Data sources and collection
Identify useful records, assess their quality and plan how to connect available sources.
Data
analytics
Operational and security data analysis
Turn operational and security data into information you can act on. We help you identify useful sources, collect and evaluate available records, and interpret findings in the context of your environment.
Start with the question you need to answer
Which events deserve attention? How do records from different systems connect? What causes recurring problems? What evidence do you need for your next decision?
How we can help
Network traffic analysis
Understand communication patterns, load and unusual changes in network traffic.
Security event investigation
Correlate available records to reconstruct events and support further investigation.
Reporting for IT and management
Turn findings into understandable reports that support operational decisions.
Useful results for your team
We agree the question, data sources and expected output first. The result can be an event analysis, an explanation of unusual behaviour, selected indicators or a report for decision-making.
For technical teams
Timelines, traffic patterns and relationships between available records to support investigation and troubleshooting.
For operational decisions
Understandable reports that help set priorities, plan capacity and decide where further investigation is needed.
The goal comes before the tools
Data quality, access and timeliness determine what can be answered reliably.
-
Define the question
Agree the problem and the decision the analysis should support.
-
Identify the data
Review available sources, quality and retention.
-
Evaluate
Compare records and investigate patterns or deviations.
-
Interpret
Explain findings, limitations and practical next steps.
Typical questions we help answer
These examples illustrate possible uses. The scope depends on the records available in your environment.
Is this communication suspicious?
Situation: A device communicates with an unfamiliar destination.
Solution: Build a timeline from available records and, where appropriate, add Group-IB threat intelligence context.
Benefit: Better evidence for deciding what to investigate next.
Why is the network slow?
Situation: Users report slow applications or unstable performance.
Solution: Compare traffic volumes, major flows and changes over time.
Benefit: Identify likely causes and focus troubleshooting.
Which device was behind a translated address?
Situation: An investigation starts with a public address used by multiple internal devices.
Solution: Correlate NAT records using timestamps, addresses and ports, where these records are available.
Benefit: Trace activity back to the relevant internal endpoint.
Where will we need more capacity?
Situation: Investment decisions rely on partial information.
Solution: Evaluate utilisation trends and prepare understandable reports.
Benefit: Plan capacity using evidence from actual operation.
Retrospective investigation depends on suitable data sources, accurate timestamps and sufficient retention. We help define what to collect, how long to retain it and who needs access.

Frequently asked questions
What data do we need?
It depends on the question. Network traffic records, system logs and monitoring outputs may be relevant. We assess whether they contain the detail needed.
Can analysis help with performance problems?
Yes. Traffic patterns and changes over time can help identify where to focus troubleshooting, subject to the sources available.
Do we need a new tool?
Not necessarily. We first review what your current systems already provide and identify any gaps.
How does analysis differ from monitoring?
Monitoring shows what is happening and can alert you to changes. Analysis investigates the context, relationships and possible causes.
Prepare for a consultation
Describe the problem, the systems involved and the kinds of data available. Please do not include sensitive records in the contact form; we will agree an appropriate way to work with them.
