Portainer offers various options for connecting to Docker environments, including **Agent**, **Socket**, and **REST API Endpoints**, catering to a wide range of use cases. However, deploying Portainer in large networks where exposing management software is a security concern can be challenging. Exposing management interfaces increases the attack surface and may not comply with organizational security policies.

However, deploying Portainer in large networks where exposing management software is a security concern can be challenging. Exposing management interfaces increases the attack surface and may not comply with organizational security policies.
Peartainer addresses these challenges by leveraging peer-to-peer (P2P) networking to securely manage Docker containers without exposing any management software to the network. By using P2P connections, Peartainer ensures that communication between the client and the agent is direct, encrypted, and confined to authenticated peers, enhancing security and efficiency.

However, in large networks where security is paramount, deploying Portainer may not be the most secure option. Exposing management software or APIs can introduce vulnerabilities, and in environments where you do not want to expose any management interfaces, this becomes a critical issue. The risk of unauthorized access, interception, or exploitation increases with exposed endpoints.

By using peer-to-peer connections, users can manage Docker containers on remote hosts securely and efficiently. Peartainer is designed for environments where security and privacy are critical, such as large enterprise networks, sensitive infrastructures, or situations where network exposure must be minimized.
