A security weakness in one office can put systems and data across an entire business at risk. Strong information security gives teams a consistent way to protect assets, manage access and respond when something goes wrong.
For businesses operating in several countries, that means combining clear policies with controls that work across different teams, suppliers and legal requirements. The starting point is understanding what you need to protect and where it sits.
Key takeaways
- Map sensitive data, systems, users and suppliers across every location.
- Apply access controls, multi-factor authentication (MFA), patching and tested backups consistently.
- Give staff a clear route to report suspicious activity, then practise incident response.
- Record every personal data breach and assess whether it meets the ICO’s reporting threshold.
- Check which UK rules apply to your sector, and verify local requirements in other countries.
What information security means across borders
Information security is the protection of data and systems against unauthorised access, loss, alteration or disruption. It covers technology, people and processes, so a firewall alone cannot protect a business.
A multinational organisation might store customer records in a UK cloud environment, use a regional payroll provider and rely on staff in several time zones. Each arrangement creates different access paths and risks. A single policy can set the standard, but teams need to apply it in ways that fit their local operations and legal duties.
Map the information that matters
Start by listing the information your organisation holds, where it is stored and who can access it. Include personal data, financial records, intellectual property, operational systems and credentials. Record whether each item sits on company devices, cloud platforms, supplier systems or paper files.
The National Cyber Security Centre (NCSC) recommends identifying sensitive data and its location, then protecting it according to risk. That inventory helps teams decide where to focus investment instead of applying the same level of control to every asset.
Set ownership and accountability
Name the people responsible for key systems and data. IT teams may manage technical controls, while business owners decide who needs access and how long they need it. Legal, privacy and security staff should know when to advise on a breach or a change in data use.
A written policy only helps when staff know who owns each decision. This matters especially where local offices rely on regional providers or where a central security team cannot respond immediately.
Build a security baseline that teams can follow
Businesses need a consistent minimum standard across offices, even when local systems differ. Document the controls that every location must meet, then track exceptions with an owner, reason and review date.
Control access and patch promptly
Give users access only to the systems and data required for their roles. Review permissions when someone joins, changes jobs or leaves, and remove accounts that are no longer needed. Use MFA for internet-facing services and privileged accounts, where possible.
Patch operating systems, applications and network devices according to risk. Internet-facing systems and known vulnerabilities often need faster attention than low-impact tools. A documented process should show who assesses a patch, who approves it and how the team handles systems that cannot be updated promptly.
Protect backups and test recovery
Keep multiple backup copies in different locations. The NCSC recommends including offline backups that are separated from the network, which can help if attackers compromise connected systems.
Backups need regular tests. Check whether teams can restore essential services, how long recovery takes and whether the recovered data is usable. A backup that has never been restored is an assumption, not a proven recovery method.
Staff awareness, security testing and an incident response plan belong in the same baseline. Practical training should show people how to report suspicious messages and unexpected access requests. For a broader view of weaknesses, an IT Security Audit can help assess controls and identify areas that need attention. Businesses can also Protect Your Business with security services matched to their systems and risks.
Coordinate security across countries and suppliers
A central security team can set standards, but it needs local contacts who understand site operations and can act during an incident. Define escalation routes for every office, including who can isolate a device, contact a supplier or approve a service interruption.
A global IT support arrangement should make security responsibilities clear, not create another layer of uncertainty. When evaluating multinational IT support, check how providers handle account access, incident escalation, software updates and evidence of completed work.
Make service coverage measurable
Support contracts should state which systems and locations they cover, how users report security concerns and how urgent cases reach the right team. Confirm whether support is available outside UK business hours, and who is responsible when an issue crosses a supplier boundary.
The terms global IT services and international IT services can cover a wide range of arrangements. Assess actual service levels rather than relying on labels. Ask how the provider coordinates multi-country IT support, shares incident information and protects administrative accounts.
For IT support for multinational companies, a shared service desk can help users follow a common process. However, local escalation contacts remain important when internet access, power or local suppliers are affected. Providers offering IT support for international businesses should also explain how they handle data access and operational handovers across regions.
