Third-Party Management Policy

Policy Owner: Jarvis (Hai) Luony

Effective Date: 21.01.2025

Purpose

To ensure protection of the organization's data and assets that are shared with, accessible to, or managed by suppliers, including external parties or third-party organizations such as service providers, vendors, and customers, and to maintain an agreed level of information security and service delivery in line with supplier agreements.

This document outlines a baseline of security controls that Tekai expects partners and other third-party companies to meet when interacting with Tekai Confidential data.

Scope

All data and information systems owned or used by Tekai that are business critical and/or process, store, or transmit Confidential data. This policy applies to all employees of Tekai and to all external parties, including but not limited to Tekai consultants, contractors, business partners, vendors, suppliers, partners, outsourced service providers, and other third-party entities with access to Tekai data, systems, networks, or system resources.

Policy

Information security requirements for mitigating the risks associated with supplier's access to the organization's assets shall be agreed with the supplier and documented.

For all service providers who may access Tekai Confidential data, systems, or networks, proper due diligence shall be performed prior to provisioning access or engaging in processing activities. Information shall be maintained regarding which regulatory or certification requirements are managed by or impacted by each service provider, and which are managed by Tekai as required. Applicable regulatory or certification requirements may include ISO 27001, SOC 2, PCI DSS, CCPA, GDPR or other frameworks, compliance standards, or regulations.

Information Security in Third-Party Relationships Addressing Security in Agreements

Relevant information security requirements shall be established and agreed upon with each supplier that may access, process, store, transmit, or impact the security of Confidential data and systems, or provide physical or virtual IT infrastructure components for Tekai.

For all service providers who may access Tekai production systems, or who may impact the security of the Tekai production environment, written agreements shall be maintained that include the service provider's acknowledgment of their responsibilities for the confidentiality of company and customer data, and any commitments regarding the integrity, availability, and/or privacy controls that they manage in order to meet the standards and requirements that Tekai has established in accordance with Tekai's information security program or any relevant framework.

Technology Supply Chain

Tekai will consider and assess risk associated with suppliers and the technology supply chain. Where warranted, agreements with suppliers shall include requirements to address the relevant information security risks associated with information and communications technology services and the product supply chain.

Third-Party Service Delivery Management Monitoring & Review of Third-Party Services

Tekai shall regularly monitor, review, and audit supplier service delivery. Supplier security and service delivery performance shall be reviewed at least annually.

Management of Changes to Third-Party Services

Changes to the provision of services by suppliers, including changes to agreements, services, technology, policies, procedures, or controls, shall be managed, taking account of the criticality of the business information, systems, and processes involved. Tekai shall assess the risk of any material changes made by suppliers and make appropriate modifications to agreements and services accordingly.

Third-Party Risk Management

Tekai will ensure that potential risks posed by sharing Confidential data or providing access to company systems are identified, documented and addressed according to this policy. Risk management plays an integral part in the governance and management of the organization at a strategic and operational level. The purpose of a partner and third-party security policy is to ensure that partnerships and services achieve their business plan aims and objectives, and are consistent with Tekai's requirements for information security.

Tekai shall not share or transmit Confidential data to a third-party without first performing a third-party risk assessment and fully executing a written contract, statement of work or service agreement which describes expected service levels and any specific information security requirements.
