Before we dive into each of the tools, let’s take a moment to review exactly what a SIEM tool is, what it does, and why it’s so important for businesses that are poised for growth.
What is a SIEM?
A SIEM is a Security Information and Event Management tool that provides a real-time live view into the security posture of your organization across all applications and networks. It works by using agents to aggregate data from workstations and log files, and then pulls that information into a single system – the SIEM.
With this data security professionals comb through live events, stop attack attempts, and crush any infection that is attempting to spread through the network. Without a SIEM, admins would need dozens of different logins and dashboards to see the logs and events from servers and applications all across the network.
Centralization also allows administrators to keep an audit of these security events. If a breach does occur, security professionals will be able to use the historic log data collected to aid in a forensic investigation that can not only help find the source of the breach but be used in a court of law as evidence.
SIEM systems go beyond simple antivirus software by providing blanket coverage across an entire organization. With that said, SIEM tools aren’t foolproof. Threats aren’t simply blocked automatically like on a consumer PC. SIEM reports and logs need to be analyzed by both automated systems as well as trained technicians in order to get the most amount of value out of a SIEM deployment.
What does a SIEM do?
SIEM’s have a wide range of capabilities that are often made available as out-of-the-box templates, but in reality, take time to refine and customize. Since every network is different a SIEM can be configured to learn over time what threats look like, versus real user behavior.
Some common SIEM capabilities are:
- Log collection
- Log normalization/filtering
- Alerts & notifications
- Threat response workflow
- Log graphing
- Incident detection
- Automated remediation
Not all SIEMs are created equal, but many will have the capabilities mentioned above in some capacity. You’ll find that some SIEMs leverage artificial intelligence more heavily than others. This can be a huge benefit if you’re dealing with hundreds of gigabytes of log files and supporting a network of many users.
SIEMs are powerful tools that can also automate threat response. If a particular action or series of actions is detected you can configure the SIEM to take a specific action. This could be as simple as locking a user account and creating a helpdesk ticket, or as complex as changing network settings to isolate a ransomware infection.
Since there are so many different variables at play. SIEMs still need to be operated by a professional. While it’s true there are many automated and machine learning features that SIEMs can use, it will only be as effective as the operator configuring it.
Should I use a SIEM?
Building a SIEM system is in fact an investment that requires time and money. As cyberattacks such as ransomware and data theft rise sharply, so does the need for organizations to protect themselves and their customers. In the past, companies wanting to implement a SIEM needed to invest thousands of dollars in hardware, and even more into staff. Today there are SIEM tools that are built in the cloud, making the implementation of a SIEM system more affordable than ever before. Even with this change in expense, smaller companies may struggle to justify allocating the funds to set up a SIEM for their organization.
In many cases, small businesses will need threat protection, but not at the level that a SIEM provides. Generally, the larger you are as an organization, the more of a target you are for an attack. Even medium-sized businesses that are expecting to grow over the next few years should seriously consider a SIEM.
It’s often during these periods of growth where lax security policies and disorganization come to haunt companies who don’t take security seriously. SIEMs are an investment in your company, your uptime, your data, and ultimately your ability to serve your customers.
Core SIEM Components
There are some core components of a SIEM that allow it to function in a way that provides blanket security coverage. We’ll touch on each of the core components that make SIEMs as powerful as they are.
Log Management
At the center of any SIEM product, you’ll have a log management core. This system will be able to intake log data from dozens of different sources, automatically scan it for security events, and then make those insights available to administrators for further action. Without log analysis, SIEMs would have vastly limited capabilities and visibility into what is happening across different servers and applications.
As you can imagine processing log data across multiple servers, vendors, and environments can be chaotic. SIEM tools have built-in filters and other features that consolidate and normalize log data so that it can be more efficiently interpreted by both artificial intelligence and human investigators.
When the data is normalized, it is often compared to events from previously recorded data. This helps the system create a baseline that is customized around how your organization operates. For instance, if Sue suddenly logs into her PC remotely at 3 am from a different country, a quick check of recent records would show this behavior as anomalous. This could fire off an alert to an administrator, or execute automation to disable her account.
Lastly, this log data can be used to help assist in audits to demonstrate compliance, or assist a cybersecurity investigation after a security incident has occurred. Many SIEM tools feature compliance reporting tools that allow admin to run a scan and report together to demonstrate compliance across an entire organization relatively easily.
For cybercrime investigations, logs often need to be parsed manually. A good SIEM tool will have features that assist in the manual investigation and make the manual review process simpler through advanced search features, log comparison, and backend scripting options.