Keep supplier access under control
List providers that can access company data or systems, including cloud platforms, managed service providers and local IT contractors. Give each supplier only the permissions it needs, monitor privileged access and remove accounts when the contract ends.
Remote IT support can be useful for dispersed teams, but remote access tools need strong authentication and clear logging. Agree how providers will notify you about suspected incidents, preserve relevant records and support investigations. Review those arrangements when a supplier changes its service or adds a new subcontractor.
Prepare to respond to a security incident
A response plan should state how staff report an incident, who leads the investigation and who can make decisions about systems, customers and regulators. Include contacts for key suppliers and make sure the plan works outside normal working hours.
Practise decisions before an incident
Run exercises based on credible events, such as a compromised administrator account or ransomware affecting a shared file system. Decide who can disconnect a device, pause a service or activate recovery procedures. Record gaps and assign actions after each exercise.
In a multinational business, agree how teams share updates across time zones. One incident log and a named decision-maker can prevent conflicting instructions. Keep a record of decisions, timestamps, affected systems and evidence collected.
Assess personal data breaches carefully
The Information Commissioner’s Office (ICO) says organisations must record all personal data breaches, including those they do not report. A breach must be reported to the ICO without undue delay and, where feasible, within 72 hours of awareness if it is likely to risk people’s rights and freedoms.
If a breach is likely to result in a high risk to individuals, the organisation must also notify affected people without undue delay. The assessment should focus on the likely risk to people, not merely on whether the incident has been labelled a cyber attack.
If an investigation is incomplete at 72 hours, the ICO allows information to be supplied in phases. A late report should include an explanation. Keep evidence of the assessment and its reasoning, including when the team became aware of the breach.
Check which rules apply to your organisation
UK businesses may have duties under several laws, depending on their activities and the data they process. The UK GDPR and the Privacy and Electronic Communications Regulations (PECR) address particular data protection and communications obligations. Sector rules or contractual requirements may add further controls.
Understand the scope of the NIS Regulations
The Network and Information Systems Regulations 2018 cover specified essential services and certain digital service providers. The relevant UK sectors include energy, transport, health, drinking water and digital infrastructure. Certain online marketplaces, search engines and cloud computing services are also in scope.
These regulations do not apply to every business. Check whether your organisation or service falls within the defined scope, rather than assuming that operating internationally automatically makes the rules applicable.
Separate current duties from proposed changes
NIS2 is an EU directive, not a UK Act or regulation. A business with EU operations should assess whether EU rules apply to its activities, alongside UK requirements, and seek advice on its particular position.
Parliament’s record, updated 17 Aug 2026, listed the Cyber Security and Resilience Bill as a bill, not an Act. A parliamentary notice said Lords committee-stage consideration was scheduled to begin on 1 Sep 2026. Those records predate October, so check the latest legislation before treating proposed measures as current duties.

Frequently asked questions
Is information security the same as cybersecurity?
Cybersecurity focuses on protecting digital systems and networks. Information security is broader, covering digital and physical information, along with the people and processes that protect it.
Does every personal data breach need to be reported to the ICO?
No. Record every personal data breach, then assess whether it is likely to risk people’s rights and freedoms. That risk determines whether ICO notification is required.
What should a multinational security policy include?
Set minimum controls for access, MFA, patching, backups, incident reporting and supplier access. Assign owners, document exceptions and check local legal requirements before applying the policy across jurisdictions.
How can a business check its security controls?
Review policies, access, systems, supplier arrangements and recovery plans. An IT security review can help identify gaps, while Managed SIEM Services can support ongoing security monitoring.
Make information security part of daily operations
Effective protection comes from knowing what matters, limiting access and practising how the business will respond. For multinational organisations, those controls need clear owners and reliable coordination across locations.
A security programme should fit the risks and operations of the business. Explore Get IT Support for support across locations, or Book a Security Review to identify practical next steps.
