Secure Access Service Edge (SASE)

The Secure Access Service Edge (SASE) combines SD-WAN with security functions like SWG, CASB, FWaaS, and ZTNA into one service.

A SASE architecture integrates networking and security services, delivering them through the cloud at the edge of the network. This allows organizations to effortlessly connect remote and hybrid users to nearby cloud gateways instead of routing traffic to central data centers. The result is a reliable, secure access to all applications, with comprehensive traffic monitoring and analysis across all ports and protocols.

SASE’s main objectives are to simplify management and reduce complexity. It transforms the perimeter into a unified set of cloud-based capabilities that can be deployed wherever and whenever they are needed. Instead of using disparate, point-product security appliances to create a perimeter around the data center, this method is more efficient.

With secure access service edge, you can build a dynamic, high-performance network that adapts to changing business needs, evolving threat landscapes, and new innovations that will shape your network in the future.

With the SASE framework, various functions and capabilities are consolidated into minimal products and services from a small number of vendors. This approach enhances operational speed and simplifies management. To deploy secure access services on the edge, five essential technologies are required.

For user web sessions, the secure web gateway (SWG) provides URL filtering, SSL decryption, application control, and threat detection and prevention.

FWaaS (Firewall as a Service)

FWaaS provides advanced Layer 7 inspection, access control, threat detection and prevention, and other security services in the cloud.

A cloud-access security broker

In addition to monitoring sanctioned and unsanctioned SaaS applications, CASBs provide malware and threat detection as part of DLP solutions.

Zero Trust network access

An organization’s sensitive data and applications can be protected through zero trust network access (ZTNA). ZTNA enables continuous verification and inspection capabilities.

SD-WAN

A SD-WAN provides a flexible, secure network overlay that is decoupled from the underlying hardware, enabling flexible, direct internet connectivity between sites.

Hybrid environment visibility

The SASE provides visibility into hybrid enterprise network environments that link data centers, headquarters, branches, remote locations, public and private clouds, and users.

Users, data, and apps can all be viewed from a single pane of glass with consistent functionality and universal access from anywhere.

Control over users, data, and apps

Various applications are frequently accessed from multiple locations and devices, often bypassing organizational policies to run them on nonstandard ports, presenting a challenge in monitoring and controlling them.

However, SASE classifies traffic at the application layer, or Layer 7, eliminating the need for port-application research and mapping. It enables precise control and understanding of application usage.

Monitoring and reporting improved

Security access service edge eliminates the need to monitor multiple consoles across different networking and security products or to create separate reports for key metrics by eliminating the need to monitor multiple consoles across different networking and security products. Network and security teams can correlate events and alerts on one platform, which speeds up incident response and streamlines troubleshooting.

Complexity is reduced

Businesses can streamline networking and security with Secure Access Service Edge. By eliminating unnecessary, complex, and manual point security solutions, operations can now shift to the cloud. As a result, operational complexity and costs are significantly reduced. It also eliminates logistical challenges associated with dispatching, installing, and updating networking and security devices in branches and retail outlets.

Protection of data in a consistent manner

Traditional WAN architectures based on MPLS route traffic from numerous locations back to a central point. This design centralizes security by allowing a single firewall to enforce policies, but it potentially becomes a bottleneck.

It eliminates challenges such as security blind spots, policy inconsistencies, and shadow IT by prioritizing consistent data protection across all edge locations.

A secure access service edge deployment streamlines the deployment of security services and applications from the cloud to various locations by applying data loss prevention (DLP) policies uniformly regardless of the location of the data. Additionally, each endpoint does not need to be managed individually.

Cost reductions

Although commodity point networking and security products may seem less expensive initially, administrative costs can quickly escalate. Network and security staff with limited capabilities must learn different management consoles and operating systems (many of which are restricted in remote management).

In a cost-effective manner, SASE enables organizations to extend their networking and security stack to all locations.

Reduced administrative time and effort

The cost of training and retaining networking and security staff on many point networking and security products can quickly exceed initial capital investments. With SASE, networks and security functions can be managed consistent across all locations with a single pane-of-glass. By consolidating, administrative burden is reduced and training and retention costs are reduced.

Integration needs are reduced

SASE combines multiple networking and security capabilities in a unified cloud-delivered solution, eliminating the need for complex integrations between multiple point networking and security products.

Improved Network Performance and Reliability

Using software-defined wide area networking (SD-WAN), SASE improves network performance and reliability for users and locations. Multiple links from different sources, such as MPLS, broadband, and LTE, can be load balanced, aggregated, and failover configured in this way.

Using MPLS connections or routing traffic across a connection that’s experiencing high utilization or performance issues can reduce congestion and latency associated with backhauling internet traffic.

A better user experience

Without the complexity of installing additional hardware or software, digital experience monitoring (DEM) optimizes experiences for every user, whether they are working from home or from branch offices.

Challenges associated with SASE implementation

SASE is a relatively new cybersecurity model, but reputable vendors already have proven processes in place. Enterprises should not be dissuaded from investing in SASE even though potential obstacles may arise. When organizations are prepared with knowledge, they can overcome questions and challenges with ease.

Collaboration and team roles redefined

The implementation of SASE requires a re-evaluation of roles within the IT landscape. Particularly in hybrid cloud setups, it necessitates enhanced collaboration between networking and security teams. Particularly when distinct teams handle on-premises and cloud-based infrastructures at the same time, confluence of responsibilities can be challenging.

Managing Vendor Complexity

SASE combines various tools and methodologies, so organizations can more easily navigate the vendor landscape and adopt an architecture that aligns with their transformation objectives.

Coverage that is comprehensive

It is important to maintain a judicious balance between cloud-driven and on-premises strategies in order to ensure seamless networking and security, particularly in branch-heavy setups.

SASE Trust Building

In hybrid cloud scenarios, a segment of professionals remains wary of transitioning to SASE, despite its advanced capabilities. As a result, organizations should work with reputable SASE providers that have established credibility and can address both networking and security issues effectively.

Selection and integration of products

For businesses with siloed IT teams, deployment may involve selecting multiple products to cater to networking and security separately. Integrating these solutions, while ensuring they are complementary, is essential for smooth operations.

Sprawl of tools to be addressed

In order to ensure a cohesive technological infrastructure, it is crucial to identify any redundancies and mitigate potential overlaps before implementing a cloud-centric SASE paradigm.

SASE: A Collaborative Approach

Together, security and networking professionals ensure the selected SASE components align with the broader organizational objectives, optimizing the benefits derived from SASE.