Alerts & Notifications
A SIEM is essentially useless if it cannot communicate with staff that something is wrong. In all SIEM tools, there is some form of alert configuration and option for notifications. More advanced SIEM tools will allow for custom alerts, multiple combinations of conditions, thresholds, and variables to be set.
This is important because it can be very easy to generate false positives if alerts are misconfigured. More common than false alarms is alert fatigue. Misconfigured alerts can bombard network operation teams and help desks with insistent alerts that may get ignored over time. Many SIEM platforms have built-in intelligent alerting which works to automatically prevent this from happening.
Threat Response
Once an event has been identified it’s up to the admin to respond. Blatantly malicious actions can be resolved with automated remediation that stops it in its tracks. Manually reacting to all threats becomes unfeasible, especially at an enterprise level. SIEM tools include a combination of features that help admins automate specific responses based on severity, context, and how frequently the action happened.
For example, if a staff member just tried to send PHI in an email an action could be taken to automatically stop that from happening, alert the user, and send an email to the supervisor. If that same user were trying to move 100GB of PHI to their flash drive, the response would be much different.
Ultimately it’s up to the security team to fine-tune these rules over time. With the right SIEM tool, a proper balance can be achieved.
Dashboards
Visualization is key when it comes to keeping NOC teams, admins, and executives informed on the security of the organization. Good dashboards help give teams a general idea of what is happening, where to dive deeper, and what to prioritize next.
Different views can be created to help teams get a live look at what is happening, and compare metrics.
Dashboards can often be configured based on personal preferences but also made into a template so that teams can view insights and statistics that are relevant to their duties.
The Best SIEM Tools
There are a large number of SIEM tools and platforms to choose from, and not all are created equal. Some platforms are solely cloud-based, while others offer on-premises solutions as well. There are open-source SIEM tools that might appear budget-friendly on the surface, but end up burning tons of time learning the tool and trying to get it to work how you want.
Oftentimes the best SIEM tools combine a mix of templated features that allow for customization and don’t box you into any particular vendor or solution. Having a wide variety of integrations available, as well as flexing monitoring options ensures that SIEM will be able to grow and scale with your organization over time. Below we’ll take a look at some of the best SIEM tools available today.

7. Heimdal Threat Hunting and Action Center
Heimdal Threat Hunting and Action Center is a cloud platform that includes a SIEM system. It works with on-premises Heimdal cybersecurity tools to get activity reports from all around a protected system’s network. The service requires at least three different Heimdal tools to be operating on the site. The main tool that this SIEM works with is the Heimdal Next-Generation Anti-Virus, which runs on Windows, macOS, and Linux. That package also provides a mobile device management (MDM) tool to watch over devices running Android and iOS.
Key Features:
- Unified Cyber Security System: Integrates on-premises Heimdal tools for cohesive protection.
- Vulnerability Scanning: Identifies and assesses system vulnerabilities.
- Threat Analysis: Scans uploaded reports to detect threats.
Why do we recommend it?
Heimdal Threat Hunting and Action Center is an XDR that pulls together the activity reports of on-premises Heimdal tools and performs threat hunting to spot intrusion and advanced persistent threats. The tool can send back instructions to shut down discovered threats automatically. This is a cloud-based system.
The Threat Hunting and Action Center system relies heavily on the NGAV package for source data. The cloud system will not activate unless two other tools are also present on a site. These can be Network Security, Email Security, Patching & Asset Management, or Endpoint Security.
The cloud platform of Heimdal forms a threat intelligence system within an organization. The Action Center spreads information about activities on one device to other devices on the network. This enables local protection systems to pay extra attention to traffic from a specific source or even block it.
The SIEM unit on the Heimdal platform is called the XTP Engine – XTP stands for Extended Threat Protection. If a threat is identified, the Action Center kicks in. This module contains playbooks that are activated by particular types of threats. That is, there isn’t one set of rules, but a list of alternatives, each of which will be triggered by a different type of threat.
The Action Center’s playbooks involve sending response instructions to the device that is under attack. The system might also need to trigger actions in other devices in defense of that vulnerable device.
The Heimdal system particularly looks for anomalous user account activity, lateral movements, signs of detection evasion, data movements, and unusual file changes. This means that it will detect insider threats, intrusion, malware activity, such as ransomware, and data theft.
Who is it recommended for?
You have to already have two Heimdal products operating on your site before you can use the Threat Hunting and Action Center system. One of those two tools needs to be the Heimdal Next-Generation Antivirus, which is available for Windows, macOS, and Linux.
