External Infrastructure Penetration Testing
Your organization’s external infrastructure is often the first target for attackers probing your defenses. EJN Labs partners with you to secure your perimeter by identifying and validating critical vulnerabilities before they can be exploited. From internet-facing firewalls and VPN gateways to public cloud endpoints, our assessments uncover hidden weaknesses, deliver clear remediation steps, and help ensure your external attack surface is resilient and well protected.

Once the assessment is complete, we stay involved to help interpret results and verify fixes through optional re-testing.
Securing Your External Infrastructure
External infrastructure penetration testing simulates real-world attacks against your publicly accessible assets. This process is essential for preventing initial compromise, data theft, and service disruption.
Exposure Analysis
We map your public IP ranges, DNS records and cloud endpoints to identify exposed services. This includes checking firewall rules, VPN gateways, remote management interfaces and public cloud configurations.
Active Exploitation
We attempt controlled exploits against identified targets, testing for vulnerabilities such as misconfigured firewalls, unpatched services, weak TLS settings and default credentials to confirm real-world risk.
Combining exposure analysis with active exploitation testing provides a thorough understanding of your external attack surface, covering both visibility and exploitability.
External Infrastructure Security Assessment
Network Reconnaissance & Enumeration
Gather information on IP ranges, open ports, DNS entries and service banners to build an accurate map of your external footprint.
Perimeter Firewall & VPN Testing
Verify rule sets, ACLs and VPN configurations to ensure only intended traffic is allowed into your network.
Web & Application Server Hardening
Test internet-facing servers for missing patches, directory listing, default credentials and insecure service configurations.
Network Services & Protocol Analysis
Examine services such as SSH, RDP, SMB, SNMP and DNS for weak authentication, exposure of sensitive information and susceptibility to known exploits.
TLS & Certificate Validation
Check SSL/TLS implementations for weak ciphers, expired or self-signed certificates, missing HSTS and vulnerability to man-in-the-middle attacks.
Cloud Endpoint & API Exposure
Assess public cloud services like load balancers, storage buckets and management APIs for misconfigurations that could leak data or grant unauthorized access.
Wireless & Remote Access Security
Evaluate secure configuration of wireless gateways, VPN concentrators and remote desktop gateways to prevent credential theft and unauthorized entry.
