Do you test network segmentation?

Yes. We specifically test whether segmentation actually prevents lateral movement or only looks good on paper.

What devices do you test?

We test routers, switches, firewalls, load balancers, and any network infrastructure devices in scope.

Do you need access to device configurations?

Not required, but configuration review alongside testing provides more comprehensive results.

Can you test from different network zones?

Yes. We can test from multiple starting points to validate segmentation from different perspectives.

Is this disruptive to network operations?

We use non disruptive techniques and coordinate with your team. Network testing can be scheduled during maintenance windows if needed.

How long does network infrastructure penetration testing take?

Most network infrastructure penetration testing engagements run 2 to 4 weeks. A small or single site network fits in 2 weeks; a multi site enterprise environment with complex segmentation, multiple zones, and a large device count typically needs 3 to 4 weeks. We confirm the exact timeline during scoping based on host and device count, segmentation depth, and the number of starting zones we need to test from.

Infrastructure Security

Secure Your Network Before Attackers Exploit It

Your network infrastructure is the backbone of your organization. Orasec’s network infrastructure penetration testing services identify weaknesses in servers, routers, firewalls, and connected devices. We uncover misconfigurations, exposed services, and lateral movement paths that attackers exploit, helping you prevent breaches, protect sensitive systems, and maintain regulatory compliance.

The Importance of Network Infrastructure Penetration Testing

Modern networks are complex, connecting servers, endpoints, cloud services, and third party systems. While designed for availability, many networks are misconfigured, over permissioned, or poorly segmented, leaving them exposed to lateral movement and attacks. Network infrastructure penetration testing identifies gaps before attackers exploit them, helping organizations secure routers, switches, firewalls, and network services while protecting sensitive data, reducing downtime, and ensuring regulatory compliance.

Networks Are Built for Availability, Not Security

Most network infrastructures prioritize uptime and connectivity over security. Default configurations favor convenience, and segmentation often looks ideal on diagrams but fails in real world scenarios. Network infrastructure penetration testing uncovers hidden misconfigurations, exposed services, and gaps in segmentation, helping organizations strengthen defenses, prevent lateral movement, and protect critical systems before attackers exploit weaknesses.

Our Network Infrastructure Penetration Testing Services

Orasec provides end to end network penetration testing to secure your internal and external infrastructure. Our testing covers all components with specialized sub services:

External Network Penetration Testing

Identify exposed services, misconfigured firewalls, and perimeter weaknesses that attackers can exploit.

Internal Network Penetration Testing

Simulate insider attacks, lateral movement, and privilege escalation across servers, endpoints, and internal systems.

Wireless & VPN Assessment

Evaluate Wi Fi networks, remote access gateways, and VPN configurations for vulnerabilities and misconfigurations.

Firewall & Router Testing

Assess rule sets, access controls, and security policies to detect gaps in perimeter defense.

Server & Endpoint Testing

Examine Windows, Linux, and network attached devices for patching issues, misconfigurations, and privilege risks.

Network Segmentation Review

Test VLANs, subnets, and segmentation controls to prevent lateral movement and isolate critical systems.

Cloud & Hybrid Network Assessment

Identify security gaps in cloud hosted servers, hybrid environments, and internal connections.

Automated & Manual Testing

Combine automated scans with hands on penetration tests for full coverage of all network components.

Test Your Network Segmentation Before Attackers Do

Once attackers gain a foothold via phishing, misused credentials, or exploited external services they move laterally through your network to access sensitive systems. Network infrastructure penetration testing reveals misconfigurations, segmentation gaps, and exploitable weaknesses, giving your security teams actionable insights to stop attacks before they reach critical assets.

Network Infrastructure Penetration Testing: Common Attack Techniques

Our network infrastructure penetration testing uncovers how attackers exploit network weaknesses, misconfigurations, and exposed services to gain unauthorized access:

Default Credential Exploitation – Attackers leverage unchanged admin credentials on switches, routers, and firewalls.
VLAN Hopping & Segmentation Bypass – Identify gaps in network segmentation that allow lateral movement.
Protocol Exploitation – Test SNMP, CDP, and LLDP for information disclosure that aids attackers.
Man in the Middle (MITM) Attacks – ARP poisoning and LLMNR/NBT NS exploitation to intercept network traffic.
Firewall & Access Control Bypass – Analyze rules to detect misconfigurations and bypass opportunities.
Router & Switch Compromise – Evaluate device vulnerabilities for traffic interception and manipulation.
Network Service Exploitation – Test TFTP, Telnet, and other unencrypted management services for exposure.

Network Infrastructure Penetration Testing: What We Assess

Orasec’s network infrastructure penetration testing services evaluate your entire network for security gaps, misconfigurations, and exploitable weaknesses. Our testing simulates real world attacks on routers, switches, firewalls, and network services to ensure your infrastructure is resilient.

Core Network Components Tested:

Routers

Configuration, ACLs, and routing protocol weaknesses that could allow traffic manipulation or privilege escalation.

Switches

VLANs, trunking, spanning tree, and segmentation controls to detect lateral movement paths.

Firewalls

Rule sets, NAT, and state tracking to verify effective perimeter enforcement.

Network Services

DNS, DHCP, NTP, SNMP, and other protocols for misconfigurations or abuse opportunities.

Secure Your Network Services

Network services like DNS, DHCP, NTP, and SNMP are often overlooked. Orasec’s testing ensures these services are hardened, reducing the risk of protocol abuse, data leakage, or service disruption across your infrastructure.

What Automated Tools Miss in Network Penetration Testing

Automated scanners often detect only standard vulnerabilities. Orasec goes further to simulate attacks that reveal real world gaps:
