LightEDR vs SentinelOne Singularity - 2026
SentinelOne is known for its autonomous AI-driven response capabilities and Storyline technology, which builds a full attack story from correlated events. LightEDR is built for teams who want continuous Zero Trust verification, transparent pricing, and a minimal agent footprint. Here is where each platform fits.
Based on publicly available documentation as of May 2026.
Feature comparison
| Feature | LightEDR | SentinelOne Singularity |
|---|---|---|
| Agent footprint | < 40 MB | Varies by platform (typically 100-200 MB reported) |
| Zero Trust (continuous scoring) | Built in - NIST SP 800-207, 5 signals, continuous | Not native to the EDR layer |
| Pricing | From £5/agent/month - published publicly | Quote-only across all tiers |
| Multi-tenant | Native | Available via Singularity Hologram (add-on) |
| Autonomous response | Policy-driven containment (one-click or API) | ActiveEDR - autonomous kill, quarantine, rollback |
| Attack correlation | Process-tree forensics, 90-day telemetry | Storyline - full attack story across events |
| MITRE ATT&CK detection | Yes | Yes - strong coverage |
| Sigma rule support | Native | Not natively - custom STAR rules format |
| Linux (no kernel module) | eBPF-based, no kernel module | Kernel module required on some Linux distributions |
| AI-assisted triage | Bring-your-own LLM (5 providers) | Purple AI (available in higher tiers) |
| Ransomware rollback | Not included | Storyline Active Response includes rollback |
| Free tier | Free up to 5 agents, no card required | No publicly available free tier |
Where SentinelOne wins
SentinelOne's genuine strengths
- Autonomous response. SentinelOne's ActiveEDR can autonomously kill processes, quarantine endpoints, and roll back ransomware encryption - without requiring an analyst to approve each action. For teams who want the platform to act without human-in-the-loop, this is a meaningful differentiator.
- Storyline correlation. Singularity's Storyline technology automatically correlates events across a campaign into a single visual attack narrative. This significantly reduces the manual work of reconstructing an attack chain from raw log data.
- Ransomware rollback. The ability to roll back file changes made by ransomware is a capability specific to SentinelOne's Storyline Active Response. LightEDR does not offer this.
- Device discovery (Ranger). SentinelOne's Ranger module provides passive network discovery of unmanaged devices. Useful for teams who need visibility into their full asset inventory from a single console.
Where LightEDR wins
LightEDR's genuine advantages
- Zero Trust continuous scoring. SentinelOne does not offer continuous NIST SP 800-207 trust verification at the EDR layer. LightEDR's five-signal scoring, challenge-response every 5 minutes, and instant revocation address a threat model that SentinelOne's agent trust model does not.
- Agent footprint. The LightEDR agent is under 40 MB. SentinelOne's agent is larger on all platforms. For constrained environments - OT, VDI, or endpoints where performance budget is tight - this is a real operational difference.
- Pricing transparency. SentinelOne pricing is quote-only. LightEDR publishes £5/agent/month with no hidden multipliers. For MSSPs and budget-conscious teams, knowing what you will pay before calling sales matters.
- Sigma rules natively. LightEDR supports standard Sigma rules without translation. SentinelOne uses its own STAR rules format. If your detection engineering team writes in Sigma, LightEDR eliminates the translation step.
- No kernel module on Linux. eBPF-based telemetry means no kernel module, no reboot on deployment, and no compatibility issues across kernel versions.
Which to choose
Choose SentinelOne if:
- Autonomous response without human approval is a requirement
- Ransomware rollback is in your security requirements
- You want attack stories auto-correlated across campaigns
- Device discovery from the same console matters to you
Choose LightEDR if:
- Zero Trust continuous verification is a security or compliance requirement
- Agent footprint is a constraint (OT, VDI, low-power endpoints)
- Pricing transparency matters - you don't want a sales call to get a number
- Your detection team writes in Sigma and wants native support
- You want to use your own LLM for AI triage without another vendor add-on
