CrowdStrike Falcon Prevent
Antivirus by behaviour and AI, not signatures — stopping malware, ransomware and fileless attacks the old model misses, on one lightweight cloud agent that extends to the whole Falcon platform.
How it’s rated
Full scoreboard ↓Quick answer
Falcon Prevent is CrowdStrike's next-gen antivirus — the endpoint floor the whole Falcon platform builds on. It replaces signature-based AV with AI and behavioural analysis that stop malware, ransomware and fileless attacks by what they DO, not by matching a known signature, so it catches novel and zero-day threats the old model misses. It runs on the single lightweight Falcon agent (no on-prem servers, no signature updates to push), streams telemetry to the cloud Threat Graph, and is cloud-managed from day one. It's the reason CrowdStrike led the shift from 'antivirus' to 'endpoint protection' — and the base every other Falcon module (EDR, identity, cloud) attaches to on the same agent.

Understand next-gen antivirus before you buy it
Most product pages skip this. We start here — so you buy a capability, not a buzzword.
What is next-gen antivirus?
Endpoint malware prevention that works by AI and behaviour, not signatures — so it catches novel, fileless and zero-day attacks the old model can’t.
Falcon Prevent is the category-leading NGAV, and the base the whole Falcon platform builds on.
Signature AV vs next-gen antivirus — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | Signature-based AV | Next-gen antivirus (Falcon) |
|---|---|---|
| The method | Match a known signature | AI + behaviour (IOAs) |
| Novel attacks | Missed until catalogued | Caught on behaviour |
| Fileless attacks | Invisible to file scanning | Detected by intent |
| The agent | Heavy, plus servers | One lightweight sensor |
| Updates | Constant signature pushes | Cloud-managed, no pushes |
| Infrastructure | On-prem management servers | Cloud-native, nothing to run |
| The intelligence | Your box, alone | Threat Graph network effect |
| The upgrade path | A new product for EDR | Same agent lights up EDR+ |
One agent deploys the NGAV base — and the same sensor lights up EDR and beyond with a licensing switch.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
The Single Agent
One small sensor doing NGAV — and ready to light up EDR, identity, data and more without a second agent. Deploy once, extend forever.
Machine-Learning Engine
AI models on the endpoint and in the cloud classify files and behaviour — catching malware that no signature has ever seen.
Behavioural IOAs
Detects the intent behind actions — the sequence that means 'ransomware' — rather than a known-bad hash, so novel attacks still get caught.
Threat Graph
Trillions of events across the customer base correlated in the cloud — one machine's novel attack becomes everyone's protection.
Cloud Management
Managed entirely from the cloud console — no on-prem servers, no signature distribution, no version sprawl to maintain.
One agent on every machine, one console over all of them — modules attach without a second operational world.
Twelve capabilities. Prevent, detect, operate.
Falcon Prevent catches what signatures can’t — and is the one-agent floor the whole Falcon platform builds on.
AI-Driven Prevention
Machine-learning models on the sensor and in the cloud classify files and processes — catching malware no signature has seen.
Behavioural IOAs
Indicators of attack detect the intent behind actions — the sequence that means ransomware — not a known-bad hash.
Fileless Attack Defence
Stops memory-only and script-based attacks that never write a file — invisible to signature scanning.
Ransomware Prevention
Behaviour-based blocking of encryption sequences — stops ransomware before it locks the estate.
Exploit Mitigation
Blocks the exploitation techniques attackers use to gain a foothold — technique-based, not sample-based.
Single Lightweight Agent
One sensor for NGAV — and ready to light up EDR, identity, data and cloud without a second agent.
Cloud-Native Management
Managed entirely from the cloud console — no on-prem servers, no signature distribution to maintain.
No Signature Updates
Because it isn't signature-based, there are no constant definition pushes to distribute and verify.
Threat Graph Intelligence
Trillions of events correlated in the cloud — one customer's novel attack becomes everyone's protection.
Rich Telemetry
Streams the endpoint activity that powers detection and — when EDR is enabled — full investigation.
Prevention Policy Control
Granular prevention policies, custom block/allow lists and sensor tuning for your environment.
The Platform Floor
The endpoint base every other Falcon module extends — deploy once, add capabilities as a switch.

