Executive summary
Sudan is a conflict environment in which the principal risk to international organisations is not incidental violence but deliberate constraint: denial of movement, obstruction of clearance, interference with communications and the politicisation of humanitarian access.
The country has effectively fragmented into distinct control zones with different authorities, different documentation requirements and different tolerance for international presence. A single national access strategy will fail; an assessment written to control-zone level will not.
This brief is written for security managers, country directors and continuity planners who must make deployment, remote-management and suspension decisions with incomplete and rapidly ageing information.

Full report
Conflict geography
Sudan should be read as a set of control zones rather than a national map. Each zone has an authority that issues or withholds permission, a set of intermediaries who determine practical access, and a supply geography that constrains what can be moved and when. Analysis that stops at the national level produces plans that cannot be executed.
Frontline areas are characterised by shifting control, indirect fire and unexploded ordnance contamination. Rear areas are characterised by administrative constraint, surveillance of international staff and economic predation at checkpoints. Both require controls; they are not the same controls.
Access and humanitarian operating environment
Access is negotiated continuously and expires quickly. Written authorisations should be re-validated before every movement, not filed as evidence of permission. Organisations should maintain a live access log recording issuing authority, validity period, named signatory and the route or locality covered.
Remote management and national-staff-led delivery are the default operating models in high-constraint zones. Where risk is transferred to national staff or partners, it must be compensated: hazard provisions, insurance verification, communications equipment, evacuation eligibility and equal access to medical support are duty-of-care obligations, not programme costs to be trimmed.

Duty of care and staff safety
Priorities are unambiguous: verified medical and evacuation arrangements before deployment; hardened accommodation with standoff and a defined safe room; redundant communications including satellite; a documented relocation and hibernation plan with trigger criteria; and pre-agreed authority to suspend without headquarters consultation.
Detention and questioning of international and national staff is a realistic scenario. Organisations should hold a written detention response protocol, a named legal contact in-country and a communications policy that avoids escalating exposure through public statements.
Continuity and supply chain
Fuel, cash, connectivity and clearance are the four continuity dependencies that fail first. Cash management in a constrained banking environment carries its own security exposure and should be planned as a distinct risk line with dual control, low holdings and varied delivery patterns.
Dual-source every critical input and pre-position stock where storage risk is acceptable. Assume a two-to-six-week disruption window when modelling programme continuity.

Indicators and warnings
Escalation indicators: renewed offensive activity around urban centres or supply corridors; abrupt tightening of travel permit issuance; sustained connectivity blackouts; expulsion or visa refusal affecting international agencies; movement of forces towards previously quiet localities.
De-escalation indicators: functioning local cessation arrangements that survive more than one cycle; reopening of a major crossing or airfield to humanitarian traffic; measurable reduction in checkpoint extraction on a main corridor.
Outlook to 2027
Most likely: continued fragmentation with negotiated, localised and reversible access. Programmes should be designed to scale up and down within weeks rather than to run continuously.
Alternative: a broader negotiated settlement producing rapid access expansion. Organisations should hold a readiness plan for this scenario, pre-cleared staffing, framework supplier agreements and rapid assessment capacity, because the constraint in that case becomes speed, not permission.

Key findings
- Control-zone geography, not distance, determines operational feasibility. Adjacent localities under different authorities can differ entirely in access, visa recognition and permit validity.
- Communications and connectivity disruption is a recurring feature and should be treated as a planning assumption rather than an exceptional event; every movement plan requires an offline fallback and a pre-agreed silence protocol.
- Bureaucratic impediment, travel permits, visa issuance, customs clearance and partner registration, causes more programme delay than kinetic activity does.
- Aerial and indirect-fire risk concentrates around airfields, fuel depots, telecommunications infrastructure and military-adjacent facilities; office and residence siting decisions should be made against that map.
- Cross-border operations from neighbouring states carry their own political exposure and should be assessed as separate operating models, not as extensions of a Sudan country programme.
- Displacement pressure into Chad, Egypt, South Sudan and Ethiopia is generating secondary risk in host communities and along reception corridors.
Analyst assessment
We assess with high confidence that access will remain contested and administratively constrained through 2027, with periods of localised improvement that do not indicate structural change.
We assess with moderate confidence that the most probable serious incident affecting international staff is proximity or infrastructure exposure, being near a struck or contested site, rather than deliberate targeting.
We assess with moderate confidence that organisations relying on a single access channel or single supply route will experience at least one full suspension event during any twelve-month operating period.
