IronNet and Mandiant Partner to Protect Public Sector and Commercial Supply Chains

 Mandiant's threat hunting and incident response and IronNet's Collective Defense to provide cyber defense services to organizations of all sizes.

IronNet, the market leader in network detection and response (NDR) and cyber collective defense, and Mandiant, a part of FireEye, Inc., today announced a partnership to provide best-in-breed managed cyber defense capabilities to companies and government agencies of all sizes across the globe.

"We are teaming with IronNet for the kind of network protection and detection capabilities that enable us to help eliminate or minimize the impact of security breaches, and to create a dynamic cyber defense. We have both seen organizations and agencies impacted by sophisticated attacks and share in the same mission of delivering collective defense for these customers," said Kevin Mandia, CEO of FireEye Mandiant.

IronNet and Mandiant's new jointly managed collective defense service offering removes the burden of identifying new and novel threats from public and private security teams by providing a potent software and services combination. Under the joint service offering, Mandiant's expert cyber threat hunting, assessment, and incident response teams utilize the combined capabilities of IronNet's powerful NDR solution, IronDefense, and its IronDome global collective defense solution, as well as Mandiant's industry-leading threat intelligence and continuous security validation capabilities.

"In many ways, bringing the IronDome collective defense platform's capabilities to a huge range of new customers in the public and private sectors and their supply chains by combining it with Mandiant's best-in-class hunters and incident responders, is exactly what our customers and prospects have been telling us they need right now," said IronNet co-CEO Bill Welch.

The combined offering is designed to allow organizations to scale their threat detection and hunting across not only their own networks but those of their customers and supply chain partners as well. By combining the vast breadth of real-time threat intelligence collected by IronNet and Mandiant, this new offering also enables large and small organizations alike to benefit from the combined learnings of hundreds of IronNet and Mandiant customers in critical industries including energy, financial services, healthcare, and the public sector across the United States, Europe, Asia-Pacific, and Middle East.

Tom Wilson, Chief Information Security Officer of Southern Company, a leading energy company serving nine million customers across the United States, said, "The combination of capabilities that these two key cybersecurity providers bring to the table will help security teams more effectively identify and stop threats targeting public and private sector organizations."

Wilson, whose company provides electric power generation, natural gas and electricity distribution, and fiber optics and telecommunications services across a number of states and works closely with local, state, and federal organizations added, "By helping companies stop threats in their own networks and scale across multiple organizations and industries, the joint capabilities of these two companies has the potential to be game-changing."

"Combining the Mandiant team's stellar skill set with IronNet's NDR and collective defense platforms is the way we are going to scale cyber collective defense across a huge number of new partners and customers, truly delivering on our vision of cyber collective defense for industries and nations," said GEN (Ret.) Keith B. Alexander, founder and co-CEO of IronNet and former Director of the National Security Agency (NSA) and Founding Commander of U.S. Cyber Command.
