Data Retention and Secure Disposal

Organisations create and store information every day. Customer records, employee files, contracts, financial documents, emails, system logs, project materials, and operational data may be kept across business applications, cloud platforms, shared drives, physical archives, employee devices, and backup systems.

Some of this information must be retained to meet legal, regulatory, contractual, or operational requirements. Other data may no longer serve a valid business purpose. When information is kept indefinitely, it increases storage costs, creates unnecessary complexity, and exposes the organisation to avoidable security, privacy, and compliance risks.

Data Retention and Secure Disposal helps you decide what information should be kept, how long it should be retained, and how it should be securely deleted or destroyed when it is no longer required. At CA, we help organisations establish practical retention arrangements that protect information throughout its lifecycle and support consistent decisions across systems, departments, and locations.

Why This Matters

Keeping information for longer than necessary can appear safer than deleting it. In practice, excessive retention often creates additional risk.
Old records may contain inaccurate, duplicated, or sensitive information. Former employees may still appear in archived systems. Customer data may remain accessible long after the original purpose has ended. Documents may be stored in several locations, making it difficult to know which copy is current or whether all copies have been removed.
At the same time, deleting information too early can create legal, regulatory, contractual, or operational problems. Important evidence may be lost, business records may become unavailable, and the organisation may be unable to respond effectively to an audit, dispute, investigation, or customer request.
Effective Data Retention and Secure Disposal helps you:

🎯

Meet legal and regulatory obligations

Retain business records for the periods required by applicable laws, regulations, contracts, and industry standards.

📊

Reduce unnecessary data exposure

Remove information that no longer has a valid business, legal, or regulatory purpose.

🛡️

Improve information management

Establish clear rules for how long different categories of information should be kept and who is responsible for managing them.

🤝

Support audits and investigations

Ensure that relevant records remain available, complete, and accessible for the required period.

💡

Control storage and operational costs

Reduce the volume of outdated, duplicated, and unnecessary information held across systems and physical locations.

🔒

Dispose of information securely

Ensure that sensitive information cannot be reconstructed, recovered, or accessed after its approved disposal.

Our Approach

We develop retention and disposal arrangements around the information your organisation holds, the reasons it is used, and the systems and processes that support it.
Our objective is not simply to create a retention schedule. We help establish a practical operating model that connects policy requirements with clear ownership, technical controls, employee responsibilities, and evidence of appropriate disposal.

Understand your information environment

We begin by identifying the main categories of information created, received, processed, and stored by the organisation.
This may include personal data, employee records, customer information, financial documents, contracts, correspondence, technical records, system logs, security information, intellectual property, and operational documentation.
We consider where this information is held, including business applications, databases, cloud platforms, collaboration tools, email systems, employee devices, shared folders, physical archives, backup environments, and external service providers.
We also examine how the information supports business activities. Why is it collected? Who uses it? Is it required for legal, regulatory, contractual, or operational purposes? Does the same information exist in several locations or formats?
This provides a clearer view of the organisation’s information landscape and helps identify areas where retention practices may be inconsistent or poorly understood.

Define retention requirements

We help determine how long different categories of information should be retained.
Retention periods may be influenced by legislation, regulatory expectations, contractual commitments, limitation periods, litigation requirements, industry practices, and legitimate operational needs.
Where several requirements apply to the same information, we help identify an appropriate and defensible retention period. We also consider the risks associated with keeping information for too long or deleting it prematurely.
Each retention rule should clearly define:
- The category of information covered
- The purpose for which the information is retained
- The event that starts the retention period
- The required retention period
- The system or location where the information is held
- The responsible business or information owner
- The approved method of disposal
- Any exceptions, review requirements, or legal holds
The result is a practical retention schedule that can be understood and applied by business, technology, compliance, privacy, legal, and records management teams.

Identify gaps and unnecessary retention

We assess whether existing retention practices reflect the approved requirements.
This may involve reviewing system configurations, storage locations, archive processes, backup arrangements, physical records, supplier platforms, and employee working practices.
We look for information that is:
- Retained without a clear purpose
- Stored beyond the approved period
- Duplicated across multiple locations
- Kept in inactive or outdated systems
- Accessible to more people than necessary
- Difficult to locate or delete
- Stored by suppliers without sufficient oversight
- Subject to conflicting retention requirements
- Excluded from existing disposal processes
The findings are prioritised according to the sensitivity of the information, the scale of the issue, applicable obligations, and the potential impact on the organisation and individuals.

