Do you expect the best or is your business protected? Cyber-attacks are not as easy to detect and are faster in 2026. The other problems like ransomware, phishing, can go undetected for weeks.
It used to be that you could keep a close eye on security, but that isn’t possible now. So you’re purchasing a tool, or real protection?
What is MDR, XDR and SIEM?
Security information and event management system (SIEM) gathers logs from all throughout your IT world and then alerts your in-house security team. But it is good for compliance, it is good for visibility and it is not threats. There is someone in your group that needs to take action.
That’s just the beginning of extended detection and response (XDR). Gathers the signals (telemetry) from endpoints, networks, email, cloud and correlates the telemetry across every layer and automatically performs some actions. It’s endpoint detection and response (EDR) elevated, enhanced and expanded.
Managed detection and response (MDR) is unique from that. It is not some tool, it’s a service. Human analysts watch your surroundings 24 hours a day, search out threats and actively respond. This is not the software that you’re purchasing. A completely staffed security operation that you purchase. This is what 24×7 detection, investigation and containment AI4IT offers with its MDR service.
The Comparsion on What Matters
Detection
Only those things that are programmed into SIEM’s rules will be detected. One of the abilities that XDR can use to identify lateral movement and fileless attacks is behavioral analytics. That’s what MDR’s human threat hunters add.
Quick response to alerts and stops
SIEM alerts and stops. Some containment automation is achieved with XDR. MDR providers isolate systems, block IPs and disable accounts all within minutes.
Difficulty
SIEM licensing is approximately $20k – $500k per year, and offers two – three full-time engineers to use. XDR can be less expensive, but needs expertise within the organization. No hiring, no Staffing issues and MDR services will just cost you a few cents, as compared to your SOC.
Compliance
SIEM is the market leader in logging and audit trails. The reports are automatically mapped to MDR as well as HIPAA, SOC 2, ISO 27001 and GDPR. Can be detected via XDR but not as fully as SIEM does for logging.
The Role of EDR and SOC
EDR watches over your endpoints, and records unusual activity on the device. This visibility expands to the whole environment with XDR. MDR’s human analysts coverage, add to this.
Most businesses would find the traditional in-house SOC to be too expensive, averaging at $1.5M – $3M per year. That’s where AI4IT’s cybersecurity services can help.
When SIEM Is the Right Fit and When It Is Not?
If your enterprise has any of these, then the SIEM approach would be a good one.
- A large in-house security team and a team of its own engineers.Their own large security team, along with their own engineers.
- Requirements to store data for extended periods of time, like logs.
- In complex environments with hundreds of data sources, needing one view of all the data.
- A budget for the continuous tuning, management and analyst salaries.
Does not make sense when:
- Do not have specific security personnel to follow up on alerts
- Having sight is not enough – you need to be able to respond swiftly to incidents.
- Your business is adding new and additional data security demands, but that’s not all.
- When used by the right hands, SIEM is a great tool. It doesn’t have hands, it is a cost noise maker.
The AI4IT IT Compliance and Governance services tie governance controls straight to your security operations when evaluating compliance posture along with SIEM.
Which One Fills the Gap between MDR and XDR?
For those with internal analysts that require more sophisticated tools, it’s the ideal choice for XDR. However, on Sat night at 2am no one is there and no threats. Where needs are results, where not tools, MDR as a powerful tool comes into play; never off the hunt, never off the game.
There are many organisations that have both XDR technology layer, and a human layer that is on top of this, called the MDR layer.
A Simple Framework Adapt to select
The decision on which to choose will be based on three criteria: Team size, Budget and Risk tolerance.
- If you have a strong and knowledgeable in-house security team with many compliance reporting requirements, then SIEM may be the ideal solution for you.
- If you have internal analysts who want to have a better tool and visibility into their environment, choose XDR. Identity and Access Management services help you stay secure across all users and systems.
- If you’re not looking to establish a SOC on your own, and just need to have a constant threat detection and response service on your side then you’re looking for MDR. Ideal for small and medium-scale businesses.
