Offensive Security
We don't run scanners and call it a pentest. Our operators break into networks, applications, and infrastructure with the same techniques used by advanced threat actors.
Automated tools and compliance frameworks have made security testing more common, but they haven't made it more effective. Real attackers don't follow compliance checklists.
Internal and external network assessments that go beyond automated scanning. We chain vulnerabilities to demonstrate real business impact.
Deep manual testing of complex web applications, APIs, and microservices architectures. OWASP-aligned but never limited to a checklist.
Reverse engineering and dynamic analysis of iOS and Android applications, including backend API testing and local data storage review.
Full-scope adversary simulation with custom implants, social engineering, and physical access testing. We measure your detection and response, not just your perimeter.
Specialised testing for industrial control systems, SCADA environments, and critical infrastructure — conducted safely with production-aware methodologies.
Firmware extraction, hardware interface analysis, and RF protocol testing for connected devices across industrial and consumer verticals.
Configuration review and attack-path analysis across AWS, Azure, and GCP. We identify privilege escalation routes and lateral movement opportunities in your cloud estate.
Targeted phishing, vishing, and pretexting campaigns designed to test your human layer. We measure click rates, credential capture, and policy bypass.
Collaborative engagements where our offensive operators work alongside your SOC to improve detection rules, playbooks, and response times in real time.
Every engagement follows a structured methodology designed to produce actionable intelligence, not just a vulnerability list.
We work with you to define the engagement boundaries, perform threat modelling, and map the attack surface. Scope is always driven by business risk, not technical convenience.
Our operators conduct manual exploitation, chaining vulnerabilities to build realistic attack paths. No reliance on off-the-shelf scanners — every finding is human-validated.
We document the business impact of every attack chain: what data was accessed, what systems were reachable, how far lateral movement could have gone.
Findings are delivered with full evidence packs, CVSS scoring supplemented by business risk context, and actionable remediation guidance prioritised by real-world exploitability.
Critical findings are re-tested at no charge within 90 days of remediation to confirm the attack path has been closed — not just the vulnerability patched.
A financial services firm wanted an external network assessment. The scope included the DMZ and internal network after initial access.
We chained three individually low-severity findings — an exposed legacy service, a misconfigured internal DNS record, and a weak service account credential — to achieve domain administrator access within 48 hours. The client had previously passed their annual compliance scan.
A manufacturing company engaged us for a full-scope red team with no restrictions on attack vectors, including physical access.
A targeted phishing campaign against a facilities contractor yielded credentials to a VPN portal. Combined with physical access to an unlocked server room, we achieved persistent access to OT systems within four days. Detection time was eleven days after we notified the client.
An e-commerce platform had completed a recent internal security review and was seeking independent validation before a major product launch.
Manual testing of the checkout flow identified an authentication bypass in the order history API. An unauthenticated attacker could enumerate and access any customer's full order history and partial payment details. The internal review had not flagged the issue.
A utilities operator needed a security assessment of their SCADA environment managing water treatment facilities.
Network segmentation between IT and OT was insufficient. We identified an unauthenticated path from the corporate network to a SCADA historian, and from there to the control layer — including a command interface that could have been used to disrupt treatment operations remotely.
Every engagement starts with understanding your business context. We don't just find vulnerabilities — we demonstrate what an attacker can achieve and help you prioritise based on real risk.
BUC has been running offensive engagements since the early 2000s. Our operators have seen attacks evolve across every generation of enterprise technology — and our techniques evolve with them.
Every operator on our team holds current industry certifications. Certifications don't make a great pentester, but they are a baseline signal — our operators go well beyond them.
Our internal research lab continuously develops new offensive techniques against emerging attack surfaces. What we discover in the lab goes into production engagements — not just conference talks.
Remediation guidance is only valuable if it works. We re-test every critical finding at no charge within 90 days to confirm the attack path has been eliminated, not just the symptom addressed.
