SAN JOSE, Calif., March 31, 2025 -- Atsign today announced that NoPorts™ fundamentally changes how private websites are secured. Unlike current systems where the web entry point is visible to anyone on the internet, NoPorts makes the entire website invisible until a person is cryptographically authenticated. This eliminates a significant attack vector, ensuring only authorized individuals can access the site.
Private websites, containing sensitive data for organizations like legal offices, healthcare providers, and financial institutions, typically have open ports and allow connections prior to authentication. This makes it possible for bad actors to find them by scanning for open ports and then attempt to break into them through a variety of means including credential stuffing, brute-force attacks, and social engineering methods used to bypass multi-factor authentication.
"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:
This approach strengthens security without adding complexity for authorized individuals. NoPorts simplifies security management and reduces IT overhead while providing robust protection against cyber threats.
This announcement builds upon Atsign’s ongoing development of NoPorts technology, which has already been applied to OpenWrt devices, APIs, AI models, and cloud infrastructure, demonstrating the technology’s broad applicability.
