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.

Built-in Web Console: Troubleshooting in the Field Without the Guesswork

The NPort G2 and MGate G2 web-based consoles are accessible from any browser with no installation needed. Real-time traffic visibility and one-click diagnostics tell you what went wrong and where. One-click system log export handles the paperwork. When a machine is down, the last thing you need is more uncertainty.

7 Security Checks: Is Your Edge Network Equipped for Cyberthreats?

In this video, we walk through seven real security scenarios every industrial network faces: default credentials that leave the door wide open, firmware that could be tampered with at start up, data transmissions vulnerable to wiretapping, unauthorized devices connecting to your network, configuration changes with no audit trail, and device authentication that doesn't scale.

Check Your Connectivity Readiness

Benchmark your current device security against industry standards and estimate the potential value of modernization.

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

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.
