Penetration Testing

Your external network is the most visible and targeted part of your digital environment. Every exposed service, application, or misconfigured system represents an open invitation to attackers searching for a way in.

External penetration testing simulates how a real-world adversary would attempt to breach your perimeter. Parabellum’s consultants use advanced tools and manual techniques to probe internet-facing assets, uncovering vulnerabilities in firewalls, VPNs, web servers, and remote access portals.

By going beyond automated scanning, we validate which flaws are exploitable and demonstrate the real-world impact of compromise. Findings are mapped to business risk, with remediation steps prioritised by severity and likelihood.

The outcome is clarity on your organisation’s true external risk posture and practical guidance to harden your defences against attack.

Internal (Assumed Breach) penetration testing simulates an attacker who has gained access to your internal network, whether through a compromised user account, malicious insider, or rogue device. Our consultants mimic these threats to uncover vulnerabilities in domain controllers, shared resources, internal applications, and misconfigured systems.This test validates segmentation, privilege escalation risks, and lateral movement potential. It shows you exactly what a threat actor could do after breaching your perimeter. With detailed findings and remediation guidance, Parabellum helps you harden your environment and reduce the risk of widespread compromise.

Wireless networks are a prime target for attackers because they extend your organisation’s perimeter beyond the physical walls of your buildings. A single misconfigured access point or weak encryption standard can allow unauthorised individuals to gain a foothold without ever stepping inside.

Parabellum’s Wireless Penetration Testing goes beyond simple vulnerability scans. Our consultants perform controlled, real-world attacks to evaluate how secure your wireless infrastructure truly is. We test encryption protocols, assess authentication methods, and look for rogue or unauthorised devices that could silently connect to your environment.

By emulating attacker behaviour, such as traffic interception, Evil Twin setups, and Man-in-the-Middle attacks, we reveal how intruders could exploit your wireless networks to capture credentials, access systems, or move deeper into your organisation. The results give you practical, prioritised actions to strengthen wireless security, protect sensitive data, and prove to stakeholders that your wireless environment can withstand modern threats.

Applications sit at the heart of modern business operations. They process payments, store personal data, and deliver services directly to customers. This makes them one of the most frequently attacked parts of your digital footprint and often the most difficult to secure.

Parabellum’s Web Application Penetration Testing is built to expose the vulnerabilities that matter most at the application layer. We go beyond vulnerability scans by applying a combination of deep manual testing and adversary-style thinking. Our consultants explore your application as an attacker would, testing not only for technical flaws but also for weaknesses in logic, workflows, and role boundaries.

Every engagement is tailored to your needs, whether you require white box analysis with source code review, grey box testing with limited credentials, or a pure black box assessment simulating an outside adversary. Hybrid testing can also be applied where appropriate to achieve complete coverage.

Findings are not delivered as raw lists of flaws. Instead, we demonstrate exploitability with evidence, highlight potential business consequences, and provide prioritised guidance to address weaknesses effectively. The result is a clearer understanding of your application’s true resilience and the confidence to maintain trust in the services you deliver.

Mobile applications bring your services directly to customers but also extend your attack surface into unmonitored environments. Unlike traditional web applications, mobile apps combine device-level storage, on-device logic, network communication, and backend API integrations. A weakness in any layer can compromise sensitive data or allow attackers to pivot into core systems.

Parabellum’s Mobile Application Penetration Testing addresses these challenges with a tailored approach across iOS and Android. Using white box, grey box, black box, or hybrid methodologies, our consultants examine every layer of the mobile ecosystem. We test for insecure storage of credentials and tokens, weak encryption, data leakage, and flaws in API calls that expose sensitive information.

We also validate user permission boundaries to ensure access controls cannot be bypassed. Where source code is available, we review it for insecure coding practices and logic flaws. Every finding is demonstrated with practical evidence and aligned to business impact, giving you clear, prioritised steps to harden your mobile security posture.

The result is confidence: mobile applications that not only function seamlessly but also defend the data and trust of your users.

Cloud services power modern business but they also introduce unique risks. Misconfigured permissions, overexposed storage, insecure APIs, and weak identity management can all create opportunities for attackers to gain access. With cloud platforms evolving rapidly, keeping pace with potential vulnerabilities is one of the most complex security challenges organisations face.

Parabellum’s Cloud Penetration Testing is designed to provide assurance that your environments are secure and resilient. Our consultants test AWS, Azure, Google Cloud, and hybrid deployments, applying white box, grey box, black box, or hybrid methodologies as needed. We validate identity and access management controls, assess service configurations, and attempt controlled exploitation of misconfigured resources to demonstrate potential impact.

We also evaluate how workloads, data storage, and APIs interact, identifying risks that could allow lateral movement or data leakage. Findings are supported by evidence and prioritised to highlight both compliance obligations and business risk.

The result is actionable clarity: a hardened cloud environment that delivers on its promise of agility and scale without compromising on security.

Operational Technology and Industrial Control Systems underpin some of the world’s most critical services, from energy generation and transport to manufacturing and water supply. A successful cyber attack against these environments can cause not only data loss but also operational disruption, financial impact, and risks to safety.

Parabellum’s OT, SCADA, and ICS Penetration Testing is designed to provide assurance without disrupting operations. Our consultants apply controlled, intelligence-led testing that mimics the tactics of real adversaries targeting industrial systems. We assess network segmentation, system configurations, authentication controls, and protocol security to uncover exploitable weaknesses.

Where appropriate, we also test vendor-specific implementations and validate whether monitoring and incident response processes can detect unusual activity in OT environments. Every engagement is tailored to the sensitivity of the systems in scope, ensuring that security is improved without introducing downtime or safety risk.

The result is confidence that your critical infrastructure is resilient against modern threats and meets the expectations of regulators, stakeholders, and the communities you serve.

Hardware and embedded devices are increasingly targeted by attackers seeking to bypass traditional security controls, extract sensitive data, or compromise systems at their most fundamental level. Weaknesses in chipsets, firmware, or physical interfaces can allow adversaries to reverse-engineer designs, clone intellectual property, or use a compromised device as a stepping stone into larger networks.

Parabellum’s Hardware Penetration Testing is designed to uncover and demonstrate these risks in a controlled environment. Our consultants apply advanced techniques including interface probing, firmware extraction, side-channel analysis, and controlled tampering to identify weaknesses. Where appropriate, we also test device-level cryptography and secure boot processes to validate resilience against manipulation.

Every engagement balances technical depth with practical outcomes. Findings are presented with evidence of exploitation and ranked by severity, along with prioritised remediation steps. The result is assurance that your hardware and embedded products are not only functional but secure, protecting both your customers and your intellectual property.

‍

Even the most advanced cyber defences can be undermined if attackers gain physical access to your physical environment. A successful intrusion can provide opportunities to steal data, tamper with equipment, or plant malicious devices that be utilised to bypass digital security altogether.

Parabellum’s Physical Penetration Testing simulates these real-world threats in a controlled and discreet manner. Our consultants attempt to breach physical barriers, exploit environmental weaknesses, and test staff awareness using techniques that mirror those of determined adversaries. This may include lock bypassing, tailgating, or the placement of rogue devices designed to compromise networks once inside.

Each engagement is carefully scoped to ensure safety and minimise disruption, while still providing an authentic measure of your facility’s resilience. Findings are supported with evidence such as photographs or logs, and are delivered with prioritised remediation guidance. The result is confidence that your physical environment is as secure as your digital one.
