CASBs are cloud access security solutions that enable businesses to monitor, govern, and secure the usage of cloud applications. CASBs are also helpful in simplifying the regulatory landscape and protecting sensitive data from outside threats. The cost of using a CASB can vary widely, with some providers charging as little as $15 per user while others charge upwards of $85 per user per year.
Cloud Access Security Brokers
A cloud access security broker solution is an enterprise-grade cybersecurity solution that allows businesses to leverage the cloud safely while maintaining complete visibility over corporate data. The CASB can detect malware and ransomware attacks. Once activated, the Cloud Access Security Broker will alert the cloud security team of any activity that may require further investigation. R
It Monitors and Governs the Usage of Cloud Applications
A CASB provides deeper visibility into an organization’s cloud environment. It helps protect against cyber-attacks by monitoring cloud users and applications and enforcing a policy. With this new technology, organizations can ensure that sensitive data is protected and that no one outside the organization can access it. In addition, a CASB solution eliminates many overhead issues that cloud administrators face, allowing them to focus on more important matters.
CASB solutions use an auto-discovery feature to identify third-party cloud services deployed by the organization. Users can then be identified and assessed for their level of risk. The story of the threat that a cloud application poses to an organization is based on how sensitive the data is and what kind of data the user may be accessing. The CASB solution also allows organizations to grant different employee access levels based on their job functions.
It Simplifies the Regulatory Environment
Cloud service providers have increasingly implemented CASB solutions as a part of their overall security strategy. These solutions can help simplify the regulatory environment by detecting potential breaches of privacy and security regulations. In addition, to streamline the compliance process, CASB can help organizations bring shadow IT into the light and enable necessary work practices that protect the enterprise. For example, several CASBs advertise encryption and tokenization features. While these features are increasingly common in mainstream services, they were mainly motivated by analyst ratings and discovered that cryptography is a complex technical domain. Moreover, cryptography systems require much subject matter expertise not included in the CASB’s core competencies.
CASBs integrate with an organization’s existing IT management (IAM) tools to provide comprehensive visibility into the access landscape and risks. They closely watch the activity across cloud-based services, alerting IAM tools when new devices enter the network and communicating the credentials used to gain access. This visibility helps IAM assess access levels and block privileged accounts that unauthorized employees may use. By monitoring access to cloud services and cloud-based applications, CASBs simplify the regulatory environment.
It Protects Data from Outside Threats
CASBs can protect sensitive data and minimize the risk of data leakage. Because any technology is susceptible to outside and insider threats, it is essential to use a CASB to protect data from external and insider threats. These sophisticated systems monitor and analyze user behavior, blocking access to unauthorized locations and detecting irregular activity. They also offer malware protection mechanisms. By limiting the number of malicious files and emails, CASBs can protect sensitive data from outside threats.
CASB solutions can be integrated into many cloud applications and control how users access sensitive data. The main functions of a CASB solution include identifying and mitigating threats, managing access across different applications, monitoring and logging, and tokenization. With these functions, CASBs can enforce enterprise security policies and monitor risky behaviors, reducing costs and improving agility. In addition, for large enterprises, CASB solutions should be easy to deploy.
It Integrates with NGFWs
CASB is a cloud security platform that combines application detection and reporting with policy enforcement. Organizations use it to implement granular data security and privacy policies across all cloud-based devices, including unmanaged smartphones and IoT devices. It also helps organizations use cloud services more efficiently and effectively while maintaining data security and privacy standards. Besides protecting corporate assets, CASB also offers unified user authentication and traffic management features.
The CASB integrates with many firewalls, including NGFWs. Its advanced analytics engine detects account compromise and combines contextual data and user behavior analytics to protect data. It supports SAML and other authentication systems and enforces download DLP. It can also integrate with SIEMs and UBA/UEBA.
It Automates the Management of Data Policy Violations
Today’s organizations must prioritize regulatory compliance. However, maintaining compliance with privacy regulations can be complicated, especially in an ever-evolving threat landscape. To simplify this process, CASBs can provide a centralized database of data policy violations and automated compliance management tools. These tools can give insight into user activity and data manipulation. They also help organizations stay in compliance with privacy rules and regulations.
The architecture of CASB systems varies. For example, some are on-premises hardware, while others are cloud-based. Depending on your needs, the type of CASB you need will determine its capabilities and deployment model. For example, some CASB systems implement proxy-based security, which controls a predefined set of devices. However, proxy-based methods can be ineffective for Shadow IT, as they are limited in monitoring devices.
