With this week’s announcement of the take-private acquisition by Thoma Bravo, Sophos begins an exciting new chapter of continued growth, success, and industry leadership. As a private company, Sophos intends to further accelerate our mission to protect people from cybercrime by developing powerful and intuitive products and services that provide the world’s most effective cybersecurity for organizations of any size.
As part of this announcement, I want to affirm our commitment to you, our partners, that the channel remains at the forefront of our strategy. Our Channel Best commitment is a big part of what has driven our success, both as a private and public company. Channel Best means that we strive to have the very best training, enablement, resources, support, and programs to ensure the success of our partner community.
Thanks to all of you, Sophos is winning in the marketplace. Our next-gen product portfolio, all managed in our Sophos Central cloud-management platform, now comprises over 60% of our total company billings and is growing 44% year-over-year (YOY). Our XG Firewall business grew 47% in the most recent quarter, and just last month we launched our most significant network security technology ever, Sophos XG Firewall v18 with the Xstream architecture. We are seeing substantial growth not only in network security, but across our entire next-gen product line from endpoint and server security to mobile, email, and cloud security. Our new Managed Threat Response (MTR) service launched last October has seen rapid adoption, and now protects hundreds of customers around the world with advanced, 24/7 threat detection and response. We continue to take share from our competitors, and our managed service provider (MSP) business, which is a strategic priority, is growing at over 75% YOY. Sophos continues to drive market-leading innovation, and we are filling the cybersecurity void left by fading, less nimble, and less evolved vendors.
With the full support and experience of Thoma Bravo behind us, we believe we can accelerate the next-gen transition we already have well underway and get to the future even faster, enabling us to deliver enhanced cybersecurity solutions for our customers and dramatic new business opportunities for all of you, our partners.
This take-private acquisition is a historic milestone in the ongoing journey of Sophos and a springboard to our next phase of growth and success. I’m tremendously excited about the opportunities ahead. Thank you for your continued support. We greatly value your partnership and look forward to sharing this next exciting stage in the Sophos journey with you.
