Verify security with expert-led infrastructure penetration testing services
Let’s break it before hackers do! Our infrastructure penetration testing services use the same tools and techniques as the world’s most dangerous bad actors. We deliver a clear view of vulnerabilities that can’t be uncovered any other way.

Let's talk
Cybersecurity Services trusted by 500+ organizations and growing!
NuHarbor conducted a web application penetration test on a few of our edge applications. They discovered many configuration weaknesses including insecure direct object reference (IDOR). They notified us immediately and offered advice on how to fix it. Their skilled engineers provided step-by-step assistance and retested to ensure that this critical vulnerability was fixed.

Wifi. Yeah, that's an unfamiliar animal to deal with. We hired NuHarbor to test the wireless networks we provide for our employees and customers to access store services. NuHarbor came onsite and set up their "toolkit" with antennas sticking out all around. They were able to setup a rogue access point, mimicking our access points, and users unknowingly logged on. NuHarbor initiated an evil twin attack to capture and inject packages into the network stream between user computers and other systems and then delivered findings so we could educate and curve our user behavior.
Director
Retail Business
NuHarbor performed an external penetration test on our networks and alerted us to critical vulnerabilities. They let us know what the affected response might be from the host before they tried to exploit it. We were updated twice a day which was super helpful to me and my staff. They also provided great remedial guidance they helped us quickly correct vulnerabilities.
IT Director
Hospitality Company
NuHarbor waged a phishing campaign against our employees by mirroring a realistic payroll website that we use in our company. The NuHarbor engineers captured several IR administrators' credentials. With domain administrator access, they were able to compromise our whole domain within 20 minutes of starting the phishing campaign. We had the opportunity to show our leadership how pertinent it is to implement better user account practices, MFA, and improved use security awareness training and build the funds into our annual IT security budget.

We make it easy to test your defenses
There’s no such thing as a standard infrastructure penetration test or vulnerability scan. We work with you to plan offensive services that flex to your business needs and can be executed in as little as one week.
- Collaborate with expert engineers with years of experience in both public and private sectors.
- Receive tailored testing that balances cost and coverage without compromising quality or disrupting business.
- Gain visibility into exploitable vulnerabilities and get actionable takeaways for remediation.
- Access evidence-based reporting to inform security strategy, prioritization, and spending for better protection.
We’re the good hackers for hire.
Perimeter infrastructure isn’t as porous as it used to be. Most infrastructure security threats stem from misconfiguration and human oversight. Automated testing can’t find these common errors. Our approach includes human-based planning to simulate actions of a human bad actor.
Intelligence Gathering
We start by understanding your systems. A security engineer identifies and fingerprints live hosts and starts probing. We establish the network topology and confirm what operating systems and available services are present. We verify what access control mechanisms are in place and any core interactions between systems.
Inventory Vulnerabilities
Our security engineers use known vulnerabilities to identify potential entry points into a system. These entry points include legitimate services such as HTTP, FTP, SMTP mail exchangers, DNS, IMAP/POP, and file sharing services.
Network Topology
We identify the vulnerabilities present. These relate to network configuration, design principles, and protocol-specific characteristics. Testing for these attack paths utilizes spoofing techniques and protocol-specific tests. A security engineer may exploit fragmentation, trust relationships, protocol encapsulation, routing tricks, and implementation flaws.
Misconfiguration and Backdoor Tests
We confirm if the systems are correctly configured and scan the network for hidden backdoors. A security engineer attempts to exploit both.
Authentication and Access Control Schemes
We attempt to subvert authentication and access control mechanisms using dictionary and brute force attacks on reusable passwords, exploit authentication schemes, attempt social engineering, and review your contingency plan procedures for flaws.
White Box, Black Box, or a Combo
Our infrastructure penetration testing services include white, black, or gray box methodologies. White box testing gives you maximum coverage to ensure critical assets are tested. Black box testing simulates the attacks from a cyber criminal using only publicly available information. A gray box test finds the balance of testing defenses while ensuring critical asset coverage.
Overcome resource and expertise challenges with infrastructure penetration testing services
Organizations are struggling with the challenge of protecting digital assets due to continual and changing threats, complex tools, and limited resources. Common challenges to managing an effective security operation include:
- Adversaries operating 24/7, but you are closer to 8/5
- Spending too much time on too many tools
- Struggling to investigate incidents with quick responses
- Dealing with the high cost of training and retaining staff
- Balancing internal division of labor challenges related to administration and development
- Effectively communicating cyber risk to non-technical stakeholders



Cybersecurity testing is not an extra. It’s a necessity.
Expert-led testing by a reputable third-party is an investment in improved security and stability. External attackers succeed because they approach your systems in ways that you cannot expect. We bring that perspective and experience, ranking all findings for impact and ease of remediation so you can improve your security and resolve issues faster.
