Corporate VPN

Corporate VPN Setup: Site-to-Site & Remote Access

Link your offices, branches and properties into one private network, and give staff secure access to office systems from anywhere - on WireGuard and IPsec, set up and managed by iberry.

Two kinds of business VPN

Site-to-site VPN

A permanent encrypted tunnel between the routers of two or more sites. The head office, branches, warehouses or hotels share one private network: files, cameras, the accounts server and printers reachable between them, with nothing exposed to the internet. It replaces a leased line or MPLS link for most small and mid-sized businesses.

Remote access VPN

Staff laptops and phones connect to the office from home, a hotel or a client's site, and reach the file server, Tally, ERP or remote desktop as if they were at their desk. Each person gets their own key, which can be revoked the day they leave.

What iberry sets up

⚡

WireGuard

Modern, fast and simple to keep running. Clients for Windows, macOS, iOS, Android and Linux. Our default for both site-to-site and remote access.

🔗

IPsec (IKEv2)

Where the other end needs it - another vendor's firewall, a partner's network or a cloud provider's VPN gateway.

🔀

Split or full tunnel

Only office traffic over the VPN, or everything, per person - whichever your policy needs.

🚪

Access per person

Accounts can reach only what they need: the accounts team to the accounts server, the camera vendor to the cameras.

🔄

Survives line failures

On sites with two internet lines, tunnels move to the surviving line automatically. See internet failover.

📓

Records

Who connected, when and from where, kept and available to you.

Why not just open a port?

Opening a port on the router so staff can reach remote desktop, the camera recorder or the accounting server is the most common way small businesses get broken into: the service is visible to everyone on the internet, all the time. A VPN keeps those services invisible from outside. Only devices holding a valid key can reach them at all.

Already have a VPN that keeps disconnecting?

Office VPNs that drop or will not connect usually come down to a few causes: the office line changing its public address, a second internet line taking over without the tunnel following, an ISP router in front of the firewall blocking the VPN port, or an old protocol that phones no longer support. We find which one it is, fix it, and move you to WireGuard if that is the cleaner answer. MikroTik routers already in place can usually be kept - see MikroTik services.

Frequently asked questions

What is the difference between site-to-site and remote access VPN?

Site-to-site VPN joins whole networks - two offices - permanently, router to router. Remote access VPN connects one person's laptop or phone to the office when they need it. Most businesses with a branch and remote staff use both.

Is WireGuard secure enough for business use?

Yes. WireGuard uses modern cryptography, has a small, heavily reviewed code base and is built into Linux and supported by major router platforms, including MikroTik RouterOS. Each user and site has its own key.

Can staff use the VPN on their phones?

Yes. The official WireGuard app runs on iOS and Android as well as Windows, macOS and Linux. We send each person a configuration, often as a QR code to scan.

Can a VPN replace our leased line between offices?

For most small and mid-sized businesses, yes: two ordinary internet connections and a site-to-site VPN cost far less than a leased line or MPLS link, and with a second line at each end they keep running when one provider fails.

Can you set up a VPN between offices in different countries?

Yes. The tunnels run over the internet, so the distance does not matter. We configure both ends remotely; a local partner installs hardware where needed.

What does a corporate VPN cost?

Site-to-site and remote access VPN are set up on iberry's firewall plans (from ₹30,000 one-time in India, ₹15,000 yearly maintenance). Projects with several sites or outside India are quoted individually.

Need offices linked or staff connected?

Tell us how many sites, how many remote users and which systems they need to reach. Published firewall plans in India are ₹30,000, ₹50,000 and ₹99,000 one-time, each with ₹15,000 yearly maintenance; DNS Hosted Security is ₹9,000 a year. Outside India every project is quoted on its own. The MikroTik hardware is usually supplied through a local vendor in your country, so there is no import; it can also be shipped from India.