Establish secure disposal methods

Deleting a file or disposing of a physical record does not always mean the information has been permanently removed.
Data may remain recoverable from deleted folders, archives, backup systems, storage devices, application databases, or supplier environments. Physical documents and media may also create exposure if they are discarded without appropriate controls.
We help define secure disposal methods based on the sensitivity, format, location, and storage technology involved.
These methods may include:
- Permanent deletion from applications and storage platforms
- Secure wiping of devices and removable media
- Approved destruction of physical documents
- Destruction or sanitisation of retired equipment
- Controlled deletion from cloud services
- Removal of archived and duplicated information
- Deletion or anonymisation of personal data
- Confirmation of disposal by external providers
- Documentation of completed disposal activities
The disposal method should be proportionate to the sensitivity of the information and should prevent unauthorised recovery or reconstruction.

Manage legal holds and approved exceptions

Information that would normally be deleted may need to be preserved because of litigation, an investigation, an audit, a regulatory request, or another formal requirement.
We help establish a clear legal hold and exception process so that relevant information is protected from routine deletion.
The process should define who can authorise a hold, which records are covered, how affected employees and system owners are informed, and how the hold is implemented across relevant locations.
It should also include regular reviews. Information should not remain under a legal hold indefinitely after the underlying requirement has ended.
Once the hold is released, the information should return to the standard retention and disposal process unless another valid requirement applies.

Implement retention controls

A retention schedule creates value only when its requirements are reflected in everyday systems and processes.
We help translate retention rules into practical controls. Depending on the environment, this may include automated deletion, lifecycle management settings, archive rules, employee reminders, approval workflows, access restrictions, or manual review processes.
We also support the integration of retention requirements into:
- System development and procurement
- Data classification
- Privacy and information security reviews
- Employee onboarding and offboarding
- Contract and supplier management
- Records management
- Incident response
- Business process design
- Cloud migration and system decommissioning
Where automated deletion is introduced, we recommend testing the controls before full implementation. This helps confirm that the correct information is removed at the correct time and that legal holds, exceptions, and required records are not affected unintentionally.

Manage supplier and cloud service responsibilities

External providers may store or process information on behalf of the organisation. This does not remove the organisation’s responsibility for ensuring that the information is retained and disposed of appropriately.
We review whether supplier agreements clearly address retention periods, deletion requirements, backup copies, subcontractors, data return, contract termination, and evidence of secure disposal.
We also consider whether the organisation can request deletion during the relationship, how quickly the provider must act, and whether deletion applies to active systems, archives, and backups.
When a service ends, the organisation should know what information will be returned, what will be deleted, how long the process will take, and what evidence will be provided.

Monitor, review, and improve

Retention requirements and information environments change over time. New regulations may be introduced, business processes may develop, systems may be replaced, and new categories of information may be created.
We help establish ownership, review schedules, reporting methods, control testing, and processes for managing exceptions.
Monitoring may include:
- Records that have reached the end of their retention period
- Completed and overdue disposal activities
- Information subject to legal holds
- Systems that do not support required retention controls
- Supplier compliance with deletion requirements
- Policy exceptions and unresolved issues
- Volumes of outdated or duplicated information
- Evidence of completed secure disposal
Regular reviews help ensure that retention rules remain accurate, disposal controls continue to work, and responsibilities are understood across the organisation.

The Business Value

Data Retention and Secure Disposal with CA gives your organisation greater control over how long information is kept and what happens when it is no longer required.
It helps reduce the volume of unnecessary data, limit exposure during cyber incidents, improve compliance, and manage storage resources more effectively. It also provides clearer evidence that information is being retained and disposed of according to defined and defensible rules.
A structured programme makes it easier to respond to audits, investigations, legal disputes, regulatory enquiries, data subject requests, and customer assessments. Teams can locate required records more efficiently and explain why particular information has been retained or deleted.
Secure disposal also reduces the risk associated with old systems, unused devices, physical records, duplicate files, and information held by former suppliers. Instead of allowing outdated data to accumulate, the organisation can remove it through a controlled and documented process.
Most importantly, effective retention and disposal strengthens trust. Customers, employees, partners, and regulators can have greater confidence that the organisation keeps information only for as long as it is genuinely needed and protects it throughout its full lifecycle.

Next Step

Information should be retained for a clear reason, not simply because it may be useful one day.
