If it’s exposed to the internet, it’s exploitable.

Your external network is the first thing attackers see — and often the easiest way in. At CyberGuards.ai, our network penetration testing services simulate real-world adversaries targeting your perimeter to uncover vulnerabilities before they’re exploited.

We don’t stop at surface scans. We validate, exploit, and prove what attackers can actually achieve.

Why Network Penetration Testing Matters

Every internet-facing service is a potential entry point. A single outdated protocol or open port can become the foothold attackers need to compromise your systems.

External networks are the origin point for the majority of successful breaches.
Legacy services and unpatched systems often remain exposed without detection.
Compliance standards such as SOC 2, PCI DSS, HIPAA, and ISO 27001 require network penetration testing as part of routine validation.

A network pen test ensures your perimeter is hardened against real-world threats — not just assumed secure.

What We Test

Open Ports & Outdated Services

FTP, RDP, SSH, SMB, and more.

Missing Patches

unpatched vulnerabilities in operating systems or services.

Weak Protocols

 insecure SSL/TLS, deprecated encryption, and default configurations.

Service Misconfigurations

unnecessary services, overly permissive firewall rules.

Chained Exploits

linking minor exposures into major compromises.

Every issue is manually validated with proof-of-concept exploits and mapped to business risk.

How It Works

Discovery

We map your external-facing IP ranges, domains, and services visible to the internet.

Exploitation

We simulate attacker behavior, exploiting weak services, chaining vulnerabilities, and testing lateral movement opportunities.

Reporting

You receive a detailed report with validated findings, severity ratings, reproduction steps, and remediation guidance.

Re-Testing

Once fixes are applied, we re-test — at no additional cost — to confirm closure.

Why Network Pentesting Is Different

Automated scans generate endless lists of open ports — but they don’t prove risk. Our network penetration testing services go further: we validate exploitability, chain vulnerabilities, and show you how attackers could pivot deeper into your environment.

FAQs

What's the difference between external and internal network pen testing?

External network pen testing attacks your public-facing assets from the internet, simulating an outside hacker. Internal testing assumes a breach has already occurred (e.g., a malicious insider or a phishing victim) and assesses how an attacker could move laterally to steal data or escalate privileges from within your network.
How deep does your internal network testing go?

We attempt to go as deep as possible. Starting with initial access, we test for privilege escalation, lateral movement across network segments, and ultimately, domain administrator compromise and data exfiltration, providing a full picture of your internal security posture.

How do you avoid causing network disruptions or downtime during testing?

We use safe, non-disruptive testing techniques and coordinate closely with your IT team. We avoid aggressive scanning on critical production systems and can schedule tests during maintenance windows to ensure business continuity is never impacted.

How do you handle testing in complex segmented networks?

 We meticulously map your network segmentation. We test the effectiveness of access control lists (ACLs), firewall rules, and network segmentation itself, identifying misconfigurations that could allow an attacker to bypass controls and reach critical segments.

What specific network elements does your infrastructure pen testing cover?

Our network pen testing covers firewalls, routers, switches, servers (Windows/Linux), network services, Active Directory environments, and wireless networks. We assess configurations, patch levels, and communication pathways for vulnerabilities.

Do you test for vulnerabilities in industrial control systems (ICS) or OT networks?

Yes, we offer specialized assessments for operational technology (OT) and ICS environments. These tests are conducted with extreme care to ensure safety and availability, following industry-specific protocols to identify risks in critical infrastructure.

What makes your approach to network pen testing more effective than automated scans?

Automated scans list potential vulnerabilities. Our expert-led infrastructure pen testing manually exploits these flaws, chains them together, and demonstrates the real business impact—such as gaining control of your domain—providing actionable evidence for remediation, not just a list of CVEs.
