Core MXDR Platform
Ontinue ION
Operationalizing security is hard. Security teams are understaffed and overwhelmed with tools and alerts. Thousands of decisions to make each day. And the increasing pressure to do more with less. Ontinue ION is the MXDR service of choice for Microsoft Security customers who want to accelerate MTTR, proactively reduce risk, and reduce costs.
ION does more than merely detect threats. It delivers proactive threat-hunting and AI-driven automation to eliminate noise. And empower you to make smarter, faster decisions that reduce your MTTR. All using Microsoft Security tools you already own.
Our one-of-a-kind Microsoft Teams integration provides real-time access to a team of designated security experts. These Cyber Advisors are the experts who learn your unique business, environment, and operational realities. This localized knowledge allows Ontinue ION to continuously reduce risk. Mitigate threats. And accelerate your security program development to make you stronger. Nonstop.

Add-on Service
Managed Vulnerability Mitigation (MVM)
More than 20,000 new vulnerabilities emerge each year. So it’s easy to assume that the vulnerability mitigation challenge is about scale. But since only 25% of vulnerabilities are exploited, the challenge is really about focus. Adding our MVM service to Ontinue ION gives you a prioritized set of your highest risk vulnerabilities. You’ll also receive intelligent response recommendations specific to your organization and risk levels.
Your Ontinue Cyber Advisor gives you best practices for vulnerability mitigation. So you can mitigate the highest risks with the least effort. Our 24/7 Cyber Defender team learns from these insights to aid in prioritization and investigation, improving our ability to detect and respond to future threats.

Add-on Service
Internet of Things (IoT) Security
The expanding adoption of the IoT and deep connectivity of Operational Technology (OT) have delivered unprecedented convenience and efficiency through hundreds of thousands of connected devices. The dark side? This far-ranging, ever-connected convenience can pose even more security risks to companies like yours.
Ontinue ION offers an IoT security add-on service to its MXDR platform for around-the-clock, around-the-world IoT and OT threat detection. Our proprietary detection logic works with Microsoft Defender to intelligently and efficiently correlate alerts, indicating threats that might otherwise go unnoticed. This approach detects threats with a higher degree of confidence—and delivers recommended responses directly to the right team members, through tools already at their fingertips. This unsurpassed combination of automation, localization, and collaboration also results in unprecedented response times.
