Segment Analysis

By Offering: Services Command Spending As In-House Skills Erode

Services captured 62.73% of UK cybersecurity market share in 2025, and this slice is projected to widen at a 12.22% CAGR. Managed detection and response has become the fastest-growing line item because enterprises can activate cloud sensors within days and receive round-the-clock threat hunting for a recurring fee that is simpler to budget than staffing an internal security operations center. Professional services demand also rises as compliance mandates proliferate and boards commission gap analyses, penetration tests, and resilience rehearsals. In contrast, the solutions segment remains essential but lags in percentage growth, with buyers favoring cloud-native tools that bundle firewall, zero-trust network access, and secure web gateway features into a single subscription. Identity and access management ranks as the most consistently purchased solution because zero-trust designs rest on strong authentication and least-privilege authorizations. Application security tooling attracts software-as-a-service vendors that integrate static, dynamic, and software composition analysis into continuous-integration pipelines. Despite steady interest in endpoint, network, and data security products, spending tilts toward service engagements that wrap expert oversight around these technologies.

The UK cybersecurity market size for services is forecast to accelerate further as public entities mandate that critical suppliers hold round-the-clock security monitoring certifications. Meanwhile, vendors that operate multiple regional security operations centers hedge latency risks, meet data-residency clauses, and guarantee continuity in the event of localized outages. Multiyear outsourcing is therefore likely to reach a higher penetration rate among both highly regulated industries and mid-market firms that once relied on reactive outsourcing on an ad-hoc basis.

By Deployment Mode: Cloud Solutions Dominate As Perimeter Dissolves

Cloud captured 63.84% of UK cybersecurity market size in 2025, growing at a 12.32% CAGR, while on-premise deployments expand at mid-single-digit rates. Remote and hybrid workforces require identity-centric architectures, so organizations adopt security service edge platforms that enforce consistent policies across any location. Government and financial regulators endorse multi-cloud strategies paired with centralized identity federation, which further validates vendor roadmaps built around cloud-first controls. Enterprises note that activating cloud protection can take days, whereas procurement, racking, and maintenance cycles slow on-premise platforms. Even industries with strict data localization rules embrace hybrid designs that keep sensitive records onsite but shift analytics to elastic cloud nodes.

On-premise estates persist in segments that run legacy operational technology, such as manufacturing, energy, and utilities. Air-gapped programmable logic controllers cannot interface with external platforms, so asset owners deploy intermediary sensors and network taps to gain telemetry. Vendors blend these deployments with cloud-hosted management consoles, which illustrates the broader trend toward flexible consumption models. However, migration introduces misconfiguration risks, and cloud security posture management is now bundled into most enterprise contracts to check compliance against Center for Internet Security benchmarks automatically.

By End-User Industry: Healthcare Growth Surges As BFSI Remains Core

Banking, financial services, and insurance retained 29.73% of UK cybersecurity market share in 2025, a position underpinned by continuous regulatory scrutiny from the Financial Conduct Authority and the Prudential Regulation Authority.[3] Budgets cover zero-trust migration for trading platforms, continuous monitoring of third-party vendors, and automated reporting for operational resilience tests. Healthcare, however, records the swiftest expansion with a 13.67% CAGR through 2031. Ransomware assaults on hospital trusts in 2025 triggered elective surgery delays and forced a government-backed GBP 250 million uplift program that funds endpoint detection, network segmentation, and encrypted backups. Moreover, electronic health record modernization goes hand in hand with enhanced identity management to protect sensitive patient data.

Government ministries and local councils also enlarge spending to satisfy zero-trust mandates that now form mandatory contractual language for all departments. Telecommunications operators invest heavily to swap high-risk 5G components and harden signaling. Retail and e-commerce entities deploy fraud detection and tokenization to stem an 18% rise in card-not-present transactions. Manufacturing and industrial sectors focus on network segmentation inside supervisory control networks, while energy utilities adopt anomaly detection sensors to monitor power-generation turbines. Despite varied priorities, every vertical now views cybersecurity as a board-level operational requirement rather than an IT line item.

By End-User Enterprise Size: SME Adoption Gains Momentum Under Insurance Pressure

Large enterprises accounted for 61.74% of 2025 spend, supported by in-house security engineering staff and multi-layered defenses that cover endpoints, networks, and cloud workloads. Growth in this tier is steady but incremental, given that many large organizations already operate mature security programs. Small and medium enterprises, by contrast, log a 12.46% CAGR, catalyzed by cyber-insurance underwriters that refuse cover unless buyers implement multi-factor authentication, maintain up-to-date software, and store offline backups. Insurers leverage actuarial claims to adjust pricing in real time, so SMEs quickly realize that even a modest investment in baseline controls can cut premiums by tangible percentages.

The UK cybersecurity market size for SMEs remains smaller on an absolute basis, yet the addressable headcount of 5.5 million businesses makes the collective opportunity substantial. Vendors tailor bundles that fold endpoint, email, and web protection into a single agent, add managed detection oversight, and expose simplified dashboards suitable for non-specialists. Consumption-based packages resonate because SMEs can scale up during peak trading seasons and scale down afterward, flattening cost curves. As compliance pressures, insurance audits, and customer expectations converge, SME adoption deepens, closing the maturity gap versus large enterprises.

