ArcSight vs QRadar - Key Differences and Comparison

ArcSight and QRadar are the two well-known Security Identification and Event Management tools that support detecting threats in an environment and resolving them quickly. This blog will be a good choice for anyone interested in knowing the differences between these two. This blog will discuss the basic differences between ArcSight and QRadar, their features, pros and cons, and many more.

As you know, cyber-attacks would severely damage enterprises if the security systems are not appropriately managed. It is essential that we detect threats in the environment earlier before they could attack and harm data and other resources. In this way, ArcSight and QRadar are two well-known SIEM (Security Identification and Event Management) tools that provide effective threat control and protection to networks in the best possible ways.

This blog will compare the two technologies, ArcSight and QRadar, in terms of their various aspects, such as products, features, deployment, pricing, and benefits.

ArcSight Vs QRadar – Solutions Provided

ArcSight provides solutions for large-scale enterprises and mid-market companies of all types, including Energy, Financial Services, Healthcare, the Public Sector, Government Services, Telecommunications, and Transportation. In addition, ArcSight offers you various solutions such as advanced threat detection and response, people-centric attack mitigation, pre-emptive threat detection, and SecOps compliance.

On the other hand, QRadar provides security solutions to mid-market enterprises and small businesses as well. Computer and Network Security, IT and services, banking are the main sectors where QRadar can be leveraged. Specifically, QRadar helps you detect threats and remove them from networks as soon as possible. Aside from this, QRadar offers you a range of solutions such as cloud security, endpoint security, incident response, insider threats, network security, ransomware removal, threat hunting, and threat intelligence. According to a McKinsey survey, 50 % of the threats are made internally. In this way, QRadar is best to encounter internal threats.

ArcSight Vs QRadar – How can be they Deployed?

Can be deployed in the Cloud, SaaS, Web-based, and Desktop.

Can be deployed in the Cloud, Web-based, SaaS, Desktop for both Mac and Windows.

ArcSight Vs QRadar – Strategies Followed

1. ArcSight

  • Categorization and Normalisation: These processes just help you convert the security logs into a unified format. Therefore, it accelerates the process of identifying severe threats at the very beginning and resolving them.
  • Layered Analytics: It supports your SOC to detect threats before they can cause harm to networks. ArcSight combines three analytic solutions and forms a layered analytic, which will help to open up new insights and achieve holistic threat protection.
  • RTC Engine: The real-time advanced and multi-dimensional correlation engine achieves speedy threat detection and response through intelligent rules and dashboards.
  • Unsupervised ML: ArcSight implements unsupervised machine learning to identify insider threats and outside attacks. And the AI-enabled security analytics and UEBA (User and Entity Behaviour Analytics) support you to identify the elusive threats.

2. QRadar

  • Zero Trust: As per this strategy, QRadar generates alerts for threat detection by examining every single security log thoroughly. Not only does it detect threats, but it prioritizes them and acts on them.
  • Federated Search: According to this strategy, security solutions, end-point reduction, and security tools can be connected for analyzing data stored across various data sources. It helps you to uncover the hidden threats from the disparate data too.
  • Orchestration and Automation: With the support of automation tools and third-party integrations, threats are identified quickly and responded to quickly. So, it increases productivity and efficiency.
