Vijilan vs Expel. Beside Falcon, not against it.
Expel is a genuinely strong MDR — a Forrester Wave Leader with real auto-remediation and best-in-class transparency through Workbench. The split comes down to structure and stack: Expel monitors the SIEM you keep paying for and positions against Falcon Complete; Vijilan's NextDefend runs CrowdStrike Falcon Next-Gen SIEM on the Falcon LogScale engine — index-free, Cribl-managed ingestion, AWS-hosted — as a managed service that works alongside Falcon Complete, with the SIEM included on an index-free engine and Cribl-controlled ingestion, delivered as a premium white-glove operation.
Expel earns its reputation: vendor-agnostic BYO-tech across 160+ integrations, real pre-approved auto-remediation, industry-leading transparency, and a Forrester Wave MDR Leader nod in Q1 2025. If you're a security-mature enterprise that wants a watch-every-move MDR over the tools you already own — and your SIEM is Sentinel or Splunk — Expel is a credible choice. Choose Vijilan when the structure and the stack matter: NextDefend is a CrowdStrike Powered Service Provider practice with 50+ Falcon Next-Gen SIEM environments that runs the SIEM alongside Falcon Complete rather than against it, on the index-free Falcon LogScale engine with Cribl-managed ingestion and AWS hosting; ThreatLog SIEM is included in the service — on an index-free engine, one provider owning platform, pipeline and SOC — instead of a monitoring layer on top of the Splunk or Sentinel bill you keep paying; hunting and sub-15-minute active containment are base inclusions, not add-ons; and the whole engagement runs as a premium, named-team white-glove operation.
Where Expel falls short.
Threat hunting is a paid add-on — not included in base MDR pricing.
Incident response is a separate add-on too — the capabilities you need most in a crisis sit behind upsells.
API-first overlay by design — Falcon is driven through an external console rather than operated natively.
Where Expel genuinely leads: Operational transparency — every analyst action visible in Workbench — and very fast API-based onboarding across 160+ integrations.
Why partners choose NextDefend™.
Threat hunting and IR are included, not itemized. NextDefend is native to Falcon — operating the platform directly, not managing it from the outside.
- Threat hunting is included in the service — not an upsell.
- Incident response is part of the subscription: ThreatContain™ acts as part of the service, not a separate SKU.
- Native to Falcon: engineered and operated by a CrowdStrike Powered Service Provider, not an agnostic overlay managing it from the outside.
Side by side. Feature by feature.
| Capability | Vijilan | Expel |
|---|---|---|
| Response model | 24/7 Global SOC actively contains threats via ThreatContain (isolate hosts, disable accounts, block IPs, kill processes) with sub-15-minute containment — included in ThreatRespond, and in ThreatDefend on top of it | Genuine pre-approved auto-remediation via your tools' APIs (contain host, disable AD/Entra ID/Okta account, block hash, remove email); full IR is a separate retainer |
| Underlying technology | Praxis AI SOC and triage engine + ThreatLog SIEM included; CrowdStrike Falcon stack on ThreatDefend/NextDefend; vendor-agnostic over your existing EDR on ThreatRespond | Workbench platform + Ruxie agentic AI; agentless, 160+ API integrations over your existing tools — no sensors or log platform of its own |
| Managed SIEM engineering | NextDefend: CrowdStrike Powered Service Provider, 50+ Falcon Next-Gen SIEM environments since 2023 — parsers, detections, dashboards, pipeline, 24/7 ops | Expel Managed SIEM (launched March 2026) offers detection/performance engineering only for Microsoft Sentinel and Splunk ES; Falcon Next-Gen SIEM is a supported MDR integration (added Feb 2026), but there is no Falcon NG-SIEM engineering practice — no parser, dashboard, or pipeline build-out |
| Works alongside Falcon Complete | Explicitly designed to complement it — Falcon Complete keeps MDR, Vijilan runs the SIEM (CrowdStrike has referred this pairing; see the Practising Law Institute case study) | Competes in the same MDR category as Falcon Complete (commonly evaluated as an alternative), though its integrations do support Falcon Complete powered by Next-Gen SIEM environments; offers no Falcon NG-SIEM engineering practice either way |
| SIEM & data economics | ThreatLog SIEM included in the service on the index-free LogScale engine — flexible pricing, per asset or by daily ingest volume | Priced by integrated technologies (no noisy-month surcharges, to its credit), but brings no SIEM — so Splunk or Sentinel licensing and ingest keep running on your bill in parallel |
