Collect, Correlate, and Act on Security Events Across Your Entire Environment
A Security Information and Event Management (SIEM) platform aggregates log and event data from across your environment — correlating signals from endpoints, network devices, cloud services, and applications to detect threats that no individual tool can see in isolation.
What RLM Delivers on SIEM Platform
SIEM is the detection backbone of most enterprise security programs — but it's also one of the most expensive and operationally demanding security investments. Platform selection, data source tuning, and detection rule quality determine whether your SIEM drives security outcomes or generates alert fatigue.
How We Approach SIEM Platform
We work SIEM Platform the same way each time: establish the baseline, test the market properly, negotiate on evidence, and stay involved through implementation.
Current Logging & Detection State Assessment
We assess your current logging infrastructure — what's being collected, what's being missed, detection rule quality, and the alert-to-incident conversion rate that quantifies detection effectiveness.
SIEM Platform Evaluation
We evaluate SIEM platforms — Microsoft Sentinel, Splunk, IBM QRadar, Elastic SIEM, Exabeam, and MDR-delivered SIEM services — against your data volumes, detection requirements, team expertise, and total cost of ownership.
Detection Engineering Design
We design the detection engineering framework — use case prioritization aligned to MITRE ATT&CK, detection rule development standards, false positive tuning process, and the alert triage workflow.
Data Source Integration Planning
SIEM value is proportional to log coverage. We design the data source integration plan — priority log sources, normalization approach, retention policies, and the cost-optimization strategy for high-volume sources.
SIEM Platform Evaluation Criteria
These are the dimensions we have seen separate a SIEM Platform deployment that works from one that quietly becomes shelfware.
Total Cost of Ownership
SIEM TCO includes ingest pricing, storage, compute, and operational overhead. Evaluate full TCO across your data volumes — cloud SIEM pricing models can be unpredictable at scale; Splunk licensing in particular requires careful modeling.
Detection Quality vs. Coverage
SIEM coverage (more log sources) and detection quality (better rules) are independent dimensions. Evaluate detection rule quality — specifically MITRE ATT&CK coverage and false positive rates — not just data source breadth.
Analyst Workflow Quality
SIEM value is realized through analyst investigation efficiency. Evaluate the investigation workflow — case management, enrichment integrations, timeline views, and the analyst experience that determines how quickly real threats are identified.
Cloud-Native vs. On-Premises
Cloud-native SIEMs (Sentinel, Elastic) offer elastic scaling and cloud service integration; legacy on-premises SIEMs provide data sovereignty. Evaluate the deployment model against your compliance requirements and cloud workload mix.
SOAR Integration
SIEM detection must connect to response. Evaluate the native SOAR integration quality and the orchestration capabilities that automate repetitive analyst tasks without requiring a separate SOAR platform.
MDR as SIEM Alternative
Managed Detection & Response services include SIEM capabilities operated by expert analysts 24/7. Evaluate MDR against building and operating a SIEM internally — for most organizations below 1,000 endpoints, MDR delivers better security outcomes at lower total cost.
"We had three overlapping security tools doing the same job. RLM helped us rationalize the stack, cut spend by 30%, and actually improve our detection coverage in the process."
We are paid by the provider you choose, which means we have no reason to steer you toward any particular one.
Where This Matters Most
Sector-specific considerations we see repeatedly in security engagements.

RLM is vendor neutral. These are among 600+ providers in our evaluation set — inclusion here is not an endorsement, and we are paid by the provider you choose, not by any provider in particular. How that works →
