About Quantum Logic Systems

We build the EFA family — pragmatic, transparent products that protect business email and the data behind it.

EFA — Complete. Secure. Connected.

Who we are

Quantum Logic Systems, LLC is a software company headquartered in Las Vegas, Nevada. We design and operate the EFA family of products — five complementary tools focused on the everyday reality of running a small or mid-sized business: keeping email safe, recoverable, monitored, archived, and accessible.

We started OpenEFA because the existing email security market was opaque, overpriced, and hostile to the people who actually have to live with it. The same philosophy carries across the rest of the family: clear pricing, clear filtering decisions, clear support — from people you can reach.

What we believe

  • Open is a habit, not a marketing word. We tell you why a message was blocked, why a backup failed, why an alert fired. No black boxes.
  • AI is a tool, not the product. We use machine learning where it improves accuracy. We use plain rules where they're better. The product is the outcome, not the buzzword.
  • Small and mid-sized businesses deserve the same protection as enterprises. Without enterprise pricing or enterprise complexity.
  • Support is a person. When something matters, you get a human, not a ticket queue.
