The Vendor Who Reported Late
PayAxis processes payroll for 18,000 employees of your company, including names, bank account numbers, tax IDs, and salary. PayAxis discloses that an attacker accessed a file-transfer server 11 days before notification. The contract requires notification within 72 hours and includes a subprocessor in another country that hosts backups; the contract does not give your company audit rights and limits liability to service credits. PayAxis says the subprocessor was not affected but cannot provide logs. Your legal team asks whether to notify regulators and employees, and procurement asks whether to invoke the exit clause. The next payroll run is in five days.
1. Immediate response: how do you decide on regulatory and employee notification, and what do you demand from PayAxis?
Read the worked answer
Treat the incident as reportable until the facts prove otherwise. The decision depends on jurisdictions, data subjects, and the data elements. If any EU data subjects are involved, the 72-hour GDPR clock started when PayAxis became aware, not when it told you, and the late notification is itself a compliance problem. In the US, state breach laws may require notice for name plus bank account or tax ID, with different timing and content rules. The legal team should map employees by jurisdiction and data element before deciding, but it should not wait for PayAxis's final report to start the assessment.
Demand from PayAxis: the incident timeline, the exact files and records exposed, whether exfiltration is confirmed, the identity of the subprocessor and its role, containment evidence, and preservation of logs. The refusal to provide subprocessor logs is unacceptable; escalate to PayAxis's executive leadership and invoke the contractual notification and cooperation clauses. Ask for an independent forensic report with a scope you can review.
For employees, prepare notice language and a targeted warning about payroll-diversion phishing, because bank account data is exactly what attackers use to redirect deposits. Do not notify prematurely with wrong facts, but do not let PayAxis's delay become your delay. Document every decision and the information available at the time.
2. What contractual and relationship remediation should procurement pursue, and what leverage actually exists?
Read the worked answer
Procurement should treat the late notification and the missing subprocessor logs as material breaches of the contract, not as service-level annoyances. The first step is a formal cure notice citing the 72-hour notification clause, the cooperation obligation, and the subprocessor flow-down requirement. Demand a root-cause report, an independent forensic assessment, audit rights for this incident, and a remediation plan with dates. Service credits are likely inadequate; the company should calculate its own response costs, notification costs, and potential regulatory exposure, and reserve the right to claim those.
The leverage is uneven because payroll is live and switching in five days is not realistic. Procurement should separate the immediate continuity decision from the longer-term contract decision. In the short term, require enhanced monitoring, out-of-band verification of payroll files, and a named executive sponsor at PayAxis. In the medium term, renegotiate the contract to include audit rights, subprocessor notification and approval, data residency commitments, breach notification with defined content, liability that is not capped at service credits, and termination assistance.
If PayAxis refuses, the company should document the refusal and begin a competitive evaluation. The threat of exit is only credible if an alternative has been scoped, so procurement should start that work now even if the renewal is months away.
3. How should the company address fourth-party and subprocessor risk, including an exit plan?
Read the worked answer
The company should map the full data flow: which PayAxis systems hold employee data, which subprocessors touch it, where backups reside, and which jurisdictions are involved. The contract should require PayAxis to disclose subprocessors before onboarding, notify before changes, and give the company a right to object. For this incident, the company should require evidence that the subprocessor was not affected, not just an assertion; if logs are unavailable, that is a control gap that should be treated as a risk even if the subprocessor is innocent.
Exit planning should include data export in a usable format, deletion certification, transition assistance, and a parallel payroll run before cutover. The company should identify an alternative provider or an in-house capability and estimate the switch time. Concentration risk is the core issue: one payroll provider with a foreign backup subprocessor can create a single point of failure for pay continuity and regulatory exposure.
The CISO and procurement should report to the board that the vendor's liability cap and lack of audit rights are inconsistent with the data sensitivity. The remediation plan should be dated, funded, and tested, not just a promise to improve.
