A company had already invested millions of dollars into cybersecurity tools, but was unable to provide an explanation as to why ransomware alerts were taking hours to investigate.
They had dashboards all around their SOC team! Alerts kept firing. No one believed the noise was any longer.
One of the reviews that I remember said,
We see what’s going on but we don’t have clarity.”
This is what leads many businesses to be misled by the difference between SIEM, SOAR and XDR. They’re sold as replacement products by the vendors. They are not.
I’ve seen cases where companies spend too much money on the wrong platform because they purchased a more complicated platform rather than a one that was a solution.
There are times when a business requires the visibility to be improved. In some instances it has to be automated. Faster detection and response sometimes is required.
There are a lot of different issues there.
If you’re looking to determine what exactly your business needs, this guide will help you to not end up with an expensive mistake.
Here is the uncomfortable truth most vendors avoid
Some companies don’t require all three.
It’s a curious thing to hear that as cybersecurity marketing continues to advocate for platform consolidation, it’s now encouraging users to keep their data off such platforms.
It’s often more harmful than helpful to purchase several tools before realizing your operational level of maturity.
I have seen a mid sized SaaS company spend the whole budget on a top of the line SIEM deployment and, 6 months later, realize that they didn’t have the personnel to properly tune the alerts to get the most out of the SIEM.
The result?
Thousands of bogus alerts.Thousands of false alarm. Security fatigue. Then ultimately, unheard alarms. It’s a hazardous game to play.
With increasingly complex detection problems and the rapid volume of alerts, organizations continue to suffer significant detection challenges and from alert overload, particularly if they have limited staffing in their internal security operations team, the 2025 edition of the Verizon Data Breach Investigations Report reveals. The failure of security tooling is in many cases due to the lack of ability to effectively get the tools up and running.
Technology matters. But there is a more important aspect to operational fit operational fitness. To determine which of the three (SIEM, SOAR, or XDR) you should select, it is important to know what they solve.
Let’s stop treating them like the same thing
Practically speaking, I describe them to the students as:
SIEM helps you see. You can make quicker decisions with SOAR. By identifying and responding to threats smarter, XDR enables you to detect and respond to threats. Simple explanation, yes.
Oversimplified?
Also yes. However, it does help those at high levels to avoid getting them mixed up.
SIEM: Centralized visibility first
Log data is gathered from all your environment via a Security Information and Event Management (SIEM) platform.
- Servers.
- Applications.
- Firewalls.
- Identity systems.
- Endpoints.
- Cloud infrastructure.
It is designed to do aggregation, monitoring and correlation. You can consider it your organisation’s security recollection. With no SIEM, many companies run blind as their logs reside in separate systems.
For instance, let’s take Microsoft’s. Microsoft Sentinel which is priced on the basis of data ingestion and is cloud-native for SIEM. It’s commonly used to collect logs from a hybrid infrastructure environment for enterprises.
However, these are some things that vendors tend to gloss over. It is difficult to implement SIEM.
Really messy.
You don’t have good alert tuning, you get lost in alerts. A lack of strong policies decreases the quality of detection. When your analysts are not experienced, the investigation time goes out of hand.
I have personally witnessed teams spending months to set up dashboards and find that they still don’t have any useful threat context. Simply being visible is not enough to make you secure!
Why are companies suddenly obsessed with SOAR?
As humans are costly. Well, it may be harsh to say, but it’s true. The real problem with cybersecurity hiring is there’s a talent shortage.
As analysts spend hours working on repetitive investigations, executives ask themselves if there is better ways to do that with automation.
Which is where Security Orchestration, Automation, and Response (SOAR) comes into play. Workflow automation is the key aspect of SOAR platforms. Suppose that is a phishing e-mail notification that arrives.

By automating portions of this process, SOAR can alleviate the burden of having to manually check indicators, isolate systems and make tickets.
- Ticket creation
- Threat enrichment
- Indicator lookups
- Containment workflows
- Response playbooks
I can still recall a financial services team which took nearly an hour and a half to investigate repetitive credential phishing attacks.
Once the automation playbooks were put in place, investigation time has dramatically reduced. However, that’s the error that businesses make. They believe that, in their opinion, SOAR takes the place of an analyst.
It does not.
Bad workflows that are automated at scale, result in bad outcomes at a faster rate. There’s still need for people with some experience to determine logic. There’s still governance that needs to be had. And, frankly, an unruly automation system is not a system at all it becomes chaos, rather pretty quickly.
A quick reality check on SOAR costs
Operational complexity is another drawback of SOAR. The charge for licenses can quickly add up. There’s much more to integration than meets the eye. It will take some time to create a custom playbook.
It’s often this reason that adoption is tough for smaller businesses. An enterprise-level orchestration isn’t necessary for a business that has only 5 persons in its IT team. This could provide a more significant return on investment in other investments.
XDR arrived because security teams were drowning
The paradoxical thing is a lot of companies purchase SIEM initially for the fact that they believe they are more enterprise ready. However, in certain environments, using XDR could be the better choice of a starting point.
That surprises people.
Extended Detection and Response (XDR) is all about connected detection on endpoints, identity, cloud workloads, email and networks.
XDR focuses on correlated threat detection, rather than gathering all the data that SIEM does. Does its best to minimize alert fatigue. That matters.
A lot.
I have had situations where I would find that all the computers in the team were turning off the alerts completely so that every morning would appear to be a thousand blinking alerts! It’s a way of working no one can do it like that.
Aimed at cutting down the noise and speeding up investigations, platforms such as CrowdStrike Falcon, Microsoft Defender XDR and Palo Alto Cortex XDR hope to do just that.
