Third-Party Risks in Hybrid Cloud Backup

Hybrid cloud backup combines on-premises storage with cloud-based solutions, offering flexibility and scalability for UK businesses. However, partnering with third-party providers introduces risks that can impact security, compliance, and reliability. Here's what you need to know:

• Security Risks: Third-party providers can be targets for cyberattacks. Issues like misconfigured settings, outdated encryption, or unclear accountability under shared responsibility models can expose sensitive data.
• Compliance Challenges: UK organisations must meet GDPR and other regulations, even when outsourcing. Data residency, cross-border transfers, and sector-specific rules often complicate compliance.
• Vendor Lock-In: Proprietary systems can make switching providers expensive and complex, reducing flexibility.
• Access Mismanagement: Poor access controls can lead to insider threats or unauthorised data access.
• Service Reliability: Outages or provider instability can disrupt operations and recovery efforts.

How to Manage These Risks:

1. Evaluate Providers: Check certifications (e.g., ISO 27001), financial stability, and incident response plans.
2. Strengthen Contracts: Include clear terms for liability, audits, and data portability.
3. Implement Security Measures: Use client-side encryption, access controls, and regular penetration testing.
4. Monitor Providers: Continuously track performance, compliance, and security practices.
5. Plan for Redundancy: Use multiple providers and test recovery processes regularly.

UK businesses must balance cost efficiency with compliance and security. Addressing third-party risks requires thorough preparation, continuous oversight, and robust contingency planning.

Main Third-Party Risks in Hybrid Cloud Backup

When it comes to hybrid cloud backup, UK organisations must tackle a range of risks associated with third-party providers. Properly addressing these risks is essential to safeguarding data and ensuring compliance with legal and regulatory requirements.

Data Breaches and Security Vulnerabilities

Third-party providers often hold massive amounts of data for multiple clients, making them prime targets for cyberattacks. The shared responsibility model - a common framework in cloud services - can sometimes blur the lines of accountability. This lack of clarity can leave security gaps that attackers may exploit.

Misconfigured backup settings or infrastructure can also expose sensitive data, a particularly serious concern for UK organisations handling personal information. Under GDPR, any data breach can lead to hefty fines and damage to reputation.

Encryption practices are another critical factor. If a provider uses outdated encryption methods or poorly manages encryption keys, data can be at risk both during transmission and while stored. These weaknesses leave organisations vulnerable to unauthorised access or interception.

Adding to these security concerns, the regulatory environment further complicates matters.

Compliance and Regulatory Challenges

Navigating the UK's complex regulatory requirements becomes even trickier when outsourcing to third-party providers. GDPR mandates that organisations retain control over how personal data is processed, even when external vendors are involved. This means ensuring that providers implement robust technical and organisational safeguards.

Beyond GDPR, sector-specific regulations add extra layers of responsibility. For instance, financial institutions must meet FCA standards, while healthcare organisations are bound by NHS Digital requirements. Additionally, multi-jurisdictional data regulations can make compliance even more challenging, particularly when providers operate across borders.

Data transfer restrictions are another hurdle. If backup data is stored or processed outside the UK, organisations must ensure that the provider meets adequate protection standards. This task is complicated by evolving international agreements and differing privacy laws, which can create uncertainty and risk.

But regulatory issues are only one piece of the puzzle. Organisations also face challenges tied to their reliance on specific vendors.

Vendor Lock-In

Many providers use proprietary backup formats or custom APIs, which can trap organisations in costly, rigid solutions. Once locked into a provider's ecosystem, switching to a different service can become prohibitively expensive. Migration costs, especially for large enterprises, can be immense, leaving organisations with limited options.

Technical dependencies deepen this challenge. When backup systems are tightly integrated with a provider's tools and infrastructure, adapting to new business needs or integrating with other systems becomes both time-consuming and expensive. This lack of flexibility can weaken the overall resilience of hybrid cloud backup strategies.

Third-party relationships also introduce internal security risks.

Insider Threats and Access Mismanagement

Third-party providers often grant their employees privileged access to backup systems and data, which can create insider threats. Without thorough background checks, strict access controls, or robust monitoring, there’s a risk of data theft, unauthorised changes, or accidental data loss.

Managing access becomes even more complex in hybrid environments where different parties require varying levels of access. Poorly managed access controls can allow ex-employees or contractors to retain access they no longer need. Insufficient audit trails make it difficult to track and address these issues.

