By unifying these elements, SASE aims to streamline network management and boost security.

SASE platforms combine several important security and networking technologies. These work together to protect data and provide secure access across distributed networks.

Zero Trust Network Access (ZTNA)
ZTNA is a core part of SASE. It checks users, devices, and apps every time they try to access network resources. This helps stop threats from both inside and outside the network.

Web Traffic Filtering
SASE includes tools to filter web content and block risky online behavior. This helps prevent cyber threats and protect sensitive data as employees browse the internet.

Cloud App Security
As more companies use cloud services, keeping data safe becomes harder. SASE platforms have features to control and monitor cloud app usage. This gives IT teams better visibility into cloud-based tools.

Network Connectivity
SASE uses advanced networking to connect offices and other sites:

Advanced Firewalls
SASE incorporates next-gen firewalls that do more than basic ones. They can:

Some SASE systems may also include:

SASE brings these tools together in one package. This helps companies:

Key features of SASE include:

SASE platforms often use multi-factor authentication to verify users. They may also check device health before allowing access.

By combining networking and security, SASE aims to:

As cyber threats grow more complex, SASE offers a way for businesses to stay protected. It helps secure both office and remote workers, no matter where they connect from.

SASE platforms offer many benefits for modern organizations. They boost security by using Zero Trust principles . This means users must prove who they are before accessing data, even if they’re on the company network. SASE looks at things like where users are, what device they’re using, and company rules to decide if access is okay.

SASE helps save money by combining many security tools into one cloud service. This means fewer vendors to deal with and less time spent trying to make different products work together.

It makes IT work easier and faster. Teams can set and change security rules for all locations, users, devices, and apps from one place. This helps fix problems more quickly.

SASE improves how people work from anywhere. It finds the fastest network path based on traffic. This means less waiting for remote workers.

Here are some more ways SASE helps:

SASE brings together networking and security. This makes it easier to spot threats and fill in security gaps. It also makes running the network simpler, which is great for companies with people working in different places.

SASE offers several key benefits for modern businesses. It helps improve access to resources and network connections. By using a global cloud network, SASE can process data closer to users. This cuts down on delays and makes work smoother for people in different places.

SASE is great for companies with hybrid workforces . It allows staff to work from anywhere while keeping data safe. This setup works well for full-time employees, short-term workers, and outside partners.

Security is a big plus with SASE. It applies the same safety rules to all users, no matter where they are. SASE checks all network traffic, which helps stop many types of attacks. These include:

SASE also helps with data rules. It can see all network requests and apply the right policies. This helps businesses follow data privacy laws.

For companies with many offices, SASE makes things easier. It can replace old systems and link different sites. This makes it simpler to send data between offices.

SASE is changing how businesses handle remote work . It’s moving away from old VPN systems to a more flexible approach. This new method lets people use work tools from any place, while keeping everything secure.

With SASE, companies can better manage who sees what. This is great for working with outside helpers without giving them too much access. It keeps company secrets safe while still letting work get done.

SASE and SSE are two network security models that have gained traction in recent years. While they share some similarities, they have key differences in scope and focus.

SASE takes a comprehensive approach to network security and connectivity. It combines networking functions like SD-WAN with security services in a unified cloud-based framework. The goal is to provide secure, optimized access to all organizational resources.

SSE, on the other hand, narrows its focus to cloud-centric security services. It leaves out the networking aspects that SASE includes. SSE aims to secure access to web, cloud, and private applications without addressing network connectivity itself.

Both models typically include these core security capabilities:

Some key differences between SASE and SSE:

SSE can be seen as a subset of SASE focused purely on security. Some organizations may choose to start with SSE and potentially expand to full SASE later on.

Beyond the core capabilities, some SASE and SSE platforms offer additional features:

Organizations may choose between SASE and SSE based on their needs and existing infrastructure. Those with established SD-WAN setups might opt for SSE to enhance security without changing their networking. Others may prefer SASE for a fully integrated approach.
