Pen Testing for Web Apps, API & Mobile

Web App Penetration Testing for Web, API & Mobile Applications

CyberLab’s expert-led web application penetration testing helps you identify and eliminate vulnerabilities across your web apps, mobile applications, and APIs.

From SQL injection, cross-site scripting (XSS), and insecure endpoints to authentication flaws and data exposure, we uncover the risks before attackers do.

Fast, focused, and fully compliant, our penetration testing services ensure your web, mobile, and API platforms are secure, resilient, and ready for growth.

I’d recommend CyberLab not just for their expertise in the whole cyber security area, but for their personalised and professional approach.

Why Website & Application Security Testing?

Website and Application Security Testing identifies vulnerabilities in your digital platforms, such as code flaws or weak configurations, that can be exploited by cyber criminals. Regular testing helps prevent data breaches, secure user information, and maintain trust.

With cyber threats evolving constantly, it’s essential to stay ahead of potential risks by ensuring your websites and apps are fortified against attack.

When deadlines are tight and compliance can’t wait, CyberLab delivers. Our CREST-accredited testers can begin your penetration test in as little as 24 hours – without compromising on quality or detail.

Website & App Security Testing: The CyberLab Approach

The way we structure our Pen Tests aligns closely with the steps taken by bad actors to target and compromise your systems. We replicate the approach of real-world adversaries to simulate and evaluate how your systems and processes respond to a cyber attack.

1. Planning and Scoping

2. Research, Reconnaissance and Enumeration

3. Threat Analysis

4. Exploitation

5. Reporting

6. Remediation

One of our CREST, CHECK, and Cyber Scheme certified consultants will work with you to define the scope of the engagement and ensure that our tests will fulfil your requirements.

Your assigned consultant will gather information on your organisation, including:

IP addresses of websites and MX records
Details of e-mail addresses
Social networks
People search
Job search websites

This information will assist in identifying and exploiting any vulnerabilities or weaknesses.

Within the Threat Analysis stage we will identify a range of potential vulnerabilities within your target systems, which will typically involve a specialist engineer examining:

Attack avenues, vectors, and threat agents
Results from Research, Reconnaissance and Enumeration
Technical system/network/application vulnerabilities

We will leverage automated tools and manual testing techniques at this stage.

Once we have identified vulnerabilities, we will attempt to exploit them in order to gain entry to the targeted system.There are three phases to this stage:

Exploit – use vulnerabilities to gain access to a system, e.g. inject commands into an application that provide control over the target.

Escalate – attempt to use the exploited control over the target to increase access or escalate privileges to obtain further rights to the system, such as admin privileges.

Advance – attempt to move from the target system across the infrastructure to find other vulnerable systems (lateral movement) potentially using escalated privileges from target systems and attempting to gain further escalated privileges and access to the network.

Your Penetration Test Report will detail any identified threats or vulnerabilities, as well as our recommended remedial actions. Threats and vulnerabilities will be ranked in order of importance. The report will also contain an executive summary and attack narrative which will explain the technical risks in business terms. Where required, we can arrange for your CyberLab engineer to present the report to the key stakeholders within your organisation. You can download an example Penetration Test report.

The report will provide information on remedial actions required to reduce the threats and vulnerabilities that have been identified. At this stage, we can provide you with the additional consultancy, products, and services to further improve your security posture.
