Where RANCID and Oxidized Fall Short
RANCID
RANCID (Really Awful Nasty Cisco config Differ) was the original network config backup tool, built in the early 2000s. It relies on Perl, Expect scripts, and CVS or SVN for version control. While it pioneered the space, its age shows:
- Complex setup — requires configuring Expect, CVS/SVN, cron jobs, and
.cloginrcfiles manually. - No web interface — diffs are viewed through command-line tools or third-party frontends like ViewVC.
- No secret handling — passwords and keys are stored in plain text in your version control system.
- Fragile scripting — Expect-based device interaction breaks easily with firmware changes or unexpected prompts.
Oxidized
Oxidized is the modern open-source successor to RANCID. It uses Ruby and Git, supports many more device types, and is significantly easier to configure. However, it still has gaps:
- No secret redaction — configurations are stored as-is unless you write custom hooks.
- No encryption — backups sit unencrypted in Git repositories on disk.
- DIY diffing — you get Git diffs, but no purpose-built visual interface for reviewing network changes.
- Self-managed infrastructure — you’re responsible for the server, backups of the backups, access control, and uptime.
- No SSO — user management is manual and basic.
What IronDiff Does Differently
IronDiff was purpose-built for MSPs and network teams who need configuration backup to be secure by default and zero-maintenance.
Security is Not an Afterthought
Every configuration is run through a vendor-aware redaction engine before it ever leaves your network. Optionally, raw backups are encrypted with post-quantum zero-knowledge encryption — meaning even IronDiff cannot read your data.
Deploy in Minutes, Not Hours
A single docker run command gets you up and running. No Ruby gems, no Perl modules, no CVS repositories, no cron jobs to manage. Auto-updates keep your agent current without intervention.
Diffs That Actually Make Sense
IronDiff's cloud portal shows you a clean, visual red/green diff of exactly what changed — not a raw Git diff buried in a terminal. Your whole team can see changes without needing SSH access to a server.
