Automated blocking
Respond to repeated hostile activity with enforcement rules, including environments behind common proxy and load-balancing setups.
Qytherion · Sentinel
See hostile activity. Respond before it becomes background noise.
Sentinel combines lightweight monitoring on your infrastructure with cloud-based threat analysis to identify abuse, scanning, and repeated hostile behavior—and help enforce protections where they matter.
Server monitoring
Threat analysis
Automated blocking
Protection designed to stay operational.
Persistent rules
Maintain deployed protections across normal server operation and restarts.
Threat intelligence
Use broader signal correlation to identify patterns that may be difficult to see from an individual server alone.
Managed onboarding
Sentinel deployments can include setup, baseline configuration, and assistance connecting the monitored environment.
Security signals instead of indiscriminate log export.
Sentinel is designed around compact security signals rather than requiring complete log archives to be continuously exported for analysis.
Efficient monitoring
Capture the information needed to understand suspicious activity while limiting unnecessary data movement.
Cloud analysis
Run heavier threat analysis outside the monitored server.
Security briefings
Higher-tier deployments can turn security activity into clearer summaries for operators reviewing the environment.
Choose protection for the size of your environment.
