Expert Security Testing Services

Get peace of mind that your applications, APIs, networks and AI systems are secure. We identify the weaknesses that matter, prove they are exploitable, and give your team the evidence to fix them.

Our offensive security services — penetration testing, AI and agent security reviews, cloud and network assessments, and continuous validation — simulate the tactics, techniques and procedures used by real attackers.

Our specialists work to established methodologies, with human judgement on every finding. You get actionable intelligence, not another scanner report.

  • Evidence-led findings, prioritised by real business risk.
  • Human-validated results, with reproduction steps your engineers can use.
  • Guidance from first finding to verified closure.
Release fasterSecurity that matches deployment speed.
Cut breach riskReal attack paths found before criminals do.

Application & AI Security

Application and AI security covers the software your business runs on — web, API, mobile and AI — with the depth of a human attacker and the coverage of automation.

Web

Web Application Testing

Web application testing covers authenticated flows, business logic, access control and injection classes across the application's entry points and roles.

Testing follows the data across the application, with reproducible evidence on every finding.

  • OWASP Top 10 and WSTG coverage
  • Business-logic and access-control flaws
  • Authenticated flows incl. SSO and MFA
API

API Testing

REST, GraphQL and SOAP APIs are tested for authentication, authorization and rate limits.

Coverage includes schema exposure, object-level authorization and the auth flows behind the API.

  • BOLA/IDOR and function-level authorization
  • JWT, OAuth and rate-limit abuse
  • GraphQL introspection and schema abuse
Mobile

Mobile Application Testing

iOS and Android applications are assessed for insecure storage, transport and platform permissions.

The app and its backend are reviewed together, because the weakest path is often between them.

  • Insecure data storage and transport
  • Authentication and session handling
  • Platform permission and IPC review
Code

Static Code Review

Source code review targets the classes of weakness that scanners miss, focused on reachable, exploitable paths.

The review concentrates on real data flows and reachable code, not a list of theoretical issues.

  • Injection, deserialization and crypto misuse
  • Secrets and dangerous configuration
  • Prioritised findings with fix guidance
AI

AI & LLM Testing

LLM applications and agent workflows are assessed against the OWASP LLM Top 10.

The application, its model and the tools it can reach are tested as one system.

  • Prompt injection, tool abuse and RAG poisoning
  • Data exposure and excessive permissions
  • RAG and retrieval-boundary testing
Threat

Threat Modelling

Threat modelling maps the system, its trust boundaries and attacker-relevant assumptions before testing begins.

The output is a prioritised test plan, not a diagram that sits on a shelf.

  • Architecture and data-flow review
  • Prioritised abuse cases and test plan
  • Design review and attack-path mapping

Infrastructure, Assurance & Forensics

Infrastructure, assurance and forensics cover the layers beneath the application — the network, the cloud, the people and the evidence — so the whole estate is covered.

Internal

Internal Network

Internal network testing simulates an attacker inside the perimeter, covering segmentation and privilege paths.

Testing follows the credentials, trusts and sessions that allow an attacker to move.

  • Lateral movement and privilege escalation
  • Active Directory and identity paths
  • Segmentation and control gaps
External

External Network

External network testing covers internet-facing assets, services and remote access for exploitable exposure.

The focus is on the assets an attacker can reach without credentials.

  • Open services and exposed panels
  • VPN, remote access and patch gaps
  • Exposed admin interfaces and weak TLS
Cloud

Cloud & Identity

Cloud and identity reviews examine configuration, identity boundaries and exposure paths across the estate.

The review focuses on the boundaries that separate data from the internet.

  • IAM, privilege and trust boundaries
  • Public exposure and misconfiguration
  • Logging, monitoring and guardrails
Red Team

Red Teaming

Red teaming is full-scope adversary simulation against people, process and technology.

Objectives and rules of engagement are agreed up front, then the whole organisation is tested.

  • Multi-stage attack chains
  • Detection and response review
  • Social engineering and physical scope
Compliance

PCI DSS

PCI DSS testing assesses cardholder-data environments against PCI DSS requirements and produces audit-ready evidence.

The CDE is mapped, segmentation is validated and evidence is packaged for the assessor.

  • External and internal PCI scope
  • Segmentation and evidence pack
  • Scope validation and segmentation testing
Forensics

Reverse Engineering & Forensics

Reverse engineering and forensics analyse binaries, firmware and artefacts to understand behaviour, extract evidence and assess exposure.

Static and dynamic analysis are combined to show what the artefact actually does.

  • Binary and firmware analysis
  • Credential extraction and incident artefacts
  • Firmware and embedded device review

Scope

Objectives, assets and rules of engagement.

02

Discover

Recon, mapping and attack-surface review.

03

Validate

Safe exploitation, chaining and emerging threats.

04

Prioritize

05

Retest

Guidance, then validate fixes to closure.

Typical deliverables
  • Executive summary with business context and risk posture
  • Technical findings with evidence and reproduction steps
  • Risk-ranked remediation guidance
