SimIS CMS
Most websites are built by marketers.This one wasn’t.
One integrated, open-source platform with security in the foundation. We trust it enough to run our own.
Get in TouchWhy we built it
When SimIS needed a platform for its own websites and mobile apps, the available options shared a flaw: they depended on stacks of third-party plug-ins, and every plug-in is one more thing to patch, one more compatibility risk, one more way in for an attacker. As a company that builds software for defense customers, we weren’t willing to accept that.
So we built our own: one complete, integrated platform, engineered in-house and released as open source. SimIS CMS runs simisinc.com in production today, which means the platform on this page is not a demo. You’re looking at it.

Security is the point
Most CMS platforms outsource security to whoever wrote the plug-in. SimIS CMS ships it in the core:
- Modern password hashing (Argon2)
- Single sign-on via OAuth and OpenID Connect
- Request rate limiting
- IP firewall and geo-filtering
- Spam filtering and captcha
- Automated code security analysis in CI
And the source is public, so nothing is hidden: your security team, or ours, can read every line.
Run it yourself. Run it with us. Either way, it’s yours.
Download it, modify it, deploy it: SimIS CMS is Apache 2.0 licensed, no strings. What organizations hire SimIS for is everything around it: deployment and hosting on infrastructure we control, hardening and monitoring by the same team that delivers our cybersecurity and CMMC practice, content and design support, and a single accountable partner when something needs to be right.
If your organization operates anywhere near the defense industrial base, you already know why the company running your website matters.
