External Infrastructure Penetration Testing is designed to identify and exploit vulnerabilities within your public-facing systems, ensuring robust protection against potential threats.
Proactive Vulnerability Detection
Identify security gaps in your external systems before attackers exploit them. Penetration testing ensures your defences are ahead of evolving cyber threats.
Strengthened Security Posture
Gain actionable insights to prioritise remediation efforts and enhance the overall resilience of your public-facing systems.
Real-World Threat Simulation
Experience how your systems would hold up against genuine cyber-attacks, providing a practical assessment of your organisation's readiness to handle real-world threats.
Compliance and Assurance
Meet industry standards and regulatory requirements such as PCI DSS, ISO 27001, SOC 2, and GDPR while demonstrating a commitment to protecting sensitive data and systems.

External Infrastructure Penetration Testing: The CyberLab Approach
The way we structure our Pen Tests aligns closely with the steps taken by bad actors to target and compromise your systems. We replicate the approach of real-world adversaries to simulate and evaluate how your systems and processes respond to a cyber attack.
One of our CREST, CHECK, and Cyber Scheme certified consultants will work with you to define the scope of the engagement and ensure that our tests will fulfil your requirements.
Your assigned consultant will gather information on your organisation, including:
- IP addresses of websites and MX records
- Details of e-mail addresses
- Social networks
- People search
- Job search websites
This information will assist in identifying and exploiting any vulnerabilities or weaknesses.
Within the Threat Analysis stage we will identify a range of potential vulnerabilities within your target systems, which will typically involve a specialist engineer examining:
- Attack avenues, vectors, and threat agents
- Results from Research, Reconnaissance and Enumeration
- Technical system/network/application vulnerabilities
We will leverage automated tools and manual testing techniques at this stage.
Once we have identified vulnerabilities, we will attempt to exploit them in order to gain entry to the targeted system.
There are three phases to this stage:
- Exploit – use vulnerabilities to gain access to a system, e.g. inject commands into an application that provide control over the target.
- Escalate – attempt to use the exploited control over the target to increase access or escalate privileges to obtain further rights to the system, such as admin privileges.
- Advance – attempt to move from the target system across the infrastructure to find other vulnerable systems (lateral movement) potentially using escalated privileges from target systems and attempting to gain further escalated privileges and access to the network.
Your Penetration Test Report will detail any identified threats or vulnerabilities, as well as our recommended remedial actions. Threats and vulnerabilities will be ranked in order of importance.
The report will also contain an executive summary and attack narrative which will explain the technical risks in business terms. Where required, we can arrange for your CyberLab engineer to present the report to the key stakeholders within your organisation.
The report will provide information on remedial actions required to reduce the threats and vulnerabilities that have been identified.
At this stage, we can provide you with the additional consultancy, products, and services to further improve your security posture.

ISO 27001 is a globally recognised framework for managing information security risks. While penetration testing is not explicitly required, it plays a crucial role in meeting the standard’s risk assessment requirements by identifying weaknesses in systems and strengthening security controls.

Internal vs External Penetration Testing
| Internal Penetration Testing | External Penetration Testing | |
|---|---|---|
| Objective | Assess the security of internal systems, identifying vulnerabilities an attacker with internal access could exploit. | Assesses the security of externally accessible systems to identify vulnerabilities an attacker on the internet could exploit. |
| Scope | Internal assets such as servers, workstations, network devices, and internal applications. | Covers internet-facing assets such as web servers, VPNs, email servers, cloud services, and firewalls. |
| Access Requirements | Conducted via VPN or on-site, assuming the attacker already has internal network access. | Conducted remotely from an external perspective, simulating an attacker with no internal access. |
| Common Attack Method | Involves techniques such as network enumeration, privilege escalation, lateral movement, and exploitation of internal services and applications. | Includes scanning for open ports and services, testing authentication mechanisms, identifying misconfigurations, and exploiting external vulnerabilities. |
| Defensive Testing | Evaluates internal segmentation, endpoint security controls, and detection capabilities. | Assesses firewall rules, intrusion detection systems, and the exposure of services to the internet. |
| Outcome | Identifies risks that could be exploited by insider threats or compromised internal devices. | Highlights vulnerabilities that could lead to unauthorised access or data exposure from the outside. |
CREST, CHECK & Cyber Scheme Certified
CREST (the Council of Registered Ethical Security Testers) is an international accreditation with a strict Codes of Conduct and Ethics. CHECK is the Government-backed accreditation from the National Cyber Security Centre (NCSC) which certifies that a company can conduct authorised penetration tests of public sector systems and networks.
All our penetration testers are certified by CREST, with senior consultants certified by CREST to the highest CCT Level. Our testers are also either CHECK Team Leaders (CTL’s) or Team Members (CTM’s).
Security testers that pass the Cyber Scheme exams demonstrate ‘competence and skill at the highest levels’ as defined by the National Technical Authority for Cyber Security (NCSC).
Our team have decades of combined experience and take pride in operating at the highest level of the industry – conducting a broad range of government and commercial tests – and always aim to go the extra mile.
