Managed Detection & Response

A fully staffed SOC at your service

Get SOC-driven detection and response across endpoints, network, identity, cloud, and emails, backed by experts who cut through alert noise and elevate what matters.

Attackers don’t work 9 to 5.

Most organizations don’t have the headcount, budget, or appetite to staff a 24x7 security operations center. But threats don’t stick to business hours. Ransomware lands at 2 a.m. on Saturday, or phishing campaigns hit inboxes over holiday break. For many organizations, security “solutions” have become a problem as they generate thousands of alerts a day. Without analysts who know what to escalate, alert fatigue sets in and real threats slip through.

What’s needed is a layer most internal teams can’t build themselves: 24x7 monitoring, expert human judgment, and technology to detect what matters before it becomes an incident.

The OnX approach

A SOC built for coverage and context

The OnX Security Operations Center combines four elements:

  • Continuous monitoring, with 24x7 coverage across endpoints, network, identity, cloud workloads, and email backed by SIEM, EDR, and XDR platforms tuned to your environment

  • AI & human analysts working together, with AI automating investigation and senior analysts applying context that automated tools lack

  • Active response to real threats, including isolating endpoints, blocking accounts, and coordinating with your team on next steps

  • Continuous tuning to refine detection logic, suppress recurring noise, and adjust thresholds; the SOC keeps getting smarter about your business

This is detection as a discipline rather than a data feed.

Managed Detection & Response capabilities

Implement a more strategic and proactive approach to detecting and responding to security threats across your environment.

Managed Email and Collaboration Protection


Proactive filtering, threat detection, and incident response for the communication channels used every day. Our managed email and collaboration protection blocks phishing, business email compromise, and malware before they reach inboxes and gives your users the training and reporting tools to flag what gets through.

SOC Managed Detection and Response (SIEM/EDR/XDR)


24x7 monitoring by experienced security analysts using SIEM, endpoint detection and response, and extended detection across hybrid environments. We collect, correlate, and analyze telemetry from endpoints, network, identity, cloud, and SaaS. Using up-to-date threat intelligence, we prioritize and escalate threats with the context your team needs to act. Active response capabilities include isolation, containment, and incident handoff.

Where to start

Advisory engagements

A CBTS advisory is a time-bound, fixed-fee engagement designed to give you a clear answer to a specific strategic question — fast.  

AI & Data Maturity Assessment

Best for organizations that want a clear, third-party read on where they stand on AI and data readiness and where to focus first.

You walk away with: 


  • Current-state assessment across both AI and data dimensions
  • Gap analysis against industry benchmarks and your own stated AI ambitions
  • Prioritized list of foundational gaps to close before scaling AI investment
  • Short-form executive readout deck for leadership alignment

What success looks like

Disciplined detection and response drives tangible improvements for your organization.

Reduced risk

Detect and contain threats before they become breaches. Compress the time between intrusion and response, which is the single biggest variable in incident cost.

Improved productivity

Stop drowning your team in alerts that don’t matter. Free internal staff to focus on engineering and strategic work.

Operational excellence

Compliance-ready monitoring, reporting, and documentation is available around the clock. Replace gaps and guesswork with a SOC discipline that scales with your business.

“Attackers aren’t sending humans anymore. They’re sending models. The only credible answer is to meet AI with AI, and to do that well you need the kind of deep infrastructure visibility most MSSPs simply don’t have. Our fusion centers sit at the intersection of that hardware expertise and modern AI-enabled detection.”

Frequently asked questions 

What’s the difference between SIEM, EDR, and XDR? SIEM (Security Information and Event Management) collects and correlates log data from across your environment, including firewalls, servers, applications, and cloud services, to surface anomalies and support investigation and compliance. EDR (Endpoint Detection and Response) focuses specifically on endpoint activity, using behavioral analysis to detect threats that bypass antivirus and enabling rapid containment. XDR (Extended Detection and Response) unifies telemetry across endpoints, network, identity, email, and cloud into a single platform with coordinated detection logic. OnX MDR uses all three layers, with SOC analysts correlating signals across them to surface real threats faster than any single tool could on its own.
How does Onx reduce alert fatigue? OnX reduces alert fatigue in two ways: tuning and triage. We tune SIEM, EDR, and XDR platforms to your environment, suppressing the noise that creates fatigue in the first place (e.g., known-good behaviors, expected administrative activity, and business-specific patterns). We also triage every alert that does fire, applying analyst judgment before anything reaches your team. The result is fewer escalations, but every escalation is real and actionable.
What’s included in Managed Email Protection? Proactive filtering against phishing, business email compromise, malware, and impersonation attacks; quarantine and review tooling for end users and administrators; threat intelligence integrated into detection logic; user awareness reporting; and incident response when a malicious message gets through. Coverage spans Microsoft 365, Google Workspace, and hybrid email environments, with reporting that supports operational, executive, and compliance audiences.
How does the OnX SOC handle hybrid and cloud environments? Hybrid is the default. Our SOC ingests telemetry from on-premises, cloud, and SaaS environments, including AWS, Azure, GCP, Microsoft 365, Google Workspace, and major SaaS platforms, and correlates activity across all of them. We map detection logic to the unique threats and behaviors of each environment, then unify findings into a single view your team can act on. Adding a new cloud workload or SaaS platform doesn’t require standing up a separate monitoring stream.
Can we integrate our existing security tools with OnX MDR? In most cases, yes. OnX Managed Detection & Response is designed to work with the security investments you’ve already made. We support major SIEM, EDR, and XDR platforms, integrate with identity providers, and ingest telemetry from third-party tools that have meaningful detection value. We’ll evaluate your current stack as part of onboarding, identify what to keep, what to consolidate, and where to add coverage. Ultimately, we build an integrated detection environment around what’s already working.

Detect what’s real. Respond before it spreads.

Cut through alert noise, surface real issues, and respond with speed and confidence.
