Secure vendor remote access starts with a simple principle: give each IT contractor access only to the systems and information needed for the specific task. A vendor may need to troubleshoot a workstation, manage a server, or update a business application. Those tasks do not automatically require access to every account, device, or file.
A clear process helps your team support outside work without relying on shared passwords or leaving access active indefinitely. Before granting access, confirm the request, define its scope, use an individual account with safeguards, and decide when access will end.
Start by verifying the request
Before approving access, confirm that the request is legitimate and that the person asking is authorized to do the work. An email that appears to come from a familiar vendor is not, by itself, proof that the request is genuine. If a message asks for credentials, broad access, or an urgent change, pause and verify it through a known contact method, such as a previously established phone number or vendor portal.
Then write down the work the vendor needs to complete. Identify the systems involved, the type of access required, and the person responsible for approving it. This keeps an access request tied to a business task rather than an open-ended request for general access.
The CISA guidance for managed service provider customers is a useful reference for considering vendor relationships and access-related risks.
Give each vendor employee a separate account
Use a named account for each person who needs access instead of sharing a general vendor login. Individual accounts make it easier to know who connected, change one person’s permissions, and remove access when that person no longer needs it. Shared credentials make those actions harder and can leave uncertainty about who performed a particular action.
Ask your IT contact to create an account specifically for the vendor’s work. Avoid reusing an employee’s account or handing over an employee’s password. Keep vendor credentials separate from routine business email and other accounts, and make sure the account owner and purpose are documented.

Apply least privilege to the task
Least privilege means giving an account the minimum access needed to complete its approved work. If a contractor is troubleshooting a particular application, restrict access to that application where possible. If the task concerns one server or group of devices, avoid granting access across the full network unless the work genuinely requires it.
Administrator permissions may be necessary for certain maintenance or configuration tasks, but they should not be the default for routine support. Ask what elevated access is needed, why it is needed, and whether it can be limited to the task or time when it is required. If broader access is unavoidable, agree on who will approve it and how it will be reviewed afterward.
A VPN or remote access tool can provide a connection, but the connection alone does not determine what the vendor can reach. Configure permissions and network access to match the approved scope. CISA’s guide to securing remote access software provides additional security considerations for these tools.
Require MFA and secure the connection
Require multifactor authentication (MFA) for vendor accounts that access business systems remotely. MFA adds a verification step beyond a password and helps protect an account if a password is exposed. Use MFA wherever the system and access method support it, including remote access tools and administrative accounts.
Also agree on the remote access method before work begins. Use a solution approved by your business, keep it configured for the intended systems, and avoid leaving unattended sessions open. Ask the vendor to use a properly secured device and to tell you if the device or account may have been exposed. These details belong in your access process, not just in an informal email exchange.
MFA is an important safeguard, but it does not replace careful account permissions or monitoring. Zevonix’s guide to what to check when an account is compromised despite MFA explains why layered controls still matter.
Set an end point and review activity
Temporary vendor access should have a clear end point. When approving the request, record when access should expire or who will confirm that the work is complete. If the timing changes, review the need and approve an extension rather than leaving access open by default.
During and after the work, review available sign-in and activity logs. Check that access happened through the expected account and method, and that activity fits the approved task. For sensitive changes, have an internal owner confirm the result. Keep records of the approval, the systems involved, and the access removal so your team has a reliable account of the work.
When the work is finished, disable or remove the vendor account, end active sessions where the system allows, and revoke any related remote access permissions that are no longer needed. Zevonix’s technology access removal checklist can help inform a consistent process for closing access.
Agree on security expectations before work starts
For ongoing vendor relationships, document access expectations in your service agreement or another written process. The details should fit the work and the systems involved. Consider covering:
- Which named vendor employees may access your systems and how their identity is verified.
- Which systems, data, and actions are in scope, including how elevated permissions are approved.
- The approved remote access method, MFA expectations, and device security responsibilities.
- Whether subcontractors may be involved and how their access is approved and controlled.
- How access activity is recorded and reviewed, and who your business can contact with questions.
- How quickly the vendor should notify you about a suspected account or device exposure.
- When access expires and how accounts, permissions, and active sessions are removed.

Frequently asked questions
Should IT contractors have their own user accounts?
Yes. Use a separate, named account for each contractor who needs access. Avoid shared logins so activity and permissions can be tied to the individual.
Should vendors use MFA for remote access?
Yes, require MFA for vendor access where it is supported. Pair it with scoped permissions, secure access tools, and activity review.
Is it safe to give an IT vendor administrator access?
Only when the task requires it. Ask why elevated permissions are needed, limit them to the relevant systems and work, and remove them when the task is done.
How long should a contractor keep remote access?
Keep access only as long as the approved work requires. Set an end point when access is granted, review any extension, and disable access after the work is complete.
Make vendor access deliberate
Secure vendor remote access is easier to manage when each request has a verified purpose, a named account, limited permissions, MFA, activity review, and a defined end point.
