What a penetration test gives your business
A penetration test puts your systems, networks and applications through the same techniques a real attacker would use. Our certified ethical hackers work through your environment methodically, and you get a precise account of what they reached, how they got there, and what it takes to close each route.
Penetration testing helps you:
-
Strengthen resilience across your environment, from external infrastructure through to internal systems.
-
Support compliance with the standards you report against, including ISO 27001 and PCI DSS.
-
Direct your remediation effort at the weaknesses that give an attacker the most ground.
-
Show customers, insurers and stakeholders that your security is tested independently.
Whether you're preparing for an audit, launching a new product or strengthening your defences, you get findings you can act on and remediation guidance shaped with your team around what you can realistically deliver.
Benefits of Penetration Testing
-
Realistic attack simulation: Testers use the techniques and tooling a real attacker would, against your live environment.
-
Reporting two audiences can use: Findings written for the engineers doing the work, and for the executives approving the time.
-
Scope set with you: Test parameters shaped around your systems, your risk areas and your delivery timelines.
-
Retesting when fixes land: Verify each remediation and confirm the fix held.
-
Scenario-based testing: Engagements built around the threats relevant to your sector and your technology.
-
Guidance after the report: A walkthrough of what was found and practical next steps for your security roadmap.
CREST accreditation is independently assessed rather than self-declared, covering technical capability, ethical conduct and quality of delivery. Your engagement follows the methodology and standards it certifies.
What a penetration test can cover in your environment
A penetration test can cover as much or as little of your environment as your priorities call for. We agree on the scope with you, and the findings feed into your longer-term security planning alongside your immediate fix list.

Different penetration tests for different scenarios
Each type of test answers a different question. Here's what each one examines and what you take away.
Infrastructure
Testing runs from outside and inside your network perimeter, covering exposed services, patching, configuration and internal movement. You see what an external attacker could reach, how far someone with internal access could travel, and what each route would mean for your operations.
Wi-fi
Testing examines encryption, authentication and access point configuration across your wireless networks, including the separation between guest and corporate access. You learn whether someone within range of your building could reach systems meant to stay internal.
Active Directory
Active Directory and Entra ID hold the keys to most networks. Testing covers privilege paths, group policy, delegation and credential exposure, showing how an attacker starting with one standard account could escalate toward domain administrator.
Web Application
Testing covers authentication, session handling, access controls, injection flaws and business logic across your web applications. You get reproducible evidence for each issue and the specific change that resolves it.
Web API
APIs are tested for broken authorization, excessive data exposure, rate limiting and input validation, including undocumented endpoints. Findings show what an authenticated user could reach beyond their own permissions.
Mobile Application
Mobile Application Penetration Testing covers your iOS and Android apps, including local data storage, certificate handling, API communication and code protections. You learn what could be extracted from a device in someone else's hands.
Segementation
Segmentation Penetration Testing checks whether your network segments hold up, examining access controls, firewall rules and traffic flow between zones. This is commonly required where PCI DSS calls for evidence that cardholder data environments are isolated.
IoT
Connected devices are tested across firmware, communication protocols, authentication and network exposure. You learn which devices could serve as a route into your wider network.
Cloud
Cloud Penetration Testing examines identity and access configuration, storage permissions, network controls and workload hardening across AWS, Azure and GCP. Findings separate what sits with your cloud provider from what belongs to your team.
Awareness Courses
Training sessions show your teams the techniques used in real phishing and social engineering attempts and how to recognize and report them. This is often scheduled after a social engineering test, ensuring the material reflects what happened in your own environment.

Pen Testing FAQs
What is penetration testing?
Penetration testing (or pen testing) is a simulated cyber attack against your systems, applications, or infrastructure. It finds weaknesses that attackers could use, along with offering ideas for improving your security.
Why do organizations need penetration testing?
Pen testing helps uncover hidden risks before real attackers do. It improves security posture, supports compliance, tests the effectiveness of existing controls, and gives clear, actionable recommendations for remediation.
What types of penetration tests does Integrity360 offer?
Integrity360 provides a wide range of penetration tests, including:
- External and internal infrastructure testing
- Web and mobile application testing
- Wireless and network segmentation testing
- IoT and OT (operational technology) testing
- Social engineering and phishing simulation
- Cloud security penetration testing (e.g. AWS, Azure)
What’s the difference between penetration testing and vulnerability scanning?
Automated vulnerability scanning identifies known issues. Penetration testing goes further, using manual methods to find weaknesses, assess their impact, and give insights. This helps show how an attacker might break into your system.
How often should penetration testing be carried out?
Best practice is to conduct pen testing regularly, or after significant changes to infrastructure, applications, or networks. Some industries may require more frequent testing to meet regulatory or contractual obligations. To determine the right frequency for your organization, connect with one of our pen testing experts.
Does penetration testing support compliance?
Penetration testing supports compliance across a range of frameworks and regulatory requirements, including ISO 27001, PCI DSS, NIST CSF, SOC 2, and PIPEDA. Integrity360 ensures testing aligns with each organization's specific audit and certification needs.
What deliverables are provided after a penetration test?
While deliverables vary based on your specific requirements, clients typically receive a detailed report including:
- Description of each vulnerability found
- Business risk ratings
- Proof-of-concept exploitation
- Technical and business impact
- Remediation advice
What makes Integrity360’s penetration testing different?
Integrity360’s testing is CREST-certified and delivered by experienced professionals. We blend technical skill with business knowledge. This makes your reports clear, useful, and in line with your security goals, not just technical lists.
