Security Manifesto & Accreditation

Speedy Tender (operated by Synthesis Tech Ltd) is engineered from the ground up to handle sensitive UK public sector and corporate bidding data. Certified under the official UK Government-backed Cyber Essentials Scheme (Certificate No: 7b75e963-4228-4c01-8dec-72df148cbe05) with active AIG Cyber Liability Cover & 24/7 Incident Response SLA, our platform enforces multi-tenant database partitioning by organisationId, zero-retention LLM integrations for Velo, mandatory MFA, and granular 5-tier RBAC.

Section 01

Architectural Foundation: Multi-Tenancy & Trust Invariants

In an enterprise bidding environment, cross-tenant data leakage is an absolute operational failure. Speedy Tender eliminates cross-contamination risks through hard logical partitioning at the database layer. Every database entity, vector embedding, and indexed Knowledge Base artifact is bound to a single verified organisationId.

Server middleware and database security rules validate the user's active session token and matching organisationId before returning any query result or permitting document parsing. Attempting to access data across organisation boundaries results in an immediate authorisation exception logged to our central security audit stream.

Domain Self-Registration & Ingress Controls

When new users register an account matching an enterprise corporate domain (e.g. @company.co.uk), they are placed into a restricted PendingApproval state by default. Self-registered users cannot view active tenders, access the Knowledge Base, or run Velo AI operations until an Organisation Admin manually elevates their authorisation state.

// Registration Enforcement Sequence
1. User registers via domain email → Account status set to PendingApproval
2. Default role assigned → Reviewer (Restricted Read-Only)
3. Access attempt to workspace → Blocked pending Admin elevation
4. Admin elevation event → Role updated & full workspace access authorised

Section 02

Five-Tier Role-Based Access Control (RBAC) Hierarchy

To provide fine-grained governance across complex bidding teams, Speedy Tender enforces a rigid 5-tier role hierarchy. Roles dictate feature access, administrative rights, Knowledge Base editing privileges, and AI operational capabilities.

1. Account OwnerRoot Sovereignty

Full administrative authority, subscription ownership, domain security management, and master organisation audit log access.

2. Organisation AdminAdministrative Control

User onboarding elevation from PendingApproval, role assignments, security policy enforcement, Knowledge Base root management, and team allocation.

3. ManagerTender Orchestration

Creation and assignment of tender projects, workflow checklist progression, task assignment, review cycle management, and submission validation.

4. WriterProposal Authoring

Active proposal co-drafting, leveraging Velo AI assistance, querying Knowledge Base evidence, drafting response sections, and updating task statuses.

5. FREE Reviewer (Guest Seat)FREE Auditor Seat

Complimentary read-only access for internal executives, legal advisors, external compliance auditors, and subject matter reviewers. Reviewers can inspect proposals, add comments, and approve compliance checks, but are strictly prohibited from mutating core tender documents or triggering automated AI operations.


Section 03

Operational Safeguards & Velo Role Controls

To preserve document integrity and enforce strict operational boundaries, Speedy Tender applies granular role-based guardrails around high-grade analytical services. Execution of Velo AI generation, deep vector indexing, automated specification parsing, and compliance gap analysis is restricted to active writing and management seats.

Guest Reviewers maintain read-only access to inspect proposals and review compliance checks without permission to mutate workspace data or initiate automated AI co-drafting routines.

Enforced Reviewer Authorisation Response

When a user in a Reviewer seat attempts to execute a Velo AI generation, document parsing sequence, or automated gap analysis, the backend server middleware immediately intercepts the request and aborts execution before invoking AI services:

// Standard Authorisation Exception Response
"Access Denied: Your Reviewer role does not allow cost-generating operations (such as analysis by Velo)."

Section 04

Data Sovereignty & Model Training Opt-Outs

Public sector tenders often contain sensitive UK sovereign data, defence specifications, and confidential healthcare protocols. Speedy Tender operates under strict UK data residency and privacy invariants:

UK (London) Data Residency

All primary Firestore databases, vector indices, document stores, and application servers are hosted exclusively within Google Cloud UK (London) data centres (europe-west2), ensuring complete compliance with UK GDPR and Crown Commercial Service guidelines.

100% LLM Training Opt-Outs

All Velo AI co-drafting interactions utilise enterprise-tier API agreements with 100% data retention opt-outs. Your proprietary tender responses, Knowledge Base evidence, and organisational IP are never stored by AI providers or used to train public foundation models.

Mandatory Multi-Factor Authentication

Multi-Factor Authentication (MFA) is strictly enforced across all user accounts without exception, ensuring robust identity verification and protecting workspace ingress against unauthorised access.

12-Hour Session TTLs & Encryption

User session tokens enforce a mandatory 12-hour expiration time-to-live (TTL). All data at rest is encrypted using AES-256 standards, while data in transit is secured via TLS 1.3 encryption.


Section 05

Cyber Essentials Accreditation & AIG Cyber Risk Indemnity

To provide ultimate transparency for UK public sector bodies, NHS trusts, and enterprise bidding departments, Synthesis Tech Ltd (operator of Speedy Tender) has achieved official Cyber Essentials Certification under the UK National Cyber Security Centre (NCSC) framework.

The 5 Core Cyber Essentials Safeguards Implemented

1. Firewalls & Gateway Protection

All network boundaries are protected by hardware and cloud security rules, isolating application clusters and preventing unauthorized ingress.

2. Secure System Configuration

Servers and cloud components operate under strict infrastructure-as-code baseline configurations, disabling unused ports and default guest accounts.

3. User Access & Mandatory MFA

Access to admin functions and user accounts requires mandatory Multi-Factor Authentication (MFA) and 5-tier role-based access restrictions.

4. Malware & Threat Protection

Continuous endpoint protection, automated file payload scanning, and browser sandboxing prevent malicious code execution.

AIG Cyber Liability Cover & 24/7 First Response Incident SLA

Policy Number: 0038323276 • Master Policy: 38181000

To complement our Cyber Essentials technical perimeter, Synthesis Tech Ltd maintains active Cyber Liability Cover underwritten by American International Group UK Limited (AIG / Policy No. 0038323276).

Rather than relying on passive protection, this cover integrates a mandatory 1-hour SLA with AIG’s First Response Service (+44 (0)1273 730992). In the event of a suspected incident, dedicated IT forensics specialists (Grant Thornton) and legal counsel (CMS Cameron McKenna) deploy immediately to contain threats, restore systems, and ensure operational continuity for our enterprise client workspaces.
