Security Information and Event Management (SIEM)
Microsoft Sentinel
Microsoft Sentinel is a Security Information and Event Management (SIEM) solution provided by Microsoft, a major player in the information security space. This solution is designed to collect, correlate, and analyze events from both on-premises resources and cloud-based resources. Microsoft Sentinel integrates tightly with Microsoft’s suite of tools but also supports workloads hosted in other cloud or on-premises environments. Recently, Microsoft has made Microsoft Security Copilot available, allowing users to perform analysis and incident investigation using natural language-based queries.
OpenText ArcSight Enterprise Security Manager
OpenText’s ArcSight Enterprise Security Manager (ESM) is a comprehensive SIEM solution that checks all the boxes for an enterprise-level SIEM. It supports a range of integrations and customization options, allowing security analysts to perform incident response from a single pane of glass. The ArcSight Marketplace enables users to leverage new dashboards, reports, or correlation rules with minimal effort. ArcSight ESM also supports workflow-based automation, allowing analysts to quickly correlate events, reference them in a case, and respond or escalate as necessary. Each action taken can be audited and reported on to maintain service-level agreement (SLA) compliance and track response time. Integrations with third-party systems allow users to begin remediation, such as disabling ports or accounts, or rule sets can be created to automate these steps.
RSA NetWitness
RSA NetWitness SIEM has many of the features necessary for an enterprise-level SIEM, including User and Entity Behavior Analytics (UEBA), automation tools, and architecture flexibility (support for hardware and virtual appliances, software-based options, or cloud deployments). Additionally, RSA NetWitness includes the ability to add context from both business and threat intelligence to incidents based on the asset or user being impacted through integrations with RSA Archer and SecurID. The solution also includes various cryptography tools, such as decryption, decompression, and entropy measurements, to surface encrypted event data or web traffic, providing visibility into this information and bringing it into the SIEM workflow.
SentinelOne Singularity AI SIEM
SentinelOne has built itself as a major player in the information security space through innovation and feature delivery, and its Singularity AI SIEM is a prime example of this success. With Singularity AI SIEM, SentinelOne is modernizing SIEM by an order of magnitude, using modern techniques to scale security operations through efficient ingestion and filtering, robust analytics, and intuitive, resilient automation. The solution integrates tightly with other SentinelOne solutions, including the SentinelOne Singularity Data Lake and endpoint and XDR platforms.
SolarWinds Security Event Manager
SolarWinds is a well-known name in the IT industry, having used a set of free tools and aggressive marketing to earn a place in many small to medium-sized IT shops. SolarWinds Security Event Manager, its SIEM solution, offers tools to detect and investigate threats, analyze and audit events, and even automate remediation steps. Although it may not offer machine-learning-based analytics or the same level of integration with third-party systems as the enterprise-grade tools in this list, SolarWinds Security Event Manager does offer USB device monitoring to mitigate the risks posed by USB flash drives to the network, and it provides an impressive array of compliance reporting to meet applicable government or industry standards.
Splunk
Splunk is perhaps the most well-known entry in this list and is often used as the standard against which SIEM platforms are judged. Splunk offers two versions of its platform: Splunk Enterprise, which can be installed on-premises as a server application on various Unix or Windows operating systems or as a Docker container application, and Splunk Cloud, which allows users to realize the benefits of Splunk in a Software as a Service (SaaS) environment, minimizing infrastructure and maintenance requirements. Both platform versions support customizable dashboards and reporting, anomaly detection, and a high degree of access control. Perhaps Splunk’s biggest selling point is Splunkbase, its app store for the Splunk platform, which includes third-party integrations, analytics, or automation capabilities.
Trellix Enterprise Security Manager
Trellix Enterprise Security Manager (ESM) is designed to provide analysts with critical information necessary for beginning the triage and incident response process. Events are evaluated in the context of related log entries, and ESM guides users through the process of preliminary investigative steps using actionable alerts. The solution offers flexibility in terms of architecture and integration, being available in both physical and virtual appliances in a range of sizes, with virtual appliances supporting a wide array of hypervisors and cloud platforms. Trellix offers content packs that enable monitoring and alerts for specific use cases or partner platforms, and it has integration partnerships with more than a dozen third-party vendors, making ESM incredibly extensible.
