The Best SIEM tools for you will depend on your specific requirements, budget, and organizational needs. There are several popular and highly regarded SIEM (Security Information and Event Management) tools available in the market

What is SIEM?

A security information and event management (SIEM) system is the foundation of security processes in the modern security operations center (SOC).

A SIEM saves security analysts the effort of monitoring many different systems. 

SIEM systems integrate with security tools, network monitoring tools, performance monitoring tools, critical servers and endpoints, and other IT systems.

It aggregates the data, correlates it, analyzes it to discover anomalous or suspicious activity, and generates alerts when it identifies an activity that might be a security incident.

Every cybersecurity workflow starts from log data collection and management, that’s why we curated the Best SIEM Tools list that is highly demanded among enterprises that strive to maintain a stable security posture and comply with necessary regulations.

This overview briefly looks at the top 5 SIEM vendors for the beginning of 2023, both on-premises and cloud-native depending on the infrastructure.

Find out about their distinctive features to choose the best security solution perfectly tailored to your organization-specific needs.

SIEM Capabilities and Applications

SIEM solutions offer various capabilities that provide visibility into a corporate network of devices and apps.

SIEM provides a centralized location for data collection and aggregation, including dashboards that offer insights into overall security and specific threats.

Threat intelligence

SIEM solutions offer insight into known indicators of compromise (IoC) and attacker tactics, techniques, and procedures (TTP).

The tool uses several threat intelligence feeds, organizing and analyzing information on current and potential threats.

Threat detection

SIEM tools can detect threats in various locations, including emails, applications, cloud resources, endpoints, and external threat intelligence sources.

Most SIEM solutions achieve threat detection by employing user and entity behavior analytics (UEBA).

It helps monitor and detect abnormal behaviors indicating a threat, such as compromised accounts and lateral movement.

Alerting and investigation

After detecting a vulnerability, threat, suspicious behavior, or attack, SIEM tools create and send alerts to the relevant personnel for response and mitigation, supporting incident response operations.

You can customize SIEM alerts to suit user needs and use managed rules to react almost in real-time to critical threats.

Some solutions also offer workflow and case management with automatically created investigation instructions. 

Compliance and reporting

SIEM solutions support compliance and alert reporting to help organizations simplify compliance reporting.

This functionality includes data dashboards that help monitor privileged user access and retain and organize event information.

Deployment model: on-premise

Suricata is an open-source engine for high-performance network IDS, IPS, and network security monitoring.

The Open Information Security Foundation (OISF), a non-profit organization, owns it. Suricata can store TLS certificates, log HTTP request logs, and extract files from flows and store them on disks.

Suricata uses automatic protocol detection for protocols like HTTP on all ports to apply the proper detection.

It maintains integrations in JSON and YAML to support databases like Splunk and Elasticsearch and supports multithreading natively.

Features

  1. Multi-threaded Packet Processing: Suricata is designed to be highly performant, with multi-threaded packet processing capabilities that can process high volumes of network traffic in real time.
  2. Protocol Parsing: Suricata can parse and analyze a wide range of network protocols, including HTTP, SMTP, DNS, SSH, and SSL/TLS.
  3. Signature-Based Detection: Suricata uses signature-based detection to identify known threats and vulnerabilities based on patterns and signatures.
  4. Anomaly-Based Detection: Suricata can also use anomaly-based detection to identify potential threats based on deviations from expected network behavior.
  5. Flow Analysis: Suricata can analyze network flows to identify and alert suspicious network activity, including network scans and port scans.
  6. File Extraction and Analysis: Suricata can extract and analyze files in real time, including malware and other malicious files.
  7. TLS/SSL Decryption: Suricata can decrypt SSL/TLS traffic to analyze and detect threats that may be hidden in encrypted traffic.
  8. Open Source: Suricata is an open-source tool that provides organizations with the ability to customize and extend the tool to meet their specific security needs.
  9. Community Support: Suricata has a large and active community of users and developers who contribute to its development and provide support to other users.
