Back in April 2019, the Menlo Security team learned that our Partner By Light IT Professional Services LLC and Menlo Security were one of two solution providers selected to design and implement a Cloud Based Internet Isolation (CBII) prototype capability for the Defense Information Systems Agency (DISA).

After an exhaustive, large-scale prototyping phase lasting over 18 months, DISA announced last month that it had awarded the 5 year, $198.9 million Other Transaction Agreement (OTA) contract for the CBII to our partner By Light as the prime contractor. Together with the By Light team, we are delivering this next-generation security platform to secure Department of Defense (DoD) networks worldwide.

We started working with the CBII Program Management Office (PMO) and the By Light team on this program 18 months ago, so we are beyond thrilled with this outcome! We are very proud of what the combined teams have accomplished and the impact this large-scale production will have by serving DoD users worldwide. This project is truly groundbreaking in its scope and scale and is a true testament to the value of the Menlo Security Isolation Core architecture to deliver security and scalability solutions to help defend the cross domain users of the DoD Information Network (DODIN).

Securing the most demanding and the most highly targeted environments in the world is what we do best –We are committed to protecting all of our customers against the most prevalent and sophisticated attack vectors such as phishing and ransomware vulnerabilities. It’s of the utmost importance to us at Menlo to help secure the infrastructure, systems, and people who protect us. We are humbled to be part of this initiative and dedicated to the successful outcomes of this program for years to come as we expand deployments across mission partners and geographies.

DISA Awards By Light Team $198.9M Cloud-Based Internet Isolation Production OTA

By Light partners with Menlo Security to help protect Department of Defense (DoD) networks worldwide

MCLEAN, VA—September 14, 2020—By Light Professional IT Services LLC has been awarded a $198.9M, 5-year production Other Transaction Agreement (OTA) by the Defense Information Systems Agency (DISA) for the Cloud-Based Internet Isolation (CBII) Program. By Light as the prime contractor for this OTA, with teammate Menlo Security, Inc., are together delivering this next-generation Isolation Platform to protect Department of Defense (DoD) networks worldwide.

Beginning in March 2019, By Light and Menlo worked closely with the DISA CBII Program Management Office (PMO) to design and implement the CBII prototype capability which eliminates most web-based threats such as drive-by-downloads. This technology removes the browsing process from the desktop and moves it to the cloud, effectively creating an “air gap” between the Internet and enterprise networks. The successful implementation of this effort will directly enhance military and civilian personnel’s ability to defend the DoD Information Network (DODIN).

According to Bob Donahue, By Light CEO, “This win culminates more than 18 months of working closely with Menlo, DISA, and its Mission Partners to shape the commercial application of Menlo’s Global Cloud Secure Web Gateway (SWG) to improve DoD’s information security posture for those entities conducting business across the Internet. Our CBII solution improves the security posture of the network, will scale to meet DoD needs, is easy to deploy and manage, and optimizes and reduces bandwidth – thereby extending the life of the network.”

“This isolation technology allows enterprises to separate their network from the public web while providing users seamless access to the Internet with a native browser experience,” says Joe Boyd, By Light VP and CBII Program Manager. “Within the cloud native architecture, all components scale horizontally. You couple this with global availability, anytime/anywhere access, always-on cloud with failover between regions, instant on-boarding of users, 24x7x365 operations support, and what you get is an enterprise-class cybersecurity capability virtually eliminating Internet browsing threats traversing the Internet Access Points (IAPs) while also optimizing and reducing bandwidth utilization.”

“We’re truly humbled to partner with By Light on this groundbreaking program with DISA,” said Poornima DeBolle, Chief Product Officer, Menlo Security. “Our partnership with the By Light team and the CBII Program Management Office (PMO) is a true testament to the value of the Menlo Security ‘Isolation Core’ architecture to deliver on their security and scalability needs to help defend the users of the DoD Information Network (DODIN).”About By Light
