What Is a Penetration Test?

A penetration test, or “pen test,” is a controlled, ethical hacking exercise designed to identify and exploit vulnerabilities in your systems before malicious actors can. It simulates real-world cyber attacks to assess the resilience of your infrastructure, applications, and defences. At Heretek, our penetration testing services span across critical domains—including internal and external infrastructure, web applications, APIs, AI-powered applications, and cloud environments—to give you a clear, practical view of your organisation’s security posture.

Who needs penetration testing?

If you have something worth protecting, it’s worth testing.

Penetration testing isn’t just for big enterprises or ticking compliance boxes. It’s for anyone building something worth protecting, from fast-moving startups to growing teams managing complex systems. Whether you’re launching a product, preparing for an audit, scaling infrastructure or just want to know where you really stand, a tailored pentest gives you clarity.

We work with organisations of all shapes and sizes such as product teams, IT departments, MSPs and even high-risk individuals to help them understand and reduce their exposure before attackers get the chance.


What Makes Our Testing Stand Apart

Our goal is to go beyond simply finding weaknesses. Our expert testers, trained in both offensive (red team) and defensive (blue team) tactics, leverage a purple team philosophy to deliver realistic, high-impact assessments. We don’t just find issues; we help you understand their business risk and how to remediate them effectively.

By mimicking the tools, techniques and mindset of real attackers, our expert testers provide actionable insights to strengthen your defences, reduce risk and meet compliance obligations. Whether you’re securing a SaaS platform, preparing for a compliance audit, or validating the security of your AI and cloud deployments, Heretek delivers thorough, tailored testing aligned with your goals.

Our Penetration Testing Services

Security isn’t one-size-fits-all and neither are our penetration tests.
We design each engagement around your specific infrastructure, industry, compliance needs and threat landscape.

 

External Infrastructure Penetration Testing

Protect your internet-facing systems like firewalls, VPNs and public servers by identifying vulnerabilities hackers could exploit in your perimeter defences.

Internal Infrastructure Penetration Testing

Simulate insider threats to uncover internal risks and lateral movement vulnerabilities before malicious users or compromised devices can exploit them.

Web Application Penetration Testing

Secure your websites and web apps by testing for vulnerabilities like SQL injection, XSS, and authentication flaws that could lead to data breaches.

Cloud Platform Penetration Testing
(AWS, Azure, Microsoft 365)

Prevent data leaks and account breaches by assessing cloud configurations, identity controls, and exposed services for security gaps and misconfigurations.

Mobile Application Penetration Testing
(iOS & Android)

Ensure your iOS and Android apps protect user data by evaluating them for insecure storage, weak authentication and API vulnerabilities.

API Penetration Testing
(REST, GraphQL, SOAP)

Safeguard backend systems and sensitive data by testing exposed APIs for access control issues, injection flaws and data leakage vulnerabilities.

Active Directory Security Assessment

Audit your AD environment for misconfigurations, privilege escalation paths, and identity security flaws to strengthen your access controls.

Wireless Network Penetration Testing
(Wi-Fi)

Secure your wireless infrastructure by identifying weak encryption, rogue access points and signal leaks that could allow unauthorized access.

AI Application Security Testing
(LLMs, ML APIs, Models)

Protect your AI and ML systems by analysing them for prompt injection, data leakage and model abuse risks that could lead to misuse or compromise.

WHAT TO EXPECT

Scoping the assessment

We take the time to understand what systems, applications and environments that you really want us to focus on. This gives our consultants a good estimate of the effort and time required as well as any technical requirements which need to be arranged before the assessment can begin.

Automated testing and Manual analysis

We carry out a range of automated scans depending on the types of target and environment to gather as much data as possible. Then one of our qualified and experienced consultants will validate the findings to ensure there are no false-positives.

exploitation and impact assessment

During the exploitation and impact assessment phase of a penetration test, our team actively attempts to exploit identified vulnerabilities to understand how an attacker could gain access, escalate privileges, or move laterally within your environment. This phase goes beyond theoretical risks, demonstrating the real-world consequences of each weakness—whether it’s data exfiltration, system compromise, or service disruption. By safely simulating these scenarios, we provide clear insight into the potential business impact and help prioritise remediation based on risk.

Prioritised reporting and remediation guidance

After gathering all the data on the systems, applications or environments and identifying potential security issues these are collated into individual findings on our reporting portal for you to view immediately. Each one comes with expert guidance on remediation and the portal can help you track your progress as fixes are applied.
