Source code review

Our in-depth review of your source code will identify underlying issues in the codebase, which could be exploited by a third-party or disgruntled former employee.

Internal & external infrastructure

Our expert consultants will examine your internal and external infrastructure for potential security vulnerabilities to protect your business and keep you one step ahead of hackers.

Cloud security assessments

Cloud deployments can be more vulnerable than standard hardware-based deployments due to the wider access. We perform a comprehensive configuration review of your cloud environment.

Secure configuration review

Often IT configurations are based on default setup, complete with default passwords. Our review will identify any vulnerabilities in your setup and configurations before attackers do.

Wi-Fi security assessment

Our experienced team will ensure your available Wi-Fi networks are not vulnerable to misuse. They will determine any encryption weaknesses and demonstrate how easily a poorly protected network can be accessed.

API testing

Security Assessment of web services typically covers data validation, access control and business logic flaws. We will test the web services in scope by posing as a trusted client and constructing requests to subvert security.

What is a vulnerability assessment?

The objective of a vulnerability assessment is to systematically identify, quantify and prioritise vulnerabilities for a given system within a set timeframe.

A comprehensive vulnerability testing will combine manual human analysis with automated scanning techniques.

As part of the reporting, remediation or mitigation advice will usually be provided to help you overcome any vulnerabilities discovered.

What can a vulnerability assessment test?

A vulnerability assessment can target web and mobile applications, external and internal networks, and API endpoints. The assessments will test for ways to authentication, broken access controls, injection points, data validation and sanitisation issues, vulnerable and outdated components, server-side request forgery (SSRF), cryptographic failures, among others.

What vulnerability assessment tools do you use?

Threats and vulnerabilities are evolving all the time. Therefore, our toolkit includes the best commercial and open-source solutions as well as bespoke tools developed in-house.

What's the difference between a vulnerability assessment and a penetration test?

A vulnerability assessment aims to identify potential vulnerabilities in an environment, such as a network, web or mobile application. It will be broader in scope and not go too in-depth in trying to exploit identified vulnerabilities. A penetration test will be much more focused on ethically exploiting any identified vulnerabilities within the agreed time frame. It will be often limited to a particular system or application. A “pen test” is much more thorough and time-consuming.

How often is a vulnerability assessment required?

Ideally, a vulnerability assessment will be carried out once a year or, in the case of a particular application, whenever there are code changes or new features are introduced.

What is in my vulnerability assessment report?

Your comprehensive vulnerability assessment report will contain all findings categorised by their risk, including evidence, detailed steps to reproduce them, and advice on remediation steps.
