Test Your Systems from an Attacker's Perspective with External Network Security Assessment
With İnvekor External Network Security Assessment, we examine your internet-facing IP blocks, domains, and services from an attacker's perspective, identifying and prioritizing critical vulnerabilities and reporting them with an actionable remediation plan.
We scan everything visible from the outside for you
The goal is to uncover the attack surface presented by all your internet-facing assets and identify vulnerabilities that could lead to data breaches, service disruptions, or reputational damage.
IP & Port Discovery
We perform comprehensive port scans across your external IP ranges to identify unexpected open services, forgotten test systems, and risky ports.
Service & Vulnerability Analysis
We correlate running service versions with known vulnerability databases and report exploitable weaknesses based on their priority.
Firewall & NAT Controls
We verify that your firewall, VPN, and NAT rules do not expose unnecessary services and identify misconfigurations.
Web Application Attack Surface
We assess your externally exposed web applications using basic OWASP Top 10 controls and weak authentication scenarios.
Authentication & Access
We identify weak password policies, default accounts, publicly accessible administrative panels, and missing 2FA protections.
Auxiliary Services & Hidden Exposure
We identify FTP, legacy protocols, test environments, misdirected subdomains, and other elements that expand the attack surface.
We conduct the external network security assessment step by step and in a controlled manner
The entire process is planned to avoid impacting your business continuity. Throughout the assessment, we maintain transparent communication with both your technical teams and management.
Discovery & Scope Definition
Your external IP blocks, domains, and critical applications are identified. The test depth and testing window are planned together.
Automated Scanning & Manual Verification
Discovery is performed using professional vulnerability scanning tools, and the resulting findings are manually verified by our expert team.
Risk Analysis & Prioritization
Vulnerabilities are evaluated based on impact, exploitability, and business criticality; they are classified as Critical / High / Medium / Low.
Reporting & Action Plan
An executive summary, technical report, and actionable remediation list are provided. If desired, we can conduct a workshop with your teams based on the report.
We test your external network with field-proven expertise
Our teams have years of hands-on experience with firewall, IPS, VPN, and enterprise network projects. We evaluate your external network security not merely as a "scan output," but through real-world attack scenarios. This ensures that every finding in the report is presented together with its potential impact on your business.
- Findings that can integrate with SIEM, SOAR, and log infrastructures
- Recommendations aligned with KVKK, ISO 27001, and regulatory requirements
- Collaborative approach with network, security, and systems teams
- Action-oriented remediation plan, not just issue identification
