CyberMaxx

CyberMaxx is a managed detection and response (MDR) provider headquartered in Linthicum Heights, Maryland, delivering 24/7 SOC-backed monitoring across endpoint (MAXX EDR), network (MAXX NETWORK), and SIEM (MAXX SIEM) telemetry, along with email security following its 2024 acquisition of Corvid Cyberdefense. The company frames its methodology as “offense fuels defense” — using its own offensive-security and penetration-testing bench, expanded through the 2023 acquisition of CipherTechs, to inform detection content and incident-response playbooks rather than treating red-team and blue-team functions as separate business lines.

CyberMaxx’s recent history is one of consolidation: in 2025 it acquired both Cybersafe Solutions (a Melville, NY-based continuous-MDR provider, formerly assessed as a candidate for this list under its own name before the deal closed) and onShore Security, positioning the combined company as a top-15 MDR provider by revenue. Cybersafe’s domain now redirects directly to CyberMaxx’s site, and its CyberSAFE platform and customer base have been folded into CyberMaxx’s operations rather than run as an independent brand.

For CISOs evaluating MDR vendors, CyberMaxx’s pitch is a single vendor spanning offensive security assessment, DFIR, GRC advisory (via CipherTechs), and always-on detection and response — useful for mid-market and regulated organizations that want one contract instead of stitching together a pentest firm, an MDR provider, and an incident-response retainer separately. The tradeoff is integration risk: the company is actively merging several distinct acquired platforms and teams (Corvid, CipherTechs, Cybersafe, onShore) into a common service delivery model, and prospective customers should ask specifically which acquired capability is fully integrated versus still operating on legacy tooling.
