Detect cyberattacks in minutes — not after the damage is done
Round-the-clock security monitoring
Security information and event management, log analysis, anomaly detection and immediate incident response to security incidents.
Anonymized reference caseFinancial services provider · Frankfurt, 110 employees+
Starting point
NIS2 obligation to implement security monitoring, no log management so far, no incident response process.
Solution & result
SIEM deployment with integration of all log sources, anomaly detection, a defined incident response playbook and 24/7 monitoring.
NIS2 compliance achieved, first attack attempt (credential stuffing) detected and blocked within 4 minutes, audit passed.
On average, attacks take 197 days to be discovered — far too long
- Without monitoring, you only notice a breach once data has been encrypted or stolen
- Firewall logs, server logs, AD logs — all separate, and nobody reads them systematically
- NIS2 and DORA require the implementation of security monitoring — with the risk of fines
A central SIEM that brings all logs together and detects anomalies instantly
- All log sources in one system: firewall, servers, cloud, endpoints — correlated and analyzed
- AI-powered anomaly detection recognizes even unknown attack patterns
- A clear incident response process: who gets alerted, and what happens in the first 60 minutes
Scope of services
What SIEM & 24/7 Monitoring does for you
SIEM Implementation
Setup of a central security platform for collecting and analyzing logs from all IT systems.
AI-Powered Anomaly Detection
Intelligent detection of unusual activity in real time — even with novel attack methods.
Incident Response
Immediate alerting and defined response processes for detected security incidents.
Log Management
Central collection, storage (at least 1 year) and analysis of all system and security logs.
24/7 Monitoring
Round-the-clock monitoring by our Security Operations Center — including weekends and public holidays.
Security Reporting
Monthly reports covering all security-relevant events, trends and recommendations.
Approach
How we work
Requirements Analysis
Definition of the systems to be monitored, data sources and alerting thresholds.
SIEM Deployment
Installation, integration of all log sources and configuration of the rule set.
Tuning & Optimization
Fine-tuning of detection rules to minimize false alarms while maximizing detection rates.
Ongoing Monitoring
24/7 operation with clear escalation paths, reporting and regular reviews.
The SIEM delivered immediately at the first real incident. A credential stuffing attack was detected and stopped within 4 minutes — without it, it might have gone unnoticed for days.
Detection Time
197 days or 5 minutes
That is the difference between companies without and with SIEM. 197 days — that is the average time to detect an attack without security monitoring.
Without SIEM
Attackers had 197 days of undetected access — data exfiltrated, backdoors installed, network mapped.
With SIEM (Clouderio)
Alert in under 5 minutes, containment in under 30 minutes — before damage occurs.
Log Sources
All sources, one central picture
Attacks always involve multiple systems — an isolated log event looks harmless; only in the context of all sources does the attack become visible. That is exactly what SIEM provides.
Windows Event Logs
Login events, processes, registry changes
Linux Syslog
System events, authentication, cron jobs
Firewall Logs
Fortinet, Sophos, Palo Alto, Cisco
Cloud Trails
Azure Activity Logs, AWS CloudTrail
Microsoft 365
Audit logs, Defender, Exchange, Teams
Active Directory
Logins, group changes, password resets
Endpoint Security
EDR alerts, malware detections, isolations
Network Devices
Switches, routers, WLAN controllers
NIS2 mandates security monitoring
Affected companies must implement security monitoring and incident response processes. Fines: up to €10 million or 2% of global annual revenue for essential entities.
NIS2 Compliance
How SIEM fulfills NIS2 requirements
SIEM is not a nice-to-have — it is the technical foundation for most NIS2 security requirements.
Incident Response
What happens when an alert is triggered?
No guesswork. No chaos. A defined playbook — everyone knows what to do in the first 60 minutes after an incident.
Alert triggered
SIEM detects anomaly, rule fires. Automatic classification by severity.
SOC assessment
Our security team evaluates the alert: real incident or false positive? Context analysis.
Escalation
If the incident is confirmed: your designated contacts are notified and the severity is communicated.
Containment
Immediate measures: lock compromised accounts, isolate affected systems, stop spread.
Incident Report
Complete forensic analysis: what happened? How did the attacker get in? What was changed?
Frequently asked questions
Everything you need to know about SIEM & 24/7 Monitoring at a glance.
01Which log sources can the SIEM integrate?+
All common sources: Windows Event Logs, Linux syslog, firewall logs (Fortinet, Sophos, Palo Alto), Azure/AWS CloudTrail, Microsoft 365 audit logs, Active Directory, endpoint security products and network devices. Integration via syslog, API or agent.
02Is a SIEM mandatory for our company?+
NIS2 requires affected companies to have security monitoring and incident response processes. DORA applies to financial service providers. Even without a legal obligation, a SIEM is strongly recommended for companies with 50 or more employees.
03How long does a SIEM deployment take?+
From requirements analysis to the first productive monitoring typically takes 4–8 weeks. The first week already delivers initial insights from the log data.
04What happens when an alarm is triggered?+
We have defined escalation paths: automatic alerting, initial assessment by our SOC team, notification of your contacts according to severity. No alert flood — only alerts that require real action.
05How much does SIEM & 24/7 monitoring cost?+
SIEM deployment from a one-time investment of €8,000. Ongoing 24/7 monitoring from €990 per month, depending on log volume and environment size.
