Least-privilege access
Access requests are limited to the defined work. Role-based and time-bound access is preferred when the customer environment supports it.
Security and data handling
Migration access should be limited, documented, and reversible
Microsoft migration projects can touch identity, content, mail, permissions, business processes, and sensitive data. Horton Scientific structures access and change work around least privilege, customer approval, validation, and a clear handoff.
Delivery principles
How access and change work are handled
The final process is aligned to the customer environment, contract, and security requirements. These principles guide the default delivery model.
Customer-owned data
Customer data remains customer data. Working files are limited to engagement needs and handled according to agreed retention and deletion requirements.
Approved delivery paths
Remote work is performed through customer-approved access methods, administration portals, migration tools, PowerShell, Microsoft Graph, and approved repositories.
Documented changes
Assumptions, commands, settings, validation outputs, and handoff notes are documented so customer administrators can understand the work.
Change control
Sensitive changes can be routed through customer tickets, approvals, named stakeholders, maintenance windows, and separation-of-duties requirements.
Access and staging cleanup
Closeout can include removal of temporary access, scripts, staging artifacts, service accounts, and migration tooling where applicable.
Procurement and access review
Practical documentation for the approval process
Security and procurement teams often need a clear description of access, change scope, data handling, and handoff before migration work begins.
- NDA or MSA support
- Access request list
- Change-control notes
- Migration runbooks
- Validation reports
- Administrative handoff documentation
Customer controls
The customer remains in control of production access
Horton Scientific can work inside established approval, ticketing, maintenance, logging, and review processes.
Before work begins
- Confirm named technical and business owners.
- Define approved access methods and required roles.
- Agree on change windows, approvals, logging, and validation.
- Document retention, deletion, and handoff expectations.
