On February 24, 2025, Skybox Security went dark. No transition plan, no data export window, no gradual sunset. One day you had a firewall audit platform, the next day you didn't.
If you were one of the roughly 500 enterprise customers running Skybox, you already know what happened next: compliance evidence disappeared, audit trails evaporated, and the visibility you'd spent years building into your firewall estate vanished overnight.
What You Actually Lost
Skybox wasn't just a vulnerability scanner. Teams used it for firewall rule analysis, network topology modeling, compliance evidence generation, and policy change tracking. When it shut down, you lost:
- ✗ Continuous visibility into firewall rule hygiene across vendors
- ✗ Compliance evidence packages for audits (PCI-DSS, ISO 27001, SOC 2)
- ✗ Historical audit trail showing configuration drift over time
- ✗ Risk context tying firewall misconfigurations to actual exposure
- ✗ Multi-vendor normalization — one view across Palo Alto, Fortinet, Sophos, Check Point
What the Enterprise Alternatives Cost
The obvious move is to evaluate the usual suspects:
| Vendor | Annual Cost | Deployment |
|---|---|---|
| Tufin | $50K–$200K+ | Weeks–months |
| AlgoSec | $40K+ | Weeks–months |
| FireMon | Enterprise | 60+ days |
These are legitimate platforms. If your organization has the budget and timeline, evaluate them properly. But if you're a mid-market security team that just lost audit coverage and your next compliance review is in 90 days, spending six months on an enterprise RFP isn't realistic.
A Different Approach
CRWLR is a firewall audit platform built around a simple idea: upload a config file, get security findings in 60 seconds.
No agents to deploy. No infrastructure to provision. No professional services engagement. You export a config from your firewall management console, upload it to CRWLR, and get a structured analysis of your security posture.
What We Don't Do (Yet)
Transparency matters more than a feature checklist:
- No network topology modeling. We analyze individual firewall configs, not path analysis across your entire network.
- No automated remediation. We detect drift and tell you what changed; your team fixes it.
- No real-time monitoring. Audit-oriented with scheduled re-scans, not continuous.
- Six vendors today. Juniper SRX, Cisco Firepower (FTD), and others are not yet supported.
If topology modeling or automated remediation was core to your Skybox workflow, CRWLR alone won't replace that. But if what you primarily needed was firewall rule audit, compliance evidence, and security posture visibility — that's exactly what we built.
