What CYSIAM does
CYSIAM is a UK-based managed cybersecurity and cyber resilience services provider, founded in 2019 and headquartered in Newport Pagnell, Buckinghamshire, with a London office (Westminster) and a registered office in Wells, Somerset. The company delivers an integrated service portfolio spanning Cyber Threat Intelligence (including CTI-as-a-Service and threat modelling), Managed Detection & Response delivered from a wholly UK-based 24x7/365 Security Operations Centre, Incident Response (retainer, readiness review, NCSC-assured Cyber Incident Exercise), and Consulting services (Cyber Capacity Building and Maturity Assessment). Its core technical asset is a proprietary Cyber Threat Intelligence platform partly informed by collaboration with over 700 global Incident Response Teams, combined with a Cyber Defence Operations service that integrates CrowdStrike Falcon (EDR, Next-Gen SIEM, OverWatch) as its underlying endpoint and detection technology stack.
The business model combines recurring managed service revenue (MDR subscriptions, CTIaaS, Incident Response retainers) with project-based consulting (capacity building, maturity assessment, training delivered with Cranfield University) and ad-hoc emergency response work. Go-to-market is consultancy-first, sold through direct senior engagement, Crown Commercial Service frameworks (Cyber Services 3, DOS4, G-Cloud 11, R-Cloud), and channel partnerships, most notably with CrowdStrike (Rising Star Partner of the Year 2025) and KPMG on the FCDO Digital Access Programme. The firm raised £1.15 million from Maven VCTs in 2023 as its first external capital, and operates with a relatively flat, veteran-led management team.
Customer concentration is weighted towards UK government and defence (MOD supply chain, central government frameworks), international governments receiving FCDO-funded cyber capacity building (delivered across more than 25 countries including Kenya, Nigeria, South Africa, Brazil, and Indonesia), and enterprise clients in legal and financial services. The company's competitive positioning rests on a stack of difficult-to-replicate accreditations (NCSC Cyber Incident Response Level 2, CREST SOC, FIRST Full Membership, JOSCAR, ISO 27001/20000/9001) and a wholly UK-based, HMG security-cleared workforce with government and military cyber operations backgrounds, positioning CYSIAM as a boutique, high-credibility provider to nationally significant clients rather than a volume enterprise vendor.
