GRC & Risk
Continuous Control Monitoring: From Annual Audits to Real-Time Assurance
Point-in-time audits tell you a control worked on the day it was tested. Continuous control monitoring tells you whether it is working now.
Key takeaways
- Tier suppliers by the data they access and the services they support.
- Match due diligence depth to tier — not every vendor needs a 300-question survey.
- Security obligations belong in the contract, with audit and notification rights.
- Monitor continuously; an annual questionnaire is a snapshot, not assurance.
Why third-party risk keeps rising
Organizations rely on hundreds of suppliers — cloud platforms, SaaS tools, outsourcers, managed service providers and niche software vendors. Many major breaches start with a supplier: stolen vendor credentials, a compromised software update or a provider with weak controls hosting your data.
The lifecycle
- Identify — maintain a single inventory of suppliers and what they do for you.
- Tier — classify by data access, system connectivity and business criticality.
- Assess — due diligence proportionate to tier.
- Contract — security, privacy, audit, notification and exit clauses.
- Monitor — continuous signals plus periodic reassessment.
- Offboard — revoke access and confirm data return or deletion.
Proportionate due diligence
| Tier | Example | Assessment |
|---|---|---|
| Critical | Core banking SaaS, MSP with admin access | Full questionnaire, evidence review, certifications, possible on-site audit |
| High | HR or CRM platform with personal data | Standard questionnaire plus SOC 2 or ISO 27001 report |
| Medium | Marketing tools with limited data | Short questionnaire, certifications check |
| Low | No data, no access | Basic onboarding checks |
Contract clauses that matter
- Minimum security controls and compliance with recognised standards such as ISO 27001 or SOC 2
- Breach notification within defined hours
- Right to audit or receive independent assurance reports
- Data location and sub-processor approval
- Return and deletion of data on exit
Continuous monitoring
Supplement periodic reviews with external security ratings, breach news, certificate expiry tracking and financial health signals. Trigger reassessment when a supplier's risk changes, not only on the anniversary.
Making it manageable
A GRC platform that sends questionnaires, scores responses, tracks evidence expiry and links supplier risks to your risk register turns TPRM from a spreadsheet exercise into a living programme. It also produces the evidence auditors and regulators expect.

Frequently asked questions
How many suppliers should we assess?
All of them should be inventoried and tiered; detailed assessment is reserved for critical and high tiers.
Is a SOC 2 report enough?
It is strong evidence, but check its scope, period, exceptions and complementary user entity controls you must operate.
Who owns third-party risk?
Typically the risk or security function sets the framework, while procurement and business owners run it day to day.
