SASE vs. CASB: Which is the Suitable Security Solution?

With the shift to hybrid work, organizations face new challenges. Fortunately, cloud-based technologies like Secure Access Service Edge (SASE) and Cloud Access Security Broker (CASB) are here to help. Comparing SASE vs CASB will help you choose the right one for your organization.

As businesses adapt to new ways of working, the need for flexible and reliable security solutions becomes crucial. Without the right tools, managing and protecting data across various locations and devices can be overwhelming. This can lead to security gaps and potential breaches.

In this article, we will compare SASE and CASB. By understanding the strengths and differences of these technologies, you can choose the most suitable security solution for your organization. This will help you enhance your network security and ensure seamless protection in a hybrid work setting.

But first let’s discuss SASE and CASB in detail.

What is SASE?

Secure access service edge, or SASE, is a cloud-based IT architecture that combines software-defined networking and network security tasks and delivers them from a single service provider. This model combines numerous network technologies and provides them as a service.

It integrates network and security capabilities into a single platform. It allows enterprises to provide both security and access to the users and data. SASE accomplishes this regardless of location, all while preserving visibility into network activity and control.

SASE solutions allow your team to connect to a single secure cloud network offered as a service, allowing them to access both physical and virtual resources.

The technologies, ZTNA, CASB, SWG, etc., are not new, but the convergence of these solutions in one product offering and single point of control is.

SASE offers a more comprehensive and adaptable solution for business networking and multilayered protection for enterprises. A network redesign and the retirement of outdated networking and security technologies may be necessary to use SASE.

SASE makes IT infrastructure easier to manage, update, and maintain by reducing the number of security products your IT team has to keep track of.

Unique Features of SASE

• Integrated Security and Networking: SASE combines network and security functions, making it easier to manage both aspects from a single platform. This integrated approach streamlines operations for your team, reducing complexity.
• Cloud-native Architecture: SASE leverages cloud-based technology, allowing your security team to scale up or down quickly, adapting to the organization's changing needs without costly hardware investments. This flexibility is a game-changer.
• Zero Trust Security: SASE enforces the zero-trust model, ensuring that every user and device is continuously authenticated and authorized. You can easily control who accesses what, meeting your security requirements.
• User-Centric Approach: It focuses on the user's experience, providing secure access to applications and data from anywhere. This is particularly beneficial in today's remote work environments.
• Global Points of Presence: SASE offers a distributed network of points of presence (PoPs) worldwide, improving performance and reliability for remote users. Your IT security team can ensure a consistent user experience, regardless of location.
• Cost Savings: By replacing the need for on-premises appliances and complex VPNs, SASE can reduce operational and infrastructure costs, a significant advantage for IT managers aiming to optimize budgets.

What is a CASB?

Initially, the focus of CASBs was on cloud visibility. This made it possible for businesses to find out about shadow IT. However, CASBs have expanded their offerings to include various features: visibility, compliance, threat protection, and data security.

CASB software can be hosted on-premises or in the cloud, and they are responsible for enforcing compliance, security, and regulatory safeguards across data and cloud applications.

The cloud access security broker (CASB) is becoming essential to the enterprise security stack.

Unique Features of CASB

• Shadow IT Discovery: CASBs can identify and manage unsanctioned cloud services used within the organization. Your team gains better control and can safeguard security risks associated with unauthorized applications.
• Data Loss Prevention (DLP): CASBs offer robust DLP features that allow your IT team to set policies for data sharing, preventing sensitive information from being accidentally or maliciously exposed.
• Real-time Visibility: CASBs monitor cloud application usage and data transfers. You can stay informed about what's happening in the cloud environment, which is crucial for security and compliance.
• Adaptive Access Controls: CASBs enable adaptive, context-aware access controls. This means that the level of access granted to users depends on various factors, such as location, device, and behavior, enhancing security.
• Compliance and Governance: CASBs help you ensure compliance with regulations like GDPR or HIPAA by providing audit trails, compliance reports, and policy enforcement tools for cloud services.
• Threat Protection: Many CASBs offer advanced threat protection, including detection and response to cloud-specific threats, which is especially important given the increasing number of cyber threats targeting cloud services.

After learning the unique features of SASE and CASB, let’s explore the various other factors to compare SASE vs CASB.
