Zero Trust Software-Defined Perimeter With Dynamic Encryption

Aerobyte Cyber Defense is a zero trust security company founded in 2020 by Howard Hellman, who serves as chief executive, and partner Bill Tabor, whose background is in distributed Unix computing and IT security. The company is based in Tampa, Florida. It sells to government agencies, financial institutions, utilities, large technology OEMs, and enterprises running a mix of legacy plant and modern cloud services. Its public website did not return live content during research for this profile, so current status could not be confirmed.

The product is the Cyber Defense Framework, which virtualizes networking, security, and routing functions onto a single unified infrastructure layer and implements a software-defined perimeter on top of it. Connections between endpoints and servers are established through dynamic encryption tunneling rather than exposed network routes, so resources stay unreachable until access is granted. The framework covers five areas: identity verification, endpoints, data in motion, data at rest, and user behavior, and it deliberately moves away from usernames and passwords as the anchor of trust.

Aerobyte positions the framework as an open API ecosystem, so customers can attach third-party security products rather than replace their existing stack. The company emphasizes that the layer can be applied over legacy network infrastructure as well as cloud environments and connected device estates, allowing side-by-side testing against the existing setup before cutover. Products reached market in 2022, and Enterprise Security Magazine named the company among its zero trust security solution providers in 2021.
