Ostra Security delivers MXDRR: Managed Extended Detection, Response, and Remediation. 

We added the extra ‘R’ because traditional MDR and XDR often stop short. They detect a threat, isolate a device, and send an alert. Ostra goes further: helping investigate incidents, contain threats, identify root cause, and remediate the gaps behind them. That end-to-end approach is what real security requires. 

We built Ostra for organizations that need enterprise-grade security outcomes without the cost and complexity of building a full in-house SOC. Our model is designed for lean IT and security teams, growing organizations, and businesses that want strong protection without sacrificing visibility or control. 

Through our managed platform, customers can see what we see: detections, investigations, and remediation activity in real time. No black box. No mystery. Just clear visibility, practical action, and a team that works alongside yours. No cybersecurity checkbox here. 

We also believe better detection starts with better visibility. More data helps us detect threats more effectively, which is why we do not charge based on data volume. Our pricing model supports stronger security outcomes — not limits on what your environment sends us. 

Founded in 2018 and headquartered in Eden Prairie, Minnesota, Ostra is backed by General Catalyst and Rally Ventures and continues to grow across security operations, engineering, and go-to-market. 

If your team is carrying security on top of everything else — and your current provider still leaves the hard part to you — we should talk.
