The Black Team: The Overlooked Force in a Complete Cyber Security Strategy

When people think about cyber security, they often imagine firewalls, threat detection software, and teams of analysts monitoring network traffic. But cyber resilience is only as strong as its weakest door lock, badge reader, or unsuspecting receptionist. That’s where Black Team assessments come in, the physical counterpart to digital red teaming, designed to uncover real-world vulnerabilities that no amount of encryption can protect against.

Penetration Testing for Operational Technology (OT): A Practical Guide

Operational Technology (OT) environments like Supervisory Control and Data Acquisition (SCADA), Distributed Control Systems (DCS), and Programmable Logic Controller (PLC) based networks are the backbone of critical infrastructure and industrial processes. Unlike IT systems, their primary goal is availability and safety, not just confidentiality. As cyber threats increasingly target industrial systems, penetration testing for OT has become a vital activity in validating defences and uncovering weaknesses before adversaries do.

The Cost of a Breach vs. the Value of Penetration Testing: A Technical and Financial Perspective

Cyber threats are not just a technical challenge, they’re a strategic risk. With the average cost of a data breach reaching millions, businesses must shift from reactive defence to proactive security. One of the most effective ways to do this is through penetration testing, a controlled simulation of cyber attacks designed to uncover vulnerabilities before malicious actors do. This blog explores the technical foundation of penetration testing, its types, the step-by-step approach testers take, the financial comparison to breach response, and the critical importance of choosing accredited providers.
