ASSURITY SYSTEMS LIMITED

What ASSURITY SYSTEMS LIMITED does

ASSURITY SYSTEMS LIMITED is a Bristol-based specialist cybersecurity distributor and consultancy (Company Number 11413693, founded 2018) that operates as the Official Sales & Marketing representative for EMEA and UK/European Distributor for AppGuard, a patented zero-trust kernel-level endpoint and server protection technology. The AppGuard product suite spans Enterprise, Server, Small Business, Solo (GBP 49.99 self-serve one-time licence) and Local Government editions, all leveraging a default-deny architecture that blocks malicious processes at the OS kernel regardless of whether threats have been seen before, eliminating dependence on signature updates. Assurity also owns and sells Validato, a threat-informed Breach & Attack Simulation platform that runs MITRE ATT&CK-mapped scenarios and maps results to NIST CSF/800-53 and ISO 27001 frameworks for SOC tuning, MSP evaluation, M&A due diligence and regulatory compliance testing (DORA, NIS2, GLBA).

The company runs a hybrid sales motion: direct enterprise field sales via demo requests targeting UK government bodies and corporates, an active reseller channel recruited through a dedicated Reseller Portal, and self-serve online purchase for AppGuard Solo. Revenue derives primarily from annual/subscription licences on AppGuard Enterprise and Server editions and Validato subscriptions, supplemented by one-time AppGuard Solo licences and reseller-sourced deals. The named customer base in public materials is concentrated on three anonymised UK local authorities with a former UK MOD Cyber Defence Unit endorsement, while operational footprint extends across the UK, Ireland, Western Europe and parts of the Middle East and Africa under corporate global policies. The leadership bench disclosed in source materials is limited to Colin Jupe as Director of Strategy and Data Protection Officer, consistent with a small, specialist distribution-led operation rather than a scaled software vendor.

Core offering

Assurity Systems is a specialist cyber security consultancy and distributor that supplies and supports two technology lines in the UK and EMEA: AppGuard, a patented zero-trust, kernel-level endpoint and server protection platform sold in Enterprise, Server, Small Business, Solo and Local Government editions, and Validato, a threat-informed defence platform that uses Breach & Attack Simulation based on MITRE ATT&CK to validate the effectiveness of customer security controls. The company combines direct enterprise sales, self-serve online purchase for small customers and a reseller channel to deliver these solutions alongside cyber defence consulting.

Product overview

ASSURITY SYSTEMS LIMITED offers a portfolio of two distinct product lines distributed across the UK and EMEA region. The first is AppGuard — a suite of zero-trust, kernel-level endpoint and server protection products spanning Enterprise, Server, Small Business, Solo (self-service), and Local Government editions — all powered by the same patented zero-trust technology that blocks malicious processes by default without signature-based detection. The second is Validato — a standalone threat-informed defence and breach & attack simulation platform that allows organisations to safely test their resilience against cyber threats by simulating scenarios based on MITRE ATT&CK Techniques and mapping results to NIST CSF/800-53 and ISO 27001 control frameworks.

Functional benefit

Products and services

• AppGuard Enterprise Centrally managed, host-based endpoint protection solution that uses AppGuard's patented zero-trust kernel-level technology to prevent malware and advanced attacks by blocking malicious processes before they can detonate; designed for enterprise and government customers.
• AppGuard Server Zero-trust, host-based protection agent for Windows and Linux servers, centrally managed alongside laptop and desktop agents from the same AppGuard management console, providing server-grade cyber defence using the same patented pre-detection blocking technology as the rest of the AppGuard range.
• AppGuard Solo Self-managed zero-trust, host-based endpoint protection agent for Windows laptops and desktops, sold as a one-time purchase of GBP 49.99 + VAT for individuals and small businesses with fewer than 20 users, with a 1MB on-disk and 10MB memory footprint.
• AppGuard Small Business Edition Full-featured AppGuard zero-trust endpoint protection tailored for small and medium-sized businesses, offering lightweight (1MB on hard drive, 10MB memory), set-and-forget operation that does not require internet connectivity or ongoing policy management.
• AppGuard for Local Government Zero-trust endpoint protection packaged specifically for UK councils and local government organisations, designed to defend against phishing, ransomware, polymorphic malware and other modern threats targeting the public sector.
• Validato Threat-informed defence platform that uses Breach & Attack Simulation (BAS) to safely simulate cyber threat scenarios based on MITRE ATT&CK Techniques, mapping results to NIST CSF, NIST 800-53, ISO 27001 and MITRE SHIELD frameworks; used by IT and information security teams for MSSP validation, SOC tuning, EDR comparison, vendor due diligence and compliance with DORA, NIS2 and GLBA.

Direct peers

• AttackIQ: Breach and Attack Simulation (BAS) platform mapped to MITRE ATT&CK. The most direct competitor to Assurity's Validato product, serving enterprise SOCs and MSSPs with continuous security validation.
• Exclusive Networks: Global cybersecurity value-added distributor with deep EMEA footprint. Closely comparable to Assurity as a specialist distributor of niche endpoint/network security vendors into UK and European enterprise and government channels.
• SafeBreach: BAS platform for validating security controls against MITRE ATT&CK techniques. Competes directly with Validato in the enterprise security validation market and would be considered alongside it in customer bake-offs.
• Cloud Distribution (Pulsant): UK value-added distributor focused on cybersecurity and cloud technologies. Closely comparable to Assurity as a UK cybersecurity distributor building a channel around niche security ISVs.

Emerging players

• XM Cyber: Attack path management and breach simulation vendor. Comparable to Validato's BAS use case (continuous control validation) but adds exposure-management angle, addressing overlapping CISOs.

Broad incumbents

• CrowdStrike: Global leader in endpoint protection (Falcon platform) and incident response. Directly competes with AppGuard for enterprise and government endpoint budgets, with substantially larger sales, R&D and channel investment.
• SentinelOne: AI-driven endpoint security (Singularity) platform competing head-on with AppGuard's prevention-first positioning. Comparable as an enterprise endpoint security incumbent Assurity is benchmarked against in customer deals.
• Cybereason: Endpoint detection and response (EDR/XDR) vendor competing for the same enterprise endpoint wallet as AppGuard, with its own channel programme that competes with Assurity's reseller motion.
• Darktrace: UK-headquartered AI cybersecurity vendor selling into enterprise and government. Comparable as a UK-rooted cyber vendor competing for the same buyer budgets, though Darktrace's self-learning detection contrasts with Assurity's prevention-and-validation model.
• Sophos: UK-headquartered endpoint and network security vendor serving SMB, enterprise and public sector. Comparable to Assurity's AppGuard line as a UK-rooted endpoint security alternative, but at vastly greater scale and with owned (not distributed) technology.