The situation becomes even murkier when providers rely on subcontractors or operate across multiple locations. UK organisations may struggle to determine who has access to their data and whether adequate measures are in place to secure it. This lack of visibility directly impacts the reliability of hybrid cloud backup systems.

Finally, operational reliability is another critical area of concern.

Availability and Service Reliability

Service outages can disrupt access to vital backup data, especially during disaster recovery scenarios. If a provider experiences downtime, it can extend business interruptions and drive up recovery costs.

Network connectivity issues between on-premises systems and cloud providers can also hinder backup operations. Slow or unreliable connections may cause backups to exceed acceptable timeframes, leaving critical data unprotected.

Service level agreements (SLAs) often fail to fully safeguard business-critical operations. Even with high uptime guarantees, small periods of downtime can add up over time, potentially resulting in unacceptable gaps in data availability.

Another risk is provider financial instability. If a backup provider faces financial troubles or goes out of business, organisations may lose access to their data or be forced into urgent migrations under less-than-ideal circumstances. This directly impacts the resilience of hybrid cloud backup systems, making provider reliability a key consideration.

Solutions and Best Practices for Reducing Third-Party Risks

Managing third-party risks in hybrid cloud backup environments calls for a practical and proactive approach. The key lies in thoroughly assessing providers, crafting strong contracts, implementing robust security measures, and maintaining continuous oversight.

Conduct Thorough Provider Assessments

Start with an in-depth evaluation of potential providers. Look into their security certifications, such as ISO 27001, SOC 2 Type II, or Cyber Essentials Plus, as these indicate a commitment to security standards. Check their financial stability by reviewing credit ratings and market position, and gather insights from references or existing customers in similar industries.

Pay close attention to their incident response plans. Ask for specifics on how they handle security breaches or outages, including notification timelines, escalation procedures, and recovery protocols. Providers that can't offer clear details on these processes may not be adequately prepared for emergencies.

Examine their technical architecture as well. This includes understanding where your data is stored, their network infrastructure, and their backup and recovery processes. Ensure their setup aligns with UK data protection regulations, and request documentation on their infrastructure's redundancy and disaster recovery capabilities.

Strengthen Contractual Safeguards

Contracts play a pivotal role in reducing third-party risks. Specify clear terms for notification, liability, audits, and data portability. Data residency clauses should ensure that UK data remains within approved jurisdictions.

Liability clauses should be robust enough to cover the potential costs of data breaches, outages, or compliance failures. Some providers may try to limit liability to the monthly service fee, which often falls short of actual costs in a major incident.

Include right-to-audit clauses to maintain oversight. These should allow for both scheduled and unscheduled audits, as well as the option to involve third-party security firms for independent reviews. Data portability requirements should also be clearly defined, detailing formats and timelines for extracting data if you decide to switch providers.

When negotiating service level agreements (SLAs), avoid generic promises. Tailor SLAs to your business needs, specifying recovery time objectives (RTOs) and recovery point objectives (RPOs) for different types of data.

Implement Multi-Layered Security Controls

To minimise risks, maintain control over encryption keys with client-side encryption, enforce role-based access controls, and adopt zero-trust principles. Network segmentation and enhanced monitoring add an extra layer of protection. Regularly review access privileges, especially as staff roles evolve, to ensure only authorised personnel have access to sensitive data.

Don't overlook the importance of penetration testing. While internal systems often receive the most attention, third-party connections can introduce vulnerabilities. Conduct thorough tests of your entire hybrid backup setup annually or bi-annually to identify and address weak points before they are exploited.

Monitor Providers Continuously

Ongoing monitoring is essential to maintain trust and security. Use automated tools to track provider performance, security posture, and compliance status in real time. Security information and event management (SIEM) systems can consolidate logs from both internal systems and third-party services, offering a comprehensive view of potential threats.

Keep an eye on compliance by setting up alerts for certification expirations, security incidents, or changes in a provider's security practices. Performance monitoring should go beyond uptime metrics - track backup speeds, data transfer rates, and recovery test outcomes. Any drop in performance could signal deeper infrastructure issues.

Consider third-party risk management platforms to centralise monitoring efforts. These tools aggregate data from news feeds, security bulletins, and compliance databases, providing early warnings about potential issues. Alongside monitoring, ensure your strategy includes redundancy measures for added protection.