| Log management & data pipeline | Falcon Next-Gen SIEM on the index-free Falcon LogScale engine, Cribl-managed ingestion (routing, cost control, compliance), AWS-hosted — index-free, with Cribl controlling ingest volume | No bundled SIEM or log platform of its own — agentless across 160+ integrations; your Splunk or Sentinel stays the licensed system of record you keep feeding |
| Proactive threat hunting | ThreatHunt — MITRE ATT&CK-mapped proactive hunting — included in ThreatRespond | Proactive threat hunting is a paid add-on above base MDR tiers; managed phishing is likewise a paid add-on |
| Customer-facing transparency | 24/7 SOC reporting with a dedicated named-team review cadence; no live, action-by-action console on par with Workbench History | Industry-benchmark: Workbench History shows every analyst and bot action live, in real time — a genuinely differentiated capability |
| Cloud-native & Kubernetes depth | Cloud is one of six managed domains (plus email and IoT/OT) | Deep AWS/Azure/GCP and Kubernetes detection plus strong identity/ITDR — broader cloud-native depth than most MDRs, extended by agentic AI in June 2026 |
| Best fit | Mid-market and enterprise Falcon Next-Gen SIEM adopters — especially alongside Falcon Complete — that want SIEM, hunting, and containment included and a premium, named-team managed service | Security-mature enterprises with existing tooling investments who want a Forrester-Leader MDR under Expel's brand and can absorb enterprise procurement |

Pick Vijilan when…
- You're adopting CrowdStrike Falcon Next-Gen SIEM and want a CrowdStrike Powered Service Provider with 50+ NG-SIEM environments delivered — Expel integrates with Falcon NG-SIEM but has no Falcon NG-SIEM engineering practice; its Managed SIEM service covers Sentinel and Splunk ES only
- You run (or are evaluating) Falcon Complete and need a SIEM operator that complements it instead of competing with it for the MDR seat
- You want the SIEM included in the service on an index-free engine, instead of monitoring a Splunk or Sentinel bill you keep paying in parallel
- You want the log platform run for you on modern infrastructure — Falcon Next-Gen SIEM on the index-free LogScale engine, Cribl-managed ingestion for routing and cost control, AWS-hosted — not monitoring bolted onto tools you still operate yourself
- You want proactive hunting (ThreatHunt) and active containment (ThreatContain) included in ThreatRespond, not priced as add-ons
- You want a premium, white-glove managed service — a dedicated named team, Praxis AI triage, and sub-15-minute containment — rather than a self-serve console you staff and watch yourself
Pick Expel when…
honest answer: they're a better fit in these cases
- You want to watch every analyst and AI action live — Workbench's real-time investigation history is the industry benchmark for MDR transparency
- Your estate is heavily cloud-native (AWS/Azure/GCP/Kubernetes) with mature identity infrastructure, and cloud/ITDR detection depth is your top criterion
- You run Microsoft Sentinel or Splunk Enterprise Security and want co-managed detection engineering inside that specific SIEM
- You're a security-mature enterprise buying MDR under the provider's brand and weight third-party validation heavily (Forrester Wave Leader Q1 2025, ~4.6/5 on Gartner Peer Insights)
- You want a proven AI automation pipeline — Ruxie's agentic triage, investigation, and response shipped to production in June 2026 with Slack/Teams collaboration
The Falcon Complete question
If you're standing up CrowdStrike Falcon Next-Gen SIEM — and especially if Falcon Complete already handles your MDR — the two vendors play different roles. Expel MDR competes in the same category as Falcon Complete and is commonly evaluated as an alternative to it; it added a Falcon Next-Gen SIEM MDR integration in February 2026, but its Managed SIEM engineering practice (March 2026) covers only Microsoft Sentinel and Splunk ES — Expel will consume Falcon NG-SIEM telemetry, not stand up and engineer the platform. NextDefend is built for exactly the engineering gap Expel doesn't cover: Vijilan is a CrowdStrike Powered Service Provider with 50+ Falcon NG-SIEM environments stood up since 2023, delivering parsers, custom detections, dashboards, and data-pipeline engineering with 24/7 SOC operations on top — in English, Spanish, and Portuguese. Where Falcon Complete is present, it keeps the MDR role and Vijilan runs the SIEM; that's the pairing CrowdStrike itself referred in the Practising Law Institute engagement. You don't have to choose between your MDR and your SIEM operator.
