About Dispersive Stealth Networking

Dispersive Stealth Networking, from Dispersive Holdings, Inc., is a preemptive cybersecurity platform that makes data in motion invisible, resilient, and fully under an organization's control. Dispersive Stealth Networking secures the communication paths that connect users, applications, agents, models, and infrastructure. Dispersive is a software overlay that runs on the infrastructure an organization already operates.[4][6]

Dispersive Stealth Networking fragments traffic across dynamic, non-deterministic paths. Dispersive Stealth Networking hides data in motion by splitting, encrypting, and obfuscating traffic across multiple diverse network paths simultaneously. Data streams are split at the authenticated source and re-addressed with a Dispersive header, so that traffic follows different network paths based on instructions from the Dispersive Controller. The underlying IP networks deliver these packets to Dispersive software nodes known as Data Deflects. The authenticated destination reassembles the split packet streams and strips out the Dispersive header information before passing the original packet to the receiving application. Dispersive paths roll during transmission rather than failing over after a break. Dispersive runs over transport including internet, 5G, VSAT, MPLS, and cloud backbone.[1][4]

Each fragment in Dispersive Stealth Networking is protected with layered encryption, including the NIST-standardized post-quantum algorithms ML-KEM and ML-DSA. Dispersive Stealth Networking uses FIPS 140-3 validated cryptographic modules. Post-quantum protection in Dispersive Stealth Networking extends across the data plane and the control plane. Dispersive architecture aligns with NIST-approved post-quantum cryptographic standards, including ML-KEM.[1][4][6][7]

Dispersive Stealth Networking secures the AI communication layer directly, across the full stack. Dispersive uses TLS fingerprint mitigation so that sensitive traffic blends into ordinary web communications. URL filtering in Dispersive Stealth Networking gives operators control over which destinations agents, users, and applications can reach. Dispersive operates after authentication, on the transport plane, and determines how the resulting traffic moves. Dispersive extends zero trust and SASE controls instead of competing with them. Dispersive isolates sensitive applications, users, and devices within micro-segmented environments. Dispersive integrates with Okta, AD, Entra, and other identity providers to enforce access controls.[4][10][11]

DispersiveCloud is a hosted SaaS deployment and is SOC 2 Type II certified. DispersiveCloud runs on global cloud infrastructure from providers including Amazon Web Services and Azure. DispersiveFabric is the self-hosted deployment, built for larger, more complex environments, where the customer runs and controls every component. DispersiveFabric is a software-defined overlay network with a microservices architecture that deploys on public cloud, private cloud, containers, VMs, or dedicated hardware. Customers decide whether Dispersive hosts the control plane or their own team runs it. Some organizations use Dispersive to retire specific components, such as legacy VPN or SD-WAN.[4][12]

Trusted Cloud Edge (TCE) dynamically splits and secures traffic across multiple invisible paths. Trusted Cloud Edge (TCE) secures the underlying transport layer of a SASE stack. Trusted Cloud Edge (TCE) can augment or fully replace SD-WAN. Trusted Cloud Edge (TCE) offers software, virtual, container and hardware based gateways and endpoint software for remote users and data scientists.[5]

Dispersive uses path selection across fiber, cellular, satellite, and other transports to sustain mission applications through disconnected, denied, intermittent, and limited-bandwidth (DDIL) conditions. Dispersive offers a software-only gateway that deploys on mission-approved or customer-furnished hardware without proprietary appliance dependencies. Dispersive's adaptive communications architecture is fielded across five mission areas. Dispersive covers rapid, ephemeral coalition and mission-partner connections with fast provisioning and equally fast revocation. Select federal programs, including the Department of Homeland Security, rely on Dispersive to maintain mission-critical communications in contested, remote, or degraded environments.[6][7]

Financial services and other regulated institutions use Dispersive to secure sensitive data in motion across hybrid and multi-cloud environments. Dispersive Stealth Networking includes a production edge deployment with American Tower in collaboration with Vertical Data.[6][12]

Dispersive's core architecture originated in U.S. Department of Defense programs. Dispersive holds 53 granted patents covering multipath fragmentation, dynamic path selection, independent per-channel encryption, and stealth transport. Dispersive is an AWS ISV-A partner, available on the AWS Commercial Marketplace and the AWS IC Marketplace. Dispersive Stealth Networking is built on a multi-path, quantum-resilient architecture that is FIPS 140-3 compliant.[1][2][4][5][6][7][8][10][12]
