Penetration Testing &
Offensive Security
Practical security testing for applications, networks, cloud and identity. RTCS tests web applications, APIs, external and internal networks, Active Directory, Microsoft 365, Entra ID, cloud environments, mobile applications and wireless networks. We identify exploitable weaknesses, assess business impact and provide clear remediation advice your team can act on.

Find the weaknesses before attackers do.
Penetration testing is a controlled assessment that simulates how an attacker may attempt to compromise a system, application, network or cloud environment. The purpose is to understand what can be exploited, what access could be gained, what data may be exposed and what should be fixed first.
A penetration test can identify weak authentication, broken access controls, insecure APIs, exposed services, cloud misconfigurations, Active Directory attack paths, excessive privileges and sensitive data exposure.
Automated tools miss the things attackers actually use.
Security issues are introduced through new applications, cloud deployments, infrastructure changes, third-party integrations and identity changes. Automated scanners find some known vulnerabilities, but they miss business logic flaws, authorisation issues, privilege escalation paths and chained attack scenarios.
A penetration test answers the questions that matter
Can an attacker access sensitive data?
Can users access functions or records they shouldn't?
Are APIs enforcing authentication and authorisation correctly?
Are internet-facing systems exposed to attack?
Can a standard internal user escalate privileges?
Are Microsoft 365, Entra ID and cloud controls secure?
Can weaknesses be chained together to increase impact?
Testing across the surfaces that actually get attacked.
Web Application Testing
Authentication, session management, access control, injection, XSS, file uploads, SSRF, business logic flaws, password reset weaknesses, MFA bypass and sensitive data exposure.
API Penetration Testing
REST and GraphQL APIs - authentication, authorisation, BOLA, token handling, input validation, excessive data exposure, mass assignment, rate limiting and business logic.
External Network Testing
Internet-facing infrastructure - VPNs, remote access, firewalls, web servers, mail gateways, exposed ports, public services and management interfaces.
Internal Network Testing
What happens if an attacker, insider or compromised device is on the corporate network - host discovery, segmentation, privilege escalation, lateral movement and misconfiguration.
Active Directory Testing
Practical attack paths across users, groups, permissions, trusts, service accounts and GPOs - Kerberoasting, AS-REP roasting, delegation, local admin and attack-path mapping to crown jewels.
Entra ID & Microsoft 365
MFA, Conditional Access, privileged roles, PIM, legacy auth, enterprise apps and consent, SharePoint, Teams, guest access, external sharing, mailbox controls and audit logging.
Cloud Penetration Testing
Azure, AWS and Google Cloud - identity and access, public exposure, storage access, security groups, keys and secrets, privilege escalation, serverless, containers, logging and monitoring.
Mobile Application Testing
Android and iOS - insecure local storage, weak authentication handling, insecure API communication, sensitive data exposure, certificate validation and backend API weaknesses.
Wireless Security Testing
Corporate and guest wireless - encryption review, authentication controls, guest isolation, segmentation, rogue access point checks and signal exposure observations.
Tailored to scope. Broad in coverage.

How It Compares
Vulnerability Scanning
Checks known assets for known weaknesses. Provides breadth. Good as a starting point - never a deliverable on its own.
Penetration Testing
Validates exploitability, tests access controls, identifies business logic flaws and assesses how weaknesses chain together. Provides depth and practical validation.
When organisations engage RTCS for testing.
Scope to Retest
A practical, staged engagement that finds exploitable weaknesses, validates real-world impact, and gives your team a clear path to remediation.
Confirm systems, applications, accounts, testing windows, exclusions and rules of engagement.
Identify exposed services, functionality, user roles, APIs, permissions, technologies and possible attack paths.
Perform manual security testing using attacker-focused techniques, supported by controlled tools where appropriate.
Confirm whether findings are exploitable, remove false positives and assess likely business impact.
Provide a clear report with evidence, severity ratings, affected assets, business impact and remediation guidance.
Where included, retest remediated findings and confirm whether the issues have been resolved.
Who this service is for.
- Run public web applications or APIs
- Handle customer, employee, financial or sensitive data
- Need independent security assurance
- Need to test cloud, network or identity controls
- Need to assess Active Directory security
- Need to review Microsoft 365 or Entra ID security
- Want clear evidence of risk and remediation actions
Penetration testing gives your organisation a clear view of exploitable weaknesses and the practical steps needed to reduce risk - across applications, APIs, networks, Active Directory, Microsoft 365, Entra ID, cloud, mobile and wireless.
Common Questions
What is penetration testing?
Penetration testing is a controlled security assessment that identifies exploitable weaknesses in applications, networks, cloud environments and identity platforms.
Do you provide a report?
Yes. RTCS provides a clear report with findings, evidence, risk ratings, affected assets and remediation guidance.
Can you retest after fixes are applied?
Yes. Retesting can be included to confirm whether identified issues have been remediated.
Do you test APIs?
Yes. RTCS tests REST and GraphQL APIs, including authentication, authorisation, input validation, object level access controls, rate limiting and business logic.
Do you test Active Directory?
Yes. RTCS tests Active Directory for privilege escalation paths, weak permissions, credential exposure, lateral movement opportunities and misconfigurations.
Do you test Microsoft 365 and Entra ID?
Yes. RTCS can assess Microsoft 365 and Entra ID controls, including MFA, Conditional Access, privileged roles, app consent, guest access, external sharing and security logging.
Do you test cloud environments?
Yes. RTCS can assess Azure, AWS and Google Cloud environments where included in scope.
Available across Australia.
