SIEM vs CASB for Cloud Security and How Tufin Fits Into the Equation

Last updated July 27th, 2023 by Avigdor Book

In the realm of cybersecurity, every company seeks the most efficient and effective tools to safeguard their digital assets. Two prevalent solutions in the industry are Cloud Access Security Brokers (CASB) and Security Information and Event Management (SIEM). The debate around CASB vs SIEM can be intense, but this post will break it down for you, highlighting why you might lean towards SIEM, and where Tufin fits into this picture.

Understanding CASB and SIEM: An Overview

CASB, standing for Cloud Access Security Broker, operates as a gatekeeper, allowing organizations to extend their security policies to cloud services, whether it’s SaaS, IaaS, or PaaS. It helps control shadow IT, ensure data security, and manage granular access control.

On the other hand, SIEM (Security Information and Event Management) systems provide real-time analysis of security alerts by applications and network hardware. SIEM collects and aggregates log data generated throughout the organization’s technology infrastructure, from host systems and applications to network and security devices such as firewalls and antivirus filters.

A crucial difference between CASB and SIEM is their focal points. While CASB primarily focuses on securing cloud services, SIEM provides a comprehensive view of an organization’s information security, covering both on-premises and cloud environments.

So, the question is: Should you stick with CASB or lean more towards SIEM?

The Superiority of SIEM Over CASB

SIEM holds the upper hand over CASB in a few ways. For one, SIEMs offer a comprehensive perspective on both on-premises and cloud-based resources, providing real-time threat detection, threat intelligence, and cybersecurity event management. SIEM goes beyond cloud services to analyze data from other sources such as network devices, security systems, databases, and servers for threat protection.

On the other hand, CASB specializes in managing cloud services but lacks the same breadth of analysis offered by SIEM. It does not have the same capacity to detect vulnerabilities and security threats in other areas of your digital infrastructure.

This is not to downplay the value of CASB or to suggest that CASB is no longer necessary. Far from it! CASB is a powerful tool for managing cloud service providers, offering data loss prevention (DLP), identifying shadow IT, providing granular access control, and more. But if you need to choose between CASB and SIEM, your decision should hinge on your specific needs and the breadth of coverage you require.
