Our origins are in hunting threats and securing complex environments in the world’s single most targeted industry—financial services. With two decades of experience in thwarting dynamic, advanced persistent threat campaigns, we have scaled our cybersecurity services to eliminate critical cyber threats, reduce cyber risk, and put our customers’ business ahead of disruption. We stop threat actors in their tracks, disrupting attacks before they become business-disrupting events. Others claim it. We prove it – with world-class original security research, no table breach discoveries, and transparent threat dissections.
Protrona is a London-based managed security service provider (MSSP) and a specialised branch of Fitzrovia IT focused solely on cybersecurity. Our attention, expertise, and resources are dedicated entirely to protecting our clients rather than being spread across broader IT services. We hold all six Microsoft Solutions Partner designations; a distinction held by only a small number of UK providers, alongside ISO 9001, 14001, 22301, 27001 and 45001 certifications, reflecting genuine technical depth and a commitment to quality, security, resilience and continuous improvement.
Specops helps organizations close the identity gaps attackers exploit. From password security and identity verification to secure account recovery and device trust, our IAM solutions protect users across Active Directory, Entra ID, and hybrid environments.
