Security Controls for Suppliers | 360TPRM

Security controls for suppliers define which technical and organisational minimum requirements external service providers must meet — and how their compliance is continuously monitored and demonstrated.

Categories of security controls

Security controls for suppliers fall into four categories: (1) technical controls — encryption, MFA, patch management, vulnerability management, (2) organisational controls — security policies, training, incident response processes, (3) physical controls — access control to data centres, (4) compliance controls — certifications, audits, regulatory evidence.

Making controls measurable

360TPRM measures security controls externally and automatically — without suppliers needing to complete questionnaires. Results as a measurable risk score.

Minimum requirements under regulation

NIS2 Art. 21 defines minimum requirements for all NIS2-obligated organisations and their supply chain: multi-factor authentication, encryption, patch management, incident response. DORA defines specific technical requirements for ICT third-party providers in the financial sector. ISO 27001 Annex A contains over 90 controls, several directly relevant to suppliers.

Minimum security is mandatory

Organisations that do not impose minimum security requirements on their suppliers are liable under NIS2 and DORA for damages caused by supplier failure.

Best practice: at minimum encryption of sensitive data, MFA for system access, current patch management and documented incident response processes.

Through certifications (ISO 27001, SOC 2), external scans (360TPRM), questionnaires and on-site audits for critical suppliers.
