Web application penetration testing

Web application penetration testing

Personal approach and in‑depth knowledge

Available to hackers 24x7 and brim-full of data, web applications present a tempting target for hackers. We provide clear reports with steps to reproduce vulnerabilities, exploitation probability and actionable recommendations.

Infrastructure penetration testing

Infrastructure penetration testing

Don’t give a hacker an opportunity

Hackers will be looking for ways of entry into your network, and when they are in, ways to access sensitive data. Testing your network and security infrastructure is key.

Mobile application penetration testing

Mobile application penetration testing

Checking your app is coded securely

With the huge proliferation of mobile applications comes the need for robust security testing. We identify vulnerabilities and validate that the application is secure.

Continuous Security Testing

Continuous Security Testing

Combining industry-leading application-scanning technology and the expertise of senior penetration testers

Gain insight into vulnerabilities significantly faster than through traditional penetration testing with vulnerability notifications as new high-impact issues arise.

Red Team exercises

Red Teaming

A Red Team exercise is an all-out attempt to achieve the defined objectives by any methods available

This usually includes assessments with specific objectives in mind in order to simulate tactics, techniques and procedures used by real world adversaries.

Social Engineering

Social Engineering

Your best defensive strategy against social engineering is to raise employee security awareness and to educate on good practices

Typical Social engineering engagements include managing phishing campaigns, testing physical entry procedures, baiting and watering hole attacks to ensure you are maximising the protection within your organisation.

Code Review

Code Review

Spot issues in your code before they are found in production

In depth security review of your source code by using a combination of manual and automated checks to look for security flaws and insecure coding practices inside the source code which can lead to serious security risks.

Code Review

Cloud Security

Make sure your cloud transformation is a secure one

Test applications and infrastructure hosted in public cloud environments, including security assessments of cloud environment configurations.
