External Network Penetration Test
Fortify Your Network Perimeter and Internet Exposed Systems
Your external network is the first line of defense—firewalls, servers, web applications, cloud assets and more. Unfortunately, nothing on the internet is left untouched. All it takes is a single misconfiguration or unpatched service to invite large scale reconnaissance, exploitation, or full breaches. These flaws can jeopardize your entire infrastructure. Aevora’s External Network Penetration Testing fortifies that frontline.
We simulate advanced threat actors on your public-facing assets, combining automated sweeps with manual human expertise to expose and uncover critical vulnerabilities. Ready to hold down the front line? Contact us today for a free consultation.
What is External Network Penetration Testing?
External Network Penetration Testing is an outward-facing ethical hacking simulation targeting your internet-exposed infrastructure—servers, VPNs, web apps, and more. We assess from an attacker’s remote vantage, without internal access, to reveal perimeter weaknesses. Our hybrid approach delivers exhaustive, non-disruptive coverage:
- Automated Testing: Tools like Nmap, Nessus, and Nuclei automate port scanning, service fingerprinting, and vulnerability enumeration—quickly pinpointing open doors like dangerous protocols and known software vulnerabilities across your IP ranges.
- Manual Testing: Aevora operators manually chain findings with custom payloads and evasion tactics—uncovering stealthy issues like firewall bypasses, SMTP open relays, breached credentials, cloud misconfigurations, or Remote Code Execution (RCE) vulnerabilities that scanners miss.
Our Methodolgy
At Aevora, we don’t do one-size-fits-all. Our penetration testing follows industry-leading frameworks like MITRE ATT&CK and NIST, tailored to your unique environment. Here’s how we deliver results:
- Scoping & Reconnaissance: We collaborate with you to define targets, rules of engagement, and business-critical assets—ensuring zero disruption to your operations. During this time we also discuss specific goals to see if you would like us to attempt to pivot into the internal network or compromise business accounts. Aevora operators will also perform passive reconnaissance using tools such as Shodan, and crt.sh during scoping to get a general intelligence perspective on the external network environment.
- Vulnerability Scanning & Enumeration: The majority of security firms will hand you a vulnerability scan and call it a day. This is especially true for external engagements. These companies lack intention and the attacker mindset. Aevora operators use automated tooling throughout the engagement, but they key difference is that we use automation to enhance manual efforts. Vulnerability scanning and enumeration is used to find the low hanging fruit and map out the attack surface of the external network.
- Exploitation & Proof-of-Concept : All exploitation is conducted in a safe and responsible way to avoid disruption to operations. The team also seeks to find realistic proof of concepts that easily demonstrate impact and include clear steps for reproducing.
- Post-Exploitation Analysis : We don’t stop after a vulnerability is found. Instantly the question, “What is the worst thing that could happen?” gets asked. Aevora operators seek to chain vulnerabilities and move around the environment for additional access.
- Comprehensive Reporting & Remediation Guidance : You’ll receive a detailed report with executive summaries, technical findings, risk ratings (CVSS-scored), and step-by-step fix recommendations. Plus, we offer re-testing at a discount to verify remediations.
All of Aevora’s operators possess the highly coveted OSCP certification and we also have more network tailored certifications such as the OSEP and PNPT. With Aevora you are getting the best and you can have confidence that every test is thorough, confidential, and compliant with standards like PCI-DSS, HIPAA, and GDPR.
Why Choose Aevora for Your External Network Pen Test?
In a sea of cybersecurity firms, Aevora stands out because we prioritize your success. Here’s what sets us apart:
- Adaptive and Capable: We have compromised a large number of external networks. From small companies to massive enterprises—we will find every angle and pry with precision and resilience. Aevora operators are required to remain knowledgeable on the latest security trends, tooling, techniques, and network security concepts.
- Rapid Turnaround: Most engagements are completed in 2-4 weeks. Importantly, we are flexible and are ready to work around the timelines that you require. Engagement length is primarily determined by the size of the external footprint and Aevora’s testing schedule.
- Transparent Pricing: Starting at $5,000 per week for standard engagements. While scoping, we will analyze the external network landscape and any specific custom goals established. Custom goals in some scenarios can impact engagement complexity. These details can fluctuate pricing as every external environment is designed differently and we strive to meet your key goals. We do not have hidden fees. Once you receive a quote, it accounts for everything from the kick-off call to the final out-brief where we share the report and discuss the technical narrative.
- Ongoing Partnership: Beyond the engagement, you will have access our threat intelligence feeds and quarterly health checks to stay ahead of emerging risks. This is completely free. We want to be your go-to experts year-round. We prioritize your success.
Who Benefits From Our External Network Pen Tests?
This service is essential for:
IT and Infrastructure Teams: Gain a clear understanding of your organization’s external attack surface. Our tests identify misconfigurations, exposed services, and other weaknesses that could be exploited by attackers. The insights we provide help teams prioritize remediation and implement long-term security improvements across network architecture and perimeter defenses.
Security Teams: Augment your internal capabilities with an external perspective. Our assessments uncover blind spots, validate existing defenses, and provide actionable data to strengthen your organization’s security posture.
Organizations Hosting Public-Facing Infrastructure: Whether you’re running VPN gateways, email servers, remote access tools, or cloud environments, we help ensure these assets aren’t entry points for threat actors. Regular testing is critical for maintaining a secure perimeter, especially as remote work and cloud adoption grow.
Heavily Regulated Industries: Meet strict compliance requirements such as PCI-DSS, HIPAA, and GDPR. Our penetration tests provide the necessary evidence and risk insights to satisfy auditors and regulators. If you have specific compliance requirements, be sure to let us know during scoping.
Companies Preparing for Funding, Acquisition, or Compliance Audits: Demonstrate a mature security posture to investors, acquirers, or auditors. A clean, professional penetration test report shows due diligence and builds confidence in your external network security.
Businesses of All Sizes: From startups hosting their first services online to enterprises managing a global infrastructure, every organization benefits from understanding and securing its internet-facing assets. Automated tools alone can’t catch everything—manual testing brings depth and context. Protect your external footprint, reputation, and customer trust.
