What is Source Code Escrow?
A contractual arrangement where the vendor deposits source code with a neutral third party — the operator can claim it under defined trigger conditions (vendor bankruptcy, abandonment, etc.).
Also known as
Source Code Escrow — explained.
Source code escrow is a contractual arrangement where the vendor deposits the source code (and increasingly, the build pipeline, infrastructure-as-code, and operational runbooks) with a neutral third party. The operator can claim release of the deposit under defined trigger conditions — vendor bankruptcy, sustained breach of support obligations, abandonment of the product, acquisition by a competitor, or sale to a sanctioned entity. The escrow is most valuable when paired with verification — periodic third-party audits that the deposit actually builds and runs. Escrow is a routine procurement requirement for: government tenders, banking core-system contracts, healthcare critical-systems contracts, defence, and any engagement where the operator's continued operation depends on software a single small vendor produces. The Zeour default for enterprise engagements includes a documented escrow arrangement with quarterly verification, alongside the 90-day exit window that hands over operational control independently of the escrow trigger.

Sovereign Deployment
Sovereign DeploymentSoftware that runs entirely inside the operator's perimeter — their hardware, their network, their backups, their keys — with no third-party dependency for continued operation.
Fixed-Fee Engagement
Engagement ModelA delivery model where price is fixed per phase or per milestone — not time-and-materials — so the operator knows the cost before committing to the next stage.
Exit Window
Engagement ModelA defined post-engagement period — typically 90 days — during which the vendor supports the operator running the system independently before the contract ends.
Air-Gapped Deployment
Sovereign DeploymentA system deployed on a network with no physical or logical connection to the public internet — the strictest form of sovereign deployment.
BYOK (Bring Your Own Key)
Sovereign DeploymentA deployment model where the operator supplies and controls the encryption keys protecting their data — the vendor cannot decrypt without operator co-operation.
Data Residency
Sovereign DeploymentA requirement that personal or regulated data is stored, processed, and backed up within a defined jurisdiction — usually a country or a treaty bloc.
National Card Scheme
Sovereign DeploymentThe country-operated card-payment scheme that processes domestic transactions on sovereign rails — mada in KSA, KNET in Kuwait, OmanNet in Oman, the UAE national scheme in the Emirates.
National Identity Gateway
Sovereign DeploymentThe country-operated identity-federation surface citizens use to prove who they are to public + private services — typically over OIDC against a sovereign-hosted gateway.
