CATO & VEILINTELLIGENCE & INVESTIGATIONSConfidential enquiryPENETRATION TESTING / VULNERABILITY ASSESSMENT / THREAT MODELLING
Penetration testing, source-code review, vulnerability scanning and threat modelling. Specialist technical assessment, connected with Cato & Veil’s investigative expertise.
Application / Infrastructure / Threat assessment
Commission a defined penetration test, vulnerability assessment or threat-modelling engagement. Where a concern extends beyond the system, our cyber investigations team connects technical findings with the people, relationships and information involved.
Technical cybersecurity services
Assessments are scoped to your systems, access requirements and objectives. Cato & Veil coordinates the relevant technical specialists and the reporting you need.
Web applications · APIs · Mobile
Test application security with an understanding of the code behind it. Source-code review and manual testing examine authentication, authorisation, data flows and business logic. Web, API and mobile assessments are scoped to the application and the access available.
Output Documented vulnerabilities, supporting technical evidence and remediation guidance for developers.
Discovery · Assessment · Prioritisation
Identify known weaknesses across the agreed systems and services. Scanning establishes broad coverage; assessment helps prioritise the findings. For ongoing programmes, define ownership, review cycles and remediation tracking around the organisation’s existing tools and resources.
Output Prioritised findings and a practical process for managing unresolved vulnerabilities.
Internal networks · External exposure · Cloud
Assess the security of agreed network and cloud environments. Examine exposed services, access arrangements and configurations, with the testing boundaries and access requirements established before work begins.
Output A technical account of identified weaknesses, affected systems and recommended changes.
Architecture · Data flows · Trust boundaries
Work with development and architecture teams to identify important assets, plausible attack paths and gaps in security controls. A structured model helps prioritise design decisions and further testing as the system changes.
Output A documented threat model, prioritised risks and recommendations for the team responsible for the system.
Dependencies · CI/CD · Integrations
Review the software components and delivery processes an application depends on. Assess dependency management, build pipelines, secrets handling and third-party integrations to identify where the supply chain introduces exposure.
Output Findings tied to the relevant dependencies, pipelines and integrations, with recommended improvements.
Agreed phishing simulations · Verification · Reporting
Use scoped phishing assessments to examine how staff and processes respond to deceptive communications. Connect the results with Cato & Veil’s understanding of impersonation, authority and trust to identify practical improvements to verification and escalation.
Output An assessment of the agreed exercise and recommendations for stronger processes and staff awareness.
From scope to remediation
Define applications, infrastructure, testing boundaries, access, timing and deliverables. Source-code-led testing requires access to the relevant code and environment.
Apply the agreed testing, scanning, code-review or threat-modelling methods. Record technical evidence, coverage and limitations.
Deliver prioritised findings and remediation guidance with a debrief. Follow-up testing and ongoing vulnerability management can be scoped around the work required.
Cyber investigations / The Cato & Veil approach
An access-control weakness, suspicious account activity or a deceptive payment instruction can raise questions about people, money and intent. A named investigation lead brings the relevant disciplines together from the outset.
Examine the available evidence of access, information loss and extortion alongside the organisation’s relationships and sensitive interests. Coordinate investigative enquiries with the technical response and the client’s advisers.
Investigate suspected information leakage, concealed interests and misuse of permissions. Compare records, witness accounts and relevant relationships, testing compromised access, error and deliberate involvement as competing explanations.
Connect deceptive communications, account activity and financial events. Examine how an instruction became credible, who acted on it and where the evidence leads.
Assess a suspicious sequence, supplier dependency or concern about sensitive information before the full picture is clear. Scope specialist security testing where a technical question needs examination.
Evidence / Context / Consequences
Technical findings direct interviews and background enquiries. Human accounts are checked against system records and communications. Financial analysis can establish how a disputed instruction connects to a transaction.
We also examine the narrative the evidence could support: what exposed information establishes, how selective extracts might distort it and where it conflicts with the organisation’s assurances. This helps leadership distinguish a misleading impression from a substantive problem that needs addressing.
Findings support the client’s legal and communications advisers and identify practical improvements to access, supplier oversight and decision-making.
What you receive
Deliverables are agreed around the engagement: a technical assessment for a defined security test, or an integrated evidence assessment where a wider investigation is required.
