[ SECURITY AND CONNECTIONS ]

Why business needs its own private VPN network

Mitigating traffic interception threats, protecting against RDP breaches, and unifying the team into a single framework

[ 01 ]

Closure of vulnerable RDP ports and external databases

Publicly open remote desktop port is the main target for hackers and encryptors. Through VPN your servers become invisible to internet scanners.

[ 02 ]

Quick joint work with files between cities

A warehouse employee in Lviv or an office employee in Kyiv opens documents on a shared server as if he were sitting next to the wall in one local network.

[ 03 ]

Safe work of employees with public Wi-Fi networks

Employees in cafes, hotels or trains connect through an encrypted corporate tunnel, preventing interception of login and passwords by malicious actors.

[ 04 ]

Immediate blocking of access for freed employees

Centralized certificate management allows to revoke the access key of a former employee within 30 seconds, instantly cutting off access to all databases.

[ Engineering Standard of Connection ]

What is included in building a corporate VPN backbone

Creating a reliable encrypted infrastructure with guaranteed throughput

[ STEP 01 ] Design

Pre-project audit of channels and selection of cryptographic protocols

We evaluate the speed of internet channels at locations, select a protocol: ultra-fast WireGuard, industrial IPsec IKEv2 or universal OpenVPN.

[ STEP 02 ] VPN Gateway

Deployment of dedicated VPN gateway (Hardware / Cloud)

We configure the router MikroTik, Cisco or virtual server in a secure data center in Germany as the central network hub.

[ STEP 03 ] Site-to-Site

Construction of Site-to-Site Tunnels Between Branches

We are combining the central office, warehouses, stores and production into a single local network with a common address and static routes.

[ STEP 04 ] Remote Access

Configuration of client access (Road Warrior VPN)

We create personalized configurations for employees' computers and smartphones (Windows, macOS, Linux, iOS, Android).

[ STEP 05 ] 2FA Protection

Integration of two-factor authentication (2FA / MFA)

Connecting confirmation of login through one-time codes from Google Authenticator, Telegram or hardware security keys.

[ STEP 06 ] Testing & Handover

Stress tests for encryption speed and key transmission

Measuring the real throughput of channels under load (iperf3), transmitting documentation and backup copies of keys.

[ FREQUENT QUESTIONS ]

Answers to common questions from customers

Key details regarding terms, independent website editing, and rights transfer.

WireGuard has an extremely compact code base (about 4 000 lines of code compared to hundreds of thousands in OpenVPN), making its vulnerabilities practically impossible. It uses the latest ChaCha20/Poly1305 cryptography, provides transmission speeds up to 1 Gbit/s even on weak routers and practically instantly restores the connection when the network changes (for example, when switching from Wi-Fi to 4G).

With proper hardware configuration — practically unnoticed. Speed drop is no more than 3–5%, since modern processors on routers and servers have built-in hardware acceleration AES-NI, which encrypts traffic on the fly without delays.

Yes, this is exactly the main goal of building a Site-to-Site VPN. All connected offices work in a single address space: employees at the warehouse can directly access the main office server by its internal IP address, without having to open the server to the public internet.

This is not a problem. We configure dynamic mechanisms (DDNS or connection according to Client-to-Server scheme), where a remote branch with dynamic or grey IP address initiates a connection to the central server with a static IP itself.

Kill Switch — this is a security mechanism, which in case of sudden VPN-tunnel interruption instantly blocks all outgoing internet traffic on the user's device. This ensures that confidential data never goes into the open unprotected network during connectivity failures.
