Investigate threats. Improve detections. Measure SIEM maturity.
Tier4Security brings threat intelligence, detection engineering, and SIEM maturity assessment into one practitioner workspace.
Threat Intelligence
Investigate an IP, domain, hash, or URL with an AI-assisted triage summary and suggested next steps. Connect the curated indicator feed to your security tools through STIX / TAXII 2.1.
Indicator investigation
198.51.100.24
IPv4 address
Investigation context
Repeated failed SSH sign-ins from a single source warrant further investigation. A suggested verdict guides triage; it does not confirm compromise.
- Observed activity
- Failed authentication
- Next step
- Correlate with successful sign-ins

Detection Engineering
Turn a log sample into an assessment of its security value, MITRE ATT&CK mappings, and detection queries for Microsoft Sentinel and Splunk. See what your data can help you detect.
From log sample to detection
Log sample · SSH authentication
10:42:01 sshd: Failed password for root 10:42:03 sshd: Failed password for root 10:42:05 sshd: Failed password for root
Brute Force · T1110
MITRE ATT&CK · Credential Access
Detection query

| where SyslogMessage has "Failed password"

| where Attempts > 10SIEM Maturity
Measure your SIEM across data architecture, detection engineering, automation, and governance. SEMF turns a self-assessment into a four-domain maturity profile, with a clear starting point for improvement.