For instance, Palo Alto Networks has openly talked about the use of behavioural analytics in Cortex XDR to link up with the “scattered” attack signals that are generally not seen by traditional monitoring in siloes.
That sounds like some technical jargon, but it’s very simple what the business implication is. Less wasted Analyst Time. Faster containment. Lower breach impact.
Organizations that have a mature security automation and AI-assisted response process tend to lower the cost of a breach, and speed up the time to contain and stop the attack, according to Cost of a Data Breach research by IBM.
It’s a concern of CFOs that it’s a concern of CISOs. Because responses that are late will cost lots of money rather rapidly.
When the wrong tool created bigger problems (Case Study)
There was one healthcare technology firm that I advised with about 700 workers. First they purchased a top of the line SIEM. But on paper, it all seemed to make sense. Regulatory pressure. Audit requirements. Compliance reporting.
They didn’t account for the expenses of running the business, though. Log volume exploded. Alert fatigue was an issue. Medium priority alerts became unimportant to analysts as they could no longer keep up with them.
Eventually, the expansion was halted and XDR was introduced to help do a better job of improving the signal. It was quite apparent the difference. Analysts were able to spend less time on the “irrelevant” activity.
The time required to conduct a safeboxbd incident investigation decreased. Security confidence improved. What is interesting, is that they retained the SIEM.
However, its functions were altered. Compliance reporting remained as is. There was a gradual move towards XDR threat detection. The mixed strategy of using one system to solve some problems, and another to solve others was much more effective than attempting to use one system to solve all the problems.
Expert Insight
As Frank Dickson from IDC has repeatedly emphasized in cybersecurity research, organizations should align security tooling with operational maturity rather than chasing feature lists. Mature security outcomes usually depend less on buying more tools and more on reducing investigation friction.
That advice sounds simple. But companies ignore it all the time.
“The biggest cybersecurity mistake I keep seeing is buying enterprise-grade tooling before building the operational maturity to use it well.”
I stand by that. Because I have seen it happen repeatedly.
So which business actually needs what?
Here is where things become practical.
Small businesses or lean IT teams
When there are limited staff members in your organization, XDR is a more likely place to begin. The need for quicker visibility without being overwhelmed with engineering work.
Large volumes of data can bog down smaller teams with a heavy SIEM deployment. It may be too early for SOAR. Prioritize simplicity.
Mid sized businesses with compliance pressure
The difficulties lie here. For finance, healthcare and regulated SaaS, SIEM typically is required for log retention and auditing.
However, when used in combination with XDR, SIEM can provide a higher level of detection quality. Seeing is believing, but seeing and acting is better. This is a typical formula that is effective.
Large enterprises with mature SOC operations
Scale is when SOAR is useful. When the investigators follow the same sequence of questioning the same investigations, automation can provide operational savings.
This is particularly the case in large enterprises with thousands of alerts every day. Still, maturity matters. Reliable detection logic is required to work with automation.
What should your team do this week?
Run a brutally honest maturity assessment. Not a marketing exercise. An honest one.
Ask three questions:
- Are analysts overwhelmed by alerts?
- Do we lack centralized visibility?
- Are repetitive investigations consuming time?
The answers you come up with head in the right direction to the solution. Many times, alert fatigue is an indicator of XDR. There are gaps in visibility, this points towards SIEM. Looks like so many practices that repeat themselves towards SOAR. It is not necessary to have a consultant to answer those questions. Intake this week is open if you are interested.
Also, in case your cybersecurity plan involves identity protection, you might wish to tie this into your next article about implementing zero trust. It obviously follows on from the conversation on detection & response maturity. Similarly, a guide to maintaining the security posture of a cloud environment would be a good addition to help organizations assess their hybrid monitoring requirements.
What businesses usually get wrong about SIEM vs SOAR vs XDR
These take the stance that the more they purchase in security, the more secure they will be. At times it’s additional dashboards. More licensing costs. More confusion.
And, more tellingly, less speedy response to incidents.
The best security teams I’ve been at, usually didn’t have the most tools. They had the most straightforward processes. Most executives don’t realize that difference is important. So, if you’re considering SIEM vs SOAR vs XDR, you should stop asking yourself which of these platforms is the most advanced.
Which problem are you facing most pain in operation? This answer is typically the beginning to where you are going. And, for the most part, it’s going to be more expensive to get on the wrong platform than to wait a quarter, and then get onto the right platform.
FAQs
What is the difference between SIEM, SOAR, and XDR?
SIEM focuses on collecting and analyzing logs from multiple systems for visibility and compliance. SOAR automates security workflows and incident response tasks. XDR improves threat detection by correlating signals across endpoints, cloud, email, and identity systems. In simple terms, SIEM helps you see, SOAR helps you automate, and XDR helps you respond faster.
Should I choose SIEM or XDR for my business?
The answer depends on your biggest security problem. If your business struggles with compliance, audit requirements, or centralized logging, SIEM is often the better fit. If your team faces alert fatigue and needs faster threat detection, XDR may deliver quicker operational value.
Do businesses need both SIEM and XDR?
Many mid-sized and enterprise organizations eventually use both technologies together. SIEM helps with compliance reporting and long-term log storage, while XDR strengthens threat detection and investigation speed. Combined, they often create a more effective cybersecurity strategy.
Can XDR replace SIEM?
Not completely. XDR improves threat detection and response but usually does not replace SIEM for compliance logging, forensic analysis, or long-term data retention. Most mature organizations use XDR alongside SIEM rather than replacing it.
How do I know whether my company needs SIEM, SOAR, or XDR?
Start by identifying your biggest operational challenge. If you lack visibility into security events, SIEM may help. Analysts struggle with too many alerts, XDR often makes more sense. If repetitive investigations consume time, SOAR can automate workflows and improve response efficiency.
