We keep websites reachable.

nsin is a connectivity-first CDN built for a network where the direct path is not always available. Point your domain at us and your site stays fast, protected and reachable — for visitors next door and for search engines on the other side of the world.

Why we built it

A site hosted in Iran is easy to reach from Iran and hard to reach from anywhere else; a site hosted abroad is the opposite. Neither is a bug in anyone's server — it is the route. Most CDNs assume that route is a solved problem and optimise the last mile. We started at the other end.

So nsin is built around reachability first: bi-directional routing between Iran and the world, an edge that keeps serving when the origin can't be reached, and certificates that stay valid through an outage. Everything else a CDN should do — caching, WAF, DDoS protection, DNS, rules, analytics — sits on top of that, and none of it asks you to change a line of code.

What we run

One platform, four things it does for you

The edge

Caching, a managed OWASP WAF, always-on DDoS protection and free auto-renewing SSL — plus cross-border routing that keeps your origin reachable in both directions.

Gateways

One-click endpoints on your own domain for the third-party APIs your app depends on: model providers, package registries, messaging and cloud platforms.

DNS & domains

Full authoritative DNS with every record type, automatic import when you move a zone in, and origin IP protection on everything you proxy.

Visibility

Live request logs, real-time analytics, uptime and outage detection, AI crawler reporting, and per-domain recommendations that tell you what to fix next.

How we work

Four things we hold to

Nothing to install
nsin works at the DNS and network layer. No SDK, no agent, no code changes — if onboarding takes longer than a coffee, we've done it wrong.
Say what actually happens
Every number in your dashboard comes from real requests at the edge, and our docs describe the product that exists rather than the one on the roadmap.
Built for this network
Panel assets load without a CDN, certificates are fetched over encrypted paths, and features are tested on the networks our customers are actually on.
Your data stays yours
We meter traffic and keep logs so you can see your own domain. We don't sell audience data, and we don't add credentials of our own to your requests.
