Just like it sounds, any SIEM vendor or SIEM supplier is a company that provides SIEM tools, systems, and solutions. A SIEM is a solution that collects log, event, and other types of data from all across your system, analyzes patterns in that data for potential security weaknesses and threats, and flags those threats for your analysts and cybersecurity people. Note, the best-in-class will also deal with many kinds of threats automatically as well.
Choosing the best SIEM provider will be based on your infrastructure, budget, risk appetite, and internal expertise.
Typically, SIEM technology is licensed to users. Perpetual licensing (CAPEX) was once common, but OPEX (subscription type) licensing models are now more common. Actual costs can be based on events per second, data volume per day, server use, or other factors. Just make sure you choose a pricing model that will be efficient for you and scales economically with your usage.
Does a SIEM need on-premise hardware, dedicated servers, or storage infrastructure, or is it entirely cloud-native? Infrastructure overhead is IT hours and CapEx costs. Are you going to have to provision servers and then maintain them? And what do you do when you have to scale storage or processing? Solutions that are cloud-native and that scale automatically can minimize your up-front costs and your ongoing operational overhead.
Cloud-native SaaS platforms like Huntress remove infrastructure overhead completely, with no servers or storage to maintain, and automatic scaling to your capacity. Our lightweight collectors deploy in minutes and use a fully encrypted, outbound-only connection to keep your operations and data secure.
Some systems log and retain everything, and practically forever. Others are more limited. Make sure the data cap policy fits your forensic and compliance needs. Ask early on: What is the retention period at each pricing tier? How does it work when you hit the cap (is no new data ingested, or are you charged a lot more money to go over)? If you have regulations to follow, such as HIPAA, PCI-DSS, SOC 2, etc., make sure that the retention windows meet your minimum needs without forcing you into a more expensive plan. Be careful of vendors that charge additional fees for archive access or longer retention. "Unlimited" retention offered by some vendors may have limitations in their fine print regarding hot vs. cold storage costs.
Ask vendors if they have out-of-the-box parsers for your current tech stack, like Windows, Cloud (AWS, Azure), M365, and firewalls. If you need to write and maintain your own log parsers, you'll most likely need to write and maintain a regex. The more native integrations a vendor has, the quicker your deployment will be, and the less time your team will need to spend on configuration.
At Huntress, our pre-built parsers have integrations for Windows, Syslog, AWS, Azure AD, M365, firewalls, and more. No custom regex required at all.
Native analytics from these solutions are a sort of "green listing" that can be extremely effective. Pre-configured visibility lessens the need for custom queries and external BI tools, and can get you protection against common threats, like ransomware IOCs, privilege escalation, or lateral movement, for example, and from day one. However, check that you aren't locked into vendor-defined analytics only. Can you still build custom rules and queries specific to your environment, threat landscape, and compliance needs? Can you also be sure that the analytics output from your solution integrates cleanly with existing ticketing, SOAR, or workflow tools? You don't want top-notch detections that can't trigger the right response in your existing stack.
Some SIEMs spew such a high volume of low-value alerts right out of the box that you can't possibly use them without weeks of manual tuning. Find out how vendors address alert fatigue: Do they filter noise at the edge? Do they have smart defaults that minimize false positives from day one? The difference between a SIEM that has painful tuning that must be done up front versus one that's production-ready immediately can translate to weeks of value lost.
The best solutions filter noise at the source. Huntress has smart filtering enabled by default that drops low-value noise at the edge, letting you go live without painful upfront tuning and reducing alert fatigue.
A good SIEM platform can scale up or down, but buying more than you need is rarely a good strategy to save money. Know your current threat profile, event volume, and resourcing levels. Pick a solution that fits today’s needs with the option to grow.
Also, think about your internal security team’s skill set. If you have a robust, mature SOC staff, you may value sophisticated query languages and customization. If you’re a small team with limited resources, functionality around automation and built-in threat intelligence will let you focus on strategic investigation and reduce manual triage time. Your use cases will also depend on your infrastructure complexity. A small company with 50 endpoints and a few common cloud apps will have vastly different requirements than an enterprise managing hybrid infrastructure across numerous regions.
Ask for customer references from companies similar to yours in size and industry from the vendors you’re evaluating. And make sure scaling up in the future (more data sources or users, higher retention, etc.) won’t require a painful data migration or platform switch down the line.
Ask yourself if you need the vendor to provide a SOC in addition to the technology. If you have 24/7 coverage and advanced threat analysis skill gaps in your team, then a SIEM with an embedded MDR capability may be the tipping point for actually responding to threats, as opposed to merely detecting them. If they have people at the wheel, ask about analyst response times and how they fit into your incident response workflows.
Huntress provides a 24/7 AI-assisted human-led SOC. Our analysts begin monitoring and correlating as soon as the data starts flowing.
Time-to-implementation can range from a couple of days to many months. Some vendors simply drop a folder of documentation on your doorstep and say, “Good luck.” Others have subject matter experts available to direct the implementation, configure data sources, and fine-tune retention policies. Ask about average time-to-production: days, weeks, or months. Is the hands-on support included, or professional services that will be billed hourly?
White-glove onboarding slashes time-to-value. With Huntress, a seasoned engineer configures log sources, retention policies, and alert routing. That means you'll be live within hours.
Licensing fees are unavoidable, and staffing and resources nearly so. However, some SIEM vendors have hidden “gotcha” fees that you need to watch out for. Some vendors may place access to high-end functionality or data sources behind additional paywalls. Some may charge substantially more for extra storage or processing. Mainly, make sure that you know what you're getting into by reading that fine print and getting clarity on the full cost of ownership before you commit.
Fluff aside, Huntress competes with the best SIEM vendors worldwide and often provides a higher ROI for many organizations. When it comes to value, simplicity, and support, we check all the boxes. We've built a cloud-native platform of lightweight collectors, smart filtering, deep integrations, and 24/7 SOC coverage—so you can have enterprise-class security without the enterprise complexity.
