Understand SASE

SASE (Secure Access Service Edge) is a cloud-based network security architecture that integrates networking and security functions into a unified service. Introduced by Gartner, SASE integrates technologies such as:

  • SD-WAN (Software-Defined Wide Area Network)

  • Secure Web Gateway (SWG)

  • Cloud Access Security Broker (CASB)

  • Firewall as a Service (FWaaS)

  • Zero Trust Network Access (ZTNA)


This unified approach enables secure, fast access to applications and data from anywhere, regardless of whether users are in the office, at home, or on the road. A true game changer for modern organisations.


Benefits of SASE for your company

  1. Enhanced Security

    • Centralized security policies.

    • Real-time threat detection and mitigation.

    • Zero Trust approach — users are authenticated continuously, reducing risk of breaches.

  2. Improved Performance

    • Direct-to-cloud access reduces latency.

    • Optimized routing improves user experience with cloud apps (like Microsoft 365, Salesforce).

  3. Reduced Complexity

    • Combines multiple security and networking tools under one platform.

    • Easier to manage and scale globally via a single dashboard.

  4. Scalability & Flexibility

    • Ideal for hybrid workforces and global teams.

    • No need for on-site infrastructure in new locations.

  5. Cost Efficiency

    • Shifts from CAPEX (hardware, licenses) to OPEX (subscription model).

    • Less need for on-prem IT staff to maintain complex hardware stacks.


Comparison: SASE vs. Traditional Hardware & VPN Services

Aspect

SASE

Traditional Hardware/VPN

Deployment Time

Fast (cloud-based, minimal setup)

Slow (procurement, setup, config of appliances)

Scalability

High (cloud native, auto-scale)

Low (hardware limits, VPN gateway bottlenecks)

User Experience

Optimized for cloud and remote access

Slower access, especially across regions

Security Posture

Unified, dynamic, Zero Trust

Siloed tools, static VPN access

Management Overhead

Low (single console, automation)

High (multiple systems, manual updates)

Cost Model

Predictable OPEX (subscription-based)

High CAPEX and ongoing maintenance

Support for Remote Work

Native and seamless

Clunky, requires VPN clients

In Summary


Potential Gains of Using SASE

  • Operational Efficiency: Centralized policy management and automated updates reduce IT workload.

  • Cost Savings: Avoid purchasing/refreshing firewalls, VPN concentrators, and MPLS links.

  • Risk Reduction: Consistent security controls across all access points, reducing attack surface.

  • Future-Readiness: Prepares companies for increasing cloud adoption and distributed workforces.


SASE modernizes and simplifies enterprise networking and security by delivering it from the cloud, with massive advantages over traditional hardware and VPN-based architectures — especially in a world where users and applications are increasingly distributed.
