Atsign unveils NoPorts for private website security

NoPorts now makes private websites invisible to attackers and accessible only through cryptographically authenticated connections.

Atsign announced a new technology, NoPorts, which changes the security approach for private websites. Traditionally, websites are exposed to potential threats due to visible entry points that can be discovered by bad actors. NoPorts eliminates this risk by making the website invisible until a user is cryptographically authenticated.

Many private websites that house sensitive information, such as those belonging to legal, healthcare, and financial institutions, often operate with open ports, allowing connections before authentication. This practice makes them vulnerable to various cyber threats, including credential stuffing and social engineering attempts.

“Current 'private' websites are fundamentally flawed. They are easily discovered by bad actors thanks to open ports and allow connections prior to authentication, enabling a variety of attacks. NoPorts flips that model by closing all inbound network ports and demanding cryptographic proof of identity before any connection, ensuring true invisibility and security,” said Barbara Tallent, CEO of Atsign.

NoPorts enhances security through:

• Invisibility - By closing open ports, NoPorts prevents unauthorized discovery and access.
• Cryptographic Identity Verification - NoPorts requires cryptographic authentication before allowing connections, thereby eliminating many risks associated with traditional password and authentication methods.
• End-to-End Encryption (E2EE) - All traffic is encrypted, ensuring data protection even if the network is compromised.

This method improves security without complicating processes for authorized users. It simplifies security management and reduces IT overhead while providing robust protection against cyber threats.

This announcement follows Atsign's development of NoPorts technology, which has already been integrated into OpenWrt devices and other platforms, showcasing its broad applicability.
