Sysdig Secure vs Lacework: Cloud Workload Protection Honest Verdict (2026)

If you live and die by Kubernetes runtime signal and trust kernel-level introspection, Sysdig Secure is the stronger pick. If your cloud estate is broad, agentless-first matters, and you want behavior-based anomaly detection across the whole control plane, Lacework (now FortiCNAPP) is the stronger pick — with one big caveat: the Fortinet acquisition.

Quick Verdict

Sysdig Secure: deep runtime detection via Falco/eBPF, strong Kubernetes story, agent-required for full signal.
Lacework / FortiCNAPP: Polygraph behavior analytics, agentless-first cloud control-plane coverage, post-acquisition roadmap is the open question.
Tie-breaker: Kubernetes-first / regulated runtime requirements → Sysdig. Broad multi-cloud / agentless preference → Lacework (validate Fortinet roadmap first).

Side-by-side: where the real differences are

Dimension	Sysdig Secure	Lacework (FortiCNAPP)
Core detection engine	Falco (OSS, syscall-level, eBPF/kmod)	Polygraph (behavior graph + anomaly detection)
Primary signal	Kernel/syscalls + Kubernetes audit	Cloud control-plane + workload metadata + optional agent
Agent model	Required for full runtime visibility	Agentless-first, optional agent for workload depth
Kubernetes depth	Strong — Sysdig created Falco/CNCF	Solid — covers K8s audit, posture, behavior
Cloud control plane (AWS/GCP/Azure)	Supported, paired with runtime focus	Core strength — CSPM and identity behavior built in
Vulnerability management	Image, host, in-use exposure prioritization	Image, host, registry + active-package context
Attack-path / posture analysis	Yes, plus runtime-validated risk	Yes, via Polygraph relationship graph
Open-source foundation	Falco (CNCF graduated)	Proprietary
Corporate status (2026)	Independent, Goldman/Insight-backed	Owned by Fortinet, rebranding as FortiCNAPP
Best fit team	Container/K8s-heavy SOC, Linux-fluent SRE	Multi-cloud SOC, agentless preference, smaller security team

Operator-honest note: Both vendors will claim full CNAPP coverage (CSPM + CWPP + CIEM + KSPM + vuln + runtime). They both genuinely cover that surface area — the honest difference is depth per pillar and which signal you trust most. Sysdig was born from runtime depth and grew outward. Lacework was born from cloud-graph analytics and grew downward. Pick the one whose strongest pillar matches what you'll lose the most sleep over.

Where Sysdig Secure wins

Runtime detection depth. Falco/eBPF syscall signal catches things metadata-only tools cannot see — in-container crypto miners, runtime privilege escalation, drift from image.
Kubernetes-first DNA. Sysdig created Falco and donated it to the CNCF. The K8s audit and runtime story feels native, not bolted on.
In-use vulnerability prioritization. Tying CVE presence to runtime "is this package actually loaded?" signal cuts noise hard.
Open-source escape hatch. If commercial relationship sours, Falco itself is free and self-hostable — rare in this category.

Where Lacework (FortiCNAPP) wins

Polygraph behavior modeling. Composite behavior baselining across users, machines, and processes is a real differentiator for anomaly detection that doesn't depend on rule authoring.
Agentless cloud coverage. If you have hundreds of accounts and getting agents on every workload is politically expensive, agentless-first onboards faster.
Lower analyst rule-writing burden. Behavior-graph alerts trade some specificity for less detection-engineering overhead.
Fortinet ecosystem. If you already run Fortinet firewalls, FortiEDR, FortiSIEM, the FortiCNAPP integration story will get tighter over time.

What the marketing pages won't tell you

1. Agentless is not "no agent"

Lacework's agentless story covers cloud control plane and cloud workload metadata extremely well, but for full runtime visibility on Linux/K8s hosts it still recommends an agent. The "agentless" framing is marketing-true and operationally partial. Sysdig is honest that runtime needs an agent.

2. The Fortinet acquisition is a real evaluation variable

Acquisitions in this category historically have a 12-24 month re-platforming tail. Ask FortiCNAPP for roadmap commitments in writing, SLA continuity for standalone customers, and whether your renewal pricing is locked. This is not a hypothetical — it's the standard playbook.

3. CNAPP "coverage" is a checkbox war

Both tools tick every CNAPP pillar. The honest evaluation is to run a 30-day POC with your top 3 attack scenarios (cryptominer in a pod, exposed S3 bucket with sensitive data, IAM lateral movement) and see which one surfaces them faster and with less noise.

4. Cost models are not directly comparable

Sysdig tends to price on resources (nodes/cores/containers + workloads). Lacework prices more on cloud accounts + workload count. At the same environment size, quotes can vary by 30%+ in either direction. Normalize against your actual asset count, not the spec sheet.

FAQ

Is Sysdig Secure better than Lacework for Kubernetes?

For deep runtime visibility in Kubernetes, usually yes — Sysdig is built on Falco and instruments syscalls via eBPF/kernel. Lacework covers Kubernetes but leans more on metadata and behavior analytics than syscall-level introspection.

Did Fortinet buying Lacework change the product?

Fortinet acquired Lacework in 2024 and is rebranding it as FortiCNAPP. Core Polygraph and behavior detection continue. Long-term direction is platform consolidation inside Fortinet Security Fabric. Ask for roadmap commitments before signing in 2026.

Can either tool replace my SIEM?

No. Both are CNAPP/CWPP tools focused on cloud workloads and cloud control plane. They forward detections to your SIEM — they don't replace log retention, identity correlation across non-cloud, or compliance evidence aggregation.

Which one has the lighter agent footprint?

Lacework historically positions agentless-first with an optional Linux agent. Sysdig requires an agent for full runtime signal. Lacework feels lighter at install; Sysdig pays the agent cost to get deeper signal.

Is Falco the same as Sysdig Secure?

Falco is the open-source runtime engine Sysdig created and donated to CNCF — free and self-managed. Sysdig Secure wraps Falco with managed control plane, curated rules, vuln management, posture, and analyst UI. You can run Falco alone but lose the SaaS-managed experience.

The SideGuy take

The CNAPP category is consolidating fast, and the marketing pages all look the same. The right move is to pick the strongest pillar that matches your top risk, ignore the rest of the matrix, and pressure-test the vendor on roadmap stability — especially after the Lacework/Fortinet deal.
