Penetration Testing

A Penetration Test goes further and deeper than a Vulnerability Assessment. A human tester will safely exploit security weaknesses in order to gain further access to your critical systems, therefore mimicking the actions of a potential threat actor.

Risk Prioritisation

Identify your high risk vulnerabilities so you can prioritise your remediation activities.

Security Culture

Demonstrate mature security culture within the business.

Meet Standards

Meet regulatory and compliance standards, such as PCI DSS and ISO27001.

Data Security

Show your clients that securing their data is important.

Infrastructure

We test the backbone of your business- from firewalls to domain controllers, to see how well your network holds up under pressure. Because strong foundations matter. We test a variety of connected devices, including servers, laptops, printers, storage drives, network gear, and even your web applications. We look at how these systems work together, who can access them, and how data flows between them.

External Infrastructure

This is what your systems look like to the outside world. We scan, probe and attack just like a real threat actor would- no VPN required.

Wireless Assessment

Your Wi-Fi shouldn’t be a backdoor into your network. We test your wireless setup for weak encryption, rogue access points and misconfigured gear- because attackers love to sit in the car park too.

Active Directory Assessment

AD is the crown jewel for attackers. We dig into your domain looking for misconfigurations, excessive privileges and common escalation paths- before ransomware operators do.

Build Review

We dive into your server, workstation, and image configurations to check for weak defaults, misconfigurations and other nasties hiding in plain sight. Clean builds = safer systems.

Internal Infrastructure

We evaluate your hosts from inside your network, to evaluate your environments security posture. Can we access critical data? Let’s find out- before someone else does.​

Segmentation Testing

Segmentation only works if it actually segregates. We test whether your network zones are truly isolated- or if one small foothold gives us the keys to the kingdom.

Blackout Testing

Got locked-down desktops or kiosks? Let’s see if we can break out of them. We test whether users (or attackers) can escape restricted environments and pivot into your internal systems.

Firewall Configuration Review

Keep your network secure and compliant with our Firewall Configuration Review service. We regularly assess your firewall settings to detect misconfigurations, outdated appliance software and vulnerabilities that attackers could exploit.

Applications

Your apps are the front door to your business. We test them like a real attacker would- looking for logic flaws, auth bypasses, injection bugs, and everything in between.

Mobile Applications

We reverse engineer, tamper, and poke around your iOS and Android apps to see how secure they really are on device.

Desktop Applications

We pull apart your desktop apps, installers, binaries, and local storage to uncover weak protections, poor cryptography, sensitive information and opportunities for tampering or privilege escalation.

Web Applications

From login pages to payment services, we dig into your web stack to uncover the stuff automated scanners miss. OWASP Top 10? That’s just our warm-up.

API

API's are powerful and often overlooked. We enumerate, fuzz and manipulate requests to identify, broken authentication mechanisms, bad logic, data exposure and anything that could turn a useful feature into a security risk.

Cloud

You’ve moved to the cloud- great. But are your security controls following? We test your cloud posture the same way attackers do, across services, roles, and misconfigurations.

Cloud Configuration Reviews

(AWS, Azure, GCP, Oracle…)

We assess your cloud environments, AWS, Azure, GCP, Oracle- no matter the platform, we're here to help. We perform in-depth analysis of your configuration and security posture against best practices to evaluate your access controls, databases, networks, storage areas, message queues and audit controls. We leave no service unchecked.

Containerisation

Kubernetes. Docker. You name it- we look inside your container stacks to find weak configurations, misconfigured control planes, vulnerable images and risky orchestration setups. 

Penetration Testing Extras

You’ve moved to the cloud- great. But are your security controls following?

Vulnerability Management

Finding vulnerabilities is easy. Managing them? That’s the challenge. We help you prioritise, track, and fix what matters- without drowning in noise.

Frameworks & Methodologies

We follow a number of industry and framework standards such as CREST, NIST, OWASP, PCI-DSS, CE, CE+ and more. But we also adapt to your environment and requirements providing real-world testing, not just a checkbox exercise. 

PortalPortal

Our very own secure, client portal gives you a clear view of everything; findings, reports, risk scores, remediation progress- all in one place. No spreadsheets, no mess.

Sample Reports

Want to see what you’re getting before you commit? Our sample reports show exactly how we communicate findings- clear, detailed, and tailored for both tech teams and execs.
