What we can test

Every engagement is scoped around your environment, objectives and risk priorities.

Identify vulnerabilities in websites and web applications, including authentication, access control, input validation and session handling issues.

Assess API endpoints, authentication flows and data exposure risks before they can be exploited.

Test internet-facing systems to identify weaknesses that could be discovered or targeted by attackers.

Assess internal infrastructure to understand how vulnerabilities could be used to move through your environment.

Review cloud-hosted systems and configurations for security weaknesses and exposure risks.

Validate fixes after remediation and receive practical guidance on reducing risk.

When a penetration test can help

Organisations usually come to us when they need assurance, evidence or a clearer view of security risk.

You may need a penetration test if you are:

  • Preparing for an audit, certification or customer security review
  • Launching a new website, application, API or platform
  • Responding to a supplier or third-party assurance requirement
  • Validating cloud, infrastructure or network security
  • Checking that previous remediation work has been effective
  • Looking for practical evidence to support cyber risk decisions

Why choose C3IA?

Experienced Security Consultants

Our testing is delivered by experienced cyber security consultants, including individuals who hold CHECK Team Leader and CHECK Team Member status.

Clear, practical reporting

You receive clear findings, risk ratings and remediation guidance that can be understood by both technical teams and decision-makers.

Scoped around real risk

We tailor each engagement around your systems, objectives and operational constraints rather than treating testing as a checkbox exercise.

The C3IA Process

We confirm what needs testing, your objectives, access requirements, timescales and any compliance or assurance requirements.

We agree testing windows, points of contact, rules of engagement and technical details before work begins.

Our consultants assess your systems using controlled, real-world attack techniques appropriate to the agreed scope.

Critical findings are communicated as they are discovered, allowing risks to be addressed without waiting for the final report.

You receive a clear report with prioritised findings, risk ratings, evidence and practical remediation guidance.

We can walk through the results with your team and retest fixes where required.

A good penetration test should help you understand what matters most.

C3IA provides clear reporting that explains the risk, likely impact and practical next steps. Critical findings can be communicated during the engagement where appropriate, helping your team act quickly on the issues that matter most.
