The complete guide on what is SIEM and how important for your business. You will also understand deference between SOAR and SIEM.


Security information and event management (SIEM) software is not a new concept for business owners. The software exists for more than a decade,Guest Posting while progress is being made in the development of better versions, providing comprehensive security solutions for companies. Initially evolving from a discipline of records management, SIEM combines Security Event Management (SEM) with Security Information Management (SIM) to adopt the current technological form.

The SEM component of this technology works by examining the event and recording real-time data that is then used for threat monitoring, finding the correlation of events and organizing an incident response. This works in constant correspondence with SIM that assembles, analyzes and reports on the registration data.

How does SIEM work in implementing cybersecurity?

The SIEM tool has become a fundamental approach to guarantee cybersecurity for companies. It is not just an agent but a multitude of diverse tools that monitor and analyze various data sets. SIEM works by collecting data and then converting events and log entries into usable information through statistical correlations. While other security tools present information, SIEM helps extract real value from them by making the data accessible to the incident response team. 

SIEM enables Incident Response Teams with security information through:

  • Data collection from various sources.
  • Consolidation of registry entries and events for the analysis of security anomalies
  • Specifically identifying the real security breach so that the team can investigate the problem and resolve it. 

Is Open Source SIEM worth it?

SIEM has been a standard tool for managing cybersecurity operations for large companies for some time now. But for small businesses, looking for SIEM providers that implement SIEM would mean a great investment. The open source SIEM seems compelling to these companies due to its lower licensing cost and affordable features. 

Comparison Between SIEM Open Source and Enterprise-grade SIEM

The open source SIEM is specifically designed to support small and medium-sized businesses with basic security analysis functions. With the main features of open source SIEM, organizations that have begun recording and monitoring security incidents can benefit significantly. The open source SIEM allows them to reduce the initial costs of security software license and evaluate the security information of their business before they can decide to expand their investments in cybersecurity.     

There are, however, several limitations to employing open source SIEM among businesses: 

  1. Sometimes, even the best open source SIEM technology does not provide essential SIEM features such as reports and remote accessibility and log data management. 
  2. The open source SIEM allows companies to save costs initially, but needs regular maintenance that is expensive and requires a lot of work. 
  3. Maintenance efforts for an open source SIEM continue to increase as the size of the organization grows. 
  4. The implementation of the best open source SIEM requires experienced security professionals and experts who can also devote a significant amount of time to the cause. For smaller organizations, this could be a problem. 
  5. Even if organizations invest in the best open source SIEM, it is not imperative that SIEM open source manage or even provide storage functions. For the large volumes of data that companies handle daily, this is an important concern. 

The enterprise-level SIEM comes with advanced security information management that can handle and monitor large-scale data that can then be centrally configured to solve problems. Only the business grade SIEM provides the characteristics of the next generation SIEM. Therefore, although this may not be as profitable as the open source SIEM, investing in this advanced security technology can be beneficial in the long term. 

The implementation of higher levels of business security is the need for time, considering how the frequency of cyber attacks has increased in this recent era of the Internet. Choosing the right SIEM providers for your business is the first step in ensuring the cyber security of your organization. If you are looking for SIEM providers, Anlyz offers a healthy business security solution with Cyberal, a SIEM cognitive software powered by next-generation technologies for enterprise-level security.

Within the cybersecurity posture of companies, the latest SOAR technology seems to be more functional than the existing SIEM platform. Organizations looking for SOAR vs. SIEM options should understand that, in reality, SOAR complements SIEM, rather than replacing it. 

SIEM looks in the haystack for security information, the exact incident that can lead to a cyber threat. Then alert the security teams about the security incident and trigger an automated response. 

SOAR takes response capabilities to the next level. It raises a fine in the incident tracking system by automatically providing contextual data and information to the security team and arming them with various combat methods to deal with the security incident. SOAR systems promise to identify and initiate a firewall response that provides security analysts with the optimal route needed to identify, detect and analyze threat incidents. 

In conclusion, building a robust corporate security framework is a must for companies that cannot risk exposing their confidential data to cyber attacks. Investing in a reliable business-level SIEM platform significantly improves the business cybersecurity landscape.
