Blumira: Detection And Response Technology Company Secures $15 Million

By Amit Chowdhry • Jul 3, 2023

Blumira – a leading provider of detection and response technology – recently announced the launch of its XDR platform to provide enterprise-level security for small to medium businesses (SMBs). And the company also recently announced that it had raised a $15 million Series B financing round led by Ten Eleven Ventures and joined by RPS Ventures, Mercury Fund, HPA, and Duo Security co-founder Jon Oberheide.

The company’s XDR platform combines SIEM, endpoint visibility, and automated response to help organizations with lean IT teams consolidate tools, reduce complexity, integrate broadly to provide insight across their entire environment, and use automation to speed up the response.

Blumira’s XDR platform essentially saves IT teams time and effort in threat response. And automated host isolation enables them to immediately contain an endpoint threat until they can investigate it further.

Most XDR solutions on the market today have been built for larger enterprises with more resources, time, and security expertise. And in a recent whitepaper, Blumira shared that it is harder than ever for small or medium-sized businesses to deal with ransomware and data breaches. According to SMB Group, in the last twelve months, 42% of SMBs said their company has experienced a data breach and 26% have experienced a ransomware attack (Directions For the Future of Work, SMB Group 2022).

From its inception, Blumira’s team has been focused on improving ease of use and measurable security outcomes for lean IT teams.

Blumira has seen tremendous momentum in the past year with 100% year-over-year customer growth, including an 8x growth in the MSP channel with customers in every vertical, including manufacturing and healthcare industries, as well as credit unions, colleges, universities, and municipalities.


“We are excited to announce the launch of our open XDR platform for small and medium-sized businesses alongside our Series B fundraising announcement. Security remains a significant manual lift for small teams. We think there’s a huge opportunity to deliver simplified security for the SMB market, reducing reliance on people to complete manual security tasks to help companies achieve faster time to security. We meet customers where they are by offering a full range of detection and response options, from our Free SIEM to our all-in-one XDR solution, which eliminates redundancies and provides full hybrid coverage.”

“If system administrators are unavailable during a critical incident, host isolation would cut off communication until they can get their hands to the keyboard, preventing headaches for IT administrators everywhere.”

— Brian Johnson, president of 7 Minute Security, a cybersecurity services firm

“With their talent, experience, customer base, laser focus, and Duo background, this is the team and technology that will open up security for small and medium enterprises in a totally new way. We’re thrilled to support them on this journey and are pleased to be joined by an experienced set of co-investors in this new round, who we know will all be helpful to the Blumira team during the next chapter.”
