SERVICES

What we do

Identifying weaknesses, testing defences, and delivering actionable
insights to keep your organisation secure.

PENETRATION TESTING

Identify weaknesses before attackers do.

WHY IT MATTERS

Simulated attacks uncover hidden vulnerabilities across your systems, giving you the insight to prevent breaches and strengthen your defences proactively.

WHAT WE OFFER

Web / API applications
Thick client applications
Internal infrastructure
IoT / Embedded devices
Mobile apps
Cloud infrastructure

KEY OUTCOMES

Comprehensive vulnerability report
Prioritised risk recommendations
Executive summary for management
Improved security posture and reduced exposure

METHODOLOGY

We combine automated scanning with expert-led manual testing tailored to your environment. Every penetration test is structured to deliver clear findings, practical remediation guidance, and measurable security improvement.

HARDWARE & IoT HACKING

Uncover exploitable weaknesses across your infrastructure.

WHY IT MATTERS

Embedded systems and connected hardware often operate outside traditional security monitoring. Weak firmware, insecure communication protocols, and misconfigured interfaces can provide attackers with direct entry into your infrastructure.

WHAT WE OFFER

Firmware analysis and extraction
Hardware interface testing (UART, JTAG, SPI)
Wireless protocol security testing
Embedded device exploitation
Secure boot and firmware validation

KEY OUTCOMES

Clear visibility of device-level vulnerabilities
Identification of insecure firmware and communication flows
Prioritised remediation roadmap
Reduced risk across your physical and IoT attack surface

METHODOLOGY

We combine hands-on hardware analysis with protocol testing and exploitation techniques to evaluate your devices in real-world conditions. Each assessment is tailored to your hardware architecture and deployment model.

RED TEAM EXERCISES

Stress-test your organisation's detection, response, and resilience.

WHY IT MATTERS

Traditional testing finds vulnerabilities. Red teaming tests whether they can be exploited in realistic attack scenarios. It evaluates not just technical controls, but detection, response, and decision-making under pressure.

WHAT WE OFFER

Targeted adversary simulations
Phishing and social engineering campaigns
Initial access and lateral movement testing
Privilege escalation and persistence validation
Full attack chain emulation

KEY OUTCOMES

Realistic attack scenario findings
Assessment of detection and response readiness
Executive-level risk insight
Clear recommendations to strengthen resilience

METHODOLOGY

We operate as a simulated adversary, following structured attack paths aligned to real-world threat actors. Engagements are carefully scoped, controlled, and measured to provide actionable intelligence without operational disruption.

PURPLE TEAM EXERCISES

Collaborative offensive + defensive testing that sharpens your SOC.

WHY IT MATTERS

Security maturity improves fastest when offensive and defensive teams work together. Purple teaming bridges the gap between attack and detection, accelerating improvement across your SOC and response workflows.

WHAT WE OFFER

Guided attack simulations
Detection rule validation
Log and alert review
SOC process evaluation
Real-time defensive coaching

KEY OUTCOMES

Enhanced detection capability
Reduced response gaps
Optimised monitoring rules
Improved collaboration between teams

METHODOLOGY

We conduct controlled adversary simulations while working directly with your defenders. By testing and tuning controls in real time, we deliver measurable improvements in detection coverage and response efficiency.

APPLICATION SECURITY

End-to-end security testing in your applications before deployment.

WHY IT MATTERS

Applications remain a primary target for attackers. Vulnerabilities introduced during development can expose sensitive data, disrupt services, and create regulatory risk if left unchecked.

WHAT WE OFFER

Source code review
Vulnerability assessments
DevSecOps integration support
Secure architecture review
CI/CD security validation

KEY OUTCOMES

Detailed vulnerability assessments
Actionable remediation guidance for developers
Secure development lifecycle alignment
Reduced application-layer risk

METHODOLOGY

We combine automated tooling with expert manual review to identify logic flaws, insecure patterns, and architectural weaknesses. Each assessment is aligned to your technology stack and development workflow.

SECURE CODE REVIEW

Manual and automated audits that reveal insecure code paths.

WHY IT MATTERS

Automated scanners often miss business logic flaws and subtle implementation weaknesses. A structured code review provides deeper visibility into how your software behaves under real-world conditions.

WHAT WE OFFER

Manual code analysis
Security-focused pull request review
Authentication and authorisation validation
Input handling and data flow analysis
Secure coding best practice guidance

KEY OUTCOMES

Precise identification of high-risk code paths
Clear remediation recommendations
Improved developer security awareness
Stronger alignment with industry standards

METHODOLOGY

Our reviewers analyse your codebase with an attacker’s mindset, focusing on logic, trust boundaries, and exploitability. Findings are delivered in a format developers can immediately act on, reducing friction and accelerating remediation.
