Providing realism and a combined Red-Blue approach to Cybersecurity Training
Understand Attacker tactics.
Defence requires a good understanding your adversary and other potential threats to your organisation and yourself. Our approach ensures that you understand what threats do and how threats look like, so that you can proactively defend against them and identify their indicators in a live scenario or in forensics. Especially, when the bad guys become more sophisticated.
Understand Defender capabilities.
Basic vulnerability assessments and pentesting attempts mostly fail in the presence of monitoring, detection and response tools. Even custom malware eventually gets detected over time in longer-term engagements. Our approach shows you what you're up against, so you can perform security assessments that evade what the defender has deployed, and possibly use that to your advantage.

On-demand, online courses
The on-demand courses cater to learners wishing to hone their skills in a remote training, lab-based environment. Experienced instructors are also on-hand to provide guidance, both in a remote setting, and optionally in-person on a regular schedule. These courses cover both Red and Blue team perspectives, and culminate in an optional certification attempt.
