Top Recommended Replacements
Cloudflare Zero Trust
FREEBest Prisma Access Replacement
Why we like it
Replaces the 'SASE' portion of Prisma; free for up to 50 users; includes ZTNA (VPN replacement), DNS filtering, and browser isolation; extremely easy to deploy.
Keep in mind
Does not secure cloud infrastructure (AWS/Azure) configuration like Prisma Cloud; purely for user access control.
Prowler
Best Prisma Cloud Replacement
Why we like it
The industry standard for open-source CSPM (Cloud Security Posture Management); runs over 240 security checks on AWS, Azure, and GCP to find misconfigurations for free.
Keep in mind
Command-line interface (CLI); provides the 'audit' data but doesn't have the automated 'fix' buttons found in Prisma Cloud.
Wazuh
Best Unified XDR Platform
Why we like it
A massive open-source platform that monitors endpoints, cloud workloads (AWS/Azure), and file integrity; the closest 'single pane of glass' alternative to Prisma's dashboard.
Keep in mind
Requires you to host your own management server; steeper learning curve than a SaaS product.
Twingate (Starter)
FREEBest VPN Replacement
Why we like it
Free for up to 5 users; replaces Prisma Access VPN with a modern 'Zero Trust' tunnel; hides your internal servers from the internet completely.
Keep in mind
The free tier is limited to 5 users; lacks the deep packet inspection (DPI) and malware filtering of Prisma Access.
Trivy (Aqua Security)
Best Container Scanner
Why we like it
Replaces 'Prisma Cloud Compute' (formerly Twistlock); scans containers, file systems, and git repositories for vulnerabilities (CVEs) and misconfigurations.
Keep in mind
A scanner tool, not a full runtime protection platform; requires integration into your CI/CD pipeline.
NetBird
Best Open Source SASE
Why we like it
Builds a private mesh network for your team using WireGuard; open-source alternative to Prisma's GlobalProtect; includes access controls and peer-to-peer encryption.
Keep in mind
Requires self-hosting for the 'unlimited' experience; less focus on 'Internet Threat Protection' compared to Cloudflare.
Falco
Best Runtime Security
Why we like it
The gold standard for Kubernetes threat detection; monitors system calls in real-time to detect anomalous behavior (like a shell opening in a container).
Keep in mind
Extremely technical; requires writing custom YAML rules to match the depth of Prisma's out-of-the-box policies.
pfSense Plus
FREEBest SD-WAN Alternative
Why we like it
Replaces the hardware firewalls and SD-WAN routing of Prisma; enterprise-grade packet filtering, VPN, and traffic shaping for $0 on your own hardware.
Keep in mind
It is a firewall OS, not a cloud service; you are responsible for the hardware maintenance.
CloudSploit (by Aqua)
Best Lightweight CSPM
Why we like it
Scans AWS, Azure, GCP, and OCI accounts for security risks; extremely fast and easy to run; generates HTML reports for compliance audits.
Keep in mind
Development has slowed slightly compared to Prowler; focuses mostly on 'Configuration' rather than deep threat detection.
DefectDojo
Best Vulnerability Dashboard
Why we like it
If you use multiple free tools (Prowler, Trivy, Nikto), DefectDojo acts as the central dashboard to view all findings in one place, mimicking the Prisma console.
Keep in mind
Does not scan anything itself; it is purely a management portal for other scanners.
Cilium (with Hubble)
Best K8s Network Security
Why we like it
Provides deep API-aware network security and visibility for Kubernetes; replaces Prisma's microsegmentation features using eBPF technology.
Keep in mind
High complexity; intended for DevOps engineers running large Kubernetes clusters.
Elastic Security (Basic)
FREEBest SIEM Integration
Why we like it
The Elastic Agent provides free malware prevention and collects cloud logs; allows you to build a custom 'Cloud SIEM' without paying for Cortex XDR.
Keep in mind
You need to host the Elastic Stack (ELK) to store the data, which can be resource-intensive.
