The best third-party risk management software helps you list your suppliers, assess how risky each one is, and keep watching them after they're signed up, so a weak link in your supply chain doesn't become your breach. Startups often want vendor reviews alongside compliance work, while larger firms want questionnaires, security ratings and continuous monitoring together. Eleven tools follow in no particular order.
Your business is only as secure as the suppliers you let in. The payroll provider, the cloud host, the marketing agency with access to your customer list: each one is a door. Plenty of security incidents start with a supplier rather than the company in the headlines.
Third-party risk management, or TPRM, is how you keep track of those doors. The eleven tools below are listed alphabetically and in no particular order, from compliance platforms to dedicated TPRM suites, and every description comes from the vendor's own site, read this week. For a broader view, my tips on how to manage your supply chain better are a good place to start.

What the NCSC's twelve principles ask of you
The NCSC's supply chain security guidance proposes a series of 12 principles designed to help you establish effective control and oversight of your supply chain. They're grouped into stages, and the first stage is simply understanding the risks: knowing which suppliers you have and what they can reach.
That order matters when you pick a tool. A TPRM product that only sends questionnaires skips the hard first step. Look for one that helps you build and rank your supplier list, so the suppliers with the most access get the most attention.
Questionnaires, ratings or both?
Questionnaire-based tools send suppliers structured security and compliance questions and track the answers and evidence. Security ratings tools look at a supplier from the outside, scanning things like exposed systems and leaked credentials, and give an ongoing score.
Each has blind spots. Questionnaires rely on honest answers at one point in time; ratings can't see inside a supplier's business. Many organisations use both, sending questionnaires to key suppliers and watching ratings across the rest.
Things to check in a TPRM demo
- How do we build and rank our supplier list in the first place?
- Which questionnaires and frameworks do you support?
- Do you monitor suppliers continuously, or only at review time?
- Can suppliers reuse answers they've given elsewhere?
- How are issues tracked through to a fix?
- Can procurement, legal and security all work in the same tool?
Clues your suppliers are a blind spot
- No full supplier list exists. Teams sign up tools themselves.
- Questionnaires sit unanswered. Nobody follows up.
- Customers ask about your suppliers. You can't answer quickly.
- Reviews happen once. Nobody watches after signing.
Do you make third-party risk management software? Tool makers can ask to be considered for a featured place on this list.
My plain advice for picking a TPRM platform
List every supplier that can touch your data or systems, then rank them by how much damage a breach on their side could do. Test each tool with your top ten. If it helps you see who matters most and what to ask them, it's a better fit than one that treats every supplier the same.
Don't drown small suppliers in paperwork. Proportionate questions get honest answers; three-hundred-question forms get copied and pasted. For a quick self-check on your own house, my piece on the signs a business takes information security seriously is a useful mirror.
Frequently asked questions
What is third-party risk management?
Third-party risk management is the process of identifying, assessing and monitoring the risks that suppliers, vendors and partners bring to your business, especially security and compliance risks.
What's the difference between TPRM and vendor management?
Vendor management covers the whole supplier relationship, including contracts and performance. TPRM focuses on the risks suppliers create, such as security, privacy and resilience.
Are there free TPRM tools?
Most TPRM platforms offer demos or trials rather than free plans. Check the free plan column in the table above and each vendor's site.
What are security ratings?
Security ratings score a company's cyber risk from the outside, using data such as exposed systems and leaked credentials, and update over time.
What does the NCSC recommend for supply chain security?
The NCSC proposes 12 principles to help you establish control and oversight of your supply chain, starting with understanding the risks.
Do small businesses need TPRM software?
Small businesses can start with a supplier list and simple checks. Dedicated software helps once you have many suppliers or customers asking about your own supply chain.
