What nsin does for your site
Faster.
Your files are served from the edge, close to each visitor, and your server does far less work.

- One-click purge, whole site or one URL
- Image, JS and CSS optimisation
Safer.
Attacks are stopped before they reach your server, and your server address stays hidden.
- Managed OWASP firewall
- Always-on DDoS protection
- Rate limits, challenges and bot rules
Always online.
Visitors and search engines keep reaching your site, in Iran and abroad, even when your server is down.
- Cached pages served when your server is down
- Routing between Iran and the world, both ways
- Googlebot keeps crawling
Live in three steps
No code changes, nothing to install, and your site keeps loading while you switch.
- 01
Add your domain
Create your domain in the panel. nsin scans your current nameservers and imports your existing DNS records automatically.
- 02
Point your DNS
Switch to nsin's nameservers and flip records to proxied. Free SSL is issued and renewed automatically — nothing to install.
- 03
Tune & watch
Set cache rules, security and rate limits per path, then watch live traffic, cache hit-rate and visitor geography in real time.
Only on nsin.
Every CDN caches and protects. These are the things you get here and not on other Iranian CDNs.

|---|---|---|
info@your-domain, delivered to the inbox you already use. On every plan, Free too. | No | Yes |
nsin sees your server stop answering and tells you by SMS and email. | No | Yes |
Bot Cache Search engines get every page from an edge copy, so Googlebot always gets a fast answer. | No | Yes |
AI agents get clean Markdown instead of HTML, typically 5–10× fewer tokens. | No | Yes |
See every AI crawler by name, and allow, block or reroute each one. | No | Yes |
OpenAI, Anthropic, npm and more on a hostname under your own domain. | No | Yes |
Visitors and Googlebot abroad keep reaching a site hosted in Iran. | No | Yes |
Your own traffic turned into a checklist of what to fix next. | No | Yes |

Numberland, CEO“The fundamental problem we always had — and it got far worse during the internet blockade — was keeping a stable link between our servers inside Iran and the ones outside, in both directions. nsin solved it completely, and it was an enormous help to us.”
“We have both foreign and Iranian users, and nsin has solved the service-stability headaches for both. On top of that, since our server is abroad, it removed our worry about internet blackouts too.”
Paziresh24, DevOps“One of our constant challenges at Paziresh24 was reliable access to the platform for users outside the country — something that had gone a long time without a clear answer. nsin fixed it, and users abroad can now use the platform with no trouble.”
Fartak Cloud, Founder“One of the main challenges nsin solved for us was giving us a single platform for logging requests, without having to build any infrastructure of our own for it.”
Pricing
Each domain has its own plan; your wallet is shared across domains. Pay-as-you-go traffic on top. Get started free in the panel.
Every new domain starts on the Free plan, which renews automatically at no cost — get your site online first, then upgrade whenever you need more.

Questions.
What is a CDN and why do I need one?
A Content Delivery Network caches your site at edge locations close to visitors, so pages load faster and your origin handles far less load. nsin adds security and always-on reachability on top.
Do I need to change my code?
No. nsin works at the DNS and network layer. You point your domain at nsin — no SDK, no agent, no code changes.
Is SSL included?
Yes. Free certificates (including wildcards) are issued and renewed automatically and served from the edge — even if your origin is temporarily down. You can also upload your own.
How much does it cost?
Every new domain starts on the Free plan, which renews automatically at no cost. Upgrade any time to a per-domain plan with pay-as-you-go bandwidth, where cached traffic is billed at the lowest rate.
