The agreement pairs CyberMaxx's layered response with Avertium's Microsoft security, professional services, and GRC expertise, creating a single MDR partner across the full security journey.
LINTHICUM HEIGHTS, Md. — September 16, 2026 – CyberMaxx, a leading provider of Managed Detection and Response (MDR) services for the mid-market, today announced it has acquired Avertium, a premier Microsoft-focused cybersecurity firm with deep expertise in Governance, Risk, and Compliance (GRC) and offensive security services. The transaction closed on September 11, 2026, and strengthens CyberMaxx's ability to defend mid-market organizations against the five critical attack vectors and AI-driven attacks — meeting customers wherever they are on their security journey.
The combination brings Avertium's proven “Assess, Design, Protect” approach into CyberMaxx, and CyberMaxx will anchor the combined company's strategy on it going forward. Avertium's GRC advisory, security architecture, and Microsoft-focused services expand what CyberMaxx has been delivering for its customers and partners. That expansion lets CyberMaxx meet mid-market organizations wherever they are on their security journey: assessing risk for a customer just starting out, designing the architecture for one mid-transformation, or moving straight into continuous protection for a customer whose defenses are already mature.
“Acquiring Avertium furthers our commitment to serving the mid-market,” said Brian M. Ahern, CEO, CyberMaxx. “The mid-market deserves a security partner that stands with them on the wall all the way through remediation, and Avertium helps us do that to the best of our ability. We can now walk alongside a customer from their first security assessment through continuous defense, as their single committed partner.”
Avertium’s deep Microsoft expertise complements CyberMaxx’s tech-enabled strategy and further strengthens the combined company’s ability to deliver enterprise-grade cybersecurity outcomes to the mid-market. As a Microsoft Security Solutions Partner and member of the Microsoft Intelligent Security Association (MISA), Avertium brings extensive expertise across Microsoft Security with specialized capabilities spanning Microsoft Defender, Sentinel, Entra, Purview, Intune, and Copilot. Avertium is also an Elite Security Partner, a member of the Microsoft Partner Advisory Council, the 2026 Security Trailblazer Award winner, and a verified MXDR provider, with a proven track record of helping organizations operationalize Microsoft technologies and maximize their existing investments.
The mid-market cybersecurity space is crowded with point solutions and generalist providers. CyberMaxx has built its reputation on delivering enterprise-grade MDR outcomes with the response mid-market organizations deserve, and Avertium further strengthens that differentiation. This acquisition reinforces CyberMaxx’s durability model and allows the company to focus on increased investment in a scalable, tech-enabled, and AI-driven service that deliver the best outcomes for customers.
CyberMaxx will continue to offer its industry-leading MaxxMDR services for layered protection across the five vectors attackers weaponize most, paired with defense against the AI-driven risk moving across those vectors faster than ever, while bolstering its offensive services and GRC offerings. CyberMaxx has always believed offense fuels defense, and the expanded capabilities, alongside penetration testing, Continuous Threat Exposure Management (CTEM), and purple teaming, allow CyberMaxx to serve customers proactively, not just reactively.
“CyberMaxx was the right partner for Avertium because of a shared commitment to the mid-market and genuine complementary services,” said Vicente Velez, CEO, Avertium. “Our customers gain a deeper, more durable security partner, and our team gains access to an expanded platform, broader career opportunities, and the resources to deliver even better outcomes. I'm proud of what Avertium has built and excited for what comes next.”