Plan for Redundancy and Disaster Recovery

Using multiple providers can safeguard against complete system failures and strengthen your negotiating position. For example, you might rely on different providers for different data types or adopt a primary-secondary provider model.

Geographic redundancy is critical for UK organisations. Ensure backup copies are stored in multiple UK regions or other approved locations to protect against localised disasters while complying with data residency rules.

Regular recovery tests are vital. Simulate failures with your primary provider to validate that your secondary recovery processes work as intended. Document these procedures and train staff to handle alternative workflows. Many organisations only discover weaknesses in their disaster recovery plans during actual emergencies.

Backup verification should go beyond basic restore tests. Use automated tools to check backup integrity and ensure data consistency. A corrupted backup can create a false sense of security until it's too late. Routine verification ensures your backups are reliable when you need them most.

Finally, don't neglect exit planning. Keep detailed records of data locations, formats, and dependencies. Establish relationships with alternative providers in advance and periodically review migration procedures. Planning your exit strategy early ensures you're prepared for any eventuality, even if your current provider relationship is running smoothly.

Compliance and Legal Requirements for UK Organisations

Navigating compliance is a crucial aspect for UK organisations, especially when managing third-party risks in hybrid cloud backup solutions. The regulatory landscape has become increasingly complex, requiring organisations to stay on top of evolving legislation that affects their relationships with third-party providers.

Understanding UK Data Protection Regulations

When working with third-party providers, UK organisations must adhere to the UK GDPR and the Data Protection Act 2018, as these laws designate your organisation as the accountable data controller [1][3][5]. Adding to the challenge, the Data (Use and Access) Act 2025, which takes effect on 19 June 2025, introduces further complications for managing provider relationships. The Information Commissioner’s Office (ICO) is currently reviewing how this new legislation impacts cloud computing, signalling that updated requirements may soon follow [2][3].

Storing files in the cloud cuts hardware costs and keeps teams productive, but the moment personal data lands on a Dropbox, OneDrive or AWS bucket, the UK GDPR applies. If your provider's security falls short, its servers sit outside the UK, or its terms limit liability, the ICO will look to **you** as data-controller. – Harper James [3]

A key step is determining whether your provider acts as a data processor or a data controller, as this distinction defines their responsibilities under UK GDPR [3]. Typically, backup providers function as data processors, leaving your organisation fully liable for compliance breaches.

The NCSC's Cloud Security Principles offer practical advice for ensuring compliance. Two principles, in particular, stand out: Principle 2 (Asset protection and resilience) and Principle 14 (Secure use of the service). These principles guide organisations in choosing providers that meet their security and compliance needs [1][4]. This highlights the importance of understanding where data is stored, which brings us to the critical issues of data residency and sovereignty.

Data Residency and Sovereignty Concerns

Where your data is stored determines which legal frameworks apply and directly impacts your compliance obligations. Under UK regulations, personal data must either remain within the UK or be stored in a country with adequate data protection standards. If these conditions aren’t met, strict adherence to international data transfer rules is required [3].

Many organisations only discover after the fact that their backup provider stores data across multiple jurisdictions without proper documentation. This can lead to compliance gaps and potential penalties. To avoid this, ask your provider for detailed documentation outlining exactly where your data will be stored, processed, and backed up. Contracts should clearly specify approved storage locations and mandate written consent for any data relocation.

Audit and Reporting Best Practices

Strong audit and reporting practices are essential for meeting stringent data protection requirements. Regular compliance audits are not optional; the ICO expects organisations to demonstrate ongoing compliance through evidence of due diligence and corrective measures [3][5]. Establish continuous verification processes to ensure your provider adheres to promised security measures and contractual obligations [3].

Comprehensive documentation is critical. This should include records of provider assessments, contract terms, security configurations, and incident response plans. Additionally, verify how providers handle access requests, data retention, and deletion to ensure alignment with UK GDPR [3]. The ICO’s enforcement approach places a high priority on your ability to show that reasonable steps were taken to maintain compliance. Regularly testing these processes can help uncover and resolve any weaknesses.

Be ready to respond swiftly to internal or third-party data breaches [3]. Your audit framework should include procedures for breach notifications, impact assessments, and remediation tracking to meet regulatory expectations.

Finally, keep detailed records of your encryption strategies. Whether you encrypt data before uploading it or rely on provider-managed encryption, document the encryption methods, key management processes, and access controls in place [2]. These records are invaluable during regulatory inspections or in the event of a security breach.
