Testing & Exercising: What is YFH?

6 Feb 2026

SIACO producing brand-new "your friendly hostile" video

YFH, stands for "Your Friendly Hostile" which is a core component of SIACO and our consultancy offering, delivering all exercising and testing projects.


We explore security performance and capability through friendly hostile replication.


Working with expert partners, we provide specialist ancillary services, including threat mapping, surveying and training programs. Our brand new video released later this year, will showcase what this looks like and how it can help organisations be better prepared and resilient to threats and security risks.


These friendly hostile and real-world activities, help organisations and their security teams better understand how to protect their site, safeguard their people, develop preparedness and training programs.


We ensure you and your security teams can detect real world hostile reconnaissance and suspicious activity at your site.
