Zscaler vs CrowdStrike: Different Layers, and Where an On-Device SWG Fits

Zscaler vs CrowdStrike: Different Layers, and Where an On-Device SWG Fits

Quick answer: Zscaler and CrowdStrike aren't competitors in the way most comparison searches assume. CrowdStrike Falcon protects the endpoint itself: processes, files, identities, and threats running on the device. Zscaler protects the traffic: web, SaaS, and private app access through its cloud. Most enterprises run both, and the two vendors publicly partner and integrate. The real question isn't Zscaler or CrowdStrike. It's how your web security layer should sit next to your EDR.

If you landed here weighing one against the other, here's the short version: you probably need an EDR and a secure web gateway. This post explains why, what the Zscaler and CrowdStrike integration actually does, and where an on-device SWG changes the picture.

Two different jobs: EDR vs SSE

EDR watches what happens on the device. SSE controls where the device goes and what data leaves with it.

Endpoint detection and response (EDR), which is CrowdStrike's core business, runs an agent on each laptop and server. It watches process behavior, catches malware and attacker techniques, and lets your SOC investigate and contain a compromised machine. CrowdStrike describes its Falcon platform as protecting endpoints, cloud workloads, identity, and data with a single lightweight-agent architecture.

Security service edge (SSE), which is Zscaler's core business, controls network access. A secure web gateway filters URLs, inspects SSL traffic, enforces cloud app policy, and runs DLP on uploads. Zscaler delivers this from its cloud: traffic is forwarded from the device to a Zscaler data center for inspection. For the full picture of how Zscaler works, see what is Zscaler, and for where it sits in the SASE world, is Zscaler SASE or SSE.

How the Zscaler and CrowdStrike integration works

Zscaler and CrowdStrike have an official partnership, and it's mostly about sharing signals. Here's what the vendors document on Zscaler's CrowdStrike partner page and in their September 17, 2024 joint announcement:

  • Adaptive access from device health. Zscaler's ZIA and ZPA can use CrowdStrike device health and active incident signals to adjust access policy. A compromised or unhealthy device gets less access.
  • Threat intelligence sharing. CrowdStrike threat intel feeds into the customer's Zscaler tenant, and Zscaler shares logs with CrowdStrike for cross-platform visibility.
  • Zero-day response. Zscaler's Cloud Sandbox detects an unknown file, correlates with CrowdStrike telemetry to find affected devices, and can trigger a cross-platform quarantine workflow.
  • SOC workflows. CrowdStrike Falcon Insight XDR uses ZIA and ZPA telemetry, and the Falcon Foundry Zscaler app connects Zscaler to CrowdStrike Falcon Next-Gen SIEM for threat sharing and custom SOAR workflows.

That's a real integration, and plenty of large enterprises use it. Notice what it doesn't change, though: your web traffic still detours through Zscaler's cloud to be inspected. The integration makes the two layers talk. It doesn't change the architecture of the SWG layer.

Where an on-device SWG fits next to your EDR

If your EDR already runs on the device, it's worth asking why your web security doesn't.

dope.security puts the secure web gateway on the endpoint. SSL inspection, URL filtering, Cloud Application Control, and Dopamine DLP all run locally on Mac and Windows, in under 100 MB of RAM. Traffic goes straight to its destination. That's Fly Direct.

What that means in a stack that already has an EDR:

  • Clear division of labor. Your EDR handles what runs on the device. dope.security handles where the device goes, what account it uses, and what data leaves.
  • No cloud detour. Web and SaaS sessions aren't routed through a vendor data center, which is up to 4x faster than legacy cloud-proxy SWGs.
  • Policy that follows the user. Enforcement runs on the device on any network, and policy lands on every endpoint in under a minute.
  • Events in your SIEM. dope.security streams web, AI, and data-movement events to your SIEM, so your SOC sees them next to endpoint alerts.

To be clear about scope: dope.security is not an EDR and doesn't replace CrowdStrike. It replaces the cloud SWG. If you're evaluating that swap, start with our best Zscaler alternatives shortlist or the head-to-head Zscaler vs dope.security.

Frequently asked questions

Is Zscaler a competitor to CrowdStrike?

Not directly. CrowdStrike is primarily endpoint protection and EDR. Zscaler is primarily cloud-delivered network security (SSE). The two companies partner and integrate rather than compete head-to-head.

Do I need both Zscaler and CrowdStrike?

You need an EDR and a secure web gateway. CrowdStrike can fill the EDR role. The SWG role can be filled by Zscaler or by an on-device SWG like dope.security.

What does the Zscaler CrowdStrike integration do?

It lets Zscaler use CrowdStrike device health and incident signals in access policy, shares threat intelligence and logs between the platforms, and connects Zscaler to CrowdStrike's XDR and Next-Gen SIEM for coordinated response.

Can dope.security replace CrowdStrike?

No. dope.security is a secure web gateway with DLP, CASB, and SSPM. It replaces a cloud-proxy SWG like Zscaler ZIA, not your endpoint protection.
