Purpose
When this assessment fits
Even with secure applications, underlying infrastructure vulnerabilities can provide attackers with a direct path into your network. This assessment focuses on evaluating the security posture of your externally reachable servers, Virtual Private Servers (VPS), cloud instances, and public-facing services. It is designed for organizations that need a rigorous review of their external network perimeter to identify open ports, exposed administrative panels, outdated services, and weak encryption protocols, ensuring that the foundation of their digital presence is solid.
What we review
- Public IPs and exposed services
- Open ports and service banners
- SSH exposure and configuration
- RDP exposure and configuration
- VPN exposure and encryption strength
- Hosting/control panel exposure (cPanel, Plesk, etc.)
- TLS/SSL configuration and certificate validity
- Web server exposure (Apache, Nginx, IIS)
- Firewall exposure and rule effectiveness
- Outdated service indicators
- Remote access risk
Common risks we help identify
- →Unnecessary services (e.g., databases, file sharing) exposed directly to the public internet
- →Remote access services (SSH, RDP) exposed without strong authentication or rate limiting
- →Weak TLS configuration (e.g., supporting deprecated protocols like TLS 1.0/1.1 or weak ciphers)
- →Publicly accessible control panels susceptible to brute-force or known exploits
- →Old or unsupported service versions containing known, easily exploitable vulnerabilities
- →Incomplete firewall restrictions allowing broader access than intended
Business value
- Secure Remote Access: Ensure that administrative access points are robustly protected against unauthorized entry.
- Harden Critical Infrastructure: Identify and eliminate vulnerabilities in the fundamental building blocks of your IT environment.
- Prevent Lateral Movement: Secure external entry points to prevent attackers from gaining a foothold and moving deeper into your network.
- Maintain High Availability: Prevent denial-of-service conditions or system compromises that could result in costly downtime.
Methodology coverage
Our methodology involves comprehensive port scanning and service enumeration across authorized IP ranges and hostnames. We analyze the configuration of discovered services, evaluate TLS/SSL implementations for cryptographic strength, and identify outdated software versions running on exposed ports. We manually verify findings to eliminate false positives and assess the real-world exploitability of identified vulnerabilities, providing clear, actionable hardening guidance tailored to your specific infrastructure.
What we need from you
- →Approved IP ranges or hostnames
- →Written authorization
- →Testing windows
- →Any restrictions on service probing
- →Emergency contact
Frequently asked questions
Do you perform internal network testing?
NYOXA LABS can scope internal network testing as a separate engagement. The default Infrastructure Security Assessment focuses specifically on externally reachable systems.
