Any time you open your network to external resources, you incur additional risks. However, if you use a trusted extranet solution, the connection to your server should be highly secure and you will have complete control over who can utilize that external connection. Provided you select an extranet resource that meets or exceeds your company’s data security standards, properly vet employees and partners with access to your extranet, and effectively manage their rights and permissions, your extranet should not pose a significant threat.
