Article summary: A vendor offboarding audit finds every one of those forgotten accounts and closes them on a set schedule instead of leaving it to chance. Businesses that run this audit regularly cut off one of the most common, least monitored paths attackers use to get in.
A freelance designer finishes a website redesign, submits the final files, gets paid, and moves on to the next client. What often gets overlooked is that they still have administrator access to the website, a login to the company's shared cloud storage, and permission to publish posts through the social media management platform.
Months or even years later, those accounts may still be active. If the freelancer's credentials are ever compromised, they can become an unexpected path into your business.
This happens more often than many businesses realize. Closing out a contract should include more than paying the final invoice. It should also include reviewing and removing every system, account, and application the vendor no longer needs. A vendor offboarding audit turns that process into a documented checklist, helping ensure former agencies, consultants, and freelancers don't retain unnecessary access long after their work is finished.
Marketing agencies and freelancers tend to accumulate more access than most businesses realize.
A single rebrand project might involve logins to the CMS, the domain registrar, the email marketing platform, a shared design folder, and two or three social accounts, often set up in a hurry with little thought about what happens when the project ends.
Employee departures usually follow a defined process, with checklists tied to a resignation, termination, or retirement. Vendor relationships often end with nothing more than a final invoice.
Third-party vendors are increasingly becoming the entry point for ransomware attacks. Black Kite's 2025 research found that ransomware was responsible for 67% of known third-party breaches, highlighting how often attackers exploit trusted business relationships instead of targeting organizations directly.
That matters because every vendor with access to your website, cloud storage, marketing platform, or other business systems becomes part of your organization's security posture. If that access is never removed after the engagement ends, it creates an unnecessary risk long after the work is finished. Recent third-party incidents have shown how a compromise at one vendor can disrupt dozens or even hundreds of customer organizations.
A vendor offboarding audit is really an inventory project first, then a cleanup project. The goal is to find every account a marketing agency, freelancer, or contractor has ever touched, not just the ones still on an active contract.
Start with accounts payable records and project files going back at least two years. Anyone who was paid for creative, marketing, or web work is a candidate for lingering access, whether or not the relationship formally ended.
Start with a complete inventory of every account the vendor can still reach. It is easy to remember the company website but overlook the shared Google Drive, email marketing platform, advertising accounts, or social media scheduling tool. A thorough review helps ensure nothing is missed.
Stale permissions inside Microsoft 365 are worth checking at the same time, since agency contacts are often added to shared mailboxes or document libraries during a campaign.
If your marketing agency or freelancer uses a shared login, make a note of it during the audit. Shared credentials cannot be tied to a specific individual, making it impossible to revoke access for one team member or accurately track who accessed your systems. Whenever possible, replace shared logins with individual named accounts.
Removing a user from a platform's dashboard does not always revoke API keys, connected apps, or webhook integrations tied to that account. Close out each one individually and confirm with a login test where possible.
A one-time audit helps eliminate existing risks, but it is only the first step. The real goal is to make vendor offboarding a standard part of every project. Just as you approve the final invoice, you should also review and remove any access the marketing agency or freelancer no longer needs.
Businesses are usually good at granting access when work begins. The same level of attention should be given to removing it when the engagement ends.
The Federal Trade Commission's small business guidance is direct about this. Limit vendor access to a need-to-know basis, and only for as long as the vendor needs it to do the job. That principle applies just as much on the way out as it does when access is first granted.
A few simple habits can keep this process running long after the initial cleanup. Whenever possible, set expiration dates when granting access to a marketing agency or freelancer so accounts do not remain active simply because no one remembered to remove them.
Add offboarding as a line item on every vendor contract, tied to a specific date rather than "when the project wraps up." And review the full vendor list on a recurring schedule, not just when someone happens to remember.
Pairing this with a vendor vetting process for new relationships covers both ends of the vendor lifecycle, so access is controlled from the first login to the last.
Most former marketing agencies and freelancers have no intention of causing harm, but forgotten accounts can still become a security risk if they are ever compromised.
A vendor offboarding audit helps ensure access is removed when the work is finished, not months or years later.

A vendor offboarding audit is a review of the accounts, logins, and permissions granted to marketing agencies, freelancers, or other contractors to confirm that access has been removed once the engagement ends.
Vendor access should be reviewed whenever a marketing agency or freelancer completes a project or the business relationship ends. In addition, an annual review helps identify any older accounts or permissions that may have been overlooked.
Marketing agencies often receive access to website hosting or the content management system (CMS), the domain registrar, social media accounts, email marketing platforms, shared cloud storage, and advertising or analytics tools. Each of these should be reviewed as part of the offboarding process to ensure unnecessary access has been removed.
