A campaign can take weeks of planning, several rounds of approvals and a team of people working across different locations. Yet all it takes is one shared password, a misplaced file or an account that was never closed after a freelancer left to create a problem.
Creative agencies handle a mix of information that clients would rather keep private. There are advertising accounts with access to live budgets, social media profiles, unreleased campaign ideas, product launches and presentations that have not yet been approved. Keeping this material safe is part of managing the client relationship, even when nobody on the team has a formal IT role.
The weak points are often found in everyday working habits rather than sophisticated attacks.

When Everyone Uses the Same Login
Sharing a password can seem harmless when a small team is trying to get a campaign out on time. The trouble starts when somebody changes roles, leaves the agency or needs to be removed from a project.
With a shared login, it may be difficult to know who made a change. Resetting the password can also leave the rest of the team locked out until everyone receives the new credentials.
Where platforms allow it, each team member should have their own account and only the permissions they need. A designer working on campaign assets rarely needs the same access as someone managing advertising spend. Keeping those responsibilities separate makes mistakes easier to trace and access easier to withdraw.
A password manager can help teams avoid reused passwords and share credentials securely when individual accounts are not available. Two-factor authentication adds another layer of protection if a password is stolen.
Remote Work Needs More Than a Secure Wi-Fi Connection
Agency work does not always happen at a desk in the office. A strategist might review a campaign from an airport lounge, while an account manager checks an advertising dashboard from a hotel.
Public Wi-Fi is not automatically unsafe, but unfamiliar networks and fake hotspots can expose users to risks. Staff should verify network names, avoid suspicious login pages and keep their devices and applications updated.
A business VPN can encrypt traffic between a device and the VPN server, helping protect data as it travels across a network. It is one option for agencies whose teams regularly work remotely, although it cannot prevent phishing, malware or unauthorised access caused by stolen credentials.
The bigger question is whether the agency has clear rules for accessing client systems outside the office. Employees should know which devices and tools they can use, how to report suspicious activity and whom to contact if an account behaves unexpectedly.
The Problem With Unreleased Campaign Files
A draft advertisement sent to the wrong person can cause an awkward conversation. An unreleased product film or confidential pitch deck reaching the public can create a much bigger problem for the client.
Email attachments and open sharing links are easy to use, which is why they can become the default for moving files between teams. But once a file has been downloaded or a link has been forwarded, controlling its distribution becomes harder.
Agencies should keep working files in approved project spaces and give access only to people who need it. Where available, sign-in requirements and expiry dates can help limit who can open shared links. Sensitive files should not sit indefinitely in personal drives or folders that everyone in the agency can access.
It also helps to agree on a single location for approved artwork and final deliverables. This reduces the chance of a client receiving an outdated version or a team member accidentally sharing material that was never cleared for release.
Freelancers Need an Exit Plan Too
Freelancers and specialist production teams are part of normal agency life. They may need access to a client’s social account, a shared folder or a project management tool for only a few weeks.
That access should have an end date. When a project wraps up, someone should check which accounts, folders and platforms were shared and remove permissions that are no longer required. The same review should happen when an employee leaves or moves to another account.
This is easy to overlook during a busy handover, especially when several campaigns are running at once. A simple offboarding checklist makes it a routine task rather than something the team remembers only when a problem arises.
Have a Plan for When Something Goes Wrong
Even careful teams make mistakes. Someone may send a file to the wrong recipient, lose a laptop or discover an unfamiliar login to a client account.
The first response matters. Agencies should know who can secure the affected account, revoke access, contact the relevant platform and assess what information may have been exposed. They should also know who is responsible for informing the client when necessary.
Backups are worth checking before they are needed. Keeping protected copies of important project files separately from the main working environment can help an agency recover from accidental deletion, hardware failure or ransomware. A backup that has never been tested is not much reassurance.
Client Trust Is Part of the Job
Clients may never ask how an agency manages permissions or stores its working files. That does not make those details unimportant. When a team is entrusted with an advertising account or a campaign that has not yet launched, the responsibility extends beyond producing good creative work.
The practical steps are straightforward: stop relying on shared logins, review access when projects end, control how files are distributed and make sure everyone knows what to do when something goes wrong.
These habits will not eliminate every security risk, but they can prevent avoidable mistakes and make it easier to respond when problems occur. For an agency, that is part of looking after the work and the relationship behind it.
