In the era of hybrid work and the need for fast and secure data access, organizations can no longer rely on traditional security systems. Secure Access Service Edge atau SASE (dibaca: “sassy”) hadir sebagai solusi modern untuk memenuhi kebutuhan jaringan dan keamanan yang terintegrasi.
But, what exactly is Secure Access Service Edge (SASE), what are its benefits, and can it really replace traditional VPNs and firewalls? Let's discuss them in full.
Apa Itu Secure Access Service Edge (SASE)?
Secure Access Service Edge (SASE) is a cloud-based security architecture that combines wide area network technologies such as SD-WAN with various network security features. These include:
- Secure Web Gateway (SWG)
- Cloud Access Security Broker (CASB)
- Zero Trust Network Access (ZTNA)
- Firewall as a Service (FWaaS)
Secure Access Service Edge brings together network and security services in one cloud-native framework, allowing enterprises to manage connectivity and security from one centralized point.
Unlike traditional solutions that rely on On-premise data Centers, SASE enables access and data management from anywhere—whether for office employees, remote, or from mobile devices.

Main components of SASE
Secure Access Service Edge terdiri dari dua pilar utama:
1. Networking (SD-WAN)
SD-WAN allows organizations to connect various locations (branch offices, factories, etc.) through a vast network that is managed intelligently and efficiently. This technology replaces expensive MPLS connections with more cost-effective and flexible internet connectivity.
2. Security as a Service
Includes the following features:
- SWG: Filter and control web access to prevent access to malicious sites.
- CASB: Provides visibility and control over the use of cloud services such as Google Workspace, Microsoft 365, and others.
- ZTNA: Replace VPN traditional with a zero trust approach to ensure only trusted users and devices get access.
- FWaaS: A cloud Firewall that can filter network traffic without the need for physical devices.
By combining these functions, Secure Access Service Edge delivers a holistic approach to networking and security.
Manfaat Secure Access Service Edge (SASE)
Mengadopsi Secure Access Service Edge membawa banyak keuntungan, terutama bagi organisasi yang mulai bertransformasi ke arah digital dan cloud-based operations.
1. Higher security and consistency
Because all connections—whether from headquarters, branches, or remote employees-go through a single cloud security framework, organizations can implement uniform security policies across networks.
2. Unlimited Scalability
SASE is designed to be cloud-based, which means it can be easily scaled to keep up with business growth without investing heavily in physical infrastructure.
3. Centralized and efficient management
One dashboard to manage all aspects of network and security allows IT teams to save time and effort.
4. Faster Global access
With globally distributed access points, users can quickly and securely access company resources from anywhere.
5. Reduce Operating Costs
Eliminates the need for hardware (such as physical firewalls and MPLS routers), and reduces the complexity of network management.
6. Support Hybrid Working Model
SASE is perfect for the era of remote and hybrid work because it supports secure access to applications and data from multiple locations and devices.

Is SASE replacing traditional VPNs and firewalls?
Secure Access Service Edge tidak hanya menggantikan fungsi VPN dan firewall, but also perfecting it.
1. SASE vs VPN
Traditional VPNs establish an encrypted connection from the user to the internal network, but:
- It often slows down access because all traffic has to be routed through a single point.
- Not designed for large scale use or remote employees.
- Does not provide sufficient segmentation or visibility of user activity.
SASE, with Zero Trust Network Access (ZTNA), offering a different approach:
- Only grant access to certain apps or data as per user requirements.
- Use layered authentication and device verification.
- Provides more granular and identity-based control.
2. SASE vs Firewall Tradisional
Conventional firewalls filter traffic at the physical network border. Disadvantages:
- Not effective for cloud and hybrid environments.
- Requires physical configuration and maintenance.
- Hard to scale.
SASE melalui Firewall as a Service (FWaaS) menawarkan:
- Filter traffic from the cloud.
- Security policies that can be applied globally.
- Direct integration with other security features such as CASB and SWG.
In other words, SASE is an evolution from traditional security systems to a more adaptive and flexible cloud-native model.
When is it time to switch to SASE?
Not all organizations should immediately switch to Secure Access service Edge, but there are signs that your system is ready or in need of migration, including:
- The number of remote users increased sharply.
- You start adopting SaaS applications on a large scale.
- The network infrastructure is spread over many locations.
- You have difficulty managing multiple security devices from different vendors.
If you experience some of the above conditions, then considering SASE is a strategic step for long-term efficiency and safety.
SASE use case studies
1. Multinational Companies
Companies with branch offices in different countries need a secure and well-managed network. SASE allows them to connect all branches without expensive local infrastructure.
2. Tech Startups
Startups with fully remote teams can use SASE to provide secure access to internal systems without building a VPN.
3. Educational Institutions
SASE enables access control to learning systems and student data in a more flexible and secure way.
SASE implementation challenges
Like any new technology, SASE also has its challenges:
- Migration from the old system: Moving away from traditional architecture requires careful planning.
- Vendor selection: Not all vendors offer complete SASE services.
- Policy adjustments: Organizations need to reset security policies to fit the SASE model.
However, with the right IT partner, all of these challenges can be managed well.
