Supply Chain Disruption And How To Stay Safe From Third-Party Risks (A Strait of Hormuz Case Study)

The Strait of Hormuz has always been described as the world’s most critical energy chokepoint. Today, it is not just a shipping concern; it is a direct business continuity and cyber risk event for every organization operating in the GCC.
Here is what is happening, why it matters beyond the oil price, and what your GRC programme needs to do about it right now.
What Is Happening
Since February 28, 2026, tanker traffic through the Strait of Hormuz dropped first by approximately 70%, with over 150 ships anchoring outside the strait to avoid risks, and traffic has since dropped to near zero. This disruption affects approximately 20% of the world’s daily oil supply.
Beginning on March 4, Iranian forces declared the Strait “closed,” threatening and carrying out attacks on ships attempting to transit. The UK Maritime Trade Operations Centre reported over a dozen attacks against ships in and around the Strait, with crew members killed on two vessels.
Iran’s IRGC has stated it will not allow “a litre of oil” through the Strait of Hormuz, warning that any vessel linked to the US, Israel, or their allies will be considered a legitimate target.
This is no longer a regional energy story. It is a supply chain, operational, and cyber risk event, and GCC organizations need to treat it as one.
Why This Is a Business Continuity Crisis, Not Just an Oil Price Story
Most organizations in the GCC are watching oil prices and assuming the impact stops there. It does not.
If Strait of Hormuz disruptions force vessel rerouting, inland port disruption escalates quickly. The initial ocean impact may take 10 to 14 days to appear, but the real pressure typically hits within 2 to 5 weeks as diverted containers arrive in clusters, terminal congestion rises, and drayage demand outpaces truck and chassis availability.
Ports in the GCC region such as Jebel Ali and Khor Fakkan are transshipment hubs that serve as intermediary points in global networks, meaning a prolonged disruption does not just affect inbound goods. It disrupts the movement of everything your business depends on to operate.
Petrochemical inputs, plastics, rubber, electronics, batteries, and pharmaceuticals are all among the inputs and commodities at risk. If your organization relies on any vendor, supplier, or logistics partner that moves goods through the strait, your BCP needs to account for that today.
The Cyber Dimension Nobody Is Talking About Loudly Enough
Here is where it gets specific for GRC and security teams.
Supply chain disruption under crisis conditions creates a predictable pattern of cyber risk:
Rushed procurement bypasses vendor vetting. When regular suppliers go dark, procurement teams move fast. New vendors are onboarded without the usual due diligence. Contracts are signed without cyber incident notification clauses. Third-party risk frameworks that looked solid in February have gaps opening in them right now.
Operational pressure creates shadow IT. When systems are strained and teams are under pressure to keep things moving, employees find workarounds. Unauthorized tools, personal devices, unsanctioned cloud storage. Every workaround is a potential entry point.
Energy and logistics sectors are active targets. The same threat actors disrupting physical shipping lanes are running parallel cyber operations against GCC critical infrastructure. Organizations in energy, logistics, ports, and financial services are not bystanders; they are primary targets.
Insurance and compliance gaps surface. Several Omani ports, including Duqm and Salalah, have already been struck by drones, with at least one fuel storage tank damaged, and Sohar has fallen within an insurer’s war risk area. War risk clauses in cyber insurance policies are being stress-tested in ways most legal and compliance teams have not reviewed since they were written.
Supply Chain Disruption Expands Third-Party Risk
The closure of the Strait of Hormuz is fundamentally a supply chain disruption event, and supply chain disruptions almost always translate into third-party cyber risk.
When logistics routes change, vendors change.
Suppliers that normally provide materials may be delayed or unable to deliver. Procurement teams start sourcing alternatives quickly to keep production and operations running.
This is where risk management processes are often bypassed.
New vendors may be onboarded without proper security reviews. Contract terms may omit cybersecurity requirements. Incident notification clauses may never be discussed.
Every one of those gaps creates a potential exposure point.
For many organizations, third parties already represent the largest external attack surface. Under crisis conditions, exposure expands quickly.
This is why third-party risk management should move from a periodic compliance exercise to a real-time governance function during geopolitical disruptions.
How Complyan Supports Third-Party Risk Governance
Managing vendor risk during a crisis requires structure. Manual spreadsheets and fragmented processes cannot keep up when vendors are changing rapidly.
This is where structured GRC platforms become essential.
Complyan helps organizations maintain visibility and control over their third-party ecosystem even during periods of operational disruption.
Using Complyan, organizations can:
- Maintain a centralized register of all vendors and supply chain partners
• Run structured risk assessments before onboarding new vendors
• Track compliance requirements aligned with frameworks such as ISO 27001 and NIST
• Monitor vendor security posture and contractual obligations
• Maintain audit-ready documentation for regulators and internal governance
Most importantly, Complyan allows risk teams to accelerate vendor assessments without abandoning governance controls.
In crisis conditions, speed is necessary.
Control is still essential.
A structured third-party risk program ensures organizations can adapt their supply chain without expanding their cyber exposure.
What Your GRC Programme Must Address Right Now
- Review your BCP for supply chain failure scenarios
Most business continuity plans are built around isolated outages or natural disasters. They do not account for a multi-week disruption to the primary maritime corridor serving 20% of global oil trade. Pull your BCP and ask: what is our RTO and RPO if our key logistics vendors are non-operational for 30, 60, or 90 days? Do you have alternative suppliers identified and pre-vetted?
- Accelerate third-party risk reviews
Any vendor with physical operations in or near the strait zone needs an immediate risk reassessment. Check your vendor contracts; do they include cyber incident notification obligations? Do they have their own BCP that accounts for this scenario? ISO 27001 Annex A.15 and NIST CSF ID.SC exist precisely for moments like this.
- Check your cyber insurance war exclusion clauses
Now is the time, not after an incident, to review exactly what your cyber insurance policy covers during declared or undeclared conflict. War exclusion clauses are broad, and courts have interpreted them broadly. Work with your legal and compliance team to understand your actual exposure.
- Tighten vendor onboarding controls
If your procurement team is bringing in new vendors at speed under supply pressure, your vendor risk management process needs an emergency lane, not an open door. Create an expedited but non-negotiable onboarding checklist that includes minimum cybersecurity requirements, even under crisis conditions.
- Brief your board on the convergence
The physical crisis and the cyber crisis are not separate events. Your board needs to understand that the same conflict closing the Strait of Hormuz is the same conflict driving a surge in cyberattacks across all six GCC states. The risk picture is one picture. Present it as one.
Conclusion
The Strait of Hormuz disruptions underscore the vulnerability of critical maritime chokepoints to geopolitical tensions and their potential to transmit shocks across supply chains and commodity markets.
For GRC professionals in the GCC, this is not a macroeconomic story to observe from a distance. It is an active stress test of your business continuity framework, your third-party risk programme, your vendor controls, and your cyber insurance coverage.
Organizations that respond effectively will treat this moment as more than a logistics disruption. It is a governance test. Supply chains are shifting, employees are working remotely, and vendors are being onboarded under pressure. Each of these changes introduces cyber risk that must be actively managed.
GRC programmes that remain structured, visible, and responsive will be the difference between organizations that absorb this disruption and those that lose control of their operational risk.
Complyan helps GCC organizations manage compliance and cyber risk with clarity, structure, and confidence, whatever the threat environment. Get in touch to assess your BCP and third-party risk posture today.
