ThreatRespond vs ThreatDefend: Which Vijilan Managed SOC Service Fits
ThreatRespond and ThreatDefend are both 24/7 managed SOC services from Vijilan, run by the same analyst team. The difference is who owns the security tools — and that ownership decides whose stack the SOC acts on and when full identity protection (ITDR) is included. On both, the SOC acts from the Essential tier.
ThreatRespond™ and ThreatDefend™ are both 24/7 managed SOC services from Vijilan, staffed by the same analysts and covering the same security domains. The difference is who owns the security tools — you do, or Vijilan does — and that ownership decides whose stack the SOC acts on and when full identity protection (ITDR) is included. On both, the SOC acts from the Essential tier.

What is ThreatRespond?
ThreatRespond is Vijilan's vendor-agnostic managed SOC service. It works with the security tools an organization has already standardized on — SentinelOne, Microsoft Defender, Carbon Black, Fortinet, Palo Alto Cortex XDR and others — rather than replacing them.
The SOC monitors those tools 24/7 across endpoint, identity, network, cloud, application and data. Tier 1 through Tier 3 analysts review every alert. Confirmed incidents come back with a guided remediation runbook, and priority alerts flow into your service desk through bi-directional PSA ticketing (ConnectWise, Autotask, Jira, Zendesk).
The buyer for ThreatRespond has already spent the money on tooling and does not want to spend it again. They are renting the expertise, not the software.
What is ThreatDefend?
ThreatDefend is Vijilan's fully managed service, where Vijilan brings the stack as well as the SOC. It runs on CrowdStrike Falcon EDR/XDR, deployed by Vijilan, with identity threat detection and response (ITDR) included from the entry tier.
It covers everything ThreatRespond does, and adds what follows from Vijilan owning the tooling: active containment — host isolation, account disable, token revoke, process kill — from the first tier up, and incident lifecycle ownership through to a forensics report.
The buyer for ThreatDefend wants the whole problem handled, including procurement of the tools.
What is the actual difference between them?
The SOC is the same. The coverage is the same. The difference is who owns the tools, and how early the SOC starts acting on them.
Both services run the same four tiers: Essential, Advanced, Premium and Elite. On both services the SOC contains incidents from the Essential tier, under a runbook you approve during onboarding.
With ThreatDefend, Vijilan owns the stack, and the SOC contains from the Essential tier and at every tier above it. With ThreatRespond, the tools are yours, and the SOC acts on them from the Essential tier too, under a runbook you approve in advance and with access you grant during onboarding.
That is a capability line, not a service-quality line. An organization with a capable internal IT team and a strong existing stack often gets more value from ThreatRespond. An organization whose realistic alternative is "the alert waits until Monday" needs the service that acts, at the tier where it acts.

Which one should we choose?
Answer one question: do you intend to keep the security tools you have?
Choose ThreatRespond if:
- You have standardized on an EDR, firewall and IAM you are happy with, and replacing them is not on the table.
- You want the SOC to act on the tools you already own, on every tier, and hand your team a cleanup runbook afterwards.
- You are consolidating vendors on the services side rather than the tooling side.
- Contractual or regulatory constraints tie you to a specific security vendor.
Choose ThreatDefend if:
- You are buying or renewing EDR anyway, and would rather have it operated than own the operating problem.
- There is no one reliably available at 3am to act on an escalation, and you want containment included at the entry tier.
- You want a single accountable party for detection, containment and the post-incident report.
- You are already on CrowdStrike Falcon, or moving there.
Can one organization run both?
No — the rule is one product per environment. An environment runs ThreatRespond or ThreatDefend, never both at once, because the two services make opposite assumptions about who owns the endpoint agent.
Genuinely separate environments are scoped separately, which is how a single company can end up with both: an acquired business already running a different EDR can stay on ThreatRespond while the parent estate runs ThreatDefend, rather than forcing a migration on day one.
Can you switch from one to the other?
Yes, and ThreatRespond to ThreatDefend is the common direction. Organizations frequently start with ThreatRespond because it requires no procurement cycle and no agent replacement, then move to ThreatDefend at their next EDR renewal, when the tooling decision is open anyway.
The reverse happens too, usually after an acquisition brings in an estate that is not worth migrating.
Who decides when the SOC acts?
A human does, on both services. The escalation path is the same either way, and an analyst reviews every alert before it reaches you. Automation is what removes latency from triage; a Vijilan analyst authorizes consequential action. The SOC is never autonomous-only.
That is the part worth checking with any managed SOC provider, because it is where "AI-powered" claims and operational reality tend to diverge.
What if neither fits?
Neither is the right question if your problem is a CrowdStrike Falcon Next-Gen SIEM deployment that needs engineering and operating rather than an MDR tier. That is NextDefend™, delivered as Deploy · Sustain · Operate, and it sits on a different axis from these two: it is about ingest, parsing, detection content and remediation across the whole environment rather than a managed tier over an endpoint stack.
Frequently asked questions
Is ThreatRespond just alerting? No. On every tier, analysts investigate to a conclusion, contain the threat on your tools under a runbook you approved in advance, and hand over a specific remediation runbook for the cleanup. The distinction from ThreatDefend is whose stack the SOC works on, not whether it acts.
When does the SOC start containing incidents? On both, from the Essential tier and every tier above it. With ThreatRespond the tools belong to you, so the SOC acts under a runbook you approve and with access you grant during onboarding.
Does ThreatDefend require us to remove our current EDR? Yes, on endpoint and identity. ThreatDefend runs on CrowdStrike Falcon. If removing your EDR is not acceptable, ThreatRespond is the service that fits.
Do both cover more than endpoints? Yes. Both cover endpoint, identity, network, cloud, application and data. Endpoint-only MDR is a common category of competitor; neither Vijilan service is limited that way.
Can one client run both services at once? No. One product per environment. Separate environments are scoped separately, so a company with an acquired estate on a different EDR can run one service on each.
Can an organization buy these directly, or only through a partner? Both. Vijilan reaches customers through MSP and MSSP partners, through VARs and distributors, and directly for mid-market and enterprise buyers. Partners have a standing commitment that Vijilan never competes with them for their clients.
How does ThreatDefend relate to CrowdStrike Falcon Complete? Falcon Complete is CrowdStrike's own managed service for Falcon, and Vijilan works alongside it rather than against it. ThreatDefend is Vijilan's own 24/7 SOC operating Falcon as one accountable service across endpoint, identity, network, cloud, application and data. If the question is specifically about extending detection and containment past the endpoint agent on a Falcon Next-Gen SIEM deployment, that is NextDefend Operate rather than either service here.
What does it cost? Both are priced per asset per month: endpoints, users, servers and firewalls are each priced as assets, cloud and identity sources such as Microsoft 365 are priced per user, and volume discounts apply across a partner's whole book. Vijilan does not publish rates — the pricing page is a short qualification step that routes you to verified pricing for your organization.
