Securing third-party remote access with Zero Trust security

63% of organizations say remote access is becoming their weakest attack surface – make sure yours is secured

According to the most recent Ponemon Institute survey, 44% of organizations experienced a third-party data breach in the last 12 months that resulted in the misuse of sensitive or confidential information.

74% said it was the result of giving too much privileged access to third parties.

Organizations are struggling to fully control and secure the access given to third parties, and it’s costing them. Many are taking solutions that are designed to provide full network access to trusted employees and trying to isolate or limit that access for third parties, or, even more risky, trusting their third parties to only access what they need. While this method may work some of the time, let’s talk about when it doesn’t work. One of your third parties, even with no malintent, could access sensitive data they aren’t supposed to and trigger a security incident or noncompliance, costing you and your organization. Or a cybercriminal could compromise one of your third parties and easily gain access to your entire network.

Unfortunately, limiting access is easier said than done – 60% of organizations aren’t able to provide third parties with just enough access to perform their assigned responsibilities and nothing more. It’s also overwhelming and a drain on internal resources to manage the permissions and access at the level good security protocol requires.

So how can companies accomplish this strict level of access without exhausting organizational resources or operating on trust? The better approach is to provide remote access that operates on the principles of zero trust network access (ZTNA). This approach begins with the assumption that individuals are a threat (rather than trusted) and are treated accordingly. Network access is provided on a least privilege basis, meaning third parties have access to only what they need, when they need it, and nothing more.

The SecureLink ZTNA solution for third parties

SecureLink’s solution provides network access based on the Zero Trust principle and provides organizations with granular controls and permissions so they can restrict third-party remote access to only the application they need and nothing else. SecureLink also stores and injects credentials so you no longer need to share usernames and passwords with third-party reps and don’t have to worry about credentials being compromised. Besides providing organizations with the tools to granularly control and isolate third-party access, SecureLink also supports all the connectivity requirements your third parties have: RDP, SSH, Telnet, VNC, as well as any TCP or UDP protocols and any native tools that the third-party vendor may have. It’s a comprehensive remote access security solution that uses a Zero Trust model to protect your network from potential data exposure.

Zero trust network access secures your third parties’ remote access connection


Zero Trust is a cybersecurity concept that focuses on restricting network access so only the right people are accessing a network for the specific information they need and nothing more. This is especially important for businesses that outsource business functions to third parties who need remote access to do their job.

How SecureLink helps organizations implement zero trust network access for their third parties

Least privilege access Provision access down to the host and port level with access timeframes and assign granular permissions to each user, ensuring individuals have only access to what they need and nothing else
Universal access methods Support connectivity and audit for all TCP and UDP protocols, including, but not limited to, RDP, SSH, Telnet, HTTP(S), FTP and custom protocols, without third parties being a node on your network
Access approvals Define required access approvals on a per-application basis, and delegate approvals to application owners
Permissions Assign granular permissions on a company or individual basis, ensuring users have the least privilege needed to perform their job
Native credential vault or integration with your PAM Store network credentials securely in the credential vault and pass directly into a session, ensuring third parties have zero visibility or access to network or application credentials
Source IP network control Define from what IPs third parties may connect from and block access from any other IP addresses
Access notifications Receive automatic notifications upon third party connection to systems, as well as a notification of disconnection and included summary of session activity
