Pricing
| Aspect | UnderDefense | Arctic Wolf |
|---|---|---|
| Model | Per-endpoint | Quote-based |
| Published floor | $11/endpoint/mo | Not disclosed |
| Billing | Annual contracts | Quote/contract |
| Free trial | 14 days (up to ~100 employees) | None listed |
| Transparency | High (published pricing) | Low (sales-driven) |
UnderDefense publishes a concrete $11/endpoint/month starting price, a rarity in managed detection. Higher tiers (Standard, Enhanced, Professional) move to contact-sales, but you have a baseline. Arctic Wolf withholds all pricing—typical for MDR vendors targeting mid-market, but it means budget uncertainty until late-stage talks.
Features & Deployment
UnderDefense deploys hybrid (cloud + on-prem) and positions itself as a vendor-agnostic AI SOC overlay. It runs on top of your existing SIEM or XDR—Splunk, Elastic, CrowdStrike, Sentinel, etc.—and layers agentic AI, 24/7 concierge analysts, ChatOps (Slack/Teams), co-managed SIEM, and incident response retainers. This is a “bring your own SIEM” play.
Arctic Wolf is cloud-native MDR with a dedicated concierge team, managed risk/vulnerability, 24/7 SOC, log retention, and incident response. It’s an all-in-one managed service—you don’t need a separate SIEM; Arctic Wolf owns the stack.
Winner by use case:
- Multi-tool shops: UnderDefense (maximizes existing investments)
- Turnkey preference: Arctic Wolf (single vendor, named team)
Ratings & Verdict
| Metric | UnderDefense | Arctic Wolf |
|---|---|---|
| G2 Score | 4.9/5 | 4.7/5 |
| G2 Reviews | 29 | 250 |
| Our Score | 8.1 | 7.8 |
UnderDefense edges both on raw ratings, but Arctic Wolf’s 250 reviews offer more statistical weight. UnderDefense’s smaller review base reflects its newer/more specialized positioning.
Verdict:
- Choose UnderDefense if you already own a SIEM/XDR and want AI-driven analysis on top without rip-and-replace. The $11 floor and 14-day trial lower barrier to entry. Best for teams that want cost visibility and vendor flexibility.
- Choose Arctic Wolf if you want a named security team, managed vulnerability, and a complete handoff—willing to trade pricing opacity and annual contracts for operational simplicity and proven outcomes at scale.
