Robust Security, Effortless Management

Easy and Secure Protocol Conversion for the Modern OT Network

What is an MGate (Protocol Gateway)?

MGate protocol gateways act as translators between different industrial protocols. They enable seamless interoperability and optimize data traffic for better SCADA performance. The latest MGate MB3x70-G2 Series further speeds up system response times via Agent ModeActive Polling: Agent Mode actively polls data in the background and serves cached data to SCADA systems instantly, bypassing the latency of traditional transparent gateways. and effortlessly connects nonstandard assets to Ethernet networks without complex coding through built-in proprietary serialNo PLC Programming: Simplifies integration by allowing you to bridge almost any custom serial equipment to Ethernet without rewriting PLC programs. support.

Stop Guessing, Start Fixing With NPort and MGate G2’s Web-based Console

Field engineers know the frustration: a device goes down, you're on-site with no tools and no visibility. The NPort and MGate G2's built-in Web Console changes that. Access full diagnostics from any browser — no software needed. One-click Diagnostics pinpoints the issue instantly. One click exports a complete system log. Stop guessing, start fixing. Go home on time.

Is Your Edge Network Secure? See How NPort and MGate G2 Handle All 7 Checks

Is your industrial edge network truly secure? There are seven things every OT network needs to get right. In this video, see how the NPort and MGate G2 checks every box — from password policies and Secure Boot, to encryption, access control, event logging, and centralized authentication. Move from critical risk to operational confidence.

Edge Security Assessment

How defensible is your edge? Evaluate vulnerabilities in your current setup.

1. Login Security

Can anyone log in to your devices using default account and passwords (like "admin" or "1234") and get full access permissions?

Requirement: Forced Credential Update & Role-based Authorization
2. Data Encryption

Is the data traveling between your serial device and the network readable by anyone with a wiretap?

Requirement: HTTPS / SSH / SSL encryption
3. Access Control

Can any random computer on the network connect to your critical serial gateways?

Requirement: IP Whitelisting / Access Control List (ACL) / Service Disable
4. Antitampering

If a hacker installs fake firmware on your device, will the device refuse to run it?

Requirement: Secure Boot/Hardware Root of Trust
5. Digital Footprints

If someone changes a setting or reboots a device at 3 AM, will you have a record of who did it?

Requirement: System Log / Incident Logging / Timestamp
6. Security Updates

Have your gateways received any security patches or firmware updates in the last 24 months?

Requirement: Vendor vulnerability management

Maintenance Tax
Unmanaged Nodes: Conventional setups require device-by-device patching and troubleshooting.
5 Hrs/Year: Average time spent per device on manual maintenance tasks.
USD 60/hr: Average fully loaded cost for a skilled OT technician.
Formula: Unmanaged Nodes × 5 hrs × USD 60/hr
Formula: Unmanaged Nodes × 5 hrs × USD 60/hr

Regulatory Exposure
As cybersecurity regulations tighten globally, your customers' unmanaged edge nodes expose them to significant compliance risks.
Regulatory Fines: Typically 1 to 4% of annual revenue depending on jurisdiction and sector.
Contractual Penalties: Breaches of service contracts triggered by security incidents.
Market Access: Import/export restrictions that could bar you from key markets.
Formula: Revenue × 2.5%
Annual Cyber Risk
ALE Model: Probabilistic annual loss estimate based on OT breach cost benchmarks.
OT Dependency: Higher dependency means greater financial impact per incident.
0.4%: Baseline breach probability for unpatched edge environments.
