Sentinel

Protect your infrastructure at the source

Automated attacks — brute force, scans, malicious bots — strike constantly and expose your services to real risks.

Sentinel protects your infrastructure close to the system, combining two complementary approaches: preventive blocking of known threats and real-time behavioural detection.

Everything runs autonomously, with no external proxy, no third-party dependency — your data stays on your infrastructure.

How it works

• 1
  Pre-filtering RBLs and IP reputation block known attackers before they interact with your services. No resources wasted on identified malicious traffic.
• 2
  Behavioural analysis System and application logs are analysed continuously to detect suspicious behaviour: brute force, scans, resource abuse, abnormal patterns.
• 3
  Event correlation Signals are cross-referenced to identify complex, coordinated attack patterns that individual detection would miss.
• 4
  Automated response Once a threat is confirmed, blocking is applied immediately — network rule, dynamic filtering — without waiting for human intervention.

What Sentinel protects

• Web (HTTP/HTTPS) Exposed web applications, reverse proxy — protection against bots, aggressive scraping and application-layer attacks.
• SSH Remote system access — detection and blocking of brute force attempts before any compromise.
• APIs Exposed services and application endpoints — protection against abuse and targeted attacks on your interfaces.
• Internal services Your entire stack, not just the web perimeter. Sentinel protects all exposed services, whether or not they are accessible from the internet.

Full observability

Every decision made by Sentinel is logged: detected events, blocked IPs, identified threat sources. You have real-time visibility into your infrastructure’s security activity — no black box.

Availability

Sentinel is included in every Heavy Mind managed IT contract. It is also available as an add-on on Monitoring.
