Inroduction to Cloud Access Security Broker Services
Many security-conscious organizations already have CASB, or Cloud Security Broker services, implemented in their security environment. With the increased adoption of cloud-based technologies both for work and at home, having a strong cloud security portfolio is critical. A CASB works to protect important data stored in the cloud that traditional solutions such as firewalls or web gateways do not by extending visibility and control into the cloud.
When an organization implements cloud security brokers services the CASB works to secure data that flows between the in-house network and the cloud environment, applying the same security policies to both places. The CASB can protect your data in the cloud from being visible to outside parties, preventing threats such as malware.
Four Pillars of Cloud Access Security Services
Without proper cloud security tools, your organization has little control and visibility of the data that you store in the cloud. CASB will identify when high-risk data is leaving the organization’s network. It allows you to see what actions are being performed in the cloud both on sanctioned apps and unsanctioned apps (Shadow IT).
Shadow IT are cloud services that are managed outside of the organization without the knowledge of the IT department. When implementing cloud access security services, your organization can discover these cloud services and begin to gain visibility into them. Oftentimes, IT departments discover that Shadow IT was 10 times more prevalent than they initially expected once they implement CASB. By gaining visibility into cloud services that were initially invisible, your organization is better protected against cyber-attacks.
Organizations are increasingly storing their confidential data in the cloud. Maintaining security in the cloud is critical to maintaining compliance with industry standards such as PCI DSS, HIPAA, or NIST 800-171. In recent years, there has been an increase in cyberattacks on organizations in all industries. In return, compliance requirements are being strengthened.
Organizations now must achieve greater security to protect their customer data, organizational data, and maintain compliance. A CASB works to extend security policies to the cloud, better-protecting organizations, and achieving compliance. The threats of being in non-compliance with industry standards are costly fines, a security breach, and loss of customer trust.
The cloud makes it easier for users to share data with the wrong people, potentially causing data to be lost or put in the wrong hands. Traditional data loss prevention tools (DLP) can be integrated into CASB in order to stop data leakage in the cloud. A traditional DLP product will not identify unauthorized sharing of cloud data, but when an organization utilizes Cloud Access Security Broker services, this visibility and control will be gained.
Employees or third parties with stolen passwords can be a threat to an organization. This can occur even if your employees do not have malicious intent. A CASB is able to track regular behaviors and usage patterns and therefore will detect abnormal activity. Cloud Access Security Broker services work to protect against threats in the cloud and can use these threat intelligence tools to prevent malware.
As with all security solutions, implementing Cloud Access Security Broker services is not a foolproof way of being 100% secure. As more organizations are migrating to the cloud, the next step of cloud security has been demanded. Secure Access Service Edge, or SASE, is that next step.
With the rise in the number of remote users within many organizations and the increased use of software-as-a-service (SaaS) solutions, the need for a new approach has grown direr. A SASE is a combination of wide-area networking (WAN), CASB, and Zero trust into a singular framework. Secure Access Service Edge (SASE) goes beyond current security solutions by combining networking and SaaS capabilities.

The architecture allows you to enable connectivity for users that are working remotely while maintaining security capabilities that enforce your organization’s security policies. SASE goes beyond CASB solutions to enable organizations to securely connect any user on any device from anywhere.
Implementing a SASE compliant framework is increasingly critical today as organizations adopt more cloud-based infrastructure. Achieving a SASE compliant framework isn’t just implementing one solution but is a combination of several solutions. For organizations, this can mean deploying DLP, a CASB, or securing mobile entities.
