Cloud Access Security Brokers (CASBs) are growing in popularity as organizations rely on an increasing number of SaaS applications, and this popularity has led to a large number of CASB solutions now on the market. Below are factors to consider for CASB vendor comparison, and our list of the 5 top CASB solutions in 2025.
Cloud access security brokers sit between users and SaaS applications to monitor traffic and deliver a range of security controls. CASB integration enables organizations to adopt SaaS applications without incurring the risk associated with dispersing data across the cloud.
CASBs provide a range of functionality. Generally speaking, CASB use cases and capabilities can be grouped into four main pillars:
Listed below are key factors to consider when selecting an effective CASB solution.
There are two main deployment models: inline/proxy CASB and API CASB. While proxy CASB offers real-time monitoring and the ability to uncover shadow IT, API CASB offers enhanced visibility and security controls without increasing latency. The leading CASBs for 2025 typically employ a hybrid or multimode approach, combining technologies to leverage the benefits of both.
Top CASB solutions provide a range of security capabilities that can be grouped based on the four pillars discussed above:
When comparing the leading CASBs, prioritize solutions that offer robust security features across these pillars.
User experience and network performance are crucial factors to consider during CASB vendor comparison. Consider CASB tools that provide an intuitive and user-friendly interface for a better user experience, as well as solutions that don’t significantly impact latency for optimal network performance.
To avoid this, consider cloud-native platforms built on globally distributed infrastructure.
Scalability and adaptability ensure your investment in a new CASB solution continues to deliver value as your business evolves. Again, cloud-native solutions can help provide scalable and flexible CASB functionality to ensure your organization remains protected even as the demands on the technology change.
CASB integration determines how the solution fits into your existing infrastructure and monitors SaaS applications. CASBs should fit into a broader security posture. Combining with other tools to provide comprehensive network coverage and protection.
Top CASB solutions often come with integrations for commonly used SaaS applications, simplifying deployment.
Below is our list of the leading CASBs for 2025 based on the criteria discussed above.
Check Point’s CASB security solution maps your entire SaaS ecosystem, automates threat protections, and identifies security gaps to continually reduce your attack surface. Utilizing machine learning analysis to detect anomalous behavior and stop it before it escalates into a full attack, Check Point provides threat protection capabilities for zero-day attacks, as well as traditional signature-based identification methods.
With automatic SaaS discovery from Check Point, you can immediately identify new SaaS applications and understand their associated risk and compliance implications. This includes alerts and fast fixes if data falls outside of regulatory requirements.
Check Point CASB capabilities go beyond traditional SaaS Security Posture Management (SSPM) solutions to deliver instant discovery and fully automated threat prevention.
Check Point’s CASB functionality is part of the company’s broader Secure Access Service Edge (SASE) solution. Combining CASB technology with SASE reduces operational complexity, allowing organizations to manage their entire network from a single, unified dashboard.
A user-friendly cloud access security broker, Zscaler CASB provides visibility and in-depth security controls through a multimode deployment. Proxy architecture provides shadow IT discovery capabilities and real-time protection, while API integrations scan SaaS applications for enhanced control and the ability to secure data at rest.
SaaS applications are assigned an overall risk score, allowing Zscaler users to view and filter their services to develop security controls.
Tools for securing SaaS applications include tenancy restrictions, SSPM, User and Entity Behavior Analytics (UEBA), and more. Zscaler CASB is part of the Zscaler Data Protection solution alongside DLP functionalities. It is also one of the 6 core technologies that make up the company’s Zero Trust SASE solution.
Palo Alto Networks offers a next-generation CASB solution that focuses on centralized controls and simplified operations. This includes optimizing workflows through machine learning-based automations and simplified configuration.
With multimode deployment, Palo Alto’s CASB solution offers both inline and API security features as well as SSPM and DLP capabilities designed for enterprises.
Their technology scans all traffic, ports, and protocols to identify new apps (sanctioned and unsanctioned). API-based CASB technology also protects data stored on SaaS applications, ensuring that security settings are configured for optimal protection. Security features include enhanced visibility, control over SaaS usage, access policies, and protection against evolving threats.
Palo Alto’s CASB-X license is available through the company’s SASE platform (Primsa Access) and Next-Generation Firewall (NGFW).
Cisco’s CASB tools enable enhanced policy decision-making, prevent malware from spreading from SaaS applications, and limit data exfiltration when it leaves your on-premises infrastructure to be stored in the cloud. This includes detecting and remediating any malware present on sanctioned cloud storage applications, to prevent users from spreading it to your network.
Cisco CASB functionality includes protecting data in real-time using inline CASB and out-of-band data at rest using API integrations. The technology’s goal is to simplify employee access to approved SaaS applications while preventing the use of unsanctioned services.
These CASB capabilities are available as part of Cisco Umbrella, a cloud-delivered security service, and the company’s SSE and SASE platforms.
Netskope’s CASB delivers proactive and flexible security for organizations using SaaS applications. The cloud access security broker enables businesses to quickly identify and manage their entire SaaS landscape, including shadow IT. With deep visibility into cloud usage, organizations can track data being shared with SaaS applications and introduce safeguards for the unauthorized sharing of sensitive data with cloud-based apps.
The solution leverages AI to secure and categorize SaaS tools and prevent SaaS sprawl. Leveraging Gen-AI algorithms and large language models, Netskope automates these processes to streamline workflows and make CASB integration as easy as possible for IT teams.
The company’s CASB solution is a key component of Netskope One, a cloud-native SASE platform built on SSE components and zero-trust principles.
With industry-leading security features, minimal latency, cloud-based scalability, and simple integration, Check Point SASE meets all the criteria to differentiate itself from other top CASB solutions.
