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
Enhanced Security
Centralized security policies.
Real-time threat detection and mitigation.
Zero Trust approach — users are authenticated continuously, reducing risk of breaches.
Improved Performance
Direct-to-cloud access reduces latency.
Optimized routing improves user experience with cloud apps (like Microsoft 365, Salesforce).
Reduced Complexity
Combines multiple security and networking tools under one platform.
Easier to manage and scale globally via a single dashboard.
Scalability & Flexibility
Ideal for hybrid workforces and global teams.
No need for on-site infrastructure in new locations.
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.
