Additive Cyber Hardening
A stabilizing overlay that hardens the cybersecurity you already run — physics-enforced and geometry-locked. Nothing is replaced, so operations continue as threats are mitigated.
The Overlay
Sigma Shield™ is a stabilizing layer that hardens systems already running. It works as an additive overlay on your conventional cybersecurity, built on a physics-enforced, geometry-locked architecture.
Nothing is replaced — so downtime is significantly reduced and often eliminated, expensive recertifications aren’t triggered, and operations continue as the attack is mitigated.

Conventional hardening often means replacing systems, taking them offline, and re-certifying them. Sigma Shield™ takes a different path: it strengthens what is already in place.
Deploys as an overlay on your existing cybersecurity stack. No rip-and-replace, no new platform to stand up.
Downtime is significantly reduced and often eliminated. Operations continue while the attack is mitigated.
Because nothing underneath is replaced, expensive recertification cycles aren’t triggered.
Geometry-locked, physics-enforced stability — resilience grounded in physical principles, not software patches alone.
Where It Fits
Sigma Shield™ is designed for environments where staying online under pressure matters as much as the defense itself.
Hardening for mission systems and tactical networks that cannot afford to go dark.
Added resilience for operators who need continuity through an active threat.
Stability for unmanned and edge platforms operating beyond the reach of a data center.
Holds up where connectivity is intermittent, jammed, or denied.
Sigma Shield™ strengthens the systems you already trust, without the downtime and recertification that come with ripping them out. Let’s talk about your environment.
