Vendor contracts include minimum cybersecurity requirements
A vendor security questionnaire is useful, but without contractual obligations there is no legal basis to require a vendor to improve, notify you of a breach, or accept liability. Contracts are where accountability lives. Minimum cybersecurity requirements in vendor contracts create enforceable obligations for breach notification, data handling, subprocessor management, and the right to audit. They also signal to vendors that you take security seriously.
Implementation steps
- 1
Develop a standard security addendum for vendor contracts
Work with legal to create a vendor security addendum that covers: breach notification timelines (typically 72 hours), data handling and encryption requirements, restrictions on sharing data with subprocessors without notice, the right to request audit evidence such as SOC 2 reports, and the vendor's obligation to maintain a security program. Apply this addendum to all new contracts and renewals with high-risk vendors.

Negotiate security requirements into existing high-risk vendor contracts
For vendors already under contract who have high-risk access to your environment, seek to add a security addendum at the next renewal or via contract amendment. Prioritize vendors with access to sensitive data or production systems. Keep a log of which vendors have security requirements in their contracts and which do not, along with planned remediation dates.

Track breach notifications and enforce contractual obligations
When a vendor notifies you of a breach, verify the notification timeline against your contract. Document the incident, assess your exposure, and take action as appropriate. If a vendor fails to meet contractual security obligations, engage your legal team. Track all vendor security incidents and their resolution in your incident log.
