Security startup Bayshore Networks announced on March 20 that it has raised $11 million in a oversubscribed round of funding. The new venture capital infusion will be used to help expand Bayshore's go to market effort and industrial cyber security platform

The new funding marks the end of Bayshore's Series A, with a final investment coming in from Benhamou Global Ventures (BGV), bringing total investment to date in Bayshore to $15 million. Other investors include Trident Capital Cybersecurity and Samsung NEXT Ventures.

Bayshore's core product platform is the company's IT/OT Gateway for industrial cyber security. The promise of the IT/OT gateway is to go beyond what a traditional firewall is capable of defending to meet the specific needs of industrial environments.

According to Bayshore's product documentation, the gateway is able to inspect Layer 3, 4 and 7 traffic as well as provide machine isolation and network segmentation capabilities.

"It can filter OT traffic to identify the actual machine operations commands and transaction values," Bayshore website explains. "With its inherent understanding of industrial protocols, it can identify machines by the type of application traffic they are sending and receiving."

The Bayshore Pallaton policy language is an XML-based technology that helps to enable the OT system protocol analysis on the gateway. With Pallaton, organization can understand what is going on in an OT environment and then create and enforce security policies.

"The market for Bayshore's industrial cyber protection solutions is expanding quickly," Mike Dager, CEO of Bayshore Networks, said in a statement. "Industrial cyber protection is now a key strategic initiative for large enterprises, utilities, and governments alike."

"We're experiencing rapid growth because unlike passive visualization and reporting packages, Bayshore's comprehensive industrial cyber protection platform stops industrial cyber threats before they start," he added.

Bayshore isn't the only security startup looking to help security industrial networks. In September 2016, security startup Claroty emerged from its stealth mode with $32 million in funding to help protect industrial control system.
