What is Security Information and Event Management (SIEM)?

SIEM (Security Information and Event Management) products analyze security alerts issued by applications and network hardware in real-time. This term serves as an umbrella for a variety of security software products, including Log Management Systems, Security Information Management, Security Log/Event Management, and Security Event Correlation. These features are often combined to provide 360-degree security and protection. Although a SIEM framework isn’t perfect, it is one of the most important indicators that a company has a well-defined cybersecurity strategy. Most of the time, cyber threats have no obvious tells on a surface level. that is why using log files to identify threats is more effective. SIEMs have become a central hub of network transparency due to their superior log management capabilities.

According to Gartner, the security and information event management (SIEM) market is defined by customers’ need to monitor event data in real-time for early detection of targeted threats and data breaches, as well as capture, archive, investigate, and report on log data for incident response, forensics, and regulatory compliance. The Gartner Magic Quadrant depicts the strategic positions of four types of technology providers (Leaders, Visionaries, Niche Players, and Challengers) in markets with strong growth and distinct provider differentiation.

The LogRhythm SIEM security product aims to bring together log management, security analytics, and endpoint monitoring and forensics into one package. Security professionals can get a variety of different items combined into one package with LogRhythm SIEM. Threat lifecycle management, security automation and orchestration, targeted searches, and compliance reporting are only a few of the features available.

The following are the key characteristics of LogRhythm SIEM:

Monitoring in Real-Time: To analyze all security events and the forensic data available, this platform employs Automated Machine Analytics. As a result, real-time intelligence alerts on emerging threats are given to all security teams. Not just that, but the threats are ranked according to their risk severity, helping you to focus on the most serious threats first.

Automated Responses: When LogRhythm SIEM detects a threat, the Smart Response Automation Framework can be used to perform various tasks. These can be set up before any incidents happen, so the system simply boots into gear and investigates or responds to threats as soon as they’re detected.

Log Management: Data logging and storage are key elements of any SIEM. You’ve got one of the most powerful and reliable log management systems on the market with this SIEM tool. Every single day, you can store terabytes of data and have instant access to it.

Monitoring of the network and endpoints: LogRhythm SIEM includes forensic sensors that are comprehensive and integrated into the platform. As a result, you’ll be able to see any abnormalities in behavior to react to incidents more efficiently.

Management of the Threat Lifecycle: It is the only tool that offers end-to-end threat monitoring. This means you can handle risks from the beginning to the end, all in one position. It keeps the process under control and making it easy to handle, all while lowering the cost of the cybersecurity tools.

Data analysis to identify threats: It uses data analytics to detect threats well before they develop into major issues. The concept is straightforward: LogRhythm’s data collection helps you to see the footprints of any system in your network, allowing you to identify advanced threats. It’s almost as if you’re predicting something based on past behavior.

Simple to Setup: When used by an experienced and trustworthy security team, LogRhythm SIEM can be set up in a fraction of the time it takes to set up any of its competitors. As a result, the security partner can get things up and running quickly.

Hansight Enterprise SIEM

HanSight mainly sells to channel partners in China, as well as other parts of the Asia/Pacific (APAC) region (e.g., Japan and Singapore) and Latin America. HanSight Enterprise SIEM is the main offering. It is part of a solution ecosystem that includes UEBA, network traffic analytics (NTA) with IDS capabilities, risk management, asset analysis, data loss prevention (DLP), and threat intelligence management. Partnerships with several Chinese security technology vendors allow EDR and cloud workload protection platform (CWPP) capabilities. The platform is available in three forms: software, hardware appliance (for smaller deployments), and hosted platform. On-premises HanSight systems are licensed on a perpetual plus annual maintenance plan. The cost of enterprise SIEM is determined by data velocity (EPS), with a tiered discount. The cost of such modules is determined by the number of users (UEBA), the number of sensors installed and bandwidth (NTA), and the properties (VM and Assets). Hosted Enterprise SIEM is licensed on a subscription basis and is based on regular pricing with an uplift for hosting the application. HanSight enhanced its search capability with the HanSight Query Language (HQL), launched the DLP add-on, and added event aggregation and incident timeline visualizations.

HanSight has a strong ecosystem of technologies that support its core SIEM solution, making it appealing to companies looking to equip a modern security operation center (SOC) with a single vendor. The platform makes use of cutting-edge big data technology and techniques, and it even comes in a cloud-based version. HQL and the search function provide features including an integrated development environment (IDE)-style analysts’ notebook and the ability to share saved searches via QR code. Users offer above-average ratings for service and support as compared to the competition, according to Gartner Peer Insights and vendor customer references.





Log360 is ManageEngine’s core SIEM product, but it also includes many other modules that can integrate with Log360 and address security and IT operations use cases for an extra cost. There are a few of them:

  • With ManageEngine ADAudit Plus you can adjust auditing and reporting for Active Directory (AD).
  • EventLog Analyzer by ManageEngine is used for central log management
  • ManageEngine Cloud Security Plus is a central log management (CLM) and security information and event management (SIEM) solution for AWS and Azure.
  • ManageEngine Log360 UEBA provides user activity anomaly detection capabilities, storage optimization, and the indexing of performance improvements.
  • Data discovery and file server auditing with ManageEngine DataSecurity Plus.
  • Office 365 security and enforcement with ManageEngine O365 Manager Plus.
  • Exchange Server change audits and reporting with ManageEngine Exchange Reporter Plus

ManageEngine Log360 is a software SIEM that can be installed on physical or virtual systems on-premises. Pricing is dependent on the number of event sources or assets in scope and is available as a permanent or term license. The number of assets determines how many components are licensed (which varies depending on the specific component). ManageEngine Log360 Cloud is a web-based, cloud-hosted log storage platform. It saves the information gathered by the EventLog Analyzer log management module. It is not, however, a SaaS-based SIEM tool. Log360 Cloud is a subscription-based service with pricing based on the amount of storage space required. The cost of Cloud Security Plus is determined by the number of cloud accounts managed, with upsell pricing available for additional AWS S3 buckets. Customers of ManageEngine, according to Gartner Peer Insights data and vendor-supplied reference data, are generally pleased with ManageEngine and Log360’s capabilities. Integrations with other products, as well as user, data, and application monitoring, are all areas where there is room for improvement.
