Network Penetration Testing Services

In a network penetration test, your network infrastructure is security tested using a variety of techniques from several vantage points, both external and internal. We test connected network devices including servers, laptops, storage drives, printers, network appliances, and even your web applications.

We look at how those components operate and communicate, who has access to them, and more. From this, we will be able to determine the security posture of those assets, as well as your network. We will determine where the most important vulnerabilities exist, which ones are most likely to be exploited by threat actors, and what actions should be taken to remediate these risks.

IoT Testing Services

The proliferation of connected devices has made the Internet of Things (IoT) a prime target for cyber threats, particularly for building botnets used in large-scale Distributed Denial of Service (DDoS) attacks.

We offer extensive IoT testing services to evaluate and ensure the security of smart devices across various sectors, including domestic, industrial, and automotive applications.

IoT security testing is crucial for any device that connects to a network, especially those designed for easy, 'plug and play' use, as these often have suboptimal security configurations.

Our expert testing focuses on the full attack surface, including hardware, firmware, applications, networks, and encryption, providing you with high-level management reports and detailed technical findings to improve device security. This thorough approach ensures that connected devices are secure against emerging threats.

External Infrastructure Penetration Testing

External Infrastructure Penetration Testing aims to assess the security of your external-facing systems, networks, and applications. This includes anything accessible from outside your internal network.

By conducting external infrastructure penetration testing, organisations can identify and address security weaknesses before they are exploited by malicious actors, thereby reducing the risk of data breaches, financial losses, and damage to reputation.

ASV Scanning

Approved Scanning Vendor (ASV) services are crucial for organisations handling payment card data, as they ensure compliance with the PCI Data Security Standard (DSS) by conducting quarterly external vulnerability scans. These scans identify potential security vulnerabilities, such as malware and breaches, within your Cardholder Data Environment.

We offer comprehensive scanning services aligned with PCI DSS requirements to help safeguard your data. Our ASV services go beyond standard automated scans by manually validating vulnerabilities to eliminate false positives and providing real-world remediation advice. Our team of qualified ASV professionals manages and schedules all quarterly scans, working closely with your security team to ensure ongoing PCI compliance and to address any issues swiftly and effectively.

Firewall Security Testing Services

Firewall security testing is essential for assessing the security and configuration of your organisation's firewall, which acts as the primary defence between your internal systems and the internet. As firewalls have evolved to include functionalities like VPNs, DLP filtering, and HTTP proxying, they also present new risks and vulnerabilities.

Our expert firewall testers conduct thorough assessments of your firewall's rule base, published services, and security protocols to identify and mitigate potential threats.

In addition to testing, we perform comprehensive firewall protection security audits, comparing your firewall’s configurations against industry best practices. This involves identifying weak protocols, insecure rules, and data leakage risks using advanced tools and scripts.

Active Directory

Most enterprise networks are managed by Windows Active Directory and store sensitive data. An attack that successfully compromised Active Directory would have significant ramifications for any organisation.

Our team of CREST-certified internal penetration testers review the configuration of your Active Directory to identify any insecure practices or attack vectors that could be exploited by a malicious agent.

Hybrid Testing

A hybrid environment is the term used when Microsoft Azure AD is incorporated into existing on-premises Active Directory. A compromise of on-premises Active Directory could lead to the compromise of Azure AD and vice-versa.

Our experts assess the configuration of your Azure AD and Active Directory looking for misconfigurations that could be exploited by an attacker. Focus is placed on attack paths that could lead to the compromise of Azure AD Connect, a high-value target with high privileges both on-premises and within the cloud.

Wireless Device Penetration Testing

We offer expert wireless device testing as a key component of internal onsite penetration tests, specialising in assessments against common 802.11 (WIFI) protocols.

Our testing covers both infrastructure and client devices, simulating real-world attacks to identify vulnerabilities. Our methodology includes on-site assessments for accurate threat simulation, focusing on various wireless environments such as unencrypted WLANs, WEP, WPA/WPA2, LEAP, and 802.1X networks. Additionally, we consider the risks posed by home wireless setups that might affect corporate security, offering adaptable, consultancy-driven tests to manage your WIFI security risks effectively.

FAQs

How will you tell me what the findings of my penetration test are?

We are communicative and consultative. During the engagement, we’ll periodically update you with the findings so far – both positive and negative. When we identify critical severity flaws, we will let you know immediately. At the end of the engagement, you receive a summary of all findings.

Will you help me to remediate vulnerabilities identified during the penetration test?

We will give you custom remediation guidance for every vulnerability that we identify during the test. If you have constraints, we work with you to understand those and propose an appropriate solution to any given vulnerability.

What is black box testing?

In a black box test, clients do not provide information about their infrastructure other than a URL or IP, or in some cases, just the company name. Black box penetration tests provide a simulation of how an attacker without any information, such as an internet hacker or a nation-state-sponsored attacker, could exploit the environment.

What is white box testing?

White box penetration testing is almost the opposite of blind/black box penetration testing. Penetration testers are given access to the source code and relevant design documentation which applies to the application being tested. Penetration testers can perform static testing using source code analysers to identify vulnerabilities. They are then able to compile the application and run it within a sandboxed environment, making use of dynamic testing using debuggers and common application testing tools. As a result, white box testing offers one of the highest levels of technical assurance.

What is grey box testing?

A grey box test is a blend of black box and white box testing techniques: In grey box testing, clients provide snippets of information to help with the testing procedures. This results in added breadth and depth, along with wider testing coverage than black box testing. Grey box penetration tests provide an ideal approach for clients who want to have a cost-effective assessment of their security posture.
