DatSov

DatSov is a British cyber security and data-sovereignty consultancy that trades under the legal entity ProSolve Ltd. The company is registered in England & Wales under company number 13955695, was incorporated on 4 March 2022, and operates from a registered office at 483 Green Lanes, London, N13 4BS. Its stated nature of business is information technology consultancy activities (SIC 62020). DatSov presents itself as "a sovereign infrastructure firm" that engineers sovereign infrastructure, secure communications and zero-knowledge data governance for organisations that require total ownership of their code and data. The brand's public positioning is built around the idea of "Sovereign Infrastructure. Total Ownership." Rather than selling generic IT consulting, DatSov frames its work as a stack of modules — private infrastructure, encrypted communications and zero-knowledge data governance — that clients own outright at every layer. The company says it publishes live build status for the stack, showing what is running, what is being built and what is pending. Its marketing emphasises borderless execution, zero-knowledge architecture, end-to-end encryption, EU/US sovereignty, SOC 2 alignment and a single technical lead model. DatSov's most visible product is the Sovereign Phone, a hardened smartphone offering. The Sovereign Phone is described as hardened Pixel hardware running a relocked, attestable GrapheneOS installation, with zero-knowledge encrypted communications and a number-less, data-only identity. DatSov sells the phone in three editions — Core, Shielded and a further tier — which it describes as a price and specification ladder rather than a security ladder, because the hardening is the same across all editions. The Core edition is listed at $2,200 with a $60 per month DatSov Secure Service fee after year one, based on a Pixel 10a; the Shielded edition is listed at $4,200 with a $90 per month fee after year one, based on a Pixel 10, and adds a rear-camera slide-cover case and priority support. DatSov states that every edition ships as a relocked, attestable GrapheneOS install that customers can independently verify, and it openly names two residual risks — hardware supply chain and physical coercion — arguing that anyone selling "unhackable" security is lying. Beyond hardware, DatSov describes a broader sovereign stack that includes a Sovereign VPN (multi-hop encrypted routing) and Sovereign VoIP, alongside encrypted communications and zero-knowledge data governance services. The company's operating model is unusual in its emphasis on accountability and ownership: every engagement runs through a single Dedicated Technical Lead who owns the outcome end to end, fixed prices are published where possible, and clients are said to leave every engagement owning the code, the data and the decision record. DatSov frames this as building capability rather than dependency, and stresses that strategy and security are never separate workstreams. DatSov is a private company, not listed on any stock exchange, and it positions its UK Companies House record — rather than a founder personality — as its trust anchor. The company operates in and markets to the United Kingdom, the European Union and the United States, and its brand identity is closely tied to the themes of digital sovereignty, verifiable security and data ownership.

DatSov is the trading brand of ProSolve Ltd, a private limited company incorporated in England & Wales on 4 March 2022 under company number 13955695. The company's registered office is at 483 Green Lanes, London, N13 4BS, and its registered nature of business is information technology consultancy activities (SIC code 62020). From its inception the business has been positioned in the cyber security and data-sovereignty space rather than as a general IT consultancy. DatSov describes itself as "a sovereign infrastructure firm" and says it engineers sovereign infrastructure, secure communications and zero-knowledge data governance for organisations that require total ownership of their code and data. Its public materials present the company as building a modular "sovereign stack" in the open, with live build status showing what is running, what is being built and what is pending. The stack includes a Sovereign VPN with multi-hop encrypted routing, Sovereign VoIP, encrypted communications and zero-knowledge data governance. The company's most prominent product is the Sovereign Phone, a hardened smartphone offering built on Google Pixel hardware running a relocked, attestable GrapheneOS installation. DatSov sells the phone in editions — Core, Shielded and a further tier — which it describes as a price and specification ladder rather than a security ladder, because the hardening is identical across editions. The Core edition is listed at $2,200 with a $60 per month DatSov Secure Service fee after year one, based on a Pixel 10a; the Shielded edition is listed at $4,200 with a $90 per month fee after year one, based on a Pixel 10, and adds a rear-camera slide-cover case and priority support. DatSov states that every edition ships as a relocked, attestable GrapheneOS install that customers can independently verify, and it openly names two residual risks — hardware supply chain and physical coercion — arguing that anyone selling "unhackable" security is lying. DatSov's operating model emphasises accountability and ownership. Every engagement runs through a single Dedicated Technical Lead who owns the outcome end to end, with no handoffs or diffusion of responsibility. Where a service can carry a fixed price, DatSov publishes it on the site; work priced on application is scoped in a mandatory architecture consultation before anything is configured. Clients are said to leave every engagement owning the code, the data and the decision record, which DatSov frames as building capability rather than dependency. Strategy and security are treated as a single workstream, with every recommendation stress-tested against the client's real threat surface. The company markets to the United Kingdom, the European Union and the United States, and highlights borderless execution, zero-knowledge architecture, end-to-end encryption, EU/US sovereignty and SOC 2 alignment. DatSov is a private company and is not listed on any stock exchange. It positions its UK Companies House record — rather than a founder personality — as its trust anchor, stating that the record is the basis of its accountability.
