60% of cyber attacks now come from the supply chain
SolarWinds, Kaseya, MOVEit — the common denominator of these breaches, which affected companies globally, was supply chain vulnerabilities. Not directly over a strong target for attackers, but through a weaker supplier It is much easier to pass.
Regulatory pressure is also increasing rapidly in Turkey: ISO 27001:2022, KVKK, BDDK, DORA and DDO BIGR regulations now require TPRM. legal and institutional obligation made it into
- Invisible third party accessDo you know with what permissions and from which devices supplier personnel access your systems?
- Uncontrolled personal data sharingAre the personal and commercial data you transfer to your suppliers protected by adequate technical measures within the scope of KVKK?
- ISO 27001 audit findingsSupplier control evidence has now become a priority area of examination in surveillance audits.
- Incomplete contractual obligationsYour contracts do not clearly address security requirements, right to audit, and breach notification obligations.
- Fourth party (N+1) risksYour suppliers' suppliers are also part of your risk surface. Without monitoring this layer, the program is incomplete.

What Is TPRM? Core Concepts and Scope
TPRM (Third Party Risk Management)It is the discipline of managing an organization's information security, operational, legal and reputation risks arising from third parties such as suppliers, business partners, software developers, cloud providers and external service companies within a structured framework.
What Risks Does TPRM Cover?
Cybersecurity Risk
Vulnerabilities that can be used to infiltrate the organization through supplier systems, inadequate access control and insecure software development practices. Supplier VPN access, API integrations and shared platforms are the main carriers of this risk.
Data Privacy Risk
Whether the personal or commercial data transferred to the supplier is processed lawfully within the scope of KVKK/GDPR. It must be documented by the institution whether the supplier, as a data processor, has taken adequate technical and administrative measures.
Operational Continuity Riski
Impact on business continuity in the event of a critical supplier outage. Alternative supplier plan, SLA assurance and exit strategy are the key elements of managing this risk.
Compliance and Reputation Risk
Regulatory consequences and reputational damage that the organization will suffer due to the supplier's inclusion on sanctions lists, license violations or ethical violations.
5 Essential Elements of an Effective TPRM Program
1. Making the Supplier Portfolio Visible
Many organizations do not even have an accurate list of all active suppliers. “Shadow vendors” — SaaS tools and services connected without IT approval — frequently emerge at this stage.
2. Risk-Based Prioritization
Suppliers; They are classified on the basis of data sensitivity, level of connection to systems and impact on business continuity. Critical suppliers are handled with on-site inspection, and standard suppliers are handled with survey evaluation.
3. Control-Based Evaluation
Structured questionnaires based on ISO 27001, NIST CSF or CIS Controls references are used. Certificates are not considered statements; It is confirmed through an independent verification process.
4. Contract and Legal Basis
It is critical to include security requirements in supplier contracts. The right to audit, breach notification periods, data deletion obligations and business continuity conditions should be clearly stated.
5. Continuous Monitoring and Living Program
Program; It should be constantly kept alive through an annual re-evaluation cycle, incident reporting mechanism and new supplier onboarding process.

Results talking
Secure Fors managed our audit process within our supplier ecosystem in a completely professional manner. The findings led to immediate action by both our technical team and senior management.
Supplier control evidence was the most questioned area in our ISO 27001 surveillance audit. The TPRM documentation prepared by Secure Fors fully satisfied the auditors, and we came out with zero non-compliance.
wondered questions
A supplier audit is a one-time assessment of a specific supplier. TPRM is a management program that covers the entire supplier portfolio and includes repeatable and continuous monitoring. Audit is one step of the program; The program is a much broader framework.
If you have more than 5 vendors accessing your data or systems and are subject to any regulatory standards, it makes sense to set up a TPRM program. Even in small portfolios, contract security is critical.
Yes, supplier cooperation is mandatory for on-site inspection. For this reason, we recommend that the right to audit be added to supplier contracts from the beginning. In cases where cooperation cannot be achieved, an alternative evaluation can be carried out with remote evaluation and evidence verification.
Yes. Your ISO 27001 certification covers your organization's own ISMS; It does not guarantee the security maturity of your suppliers. ISO 27001:2022 Clause A.5.19–A.5.22 controls require separate evidence for supplier relationships.
Our reports are prepared in a standard structure, including methodology, evidence and findings sections. Evaluations prepared by our expert team may serve as evidence in legal processes; We recommend that you verify your specific needs with your attorney.
ISO 27001:2022 Annex A controls are our main reference. Depending on the sector, NIST SP 800-161, CIS Controls v8, DORA ICT risk requirements and DDO BIGR criteria are integrated into the evaluation.
