Definition
What is SIEM?
SIEM (Security Information and Event Management) is software that collects security logs from servers, network devices, applications and cloud services, normalizes them and correlates events across sources to detect threats in real time. When a detection rule matches, the SIEM raises a prioritized alert, so security teams and SOC analysts can investigate the incident with full context from one place.
Attacks rarely show up in a single log. The brute-force attempt appears in the firewall, the login in the identity system and the privilege change on a server. Each event looks minor on its own; correlated, they describe an attack. SIEM gives the SOC that combined view and keeps the evidence for investigations and compliance reporting.
How SIEM works
1. Collect
Logs arrive from firewalls, servers, identity systems, databases and cloud services over Syslog, REST API, file collection and agents.
2. Normalize
Parsers turn each vendor’s format into common fields such as source IP, user, action and event ID.
3. Correlate and detect
Rules combine conditions, thresholds and time windows across sources, and threat intelligence adds context.
4. Alert and investigate
A prioritized alert opens with its related events, so analysts can investigate and respond.
Turn events into insights
From isolated events
to connected evidence.
Detect complex attack patterns by correlating events across multiple log sources. See the relationships between activities, assets and users to understand what’s really happening.
Connect multiple sources
Unify logs from your infrastructure, applications and cloud environments.
Recognize event sequences
Identify patterns and multi-stage attacks across time and sources.
Bring context to investigations
Link related events, users, assets and threat indicators.
Centralized security visibility
Your security operations.
In one workspace.
Collect, correlate and investigate security events across your entire environment from a single, unified platform.
- Servers
- Endpoints
- Firewalls
- Applications
- Cloud environments
Flexible detection logic
Detection logic
that fits your environment.
Collect, correlate rules based on event frequency, log patterns, field values and anomaly detection.
- Event frequency (e.g. repeated actions)
- Log patterns (e.g. failed logins followed by success)
- Field values (e.g. privilege changes, unusual locations)
- Anomaly signals (e.g. behavior deviations)
- Threat intelligence matches (e.g. known malicious IPs or domains)
Detection scenario
From failed logins to a privilege change.
The screens on this page show a common account takeover pattern. Here is how Logchase SIEM turns it from scattered events into one incident, step by step.
Taken one by one, these events are easy to miss: failed logins happen every day and group changes are routine admin work. Correlated by account, source IP and time, they describe an attack in progress, and the analyst has the evidence for the incident report from the start.

- 1
Repeated failed logins
Identity logs record a burst of failed logins (Windows event 4625) for one account, all from the same external IP address. A brute-force rule counts them against its threshold and time window.
- 2
A successful login follows
Minutes later the same account logs in successfully (event 4624). A correlation rule like the one shown above, five or more failed logins within ten minutes followed by a successful login, links the two and raises a detection.
- 3
The account gains privileges
Soon after, the account is added to a privileged group (event 4728 or 4732). On its own this can be routine; right after a suspicious login it is a strong signal, and the risk of the incident goes up.
- 4
Context is added
Threat intelligence checks the source IP against known malicious IPs, botnet activity, TOR exit nodes and brute-force sources, while firewall logs show what else that address reached.
- 5
One prioritized alert
Instead of dozens of separate events, the analyst gets one high-severity alert with the related firewall, identity and server events on a single timeline.
- 6
Investigate and respond
The analyst moves the alert to investigating, adds notes and opens an incident, then acts: reset or disable the account, block the IP and review everything the account did after the privilege change.

Capabilities
What’s inside Logchase SIEM.
Detection, context and investigation tools on top of centralized log management, in one platform.
Correlation rules
Build rules from field conditions, thresholds and time windows, combined with AND/OR logic and business-hours checks.
Rule templates
Start from ready-made detection templates, each mapped to MITRE ATT&CK techniques, and tune them to your environment.
Threat intelligence
ThreatPeak integration flags malicious IPs, botnet activity, TOR exit nodes and brute-force sources in incoming logs.
Risk scoring and anomalies
Risk scores and behavioral signals bring the incidents that matter to the top of the queue.
Alerts and incidents
Track each alert from open to investigating to resolved, add notes and manage incidents in one place.
File integrity monitoring
FIM events from Linux and Windows hosts appear next to your logs, with severity-based alerts.
Roles, tenants and HA
Role-based access control, multi-tenant setups and HA clusters, depending on the package.
Cloud or self-hosted
Run Logchase in the cloud or on your own servers with the Core, Advanced, Enterprise or Elite package.
What the rule templates detect
Account attacks
Brute-force attempts, successful logins after repeated failures and logins outside business hours.
Network threats
Port scans, sudden traffic spikes, unusually large transfers, suspicious DNS queries and lateral movement.
Malicious infrastructure
Traffic to and from IPs on threat intelligence lists, repeated contact with them and botnet C2 communication.
Web application attacks
SQL injection, XSS, path traversal and command injection, plus Log4Shell and Spring4Shell exploit attempts.
Credential theft
LSASS memory dumps, NTDS.dit shadow copies, credential extraction from the registry, Kerberoasting and DCSync.
Malware and system changes
Ransomware file extensions, PowerShell or CMD started from Office apps, configuration changes and stopped services.
Every alert keeps a reference to the events that triggered it, so the raw records in log management stay close at hand, and file integrity monitoring adds host-level evidence.
Choosing a SIEM
What to check when you compare SIEM tools.
SIEM solutions look alike on a feature list; the differences are in the details. These are the questions worth asking every vendor, with Logchase’s answers.

FAQ
SIEM FAQ
What is SIEM?
SIEM (Security Information and Event Management) collects security logs from many sources, correlates them, detects suspicious behavior and raises alerts, so security teams can see and investigate incidents from one place.
How does SIEM work?
Logs are collected and normalized, then detection rules and correlation link related events across sources. When a pattern matches, a prioritized alert is created and an analyst investigates it with full context.
What is the difference between SIEM and log management?
Log management collects, stores and searches logs. SIEM adds correlation, detection and alerting on top. Logchase provides both in one platform.
Can we tune detection rules to our environment?
Yes. Detection logic adapts to your environment and priorities: start from ready-made templates and change conditions, thresholds and time windows, reducing noise and surfacing the events that matter.
Is Logchase SIEM cloud-based or self-hosted?
Both options are available: cloud or self-hosted deployment. Self-hosted installations come in the Core, Advanced, Enterprise and Elite packages.
How is Logchase SIEM priced?
Pricing depends on the package, the number of log sources and the deployment model; EPS is unlimited in every on-premise package. Book a demo to get a quote for your environment.
