Source code security assessment

Source code security assessment

Your application's code is its foundation. We manually review your source code line by line to find hidden vulnerabilities, logical flaws, and security issues before they can be exploited by attackers.

Threat Modelling

Threat Modelling

Before you write a line of code, we help you think like an attacker. We work with your development team to map out potential threats to a new system and plan its defences from the very start.

  API Penetration Testing   APIs are the backbone of modern applications, handling all the communication. We test these critical connections to find security flaws that could lead to data breaches or allow attackers to take control of your services.

AI Pen Testing and Red Teaming

AI Pen Testing and Red Teaming

Go beyond standard tests. Red Teaming is a full-scale attack simulation against your organisation to test your people, processes, and technology. We also specialise in testing AI systems, finding unique vulnerabilities in machine learning models.

IoT Pen Testing

IoT Pen Testing

From smart office devices to industrial sensors, connected devices are a common target. We test your "Internet of Things" hardware, firmware, and communication methods to find weaknesses before they're used against you.

Penetration Testing

Penetration Testing

We test your systems, websites, and apps by simulating a real cyber-attack. This hands-on testing finds security holes that automated tools often miss, giving you a true picture of your security
