What's the deal? CyberMaxxDealroom has a profile for this one. Try Dealroom →, a Maryland-based provider of Managed Detection and Response (MDR) services for the mid-market, has acquired AvertiumDealroom has a profile for this one. Try Dealroom →, a Microsoft-focused cybersecurity firm. The deal closed on September 11, 2026. Terms were not disclosed.
What each company does: CyberMaxx sells MDR services built to defend mid-market organisations against common attack vectors and AI-driven threats. Avertium specialises in Governance, Risk, and Compliance (GRC) advisory, security architecture, and offensive security, with deep Microsoft expertise across Defender, Sentinel, Entra, Purview, Intune, and Copilot.
The rationale: The acquisition folds Avertium's "Assess, Design, Protect" methodology into CyberMaxx, which will anchor the combined company's strategy on it. That lets CyberMaxx serve customers at any stage — from a first risk assessment to continuous protection.
What changes for customers? CyberMaxx will keep offering its MaxxMDR services while adding Avertium's GRC and offensive capabilities, including penetration testing, Continuous Threat Exposure Management (CTEM), and purple teaming. Avertium is a Microsoft Security Solutions Partner and member of the Microsoft Intelligent Security Association.
"Acquiring Avertium furthers our commitment to serving the mid-market," said Brian M. Ahern, chief executive officer of CyberMaxx. "We can now walk alongside a customer from their first security assessment through continuous defense, as their single committed partner."
Why now? The mid-market cybersecurity space is crowded with point solutions and generalist providers. CyberMaxx frames the deal as reinforcing its differentiation and enabling more investment in scalable, AI-driven services.
Avertium's CEO, Vicente Velez, said the two firms shared "a shared commitment to the mid-market and genuine complementary services," adding that customers gain "a deeper, more durable security partner."
The signal: The deal reflects consolidation in mid-market security, as buyers seek to combine detection, compliance, and offensive services under one roof. By absorbing a Microsoft specialist, CyberMaxx bets that customers want a single partner spanning assessment through continuous defence rather than a patchwork of vendors.
