Expel

What Expel actually does

Expel is a managed detection and response provider that connects to your existing security stack — EDR, SIEM, cloud, identity, and network tools — and provides 24/7 monitoring, investigation, and response. What sets Expel apart is the Expel Workbench, a customer-facing portal that shows every alert, every investigation decision, and every action taken in real time.

The philosophy is radical transparency. Most MDR providers operate as a black box — you send them telemetry, they send you alerts. Expel shows you the work. You can see what their analysts looked at, why they escalated or closed an alert, and what response actions were taken. This approach builds trust and helps internal teams learn from the investigations.

Expel also provides resilience recommendations — proactive advice on how to harden your environment based on patterns they observe across their customer base. These are not generic suggestions. They are specific to your environment and tied to real threats.

Who it’s best for

• Mid-market and enterprise organizations that want MDR with accountability
• Security teams that want to learn from their MDR provider, not just outsource
• Companies running multi-vendor security stacks that need unified monitoring
• Organizations that have been burned by opaque MSSP relationships
• CISOs who need to demonstrate to the board exactly what their security investment delivers

Pricing reality check

Expel prices based on the number and type of integrations monitored. EDR, cloud, SIEM, and identity sources each contribute to the overall cost. Expect mid-to-high five figures for a typical mid-market deployment, scaling into six figures with more integrations and endpoints.

The pricing is competitive with other premium MDR providers like Red Canary and Arctic Wolf. The transparency model means you can actually verify you are getting value — you can see investigation volumes, response times, and detection quality in the Workbench. That accountability is worth something, especially when justifying the spend to leadership.

Alternatives to consider

• Red Canary — Similar quality MDR with strong ATT&CK-based detections. Less emphasis on the customer portal experience.
• Arctic Wolf — Dedicated security team model. Broader scope but less transparency into the analysis process.
• Rapid7 MDR — InsightIDR-based MDR with competitive pricing. Less polish in the customer experience.
• Todyl — Newer entrant targeting mid-market. Lower cost. Less proven at scale.

The Charting Cyber take

Expel has built something genuinely different in the MDR market. The Workbench is not just a marketing feature — it changes the relationship between customer and provider. Being able to see every investigation in real time means you can hold Expel accountable, learn from their work, and build institutional knowledge even while outsourcing detection.

The caveat is that transparency only matters if you use it. If your team never logs into the Workbench, you are paying a premium for a capability you are ignoring. Expel works best for organizations with at least one security person who actively reviews investigations and uses the resilience recommendations. If you just want someone to handle alerts and page you when it is bad, a less premium MDR provider may be a more honest fit.