The SIEM bill nobody manages away
Expel's model is honest and consistent: it monitors the tools you already own, charges by integrated technologies rather than data volume, and doesn't surcharge noisy months. But it also brings no log platform — your Splunk or Sentinel licensing and ingest bill continues in parallel with the MDR subscription, and hunting, managed phishing, and IR retainers are separate line items on custom-quoted annual contracts, with onboarding fees commonly reported as separately billed. Vijilan structures the economics differently: ThreatLog SIEM is included in the service — it runs on the index-free Falcon LogScale engine, so there is no indexing tax on top of ingest, and Cribl-managed ingestion filters volume at the source — and ThreatHunt and ThreatContain are included in ThreatRespond, on flexible per-asset or per-ingest pricing. For enterprises consolidating onto Falcon NG-SIEM, NextDefend's professional-services onboarding replaces the pay-twice pattern with one managed platform and one SOC.
The stack behind the service — and the hands running it
Expel is deliberately a monitoring layer over the tools and SIEM you already run and license — agentless, 160+ integrations, no platform of its own — and Workbench's real-time transparency is built so your team can watch every analyst and bot action as it happens. For a security-mature team that wants to stay in the loop, that's a genuine strength. Vijilan is the other model: an operated stack, run for you. NextDefend delivers Falcon Next-Gen SIEM on the index-free Falcon LogScale engine, with Cribl-managed ingestion handling routing, cost control, and compliance, all hosted on AWS and triaged by the Praxis AI engine ahead of a 24/7 Global SOC (SOC 2 Type 2 and ISO 27001, with HIPAA, PCI, NIST, and CMMC alignment). It runs as a premium, white-glove operation — a dedicated named team, sub-15-minute containment, and delivery across multiple regions in English, Spanish, and Portuguese. For a CISO or COO who wants an accountable managed outcome rather than another console to staff and watch, that difference is the decision.
Vijilan vs Expel FAQ.
Is Vijilan cheaper than Expel?+
Neither company publishes dollar pricing, so compare structures. Expel deals are custom-quoted annual (often multi-year) enterprise subscriptions priced by integrated technologies, with onboarding fees and add-ons like threat hunting, managed phishing, and IR retainers commonly billed separately. Vijilan pricing is a predictable per-user/per-endpoint subscription, scoped through a consultation rather than published: ThreatLog SIEM is included in the service on an index-free engine, and hunting and active containment are in the base packages rather than add-ons. For most mid-market and enterprise scopes, the bundled model makes the all-in comparison simpler and often more favorable — run both quotes against your full stack cost, including the Splunk or Sentinel licensing Expel's model leaves in place.
Can Expel and Vijilan run together?+
There's rarely a reason to run both MDRs, but the more common coexistence question is with CrowdStrike: Expel MDR is commonly evaluated as an alternative to Falcon Complete, while Vijilan's NextDefend is explicitly built to complement it — Falcon Complete keeps the MDR role and Vijilan engineers and operates the Falcon Next-Gen SIEM. If you're an Expel customer adopting Falcon NG-SIEM, NextDefend can run the Falcon NG-SIEM engineering practice Expel's Managed SIEM (Sentinel and Splunk ES only) doesn't offer.
Can I migrate from Expel to Vijilan?+
Yes, and the path is low-friction because both models are vendor-agnostic. ThreatRespond wraps the EDR you already run — Defender, SentinelOne, Carbon Black, and others — with identity, cloud, and SaaS coverage across its six domains, so there's no rip-and-replace. If you're also retiring a Splunk or Sentinel bill, NextDefend runs a structured professional-services engagement to stand up Falcon Next-Gen SIEM on the LogScale engine — Cribl-managed ingestion, parsers, detections, and dashboards, hosted on AWS — then operates it 24/7. Time the switch around your Expel renewal (annual, often multi-year) to avoid paying twice during the transition.
Does Vijilan actually take response actions like Expel does?+
Yes — this is honest parity. Expel executes pre-approved remediations through your tools' APIs: containing hosts, disabling AD and Entra ID/Okta accounts, blocking hashes, removing malicious emails. Vijilan's ThreatContain does active containment from its 24/7 SOC — isolating hosts, disabling accounts, blocking IPs, killing processes, with sub-15-minute containment — before your phone rings. The differences are packaging and scope: Vijilan includes containment and proactive hunting (ThreatHunt) in ThreatRespond, where Expel sells hunting and full incident response as add-ons, and Expel's action scope is bounded by what your integrated tools expose via API.
