Benefits of Infrastructure Penetration Testing

An Infrastructure Penetration test uncovers vulnerabilities residing within your infrastructure and provides a detailed attack narrative to help evaluate the impacts of each finding.

Find vulnerabilities residing in IT systems, applications, or network components

▸ Each finding is documented with screenshots, and an attack narrative to illustrate the potential risk.

Protect access to sensitive information by finding weaknesses others overlook

▸ Go beyond a vulnerability assessment to identify the techniques attackers would take to breach sensitive information.

Stay compliant

▸ Fulfillment of compliance objectives includes: PCI DSS, ISO27001 and GDPR compliance

What Zeroday.PRO Offers

Our network penetration testing services identify, validate, and prioritize vulnerabilities on internet facing, internal and cloud-based IT infrastructure.

Internal Penetration Testing

Our security engineers approach the local area network as an attacker on the inside. We look for privileged company information and other sensitive assets. This involves incorporating a variety of tools, uncovering user credentials, and attempting to compromise servers, routers, proxies, user workstations, printers and any machine present in the network environment.

External Penetration Testing

Your perimeter network is attacked every day and even small external vulnerabilities can be damaging. External network penetration testing identifies vulnerabilities on infrastructure devices and servers accessible from the internet. Deliverables include attack narratives that illustrate how vulnerabilities can be used together in attack chains to have the greatest impact.

Wireless Network Pentesting

WiFi networks may be susceptible to a myriad of attacks. Our pentesting service helps identify exploitable security vulnerabilities of a WiFi network and simulate the attack actions that a real world attacker would carry out. In general, we will attempt to breach the wireless network through two different modes of attack: wireless architecture and wireless clients.

Our Network Security Testing Methodology

Zeroday.PRO Labs operates under a structured, repeatable methodology. We prioritize this concept in each engagement to make certain that our assessment is reliable, reproducible, and top-notch in quality. As such, our findings can always be verified by your team, before and after the remediation. To get these results, we are guided by the following steps:


This is where all requirements are gathered and goals are set. It’s where types of tests, forms, timelines and limitations are codified and agreed. We utilize our own SecurePortal to ensure that all of the required scoping documents are securely transmitted between the client and the company.



In this phase, we will utilise both Passive and Active Information Gathering. Our consultants will collect as much information as they can on the target, employing a myriad of OSINT (Open Source Intelligence) tools and techniques.



The assessment phase aims to check known vulnerabilities against the operating systems and services that have been identified as present in the network. Attempts are also made to exploit common operating system vulnerabilities to check the level of privileged access that can be achieved.



We have developed a comprehensive reporting format that provides optimal insight into our work. The summary lists the key findings along with the top ten recommendations for remedial action. A table of hosts is provided together with the total number of vulnerabilities identified at each severity level.



The full assessment report will be created and uploaded to our SecurePortal for review prior to scheduling a de-brief call. The call or meeting is an opportunity for you to discuss any major issues arising from the assessment with the lead consultant who will formally present the findings of the report.



We are happy to re-examine the security weaknesses to ensure that the defense mechanisms have been implemented correctly. This process activity is always free of charge.

Manual vs Automated Penetration Testing

We apply manual analysis, cutting-edge methodologies, the best pentesting software, and our unique pentest report generation tool.

Frequently asked questions about Network Penetration Testing

What does my organization gain from security testing its infrastructure?

Our team of consultants will ensure that we have done everything possible to evaluate the security defenses you have in place at your organization. It is impossible to assess how well an organization’s defensive measures are working, unless they have been tested to react the way a vendor has claimed they are intended to perform.

Our reports detail findings in an easy-to-read layout for executives, but also provide the necessary results, guidelines and suggestions that can help the technical staff mitigate the exploitable vulnerabilities found. This allows management to share results with all organizational stakeholders involved to address the weaknesses in all related operations.

What is the difference between internal and external security infrastructure testing?

External infrastructure testing is concerned with what services, protocols, and applications are being exposed to the internet, e.g. web servers, log-in portals. These systems are considered the most vulnerable, as the constant assault of attacks from external threat actors create a high level of risk to all exposed areas. The systems that are exposed must have flawless configurations focusing on hardening techniques.

The assumption with Internal infrastructure testing is that external threat actors have already penetrated external defenses to find a way inside or the threat is being sourced from an internal actor. The primary focus areas for this type of testing are lateral movement and privilege escalation. The goal of this type of testing is to identify how difficult it is for an internal attacker to move around the internal network and to discover what type of sensitive data may be obtained in the process. This is also an effective way to test the awareness of the defensive team by identifying how quickly it takes for a defensive team to discover the presence of an intruder and if they were able to isolate how the intruder gained access.

What information is needed to scope an infrastructure security test?

In most situations, our clients choose to identify a list of assets they want our consultants to focus on within the scope of the engagement. After the client has established this, they would simply contact our team to set up a meeting to go over the details.

What type of methodology is used for infrastructure security testing?

Zeroday.PRO consultants are trained to follow our own specialized security testing methodology based on industry standards primarily aligned with OWASP, NIST and PTES in order to ensure compliance with most regulatory requirements. The reason for this organizational-specific testing methodology is to create an effective attack plan that produces data results that are valuable, but also have a high-level of validity associated with them. Our consultants take the time to create proof of concepts (POCs) that are easy to understand and follow, but also show exactly how we came to the results, so our clients can use this information to mitigate the vulnerabilities and create a more secure infrastructure.

How long does an infrastructure security test take?

The time it takes an ethical hacker to complete an infrastructure security test depends on the scope of the test, including the number and type of systems, networks and applications.

What happens at the end of an infrastructure security test?

After each infrastructure security test, the ethical hacker(s) assigned to the test will produce a custom written report, detailing any weaknesses identified, associated risk levels and recommended remedial actions.

How much does an infrastructure security test cost?

The cost of an infrastructure security test is determined by the number of days our ethical hackers require to fulfil the agreed scope of the engagement. As part of the initial scoping process, a quote is produced upon completion and return of a short pre-evaluation questionnaire.
