Best Alternatives to ThreatLocker
ThreatLocker’s Zero Trust allowlisting and ringfencing model is unique. Teams typically switch for these reasons:
- Want traditional EDR/XDR instead of allowlisting-first
- Need transparent per-endpoint pricing instead of quotes
- Prefer autonomous detection over ongoing tuning
- Seek bundled solutions (EDR + threat intel + identity)
| Alternative | Best For | Starting Price | Key Difference |
|---|---|---|---|
| SentinelOne Singularity | Autonomous AI-driven EDR/XDR | $69.99/yr per endpoint | Top autonomous detection; rollback remediation; Complete tier needed for full EDR |
| CrowdStrike Falcon | Cloud-native EDR + threat intel | $59.99/yr per device | Elite threat intelligence and lightweight agent; modular pricing climbs |
| Bitdefender GravityZone | Strong AV at fair price | ~$77/yr per device | Excellent independent test scores; EDR is higher tier; good MSP program |
| Microsoft Defender for Business | M365 ecosystem teams | $3/mo per user | Cheap if you have M365; per-user covers multiple devices; best within Microsoft |
| Sophos Intercept X | EDR + optional MDR | Quote | Strong anti-ransomware; easy MDR upgrade; Central console |
| ESET PROTECT | Lightweight, reliable protection | Quote | Very light agent; flexible deployment; lower resource use |
| Webroot Business Endpoint Protection | Ultra-light MSP deployments | Quote | Tiny fast agent; journaling/rollback; lighter EDR depth |
Why Teams Leave ThreatLocker
Allowlisting fatigue. ThreatLocker’s power requires ongoing tuning as new software deploys. Teams tired of whitelisting requests migrate to SentinelOne or CrowdStrike for passive detection.
Pricing opacity. Quote-based models frustrate procurement. Microsoft Defender for Business ($3/user/mo) and SentinelOne ($69.99/yr) offer clarity.
Different workflow. MSPs running traditional AV+EDR stacks find ThreatLocker’s control model orthogonal. They consolidate to Bitdefender or Sophos instead.
EDR gap. If ringfencing alone isn’t enough, teams need EDR investigation. CrowdStrike Falcon Enterprise ($184.99/yr) or SentinelOne Complete ($179.99/yr) fill that need.
Our Take
ThreatLocker excels at preventing execution. If your threat model is “stop unauthorized software running,” stay. If you need detection, investigation, and response, pick SentinelOne (best autonomous) or CrowdStrike (best analyst tools).
