Secure Access Service Edge (SASE) is changing networking as we know it. This advanced networking solution supports your team in and out of the office, ensuring they can seamlessly and securely access resources care of cloud-delivered Software-Defined Wide Area Network (SD-WAN) and security tools.
SD-WAN enables the efficient routing of traffic across several locations and optimises performance for services, while the SASE framework’s security functions include Secure Web Gateways (SWG), Firewall-as-a-Service (FWaaS), intrusion prevention systems, and Zero Trust Network Access (ZTNA) to provide a robust level of protection for users.
Today, we’re looking at what SASE is, how it works, and how it can help to enhance connectivity, performance, and security while supporting scalability to accommodate future growth for your business.
What are the Core Components of SASE?
SASE solutions can be broken down into a range of components. This includes:
- SD-WAN – This helps to route data and optimise network traffic.
- ZTNA – This ensures only users who have been authenticated have access to different resources.
- FWaaS – This provides threat detection and access filtration.
- SWG – This filters incoming website traffic to keep users safe.
How SASE Works
SASE solutions are cloud-delivered and distributed through the global network of Points of Presence (PoP). Traffic from users is routed through the SD-WAN component, and then directed to the closest PoP. When the traffic reaches this point, several security measures are carried out, as the data is inspected, filtered, and finally authorised. This is done to meet the organisational security protocols in place, and because this is centralised businesses can control and maintain consistent policies across the network.
What are the Benefits of SASE?
- Simplified network management, merging a range of point products into one solution and reducing the need to maintain on-site hardware.
- Improved scalability to support business growth, thanks to cloud-based tools.
- Enhanced security for every user to reduce risk.
- Better network performance, so your team can stay productive whether they’re in the office or working remotely.
Let’s take a closer look at how this advanced networking solution can build your cyber resilience and support distributed workforces below.
Enhance Cyber Security
As threats including phishing, ransomware, and data breaches become more common and sophisticated, SASE has a critical role to play. Zero Trust security frameworks and a cloud-based approach provide businesses with a more proactive way to defend themselves against the latest threats. ZTNA ensures access to resources is granted based on user verification rather than assuming trust should be given based on location, or the network being used. By verifying the identity of not just users, but their devices too, it becomes possible to monitor traffic for any anomalies while applying security measures in real-time. As a result, SASE can minimise vulnerabilities while ensuring security is always maintained regardless of where the user or their data is coming from.
Support Remote Workforces
The rise of remote work and hybrid work environments has helped speed up the adoption of SASE. Traditional network models, which rely on securing a centralised perimeter, are not effective if your team have access to corporate resources from several devices or locations. SASE addresses this by enabling consistent and secure access to several applications. With the integration of cloud security, SASE ensures that remote workers have the same level of security as those working on-site. It’s the way forward for businesses who want to scale and evolve without compromising security, performance, or efficiency.
