Best Security Information and Event Management (SIEM) Solutions

What is a SIEM Tool?

SIEM, pronounced “sim,” stands for Security Information and Event Management. These types of tools are responsible for discovering and collecting data across network components, primarily in log and event data formats, and storing them in a central place on the platform. This singular source of data and network knowledge is intended to simplify the search and decision-making phases for network experts who look at systems vulnerabilities.

SIEM tools do not only collect and store data for security professionals to interpret, they also use threat intelligence, analytics, and alerting to automate network knowledge and fixes.

Features of SIEM Tools

SIEM tools offer a variety of features to help network security professionals manage threat detection, monitoring, compliance, and data visualization, among other core needs for diagnosing network security threats. Look for some of the following features in your search for the right SIEM tool for your business:

  • EDR and/or XDR: Endpoint detection and response (EDR) and extended detection and response (XDR) are threat detection methods that simplify threat viewing.
  • Intrusion Detection and Prevention System (IDPS): This type of software automates intrusion detection for networks.
  • Automation: Many SIEM solutions automate threat detection and communication about security threats; specific examples include correlation, risk prioritization, Indicators of Compromise, and response.
  • Analytics: Top SIEM tools typically offer a variety of templated or customizable analytics sets, often with workflow management features.
  • System monitoring: Most SIEMs take a holistic approach to system monitoring, providing system metrics from network, database, application, email, IoT, vulnerability file integrity, data residency, cloud suites, virtualization sources.
  • Dashboards and administrative tools: One of the core value-adds of SIEM tools is their consolidation of security information on dashboards; reporting and data visualization also make it possible to clearly share and review network security performance.
  • Compliance features: Some SIEM tools emphasize regional and industrial regulatory compliance with specialized compliance packages and reports.

Why is SIEM Important?

SIEM tools and best practices offer enterprises a variety of security and administrative benefits. Whether it decreases the chance of a breach, improves the daily work of network and security professionals, or increases data visibility for key stakeholders, consider investing in SIEM for some of the following benefits: 

Simplified data logging

Collecting data logs can be tedious. But combing through logs later to find the exact historical data you need can be even more challenging. With flexibility for a variety of data types and a focus on constantly collecting data over time, network security logs will be stored in an up-to-date, easy-to-access fashion whenever your team needs to review them. SIEMs can log thousands of data bytes at a speed and accuracy that makes this tool a game-changer for efficiency.

Breach prevention

Security breaches are not only damaging to the data that has been compromised. They harm the users to whom the data belongs and the company’s reputation as well. There’s even the potential for legal and financial consequences from regulatory bodies. SIEM is one of the most important cybersecurity tools in preventing breaches because it organizes incoming data across all connected network components and makes it legible in a single pane of glass. With an easier visualization of network activity and potential problems, network security professionals can proactively monitor for and address security incidents before they turn into major breaches.

Data and threat sorting

For organizations that collect thousands of data points that need to be monitored and reviewed for security issues, it can often be difficult to pinpoint those problems within the large data set. Even if you’ve found issues that need to be addressed, the vastness of a dataset can make it overwhelming to prioritize which threats need to be addressed first. With features like threat scoring and data filtering, SIEM tools automate the process of scoring threats and ranking their priorities for your team.

Staff and administrative efficiencies

Many of the manual sorting and analysis tasks that network and security staff used to do for security logs can now be handled by SIEM tools. Staff no longer have to spend valuable time on manual sorting work, and they also no longer need to rely on siloed tools for data knowledge.
