UK Remote Security Assessment System (RSAS) Market Beneficial Analysis and Key Vendors - FireEye, Pentest People, Kroll, SBS CyberSecurity
The UK RSAS market is poised for rapid expansion as organizations accelerate digitalization and adopt hybrid-work operating models. Over 2025-2032 the domestic market is forecast to grow at a 10.9 % CAGR, reaching an estimated £1.2 billion by 2032, up from roughly £0.55 billion in 2024. Growth is underpinned by the rising cost of cyber incidents—UK businesses reported a 35 % YoY increase in material breaches during 2024—and by ever-tighter compliance obligations that require independent, continuous security validation.
Key technological trends include the migration from periodic point-in-time testing to always-on, API-driven “continuous automated red-teaming” platforms. AI/ML engines now correlate telemetry from cloud workloads, OT devices and SaaS APIs to surface exploitable attack paths in near-real-time. Simultaneously, low-code orchestration is lowering the barrier to integrate RSAS outputs directly into DevSecOps pipelines, enabling “shift-left” remediation at build time rather than after deployment. Edge computing and 5G are also reshaping architectures: sensors embedded at branch sites stream vulnerability and posture data back to UK-hosted assessment hubs, reducing latency while satisfying the UK’s data-residency requirements.
From a service-delivery perspective, demand is moving toward outcome-based subscriptions. Customers increasingly purchase “exposure-hours-reduced” or “compliance-gaps-closed” SLAs rather than scanner licences. This is fostering collaboration between managed cyber-defence providers and insurers that use RSAS evidence to fine-tune cyber-premium pricing. Finally, sustainability considerations are emerging: cloud-native RSAS platforms consume as little as one-tenth of the energy of on-premise scanners, dovetailing with UK government net-zero mandates for large enterprises by 2035.

Although this study centres on UK demand, global dynamics influence domestic procurement strategies. Europe commands the second-largest share after North America, with GDPR, NIS 2 and the forthcoming EHDS driving spend on persistent assessment platforms. The UK mirrors mainland trends but applies additional oversight via the National Cyber Security Centre (NCSC), which mandates remote vulnerability discovery for all critical infrastructure operators.
North America remains the innovation hub, accounting for nearly 38 % of global RSAS revenue in 2024 thanks to aggressive cloud adoption and SEC incident-disclosure rules. Many UK-based multinationals benchmark their security roadmaps against U.S. regulatory best practices, importing platform standards and assessment cadences.
Asia-Pacific is the fastest-growing territory (~15 % CAGR) as India, Japan and ASEAN economies enforce new cyber-resilience laws; this fuels vendor R&D investment that trickles into UK offerings—particularly in AI-enabled exploit simulation.
Latin America and Middle East & Africa remain nascent but important; UK service firms increasingly deliver follow-the-sun RSAS support from operations centres in Mexico City, Dubai and Johannesburg, providing cost-effective expertise that ultimately benefits UK customers.

A Remote Security Assessment System aggregates automated scanners, exploit simulators and analytics engines to evaluate an organization’s security posture without on-site presence. Core modules include external-attack-surface mapping, credential-safe penetration testing, configuration drift analysis and compliance gap scoring. Assessments are delivered via dashboards or as machine-readable JSON to CI/CD pipelines, enabling rapid remediation.
In the UK, RSAS adoption aligns with three macro-shifts: (1) accelerated cloud migration—82 % of UK enterprises host mission-critical data in public clouds; (2) hybrid labour models—approximately 46 % of full-time employees now work remotely at least two days a week; and (3) a national push toward digital trade, increasing exposure of APIs and micro-services. Together these dynamics elevate the strategic importance of always-on remote assurance.
Applications extend across regulated verticals (finance, healthcare, critical infrastructure) and horizontal IT operations such as vulnerability management, zero-trust validation and cyber-insurance underwriting. By 2032, RSAS is expected to form the backbone of UK enterprise cyber-governance, replacing annual manual penetration tests with evidence-rich, regulator-auditable artefacts.

Three factors underpin the UK market’s 10.9 % forecast CAGR. First, escalating threat volumes: recorded cyber-crime losses in the UK exceeded £3.1 billion in 2024, fuelling demand for proactive, remote-first defence strategies. Second, legislative momentum: NIS 2 transposition and revisions to the UK Data Protection Act introduce heavier breach penalties and explicit continuous-testing clauses. Firms therefore view RSAS not merely as best practice but as compliance insurance. Third, cloud-centric digital transformation: by 2027, 95 % of mission-critical UK workloads are projected to run in public or hybrid clouds. RSAS becomes indispensable for validating transient, containerised assets lifespans measured in minutes.
Other accelerants include maturation of AI tooling, which slashes false-positive ratios by learning organization-specific exploit likelihood; growth of cyber-insurance markets requiring independent verification of controls; and heightened board-level accountability, with 72 % of FTSE 350 companies now featuring cybersecurity as a standing agenda item.

Rising attack surface from IoT/OT convergence.
Government grants supporting cyber-resilience for SMBs.
Falling cloud-compute prices lower barrier to enterprise-grade assessment engines.
Vendor-agnostic APIs enable RSAS to integrate with SOAR, SIEM, ITSM tools, maximizing ROI.
Despite robust tailwinds, several headwinds threaten to temper growth. Capital outlay and OPEX remain high for comprehensive coverage—particularly when factoring internal remediation resources. Skills shortages exacerbate costs; the UK cyber-skills gap stood at 11,200 unfilled roles in 2024, delaying RSAS deployment and interpretation. Standardization lags: absence of universally accepted RSAS efficacy metrics breeds buyer hesitation and complicates procurement benchmarking.
Additionally, data-sovereignty concerns restrict some sectors from using multi-tenant cloud environments, necessitating more expensive UK-hosted or on-premise instances. Integration complexity with legacy OT environments can prolong roll-outs, while false-positive fatigue risks eroding stakeholder trust if analytics are not finely tuned. Lastly, economic uncertainty and cybersecurity budget scrutiny in a high-inflation environment may defer large-scale RSAS investments among cash-constrained SMEs.
