How SASE Solutions Can Revolutionize Your Network Security

Elevate network performance and security while simplifying overall management with SASE solutions.

SASE combines various networking and security services into one comprehensive solution. This includes branch FWaaS, SD-WAN, ZTNA, CASB, DLP, and advanced threat protection.

This unified architecture reduces complexity, speeds IT agility, and fosters cross-functional conversations among networking, security, and systems administration teams.

Securing Data In The Cloud

Securing Data In The Cloud

Securely accessing internal systems is critical for an organization to function in today’s business climate. That is particularly true for remote users working outside of the corporate network. Unfortunately, legacy inspection and verification strategies that rely on forwarding remote user traffic to central firewalls for security checks or “hairpinning” the data in an MPLS network before reaching a corporate device are not only costly but can also create bottlenecks that reduce productivity and cause a poor end-user experience.

Effective SASE solutions combine SD-WAN capabilities with multiple network security functions delivered from a cloud platform. This approach unifies networking and security options, reducing complexity and management costs while achieving a least-privileged model and ensuring consistent policy enforcement.

Integrated SASE solutions include branch FWaaS, next-generation firewalls, CASB, DLP, and Zero Trust network access (ZTNA). These tools work together to provide a robust perimeter that protects centralized resources from external attacks – such as DDoS attacks, vulnerability exploits, and data theft – regardless of the device’s location or network connection.

When deploying an integrated SASE solution, the collaboration between networking and security teams is essential to ensure all aspects of the system are properly configured, managed, and tuned. It is crucial when implementing ZTNA, which requires the strict identification and verification of every device and user that attempts to access a private network.

Securing Edge Devices

The modern workplace includes a growing number of remote and mobile employees. By implementing SASE solutions, including SD-WAN and zero trust network access (ZTNA), you can securely access applications from anywhere, reduce costs, enhance reliability, and provide a great user experience.

By integrating security services into the network infrastructure, SASE reduces the need for third-party security products. This results in time savings and improved management. Plus, scalability provides an advantage, as you can quickly adapt to meet changing business requirements without needing hardware replacements.

Many SASE solutions are available on a service-based model. While this can make implementation more manageable and cost-effective, it does not guarantee scalability. Be sure that your chosen solution can handle your current and expected future traffic to ensure the system can scale as your company grows.

The best way to understand whether or not SASE is the right solution for your business is to talk with a partner that offers intelligent SD-WAN and SASE solutions.

Securing Data At The Point Of Presence

When SASE solutions are implemented, security is applied based on the device and its identity using real-time contextual information. This information is collected and analyzed at line speed by in-line engines like malware detection and sandboxing, as well as functions that continuously assess risk and trust during sessions.

SASE also eliminates the need for multiple separate hardware appliances and tools. It means lower equipment, software, and maintenance costs. It also reduces the number of vendors enterprises must work with and the hardware deployed in branch offices and remote locations.

Centralized control is maintained for network and security aspects that must remain in-house, such as setting policies. However, most of these capabilities are handled at distributed points of presence (PoPs) closer to end users. Restricting access to corporate resources reduces the attack surface.

A key feature of SASE is Zero Trust Network Access (ZTNA), which allows employees to securely access network and cloud resources from anywhere using any device. It is achieved by granting access based on identity instead of a device’s location or IP address. It provides granular visibility and control of which devices, users, and applications are accessing network services. It also increases performance by bypassing the need to send traffic for inspection to a central data center.

Securing Your Endpoints

Traditionally, network security solutions have been centralized in the data center and required rerouting remote user or device traffic back to headquarters for security inspection. This model has proved untenable with the rise of cloud services, software-as-a-service (SaaS), and distributed workforces. SASE solutions eliminate this reliance on a central point of control by consolidating networking and security functions into a single solution delivered in the cloud.

It includes SD-WAN, CASB, FWaaS, and Zero Trust security solutions, all within a single integrated service stack positioned near the endpoint. Remote users and branch offices can connect directly to cloud services without bypassing the primary firewall.

Another critical component of SASE is an intrusion prevention system that protects endpoints against malicious attacks by analyzing traffic for abnormal patterns or behavior. It also detects and filters DNS queries that could expose a company’s internal servers to malware attacks or data exfiltration.

Before making a final decision to adopt SASE, your organization must perform a thorough assessment of its existing infrastructure and security setup. Then, you can identify and understand what objectives you want to achieve by adopting SASE. It will help ensure a smooth integration that supports your business goals and provides the best possible outcome for your organization.