Geography Analysis

London and the Southeast dominate UK cybersecurity outlays, representing about 38% of national spend in 2025. The capital hosts a dense cluster of financial institutions, global law firms, and technology unicorns that each operate multi-cloud estates and face high regulatory hurdles. Consequently, suppliers concentrate sales teams and demonstration centers inside the M25 corridor. Scotland ranks second as Edinburgh’s finance quarter and Glasgow’s maturing tech scene secure resources through the Scottish Government’s GBP 15 million Cyber Resilience Strategy, which funds SME security upgrades and university laboratories. Regional managed service providers fill skills gaps by co-locating operations centers near universities to tap graduate pools.

The Midlands and Northern England exhibit moderate but accelerating demand as manufacturing and logistics hubs digitize supply chains. Here, operational technology security drives purchases of anomaly detection sensors and network segmentation gear, reflecting threats posed by nation-state actors probing industrial control systems. Wales and Northern Ireland remain smaller in absolute terms, yet government grants encourage local councils and hospitals to migrate email, productivity software, and security controls to sovereign cloud platforms. Devolved cybersecurity strategies incentivize managed service providers to open satellite offices, ensuring on-the-ground incident response without lengthy travel.

Cross-border regulatory alignment further molds the landscape. Post-Brexit, UK regulators mirror the European Union’s Digital Operational Resilience Act to facilitate trade in financial services, so multinationals insist on tools that satisfy both rulebooks. Participation in Five Eyes intelligence networks provides early warning of zero-day exploits, influencing vendor patch management timelines. Finally, joint exercises under NATO’s Cooperative Cyber Defense Centre sharpen military and civilian readiness, translating into procurement of devices hardened to common evaluation assurance level benchmarks.

Competitive Landscape

The market is moderately fragmented, with the five largest vendors, Darktrace, Sophos, NCC Group, BAE Systems Digital Intelligence, and BT Security, holding a 35% share in 2025. Darktrace capitalizes on machine-learning analytics that automatically quarantine anomalous behavior, winning contracts in sectors pressed by the cyber-skills shortage. Sophos differentiates through a global network of security operations centers that deliver managed detection and response aligned to mid-market price points. NCC Group leverages its deep penetration-testing roots to advise banks and telecom operators on their obligations under the Telecom Security Act and DORA.

Second-tier specialists, including Bridewell Consulting, Integrity360, and Quorum Cyber, capture niches by marrying domain knowledge with flexible commercial models. Bridewell helps healthcare trusts comply with National Health Service governance, while Integrity360 focuses on DevSecOps and cloud posture for software-as-a-service vendors. Strategic partnerships increasingly determine success. BT Security wraps Microsoft Sentinel analytics into its managed extended detection and response stack, giving clients unified insight across on-premise and multi-cloud assets. BAE Systems Digital Intelligence leverages sovereign data-handling assurances to secure defense contracts that require classified threat intelligence.

Innovation hotspots revolve around operational technology isolation, consumption-based licensing, and autonomous response. Darktrace’s 2026 product launch that shields programmable logic controllers without halting production exemplifies the trend toward harmonizing IT and OT security. Meanwhile, Immersive Labs trains cyber teams via gamified simulations, addressing talent shortages that otherwise impede technology rollouts. Certification schemes from the UK Cyber Security Council introduce standardized professional tiers, which reduces vendor differentiation based solely on staffing credentials and pivots competitive emphasis to the measurable efficacy of detection algorithms and integration breadth.

Detailed Research Methodology and Data Validation

Primary Research

Mordor analysts interviewed CISOs at banks, NHS trusts, energy operators, and fast-growing fintechs across England, Scotland, and Wales, alongside MSSP product leads and former NCSC assessors. Conversations validated price bands, adoption lags among SMEs, and the real-world impact of regulatory deadlines, filling data gaps flagged during desk work.

Desk Research

We began with public datasets from the Department for Science, Innovation and Technology, the National Cyber Security Centre breach surveys, Ofcom telecom security filings, HMRC trade codes, and pan-European notices issued under GDPR and the upcoming DORA rules. Company 10-Ks, prospectuses, and investor decks helped us benchmark vendor segment splits, while academic journals such as Computers & Security clarified attack-vector prevalence. Paid libraries, D&B Hoovers for revenue splits and Dow Jones Factiva for deal flow, supplemented open sources when recent numbers were scarce. This list is illustrative; many additional materials were consulted for cross-checks and context building.

Market-Sizing & Forecasting

A top-down model draws on DSIT revenue totals and Customs import data, which are then segmented by offering and end-user through penetration-rate adjustments derived from breach-incident ratios and average security spend per employee. Supplier roll-ups and sampled average-selling-price × volume checks provide a bottom-up lens that guides final weighting. Core variables include (i) number of ICO-reported breaches, (ii) cloud workload share of UK enterprise IT, (iii) ransomware incident count from Police CyberCrime Unit logs, (iv) regulated-sector security budget index, and (v) GBP-USD exchange path. Forecasts to 2030 employ a multivariate regression that links these drivers to historic spend and tests three demand scenarios agreed with interviewees; gaps in granular vendor data are bridged with channel-check derived ratios.

Data Validation & Update Cycle

Before sign-off, independent analysts run variance screens against external revenue tallies, DSIT growth signals, and macro indicators. Outliers trigger re-contacts with domain experts. The report is refreshed each year, and mid-cycle updates are issued when material events, such as the Cyber Resilience Bill's passage, shift the baseline.

Why Mordor's UK Cybersecurity Baseline Is Trusted

Published estimates often diverge because research houses pick different spending buckets, exchange-rate bases, or refresh cadences.

Key gap drivers here include varying treatment of hardware-centric sales, inclusion of adjacent insurance or physical security outlays, and whether managed services are counted separately or folded into solutions. Mordor's scope mirrors government taxonomy, applies current-year average FX, and is updated annually, which limits drift.
