Infrastructure Security & Hardening

Make your infrastructure a harder target.

Loopbacs secures Linux servers and production applications with layered hardening, firewall controls, WAF protection, intrusion detection, secure TLS and continuous visibility.

Security controls that work together.

There is no single security switch. Loopbacs builds multiple layers so one missed control doesn't become a complete compromise.

LAYER 01

Access Security

Reduce unauthorized access by strengthening remote administration and account-level controls.

SSH HardeningKeysUFWLeast Privilege
LAYER 02

Network Protection

Control exposed services and limit unnecessary network access to production systems.

FirewallPortsNetwork RulesRate Limits
LAYER 03

Application Protection

Inspect web traffic and block common application-layer attacks before they reach your application.

ModSecurityOWASP CRSNginxTLS
LAYER 04

Threat Detection

Detect suspicious behavior and security events with centralized security visibility.

LAYER 05

System Hardening

Strengthen the operating system baseline, reduce attack surface and keep systems maintained.

LAYER 06

Continuous Visibility

Monitor infrastructure health and security signals so issues are found before they become incidents.

Security assessment

Know where your infrastructure is exposed.

We review your server configuration, exposed services, access controls, web stack and security tooling, then turn the findings into practical remediation steps.

What we protect against

Practical protection for common infrastructure threats.

Security controls are selected around the real attack surface of your Linux and web infrastructure.

🔑

Unauthorized Access

Strengthen SSH, authentication and permissions to reduce the risk of compromised administrative access.

🌐

Web Attacks

Use ModSecurity and OWASP CRS to add an application-layer defense around internet-facing services.

🤖

Automated Abuse

Detect and respond to suspicious traffic patterns using CrowdSec and related controls.

🕵️

Suspicious Activity

Centralize security events with Wazuh so unusual behavior is easier to investigate.

📦

Unpatched Systems

Keep production servers updated and identify configuration gaps that increase exposure.

🔒

TLS & Configuration Risk

Review SSL/TLS and reverse-proxy configuration to improve the security baseline of public services.

Security technology stack

A security layer around your existing infrastructure.

We work with proven open-source technologies and integrate them into practical operational workflows.

🧱 ModSecurity + OWASP CRS

Web application firewall protection for common malicious request patterns.

⚡ CrowdSec

Behavior-based detection and collaborative blocking for hostile activity.

👁 Wazuh

Security monitoring, event visibility and host-level security analytics.

🔐 SSL/TLS

Secure HTTPS configuration, certificate deployment and expiry awareness.

🛡 UFW

Host-based firewall configuration and controlled network exposure.

📊 Prometheus + Grafana

Infrastructure health and operational visibility to complement security monitoring.

How security engagements work

Assess → Harden → Protect → Monitor → Improve.

01 / ASSESS

Discover

Map servers, services, access points and current controls.

02 / HARDEN

Reduce Risk

Fix configuration weaknesses and unnecessary exposure.

03 / PROTECT

Add Layers

Deploy firewall, WAF, detection and TLS controls.

04 / MONITOR

Observe

Collect security and infrastructure signals.

05 / IMPROVE

Maintain

Patch, review alerts and continuously improve the baseline.

Ways to engage

Security support that fits your stage.

Choose a focused security project or combine protection with ongoing infrastructure management.

Security Audit

For teams that want to understand their current security posture.

  • Infrastructure assessment
  • Configuration review
  • Security findings
  • Prioritized remediation plan

Managed Security

For businesses that want security controls maintained over time.

  • Security monitoring
  • Patch & maintenance
  • Alert review
  • Ongoing troubleshooting
  • Periodic security review
Secure your production environment

Let's find your biggest infrastructure risks.

Share your current environment with Loopbacs and we'll help identify practical security improvements without unnecessary complexity.