Here’s what genuinely sets Falcon Prevent apart from the alternatives.
Signatures were always losing
A signature can only catch what's already been seen and catalogued — useless against a novel or fileless attack. Falcon Prevent classifies by behaviour and AI, so a never-before-seen ransomware strain gets stopped on what it tries to DO, not on whether it's in a database.
One agent, no server farm
Legacy AV meant management servers, signature distribution and version chaos. Falcon Prevent is one lightweight cloud-managed sensor — nothing on-prem to run, nothing to keep patched, and the same agent extends to EDR and beyond.
The base for the whole platform
Prevent isn't a dead-end AV — it's the floor. The same agent lights up Falcon Insight (EDR), Identity Protection, Data Protection and more with a switch, so your endpoint investment becomes a platform without redeployment.
The Threat Graph network effect
Every endpoint feeds the cloud Threat Graph — trillions of events correlated so one customer's novel attack becomes detection for all. Your protection improves from attacks you never even saw.
Proven at the top of the quadrant
Seven consecutive Gartner MQ EPP Leader placements — furthest right on Completeness of Vision — isn't marketing, it's the analyst consensus that the architecture and efficacy lead the category.
The honest scope
Prevent is NGAV — excellent, but it's the floor, not the whole platform. To get the visibility and response that stops a determined attacker (not just blocks known-bad), you want Falcon Insight XDR on top (its own page). Prevent alone is strong AV; Prevent + Insight is endpoint security. TechBag scopes the right mix.

Quick poll — what’s driving your evaluation?
Talk to an advisor“It caught a fileless attack that our old signature AV waved straight through. Behaviour-based prevention isn't a buzzword — it's the difference between blocked and breached.”
“One lightweight agent replaced a management server, a signature-distribution headache and three version conflicts. Deployment across 12,000 endpoints was genuinely painless.”
“We started with Prevent and flipped on EDR later — same agent, no redeployment. Buying the endpoint became buying a platform, exactly as promised.”
“The cloud console means nothing on-prem to run. Our small team manages endpoint security for the whole company without a dedicated server admin.”
“Prevention efficacy in our bake-off was the best we tested. It's premium-priced, and it earned it on catch rate.”
“It's NGAV — for full response you need Insight XDR on top. We knew that; just scope the mix so you're not surprised by the platform pricing.”
“The Threat Graph network effect is real — detections improve from attacks we never personally saw. That collective intelligence is a genuine edge.”
“Premium pricing is the honest catch. For us the efficacy and single-agent simplicity justified it; a pure budget buyer should compare Defender.”

What does a missed attack cost you?
Drag the sliders (count endpoints; IT-hour cost as loaded incident rate). Estimates assume ~2 hours per endpoint per year of AV management and missed-detection remediation on legacy signature AV, with ~70% removed by behaviour-based NGAV on one cloud agent — the avoided-breach value is the larger, unpriced win. Illustrative.
Loaded cost = salary + overheads per productive hour. Illustrative only — your TechBag quote models actual device counts and modules.

The 8 questions to ask every NGAV vendor
Take this into your next vendor call — including ours.
Test prevention against live and novel/fileless samples — behaviour-based catch rate is the whole point vs signatures.
Deploy on a pilot group and confirm it's one lightweight sensor with nothing on-prem — time the rollout.
Confirm the same agent lights up Insight XDR, identity and more — so today's endpoint buy is tomorrow's platform.
Plan the AV cutover per group — Prevent replaces it; sequence the removal to avoid a gap.
Review prevention policy and any custom blocklisting/allowlisting for your environment.
Understand the cloud intelligence network effect — detections improve from the whole customer base.
Decide Prevent alone (NGAV) vs Prevent + Insight (full endpoint security) — don't mistake the floor for the platform.
Model bundle vs Falcon Flex if you'll adopt more modules — TechBag runs it in INR/GST.
