- Risk of loss or damage to products passes to the Customer upon delivery.
6. Warranty

- Customers must notify the Company of any defects within the warranty period.

7. Liability

- The Company is not liable for any indirect, incidental, or consequential damages, including software or data damages.
- The Customer is reminded to ensure that adequate provision is made to prevent data loss or inconsistency. We recommend a 3-2-1 backup policy: 3 backups, 2 on-site, and 1 off-site.
8. Hardware Provisioning, Security Hardening, and Network Maintenance
8.1 Infrastructure Staging and Software Integrity.
- The Company warrants that all customer-bound server hardware and software images are provisioned, staged, and configured within a structurally isolated, multi-tiered network infrastructure. Staging environments are segmented via logical 802.1Q VLANs and protected by a boundary pfSense enterprise firewall employing a default-deny inbound posture, integrated DNS sinkholing, and automated Intrusion Detection Systems (IDS). At no point during production do customer environments interact with the Company’s corporate data networks or external unauthenticated traffic.
8.2 Security Hardening Baseline.
- Unless explicitly agreed otherwise in writing via a customised Statement of Work (SoW), all Ubuntu-based server deployments are pre-hardened to align with the Centre for Internet Security (CIS) Level 1 baseline. Compliance is programmatically validated utilising the official Ubuntu Security Guide (USG), targeting a minimum automated pass metric of 90%. Standard delivery configurations strictly mandate:
- (a) The absolute deactivation of interactive password-based SSH authentication and the complete disabling of SSH root logins;
- (b) The enforcement of key-based authentication utilising high-entropy 4096-bit cryptographic keys;
- (c) The restriction of client-facing ingress traffic exclusively to secure Cloudflare Tunnels, keeping public edge ports entirely closed to the internet;
- (d) The restriction of command-line administrative access solely to the Company’s internal technical staff via an isolated, encrypted Tailscale Mesh VPN utilising 4096-bit private keys deployed on local encrypted hardware. Customers are not granted access to the Company’s Tailscale infrastructure.
8.3 Ongoing Maintenance, Patch Management, and Service Term Limit.
- The Company retains operational responsibility for the ongoing lifecycle management and technical maintenance of the server operating system solely and strictly during the term of an active, fully paid service contract or customer subscription. During this active service term, the Company warrants that all critical and high-risk security patches will be deployed to the environment via the private management network within the standard National Cyber Security Centre (NCSC) mandatory 14-day compliance window from public release.
8.4 Termination of Support and Transfer of Liability.
- Upon the cancellation, expiration, or termination of the Customer’s active service contract for any reason, the Company’s maintenance obligations cease immediately. All responsibilities for security patching, vulnerability management, and systems compliance transfer entirely to the Customer on the exact date of termination. The Company will securely deprecate administrative Tailscale and Cloudflare Tunnel configurations upon contract closure.
8.5 Scope of Hardening and Client Liability.
- The Customer acknowledges that the 90% USG compliance rating reflects the optimal system-level configuration achievable while maintaining core operational functionalities. The remaining 10% variation accounts for environment-specific dependencies, including localised partition boundaries, custom application banner scripts, and variable container networking structures.
8.6 Post-Delivery Modification Restrictions.
- During the active service term, the Company maintains the underlying system integrity. The Company shall not be held liable for any security breaches, data loss, regulatory non-compliance (including UK Information Commissioner’s Office (ICO) infractions), or system instability arising from:
- (a) Unauthorised Customer modifications to the core security policies, pre-installed configurations, Cloudflare Tunnel parameters, or firewall profiles;
- (b) The application or installation of unsigned, third-party software packages by the Customer outside of official, verified repositories without prior approval from the Company;
- (c) Compromise, mismanagement, or improper local storage of any client-facing access tokens or application credentials by the Customer or their authorised agents.
9. Privacy and Data Protection
- The Company respects Customer privacy and will handle personal data in accordance with the UK GDPR and the Data Protection Act 2018.
- Our full Privacy Policy is available on the Company’s website.
10. WEEE Directive
- The Company complies with the Waste Electrical and Electronic Equipment (WEEE) Regulations, which require the separate collection and proper treatment of WEEE.
- Customers are encouraged to return used electrical and electronic equipment to designated collection points for recycling and proper disposal.
