Businesses are always looking for new and innovative ways to secure their networks and data.
The ever-growing cyber security threats have led to the growth of a new type of security service known as Secure Access Service Edge (SASE).
According to Gartner, by 2025, more than 50% of organizations will have clear strategies for implementing SASE.
SASE is a cloud-based security service that provides perimeter security for businesses by protecting them from cyberattacks and data breaches.
With SASE, companies can control access to their networks and data centers through a secure, cloud-based platform.
This allows businesses to grant or deny access to specific users, devices, or applications, depending on their needs.
What Are The Core Security Components Of SASE?
Four core security components make up SASE solutions, which include:
Secure Web Gateway
Secure Web Gateway (SWG) is a crucial component of SASE that provides security for web traffic.
It includes features like web filtering, application control, and URL categorization to help organizations protect against malicious and inappropriate content.
Cloud Access Security Broker
Another core component of SASE is the Cloud Access Security Broker (CASB). It is a security solution between an organization and the cloud services they use.
CASBs provide visibility and control over data in the cloud, help to prevent data breaches, and can enforce compliance with corporate policies.
Zero Trust Network Access
Zero Trust Network Access (ZTNA) eliminates the need for predefined trust levels between users and systems. In a Zero Trust Network Access model, there is no trust.
Access is granted on a case-by-case basis after verifying the user’s identity and the context of their request.
This helps prevent unauthorized users from gaining access to sensitive resources.
Firewall As A Service
FWaaS is a cloud-based security service that provides perimeter security for SASE applications.
It uses a combination of firewalls, intrusion detection/prevention systems, and web application firewalls to protect the SASE environment from unauthorized access and attacks.
Reasons Why SASE Is The Latest Trend And The Future Of Network Security
The following are the reasons why more and more organizations are adopting the SASE model and why SASE is the latest trend and the future of network security:
1. Flexibility
SASE provides a high degree of flexibility in deploying and configuring network security.
This is because SASE is a cloud-based solution that can be easily scaled up or down to meet the changing needs of an organization.
SASE encompasses all capabilities needed to securely connect users to resources, including but not limited to ZTNA, SWG, CASB, DDoS, WAAP, and so on.
The integration of these services allows for a unified security posture that is more adaptable and responsive to changes in the underlying environment.
2. Increased Security
SASE offers increased security compared to traditional network security solutions.
It uses a multi-layered approach to security that includes firewalls, intrusion detection and prevention, and malware protection.
SASE protects against attacks from inside and outside the organization and can be set up to allow or deny access to specific resources based on user identity, location, time of day, or other criteria.
3. Improved Performance
SASE can improve the performance of an organization’s network by reducing the number of security devices that need to be deployed.
SASE is a new architecture that seeks to merge network and security functions into a single platform.
This can provide significant performance benefits, as processing data does not have to pass through multiple devices.
4. Lower Costs
SASE can help lower the costs of deploying and maintaining a network security infrastructure.
SASE is a cloud-based solution that eliminates the need for expensive on-premises hardware and software.
5. Greater Efficiency
SASE can improve the efficiency of an organization’s network security infrastructure.
This is because SASE automates many of the tasks associated with managing a network security solution, such as patch management and rule updates.
6. Simplicity
SASE is a simple solution that is easy to deploy and manage. This is because SASE is a cloud-based solution that does not require the installation of any on-premises hardware or software.
Conclusion
SASE is the future of network security. By combining different layers of security, you can create a more secure system that is difficult to penetrate.
While no system is perfect, SASE offers businesses the best possible chance to protect their data and networks.
Have you implemented SASE in your business? If not, now is the time to start thinking about how you can make this important change.
