Pricing
| Aspect | UnderDefense | Rapid7 MDR |
|---|---|---|
| Model | Per-endpoint | Quote-based |
| Starting Price | $11/endpoint/mo | Custom |
| Billing | Annual contracts | Custom |
| Free Trial | 14 days (up to ~100 employees) | Not stated |
| Transparency | Published floor; higher tiers hidden | Entirely opaque |
UnderDefense publishes a rare $11/endpoint/month starting point, though Standard, Enhanced, and Professional tiers require sales contact. All plans are annual commitments. Rapid7 MDR offers no public pricing—you’re getting a custom quote regardless of scale. For budget-conscious teams, UnderDefense’s transparency is a material advantage.
Features & Deployment
UnderDefense deploys hybrid (cloud + on-prem) and acts as an agentic AI overlay on any SIEM or XDR you already own. Its stack includes vendor-agnostic connectors, 24/7 concierge analysts, co-managed SIEM, ChatOps (Slack/Teams), and incident response retainers. The appeal: you’re not ripping out your existing security tools.
Rapid7 MDR is cloud-only and purpose-built on InsightIDR, Rapid7’s SIEM. It bundles threat intelligence, custom detections, and IR, but you’re locked into the platform. This is a traditional “one stack” approach—simpler operationally, but less flexible if you’ve invested elsewhere.
Verdict: Choose UnderDefense if you want platform independence and an AI boost to your current stack. Choose Rapid7 if you’re starting fresh or willing to consolidate on InsightIDR.
Ratings & Track Record
| Platform | UnderDefense | Rapid7 MDR |
|---|---|---|
| G2 Score | 4.9/5 | 4.5/5 |
| Review Count | 29 | 100 |
| Our Score | 8.1 | 7.3 |
UnderDefense has fewer reviews but higher sentiment per review—a signal of smaller but vocal user base. Rapid7’s larger review pool reflects enterprise adoption but slightly lower satisfaction. UnderDefense’s higher overall score reflects its niche strength (vendor-agnostic SOC automation), while Rapid7’s is tempered by platform lock-in complaints.
Verdict
Choose UnderDefense if you value flexibility, published pricing, and an AI-driven analyst overlay atop your existing SIEM/XDR.
Choose Rapid7 MDR if you want a unified platform from a large, proven vendor and don’t mind opaque pricing or consolidating on InsightIDR.
For teams with heterogeneous security tools and tight budgets, UnderDefense’s transparency and modularity win. For enterprises standardized on Rapid7 or building a new stack, Rapid7 MDR offers operational simplicity.
