

Applications
APIs

This contributes to a better overall security posture for organizations with remote users, making it more difficult for malicious actors or hackers to exploit vulnerabilities. Knowing that these people use all possible means to attack a network and generate losses, SASE plays a fundamental role in threat protection.

Performance Increase

As applications and services move to the cloud, traditional corporate network and architecture becomes increasingly less efficient. Because traffic destined for the internet first passes through the data center and the corporate firewall before reaching its destination, the user experience ends up compromised.

With latency-optimized routing, SASE’s cloud infrastructure enables easy connection, reliable connectivity, and protection wherever your resources and remote workers are.

Comparing SASE with Traditional Network Security Solutions

SASE has changed the paradigm of traditional network security solutions. SASE is cloud-native and offers agility and scalability through cloud services for networking and security. In contrast, traditional solutions sometimes rely on hardware installed on-site, resulting in extended implementation times, increased maintenance costs, and constrained scalability.

Additionally, SD-WAN integration with SASE enables optimal, secure connections among dispersed locations and remote connections, whereas traditional installations may call for several WAN management systems.

In addition, SASE offers strong visibility and analytics that enable real-time monitoring and threat identification, whereas traditional systems might not deliver the same level of real-time insights.

Key Benefits of Implementing SASE for Modern Businesses

The SASE security concept consolidates diverse networking and security functions into a single integrated cloud, service provider, and powerful security provider.

In this way, it prevents companies from looking for isolated solutions for each of their network security needs. Regarding data protection, the SASE structure is highly efficient in preventing unauthorized remote access, data access and hijacking of confidential information.

Reduced Complexity

Various security features, including branch office access control Firewall as a Service (FWaaS), Secure Web Gateway, ZTNA, CASB, and advanced threat intelligence and prevention features, can be combined.

Flexibility and Best Performance

SASE is platform-independent, allowing the security infrastructure to be much more flexible. Users will have a more fluid experience in various tasks, such as connecting to cloud SaaS applications and web conferencing.

Scenario Optimization

Network As A Service should preferably come from the same supplier, consolidating its solutions so that the costs and complexity of the scenario are reduced. This optimization also encompasses communications network latency and other crucial factors. Such as the organization’s operational overload and the constant need to acquire new technological solutions to keep up with the evolution of threats or the organization’s growth;

The Future of Cybersecurity: Predictions and Role of SASE

SASE is anticipated to play an important role in shaping the future of cybersecurity, which is quickly evolving. Here are several predictions emerging threats and the role of SASE in the future of cybersecurity:

Convergence of Security Capabilities

Businesses will increasingly use security platforms that provide a converged set of security capabilities in a single architecture, enabling security teams to more efficiently secure corporate networks, protect users, protect assets, and safeguard complex infrastructures.

Security Simplification

The trend of security simplicity will gain traction, lowering the complexity and lack of interoperability of traditional approaches that frequently require several vendors and services to perform the same control.

Faster Adoption of SASE

SASE is anticipated to gain popularity more quickly because it offers a flexible, agile, and cloud-based approach to network security that can assist companies in staying ahead of emerging cyber threats while minimizing complexity and costs.

Conclusion

SASE is a cloud-based technology that combines network and security operations into one user-friendly service. Instead of just doing network connectivity and focusing on how data flows, it emphasizes protecting data by examining who is attempting to access it. Businesses that use a SASE solution for your business can increase their internet connections’ performance, security, and flexibility while saving money.
