Vendor Privacy Monitoring Program

Overview

GDPR Article 28(1) imposes a continuing obligation on controllers to ensure that processors maintain sufficient guarantees. This is not a one-time assessment — the EDPB Guidelines 07/2020 (paragraph 87) explicitly state that the controller's assessment obligation is ongoing. The Vendor Privacy Monitoring Program at Summit Cloud Partners implements continuous oversight proportionate to the risk each vendor presents.

Monitoring Framework

Tier-Based Monitoring Schedule

Activity	Tier 1 (High Risk)	Tier 2 (Standard)	Tier 3 (Low Risk)
Full reassessment	Annual	Biennial	Triennial
Privacy audit	Annual (Type 2/3)	Annual (Type 1)	Biennial (Type 1)
Sub-processor list verification	Quarterly	Semi-annual	Annual
DPA compliance review	Annual	Biennial	Triennial
Risk score recalculation	Semi-annual	Annual	Biennial
Certification status check	Quarterly	Semi-annual	Annual
Breach monitoring	Continuous	Continuous	Monthly check
Contract renewal privacy gate	120 days before	90 days before	90 days before

Continuous Monitoring Signals

Automated or semi-automated monitoring sources that provide ongoing visibility:

Signal Source	What It Monitors	Frequency	Alert Trigger
Vendor risk intelligence platform	Public breach disclosures, enforcement actions, news	Daily	New incident involving a monitored vendor
Certification monitoring	ISO/SOC certificate validity and scope changes	Monthly	Certificate approaching expiry (60 days)
CASB/DLP	Data flows to vendor — volume and category anomalies	Continuous	Data transfer exceeding baseline by 200%
DNS/network monitoring	Connectivity patterns to vendor endpoints	Continuous	New endpoints, geographic changes
Vendor security scorecard	External security posture assessment	Monthly	Score drops below threshold
Regulatory database monitoring	New enforcement decisions involving vendor	Weekly	New published enforcement action
Sub-processor registry monitoring	Vendor-published sub-processor list changes	Weekly	New or changed sub-processor detected

Annual Reassessment Process

For each vendor due for reassessment:

Phase 1: Preparation (30 days before reassessment)

Activity	Responsible
Pull current vendor profile and risk score	Privacy Team
Review monitoring signals from prior period	Privacy Team
Compile open audit findings and remediation status	Privacy Team
Identify changes since last assessment	Privacy Team
Send reassessment questionnaire to vendor	Privacy Team

Phase 2: Assessment (Assessment month)

Activity	Responsible
Review vendor's updated questionnaire responses	Privacy Team
Verify current certifications	Privacy Team
Review sub-processor list for changes	Privacy Team
Assess any processing scope changes	Privacy Team
Conduct audit (per tier schedule)	Audit Team
Recalculate risk score	Privacy Team

Phase 3: Decision and Documentation

Activity	Responsible
Update sufficiency determination	DPO
Update vendor risk tier (if changed)	Privacy Team Lead
Update monitoring schedule	Privacy Team
Communicate outcomes to business unit	Privacy Team
File reassessment documentation	Privacy Team

Contract Renewal Privacy Gate

When a vendor contract approaches renewal, a privacy gate ensures continued compliance:

Timing	Activity
120 days before renewal (Tier 1) / 90 days (Tier 2/3)	Privacy Team notified of upcoming renewal
90 days before renewal	Review current privacy compliance status
60 days before renewal	Complete any required reassessment
30 days before renewal	Issue renewal privacy recommendation (Renew / Renew with conditions / Do not renew)
At renewal	Execute any required DPA amendments

Renewal Privacy Decision Matrix:

Compliance Status	Audit Status	Risk Trend	Recommendation
Fully compliant	Clean audit	Stable/improving	Renew
Minor gaps	Minor findings only	Stable	Renew with conditions
Material gaps	Major findings pending	Deteriorating	Renew with conditions + accelerated audit
Significant non-compliance	Critical findings open	Deteriorating	Do not renew (initiate termination planning)
