Cloud Access Security Broker (or CASB) sits between organization users and cloud service providers and monitors the network traffic for enforcing companies' security policies.
CASB solutions can be implemented both cloud-based or on-premise. In addition, they extend security across Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Integration-as-a-Service (IaaS).
Cloud access security brokers help businesses fight against security threats and keep the cloud data safe. It follows a three-step discovery, classification, and remediation process to secure cloud platforms.
The general working principle is this: first, it compiles cloud-service usage; then, it classifies these into different risk categories; after analyzing the relative risks of these cloud services, CASB sets policy for data and user access as per the organizational security guidelines and enforces the same.
When looking for CASB software, make sure it satisfies the following requirements-
Offers real-time visibility: Companies with large manpower find it challenging to keep a tab on all the cloud services being used and who is using them. Most cloud service providers do not offer a proper logging or data audit in their normal plan tiers. However, an ideal CASB software provides businesses complete visibility into their cloud app usage. This helps discover any redundancies.
Optimum data security features: Undoubtedly, this should be a high priority while choosing a CASB solution for your business. All CASB software solutions come with an integrated cloud DLP (Data Loss Prevention Mechanism) system. It uses document fingerprinting, in combination with detecting the user's location and activity, to find any suspected violations.
Ensure security compliance: While moving on to the cloud, businesses must adhere to all security guidelines. These standards act as a base for secure cloud space, which can lead to data breaches. It addresses various compliance regulations, including HIPAA, GDPR, and regulatory requirements like PCI DSS, ISO 27001, and others.
Protection against security threats: Many times, third-party companies (or insiders) try to steal data or get access to sensitive information, which can lead to security threats. A robust CASB tool runs regular scans to determine cloud usage patterns. This way, if anyone attempts to steal the cloud’s data, they would get caught.
Moving forward, we will discuss the top 15 CASB solutions that you can opt to safeguard your cloud space.

Though CASB solutions are a good solution for securing platform as a service (PaaS) and infrastructure as a service (IaaS) platforms, for software as a service (SaaS), Zluri, a SaaS management platform, has advantages over CASBs:
Remote-first approach: CASBs primarily filter the data through logs (network packets, firewall, secure web gateways, endpoints) via deep packet inspection (DPI). Though this might work in the office environment, where the data can be controlled by flowing through the determined network, this is not enough for today's modern remote world.
Users can now access applications on the internet without going through a specific network. Furthermore, the logs are never exhaustive in nature. On the other hand, Zluri being connected to the source—the application itself, never misses any data, and the accuracy is high too.
Integration: Zluri has deep integrations with 400+ applications, including SSO (a few CASB and SIEM integrations including MCAS are under development), along with browser and desktop agents. We ensure to discover all the applications fully—both approved and unapproved (shadow IT) apps used by an employee.
Multiple sources: To provide 100% coverage, Zluri has multiple sources of information. We prefer to get the data directly from the application, including the usage and access data for each employee across multiple devices and multiple network connections. This is our preferred source of truth.
Another source of data is the point of source; hence we focused a lot on the browser extensions and desktop agents. These are optional f0r the users. Though we can also get the activity and usage data of applications used on the device, we don't send out any data over the network via our desktop agents.
The third option is to get the data via connected systems like SSO, CASB, SWG, finance and expense management systems, etc., which gives us a secondary source of information on the usage and activity to discover the applications.
5. Application coverage: We can discover SaaS apps with a massive portfolio of 160,000 known applications that keep on expanding at a much faster rate as new apps hit the market. Because of the multi-source approach, we can also help companies discover the internal applications and track the usage and activity.
This number is ten times more than MCAS's catalog, a CASB solution! In addition, with our 400+ deep direct integrations with applications, you get a plethora of information on the number of licenses, type of access being shared, security scopes, insecure connections, billing cycles, important metrics, etc., apart from just the access and usage data.
Zluri is built for the modern world where users can use any device, and we shall get information across each one of them since we do have a lot of agentless sources (with direct integrations on SSO and applications).
