Horizon3 Earns Cyber Essentials Certification Covering NodeZero EU Network

[Mary Brown]

Horizon3, a prominent provider of autonomous security solutions, has officially achieved Cyber Essentials Plus certification for its AWS EU infrastructure. Securing top-tier proactive cybersecurity compliance through rigorous independent evaluation validates the baseline security posture of the cloud network behind NodeZero. The certification specifically covers the AWS EU network infrastructure that powers Horizon3’s regional operations and data sovereignty hosting in Germany. Issued on September 22, 2026, the certification is valid through September 22, 2027, marking an important compliance benchmark for organizations managing sovereign European workloads.

The formal validation demonstrates that the supporting cloud environment adheres to essential technical controls established under the UK’s National Cyber Security Centre (NCSC) framework. By validating foundational controls across firewalls, secure system configurations, user access management, patch updating, and malware protection, Horizon3 offers heightened transparency to enterprise clients and government partners operating across the UK and the European Union.

Rigorous Technical Controls for Cloud Infrastructure​

Cyber Essentials Plus requires hands-on technical auditing and vulnerability testing to confirm that security controls operate effectively in practice. The scope of this certification covers the primary NodeZero AWS EU network infrastructure alongside associated employee remote access networks.

The audit verified essential defenses against common internet-based threats:

• Boundary Firewalls and Internet Gateways: Ensuring robust network segmentation and traffic filtering to restrict unauthorized external access.
• Secure Configuration: Maintaining strict baseline settings across cloud instances and administrative consoles to minimize unnecessary exposure points.
• User Access Control: Enforcing least-privilege principles and multi-factor authentication (MFA) across administrative accounts.
• Patch and Vulnerability Management: Confirming that system updates and software patches are systematically applied within designated timelines.
• Malware Protection: Utilizing automated endpoint detection and continuous threat protection across all supporting endpoints.

Enhancing Assurance for Regional and Enterprise Clients​

As enterprises increasingly rely on autonomous pen-testing tools to uncover exploit paths in production environments, proving the safety and operational security of the underlying SaaS architecture is paramount. Customers evaluating third-party platforms require verifiable proof that provider environments satisfy recognized baseline standards.

Achieving this certification simplifies third-party risk assessments for European organizations, particularly public sector entities and defense contractors in the UK that mandate Cyber Essentials compliance for supplier ecosystems. The verification confirms that while NodeZero conducts continuous safety testing on customer environments, its own supporting EU data infrastructure adheres to established international security standards.

Autonomous Security and European Data Sovereignty​

NodeZero operates as an AI-native proactive security platform designed to continuously evaluate enterprise attack surfaces at machine speed. By executing non-disruptive, autonomous pen-tests, the platform uncovers chained attack paths and prioritizes actionable remediation tasks before threat actors can exploit them.

The Cyber Essentials Plus milestone complements Horizon3's commitment to European data sovereignty. With data centers located in Germany, regional customers maintain control over their diagnostic data while benefiting from localized regulatory alignment, including GDPR and NIS2 compliance frameworks.

Commitment to Continuous Security Improvement​

Achieving Cyber Essentials certification forms part of Horizon3's broader initiative to continuously harden its global operational infrastructure. As organizations face increasingly sophisticated threat vectors, combining continuous autonomous attack testing with verified cloud governance ensures that defensive posture security evolves alongside emerging risks.

The company plans to maintain annual certification renewals and continue expanding its regional compliance accreditations to support expanding global deployment models.
