What the publisher says

NoPorts™ by atsign is the industry’s first outbound-only, identity-first connectivity solution that eliminates the need for inbound ports, VPNs, and shared tunnels. With NoPorts™, every session is an end-to-end encrypted, cryptographically authenticated handshake—driven by unique atSign identities—so services and devices remain invisible to attackers.

Deploy in minutes on any Linux, Windows, or edge device: simply install the agent, assign an atSign, and start making secure calls—whether you’re connecting developer desktops, AI inference nodes, IoT sensors, or legacy systems. NoPorts™ integrates seamlessly with atsign’s Policy Engine to enforce time-bound, context-aware controls on every connection: who, what, when, and where.

Forget static IPs, complex firewall rules, or DNS hacks. By abstracting network friction, NoPorts™ accelerates development, simplifies IT operations, and delivers true Zero Trust without compromise. Secure your infrastructure—without exposing it.

Reading the score

Disclosure · how many sources corroborate it

NoneNo source has it. Shown red, because Unknown means Unknown.
1 sourceA single place has it. A listing and its certification page and policy docs on one marketplace count as one source.
2+ contestedTwo or more sources cover it but they do not agree. The disagreement is shown, never dropped.
2+ agreeingTwo or more genuinely separate sources agree: another marketplace, or an outside record.
Steps below are possible but not automated yet, so today they sit open.
SettleTop confirmedSettleTop confirms it directly.

Evidence · what kind of evidence backs it

NoneNo source discloses it.
PublicPublicly available info, such as reviews, listing age, or vendor firmographics like legal entity and headquarters.
Vendor statedThe vendor's own claim on its marketplace listing, website, or policy documents.
Self-attestedThe vendor's self-attested certification or operator program, a marketplace program rather than an independent audit.
Steps below are possible but not automated yet, so today they sit open.
Vendor providedThe vendor hands SettleTop the underlying material, such as an SBOM or a data policy.
Vendor attestedThe vendor signs an attestation to SettleTop.
SettleTop verifiedSettleTop verifies it directly.

The SettleTop steps above are possible but not automated yet, so today they sit open and a perfect 10 is out of reach. Open information like firmographics and reach has fewer steps to climb, so it sits a little higher for the same visible evidence.

Information shown here reflects the best available information at the time of assessment and may be incomplete, outdated, or subject to change. It should be independently verified before being relied upon for any decision. SettleTop is not liable for any errors, omissions, or decisions made in reliance on this information.
