Infrastructure Penetration Testing
View methodology and coverage
Network, Infrastructure & Cloud
Whether you are a digital asset provider with some Azure cloud infrastructure, or an international telecoms organisation with hundreds of thousands of public IPs, we can thoroughly assess your network infrastructure (on-prem or cloud) with expert level attack coverage.
We cover hybrid estates across AWS, Azure, and GCP, focusing on exposed services, identity pathways, segmentation gaps, and cloud control-plane misconfigurations that drive real-world risk.
On-Prem Infrastructure
Assess routing, segmentation, legacy services, and internal attack paths across critical systems.
Cloud Environments
Test cloud posture, identity controls, storage exposure, and control-plane security in AWS, Azure, and GCP.
Hybrid Attack Surface
Validate cross-environment pivots, VPN and SD-WAN boundaries, and shared identity trust.
Scope
Atlan Digital R&D works with you to develop a detailed scope of the penetration testing to be undertaken.
Recon
In the first phase Atlan Digital R&D will perform OSINT, analysing the routing mechanisms, and then all your systems will be scanned for all active TCP and UDP ports and we will establish the security rule-base.
Exploit
In the exploitation phase Atlan Digital R&D will iteratively identify and exploit vulnerable systems using public vulnerability information, and configuration & design errors. A scenario analysis over the entire network is conducted.
Report
In the final phase Atlan Digital R&D will perform comprehensive reporting of the issues identified. The risks will be rated according to numeric CVSS scores alongside an internal qualitative risk grading.

We work closely with developers to expedite understanding of the code and architecture, and provide knowledge transfer.
Information Gathering
Review of the application’s supporting documentation and development guidelines, identifying intended purpose, functionality and development approach.
Dynamic Analysis

Custom Software, Machine Learning & Tooling
With many of our consultants having contributed to the security community, or having been full time developers themselves, we can respond to requests to develop programmatic solutions where cyber security domain knowledge is essential.

Example Capability – SharpML:
SharpML employs C# to mine Active Directory file shares, while bundling a resource file. This resource file is a custom Machine Learning algorithm written in Python (compiled with Pyinstaller) whose logic uses Clustering and Classification to evaluate the likelihood of User / Password combinations and subsequently automatically test these against a Domain Controller to assist operators in identifying passwords littered on fileshares.
A version of this tool had been open sourced by the consultants when at Hunnic Cyber, but Version 2, wherein further developments have been made internally by Atlan Digital R&D, can be requested. The write up can be viewed here. Our research outline around building a Generative Adversarial Network for Malware Development can be viewed here.
Penetration Testing
We can develop solutions to complement our manual testing activities to enable a client to be tested 24/7, 365 days of the year.
Red Team & Malware Development
We can assist clients or other consultancies in developing tooling to enhance security testing activities.
Machine Learning & Automation
As part of our consulting efforts we can develop solutions to help automate security tasks, continuous security scanning tools, or apply machine learning to security problem solving.
