Real-world outcomes from our engagements with the UK's most critical organisations.
Following a near-miss ransomware incident, the Group CISO needed to transform security posture within 12 months to satisfy PRA requirements and avoid a potential £50M regulatory fine. The bank had no centralised threat detection capability and relied on a legacy SIEM that hadn't been tuned in three years.
Deployed SentinelXDR across 18,000 endpoints, integrated ClearSIEM with 120+ data sources, and transitioned to our 24/7 SOC as a Service within 90 days. Followed by a full CBEST-aligned red team assessment to validate the new defensive posture.
"UK Cyber Security transformed our posture from reactive to proactive. SentinelXDR alone paid for itself within six months."
— Group CISO, Major UK Retail BankRansomware took clinical systems offline for 11 days, impacting patient care across three hospital sites. The trust needed immediate IR support and a long-term security transformation programme ahead of an upcoming CQC inspection.
Contained the breach and restored all critical clinical systems within 72 hours. Delivered a 12-month transformation including ShieldEDR deployment across 6,000 endpoints, VaultIAM rollout to eliminate shared credentials, and Cyber Essentials Plus certification.
"The IR team were on-site within 4 hours of our call. They saved us from what could have been a catastrophic situation for our patients."
— Director of Digital, NHS Trust, North West EnglandOperations across 42 countries with fragmented security controls, no centralised cloud visibility, and NIS2 compliance obligations across all EU subsidiaries following significant M&A activity. The CISO had no visibility into cloud asset inventory.
Deployed CloudGuard across a hybrid multi-cloud environment (AWS + Azure), implemented ThreatLens for sector-specific threat intelligence, and delivered a global NIS2 compliance programme across all 14 EU entities within 9 months.
"CloudGuard gave us visibility we'd never had before. Within 30 days we'd remediated hundreds of misconfigurations we didn't even know existed."
— VP of Information Security, Global Logistics GroupIdentified as a high-value target by state-sponsored threat actors. NCSC escalated the threat level, requiring immediate detection uplift and a full NCSC CAF compliance programme across all 14 security objectives.

Founded by former GCHQ and NCSC professionals, we exist to make enterprise-grade cyber security accessible to every UK organisation.
UK Cyber Security Ltd was founded in 2015 by Dr. Sarah Chambers, former Deputy Director at the National Cyber Security Centre, with a clear mission: to give British organisations the defensive capability once available only to government.

We are an NCSC Assured Service Provider, CREST member company, CHECK-approved body and CBEST-approved threat intelligence provider. We were named UK Cyber Security Company of the Year at the SC Awards Europe in 2023 and 2025.
