As more than half (51 percent) of organizations are planning to increase their spending on cloud security, the current and future priorities are on incident response, threat detection, and proactive risk management. CASBs act as middlemen between the users and the cloud providers to ensure that the information is protected when organizations adopt cloud services.

As the threats related to cloud environments develop, it has become critical for companies to identify the most appropriate CASB providers to secure cloud applications and environments. In this article, we will look at the best CASB vendor for 2025, what they offer, their features, and how they can improve cloud security. Furthermore, we will also help you understand some important factors to consider when selecting the right CASB provider for your organization.

What is a CASB (Cloud Access Security Broker)?

A Cloud Access Security Broker is a security solution that stands between users and cloud apps and provides organizations with the ability to monitor and manage data flow, user actions, and access points. During Q2 of 2024, organizations experienced 1,636 cyber attacks per week which is a 30% increase compared to the previous year. CASBs are instrumental in protecting the organization from such risks by implementing security measures, identifying threats, preventing data leakage, and compliance with legal requirements.

CASBs provide detailed control over cloud services, which enable companies to fight against shadow IT, unauthorized access, and misconfiguration and, therefore, enhance their overall cloud protection.

The CASB solutions provide various functionalities, including DLP, encryption, identity management, and activity monitoring, to create a complete security shield for the cloud. With the increasing utilization of cloud services in the course of business operations, CASBs have proven to be vital in guarding assets and minimizing risks to threats.

Need for CASB Vendors

Businesses now turn to cloud applications in their operations, which may be from different vendors. This multi-cloud strategy may lead to a lack of visibility and non-compliance if not well-coordinated. CASB security vendors address these challenges by offering:

1. Comprehensive Visibility: CASB vendors offer full control over users and their actions and data in different cloud environments. This visibility enables the identification of unapproved applications in the cloud also referred to as shadow IT and monitor data flow to avoid loss. This means that security teams can detect anomalies as they happen and before they become big issues. This way, organizations can manage all their cloud activities in one place and, therefore, improve the cloud security posture.
2. Data Protection: The principal focus of CASB is to secure critical data. Vendors employ encryption, tokenization and rights management to protect data in storage and in motion. Through the use of granular policies, CASBs block downloads, and sharing or modification of information that is not supposed to be. This level of protection minimizes the chances of a data breach and guarantees that all assets are protected, whether in the cloud or not.
3. Threat Detection and Response: CASB vendors employ AI and behavioral analytics to identify abnormal behaviors that are indicative of insider threats or external attacks. CASBs work by recognizing trends in user behavior and then triggering predefined actions when such behavior is not observed. This is because by taking such measures, organizations are able to prevent threats from reaching the cloud environments. Threat detection tools also work in conjunction with other SIEM systems so that threats can be remedied more quickly and the risk in the cloud can be understood in more detail.
4. Compliance Management: There are various sectors that have to meet certain legal requirements, like HIPAA, PCI DSS, and GDPR. CASB vendors help in compliance by providing the means of automatically creating audit logs and compliance reports. Thus, it is possible to control all cloud activities and make sure that they meet the necessary regulatory standards. CASBs also offer policy templates that can be further adapted to suit certain compliance requirements of an organization. This helps in cutting down the amount of work that the IT departments have to do and also reduces the chances of penalties for non compliance.
5. Shadow IT Discovery: Shadow IT poses a great threat because it enables unauthorized applications to go through security measures. CASB vendors find and track unauthorized use of cloud services by employees. In this way, the analyzed services can be cataloged and either prohibited or at least subjected to the official IT governance. Shadow IT discovery allows to minimize the probability of data leaks, enforce policies and control the use of cloud services.
6. Access Control and Identity Management: Preventing unauthorized access to cloud applications is a function of managing who has access to them. CASB solutions implement RBAC and MFA to ensure that cloud resources are protected from unauthorized access. CASBs also work with identity providers to ensure that only the right people are allowed to access the data.
