Cloud Access Security Broker vs. Secure Access Service Edge
What's the Difference?
Cloud Access Security Broker (CASB) and Secure Access Service Edge (SASE) are both technologies designed to enhance security in cloud environments. CASBs provide visibility and control over data and applications in the cloud, helping organizations enforce security policies and prevent data breaches. On the other hand, SASE integrates network security and wide-area networking capabilities into a single cloud-based service, offering a more comprehensive approach to securing cloud access. While CASBs focus on securing cloud applications and data, SASE provides a more holistic solution that includes network security and connectivity. Ultimately, both technologies play a crucial role in protecting organizations from cyber threats in the cloud.
Comparison
Attribute | Cloud Access Security Broker | Secure Access Service Edge |
---|---|---|
Definition | Security solution that sits between an organization's on-premises infrastructure and a cloud provider's infrastructure to enforce security policies | Converged security solution that combines network security functions with wide area networking capabilities to support the dynamic secure access needs of organizations |
Deployment | Typically deployed as a standalone security solution | Integrated into a broader network and security architecture |
Focus | Primarily focused on securing access to cloud applications and services | Focuses on providing secure access to applications and services regardless of their location |
Functionality | Provides visibility, data security, threat protection, and compliance capabilities for cloud environments | Integrates network security, secure web gateway, firewall, and zero trust network access capabilities |

Introduction
Cloud Access Security Broker (CASB) and Secure Access Service Edge (SASE) are two technologies that have gained popularity in recent years due to the increasing need for secure access to cloud applications and data. While both aim to provide security for cloud environments, they have distinct attributes that set them apart. In this article, we will compare the key features of CASB and SASE to help organizations understand which solution may be best suited for their needs.
Definition
CASB is a security solution that acts as a gatekeeper between an organization's on-premises infrastructure and cloud services. It helps organizations enforce security policies, monitor user activity, and protect data in cloud applications. On the other hand, SASE is a more comprehensive security framework that combines network security functions with wide-area networking capabilities to provide secure access to cloud services and applications from any location.
Deployment
CASB solutions are typically deployed as software or hardware appliances within an organization's network. They can also be offered as cloud-based services, allowing organizations to protect cloud applications and data without the need for on-premises infrastructure. In contrast, SASE is a cloud-native solution that is delivered as a service from the cloud. This makes it easier to deploy and manage, especially for organizations with distributed workforces or multiple branch offices.
Security Capabilities
CASB solutions offer a range of security capabilities, including data loss prevention, encryption, access control, and threat detection. They can help organizations secure cloud applications and data by enforcing policies based on user behavior, device type, and location. SASE, on the other hand, provides a more holistic approach to security by integrating network security functions such as secure web gateways, firewall as a service, and zero trust network access. This allows organizations to secure their entire network infrastructure, not just cloud applications.
Scalability
One of the key advantages of SASE over CASB is its scalability. SASE solutions are designed to scale with the needs of the organization, allowing them to support a large number of users and devices across multiple locations. This makes SASE ideal for organizations with a global presence or those that are rapidly expanding. CASB solutions, on the other hand, may struggle to scale to meet the demands of larger organizations, especially if they have complex network architectures or multiple cloud providers.
Integration
Both CASB and SASE solutions can integrate with existing security tools and platforms to provide a more comprehensive security posture. CASB solutions often integrate with identity and access management systems, SIEM solutions, and cloud security platforms to provide a unified view of security across the organization. SASE solutions, on the other hand, can integrate with SD-WAN solutions, secure web gateways, and firewall as a service to provide a seamless and secure network infrastructure.
Cost
When it comes to cost, CASB solutions are typically priced based on the number of users or devices being protected, as well as the features and capabilities included in the solution. This can make CASB solutions more expensive for organizations with a large number of users or complex security requirements. SASE solutions, on the other hand, are often priced based on usage or consumption, making them more cost-effective for organizations that need to scale their security infrastructure quickly and efficiently.
Conclusion
In conclusion, both CASB and SASE offer valuable security capabilities for organizations looking to secure their cloud environments. While CASB solutions are well-suited for organizations that need to protect specific cloud applications and data, SASE provides a more comprehensive security framework that can secure an organization's entire network infrastructure. Ultimately, the choice between CASB and SASE will depend on the organization's specific security requirements, budget constraints, and scalability needs.
