Penetration Testing Services
Simulate Real Attacks. Expose Real Risk. Fix It Before It’s Exploited.
Australian organisations are now prime targets for ransomware, credential theft, and business email compromise.
Attackers do not care about your size.
They care about your exposure.
At Sentry Cyber, we deliver controlled, ethical penetration testing that simulates real world attack techniques to identify exploitable weaknesses across your environment.
This is not a scan.
This is controlled adversarial simulation.
Why Penetration Testing Matters
Most organisations believe their controls are working.
Until they are tested, that belief is an assumption.
Penetration testing validates:
- Whether external attackers can access your systems
• Whether internal compromise leads to full takeover
• Whether privileged accounts are exploitable
• Whether phishing leads to credential compromise
• Whether ransomware paths exist
It answers one critical question:
If we were attacked tomorrow, what would actually happen?
Our Penetration Testing Approach
We focus on real attack paths and business impact.
1. Scoping & Threat Profiling
We identify critical systems, high value accounts, and realistic attacker scenarios.
2. Controlled Ethical Exploitation
We simulate the techniques used by modern threat actors in a controlled and authorised manner.
3. Risk Based Reporting
Executive summary for leadership.
Technical breakdown for IT teams.
Clear business impact explanation.
4. Remediation Guidance & Optional Retesting
We do not just report findings.
We help you fix them.
Our Penetration Testing Capabilities
We provide comprehensive testing across the environments most targeted in medium sized organisations.
Web Application Penetration Testing
Aligned to modern application security testing standards.
We evaluate:
- Authentication controls
• Authorisation flaws
• Injection vulnerabilities
• Session management weaknesses
• API exposure
Designed to protect customer data and online services.
External Penetration Testing
Tests internet facing assets such as:
- Firewalls
• VPN gateways
• Remote access portals
• Public cloud services
• Exposed web services
This identifies vulnerabilities that external attackers could exploit without prior access.
Internal Network Penetration Testing
Simulates what happens if an attacker gains a foothold inside your organisation.
We assess:
- Lateral movement capability
• Privilege escalation risks
• Weak admin controls
• Network segmentation gaps
• Domain takeover scenarios
Critical for ransomware resilience.
Google Workspace Penetration Testing
Many medium organisations operate almost entirely in Google Workspace.
We test:
- Admin privilege governance
• OAuth and third party app abuse
• Drive data exposure
• Session and login protections
• Domain wide delegation risks
• Impersonation scenarios
This is especially relevant for organisations with distributed teams and cloud first operations.
Mobile Application Penetration Testing
Mobile applications are increasingly targeted for credential theft, API abuse, and data extraction.
We assess:
- Authentication and session management
• Insecure data storage
• API communication security
• Reverse engineering risks
• Business logic flaws
Designed to identify weaknesses before attackers exploit your customers or staff through mobile channels.
Wireless Penetration Testing
Wireless networks are often overlooked and misconfigured.
We test:
- WiFi encryption strength
• Rogue access points
• Guest network segmentation
• Authentication weaknesses
• Signal leakage beyond premises
This identifies whether attackers can gain access from the car park, neighbouring offices, or public areas.
Hardware, Embedded Systems & IoT Penetration Testing
Connected devices introduce unique attack surfaces.
We assess:
- Firmware vulnerabilities
• Default credentials
• Network exposure
• Device to cloud communication
• Update and patching mechanisms
Critical for organisations using smart devices, access control systems, CCTV, or industrial equipment.
Artificial Intelligence & AI System Penetration Testing
AI driven systems introduce new risk vectors.
We test:
- Prompt injection vulnerabilities
• Data poisoning risks
• Model manipulation
• Access control weaknesses
• Sensitive data exposure through AI outputs
Essential for organisations deploying AI tools internally or customer facing AI platforms.
IT Helpdesk Security Testing
Your security is only as strong as your IT provider.
We assess the robustness of your managed service provider or outsourced IT partner, including:
- Privileged access management
• Remote access security
• Backup integrity
• Monitoring controls
• Incident response readiness
This ensures your external IT support does not become your biggest vulnerability.
Phishing & Social Engineering Testing
Technology is only one layer of defence.
We simulate:
- Targeted spear phishing campaigns
• Executive impersonation attempts
• Credential harvesting scenarios
• AI generated phishing lures
This measures real human risk exposure across your organisation.

Frequently Asked Questions
What is penetration testing?
Penetration testing is a controlled and authorised simulation of a cyber attack designed to identify exploitable weaknesses in your systems, applications, cloud platforms, or networks before real attackers do.
How much does penetration testing cost in Australia?
Penetration testing costs vary depending on scope, complexity, and environment size. A defined project based engagement typically has a fixed price, while ongoing subscription models spread the cost across 12 months for predictable budgeting. Pricing depends on the assets tested and depth required.
How long does a penetration test take?
Most penetration testing engagements take between one and four weeks, depending on scope. Larger or more complex environments may require additional time for testing and reporting.
How often should penetration testing be performed?
At minimum, penetration testing should be performed annually. It should also be conducted after major infrastructure changes, cloud migrations, application deployments, or security incidents.
What is the difference between vulnerability scanning and penetration testing?
Vulnerability scanning uses automated tools to identify potential weaknesses. Penetration testing goes further by validating exploitability through controlled attack simulation and demonstrating real world risk.
What is the difference between penetration testing and red team testing?
Penetration testing focuses on identifying and validating specific vulnerabilities within defined scope. Red team testing simulates a broader adversarial campaign designed to test detection and response capabilities across the organisation.
Does penetration testing disrupt business operations?
Professional penetration testing is carefully coordinated to minimise disruption. Testing is conducted in controlled windows and agreed scope boundaries to avoid operational impact.
Do you provide a remediation plan after testing?
Yes. Every engagement includes clear remediation guidance, prioritised by business impact. We can also provide retesting to validate fixes once remediation is complete.
Can penetration testing help prevent ransomware?
Penetration testing identifies common ransomware attack paths such as privilege escalation, weak segmentation, exposed services, and credential compromise. While no control can guarantee prevention, testing significantly reduces exploitable exposure.
Is penetration testing required for compliance?
Many compliance frameworks and industry standards recommend or require independent security testing. While requirements vary by industry, penetration testing is commonly used to demonstrate due diligence and risk management.
Do you test cloud platforms like Google Workspace?
Yes. We perform controlled testing of cloud environments, including identity controls, privilege governance, third party integrations, and data exposure risks.
What happens after the penetration test is completed?
You receive a structured executive summary and detailed technical report. For subscription clients, findings are tracked and reviewed over time to ensure continuous improvement.
