Internal Network Penetration Test

Internal Network Penetration Test

An internal network penetration test of your internal infrastructure identifies vulnerabilities that may be exploited by a malicious insider or malware.

Malicious employees, opportunist hackers, social engineers and malware all pose a significant threat to your organisation if they have been able to gain a foothold on your internal network infrastructure. If a malicious user has gained physical access to the internal network of an organisation, the impact can be devastating and will often be the precursor to a large-scale security breach.

A penetration test of your internal network infrastructure provides you with a full and complete understanding of the vulnerabilities that are present, which may be exploited by a malicious user or malware. Our experienced, CREST accredited penetration testers are skilled in identifying the types of vulnerabilities that may be exploited by a malicious user who had managed to gain unauthenticated network-level access to your environment.

How a test works

Using a combination of automated and targeted manual testing, our consultants will inspect your internal network infrastructure to identify vulnerabilities that could be exploited by a malicious user.

Usually, the ultimate goal of an attacker is to obtain Domain Administrator rights on the corporate Windows Domain. During our assessment, we use the latest techniques and attack vectors that an attacker is likely to use in identifying vulnerabilities, before exploiting vulnerable services which could allow for a full Domain compromise.

We validate all identified vulnerabilities to reduce the likelihood of “false positives” and to investigate the level of access that could be achieved if the vulnerability were to be exploited by a malicious user.

Engagement prerequisites

  • A signed & completed Testing Consent Form
  • List of internal IP addresses/networks to be tested.
  • If network segregation testing is to be performed, we will need the IP address ranges that you would like us to ensure are segregated from the wireless network.
  • Ability to connect our test appliance into the core network.
  • Ensure that any Intrusion Prevention Systems have been disabled or Hedgehog’s IP range ( to is white-listed for the duration of the test

Engagement deliverables

Engaging with Hedgehog Security for your internal infrastructure penetration test will provide you with the following:

Pre-engagement support

Prior to your test commencing, our penetration tester(s) will discuss the scope of work with you, so that a full understanding is obtained of what your Internet-facing network services are used for. This not only allows the test to run more efficiently but also allows the discovered vulnerabilities to be rated more accurately in terms of risk.

During the testing phase, our consultant(s) will engage directly with you – notifying you of any critical vulnerabilities that may be present within your infrastructure or any evidence in our results that may indicate a security breach may have already taken place.


Once the penetration test has been completed, you will be provided with the following:

Comprehensive Technical Report

Our clear & concise reporting format contains an Executive Summary that can be understood by all members of your organisation – including individuals who may be in management or non-technical roles. All vulnerabilities contain a sufficient level of technical detail, so that your development team and systems administrators can quickly pinpoint the root cause of the vulnerability and apply the recommended course of action.

Technical References

Where applicable, we provide additional reference URLs for each vulnerability, so that further information on the vulnerabilities can be obtained from reputable sources of technical information.

Risk-Based Approach with CVSS Scoring

A risk-based approach is used throughout the report and all vulnerabilities are scored in line with CVSS (Common Vulnerability Scoring System). This allows the contents of the report to be fed into your own internal risk assessments and allows a plan to be developed to address the vulnerabilities which present the highest risk to your organisation.

Secure & Encrypted Test Portal

Due to the sensitive content which may be contained in our test reports, all test reports are delivered to our customers through a secure test portal. Our portal is highly encrypted and is tested on a regular basis.

After Care

Once our engagement is complete and our final report has been delivered to you, our penetration testing team will remain available to you indefinitely for any questions you may have surrounding the report’s findings or our consultancy engagement with you.

We pride ourselves in partnering with our customers to provide ad-hoc security advice and to ensure that our engagement with you doesn’t simply end once the final report has been delivered.

We are committed to ensuring, that as our customer, you receive the utmost value out of our consultancy services and look forward to developing a long-lasting business relationship with you.

Conference Call

Once you have received our final report, you have the option of attending a conference call between the consultant(s) involved in delivering your project and individuals within your organisation who you feel would benefit from a more in-depth discussion of the report’s findings.

A conference call is suitable for both management and technical staff and provides you with the perfect opportunity to ensure that all vulnerabilities and their recommended course of action are fully understood by stakeholders and technical staff who may be tasked with applying the recommended course of action.

Free 14-Day Retest

With the testing being conducted remotely, we include a free retest of all issues identified in the report, providing they are mitigated within 14 days of the reporting being issued. This allows you time to take corrective action and ensures that your efforts have been successful in mitigating the vulnerabilities.
