Cloud-Based vs On-Premise Evidence Management Systems
Evidence management is a critical function for organisations that handle sensitive data, including law enforcement, legal firms, and corporate security departments. Choosing the right evidence management system (EMS) is a significant decision that impacts security, accessibility, cost, and compliance. This article provides a detailed comparison of cloud-based and on-premise evidence management systems to help you make an informed choice.
Cost Analysis: Cloud vs On-Premise
One of the primary considerations when selecting an EMS is the overall cost. The cost structures for cloud-based and on-premise systems differ significantly.
Cloud-Based Costs
Cloud-based EMS solutions typically operate on a subscription model. This means you pay a recurring fee, usually monthly or annually, for access to the software and its associated services. Key cost components include:
Subscription Fees: These fees vary depending on the number of users, storage capacity, and features required.
Storage Costs: Cloud storage is generally priced per gigabyte or terabyte. As your evidence library grows, your storage costs will increase.
Bandwidth Costs: Uploading and downloading evidence can incur bandwidth charges, especially for large video files.
Implementation Costs: While often lower than on-premise, there may still be costs associated with data migration and system configuration.
Support Costs: Most cloud providers include basic support in their subscription fees, but premium support may come at an additional cost.
The main advantage of cloud-based systems is the lower upfront investment. You avoid the large capital expenditure associated with purchasing and maintaining hardware.
On-Premise Costs
On-premise EMS solutions involve a significant upfront investment in hardware and software. Key cost components include:
Software Licences: These are typically perpetual licences, granting you the right to use the software indefinitely.
Hardware Costs: This includes servers, storage devices, networking equipment, and backup systems.
Implementation Costs: Installing and configuring the software and hardware can be complex and require specialised expertise.
IT Staff Costs: You'll need dedicated IT staff to manage and maintain the system.
Maintenance and Support Costs: Ongoing maintenance, software updates, and technical support can add to the total cost of ownership.
Facilities Costs: On-premise systems require physical space, power, and cooling, which can contribute to overhead costs.
While the initial investment is higher, on-premise systems can be more cost-effective in the long run for organisations with large evidence libraries and dedicated IT resources. However, it's crucial to factor in all associated costs, including hardware upgrades and potential downtime.
Security Considerations
Security is paramount when dealing with sensitive evidence. Both cloud-based and on-premise systems have their own security strengths and weaknesses.
Cloud-Based Security
Cloud providers invest heavily in security infrastructure and employ robust security measures, including:
Physical Security: Data centres are typically located in secure facilities with multiple layers of physical security.
Network Security: Firewalls, intrusion detection systems, and other network security tools protect against unauthorised access.
Data Encryption: Data is encrypted both in transit and at rest to protect it from interception and theft.
Access Controls: Role-based access controls ensure that only authorised users can access sensitive data.
Compliance Certifications: Many cloud providers hold industry-standard security certifications, such as ISO 27001 and SOC 2.
However, cloud-based systems also introduce potential security risks, including:
Data Breaches: While rare, data breaches can occur in the cloud, potentially exposing sensitive evidence.
Vendor Lock-in: Migrating data from one cloud provider to another can be difficult and costly.
Compliance Challenges: Ensuring compliance with regulations like GDPR and HIPAA can be more complex in the cloud.
When choosing a cloud-based EMS, it's essential to select a provider with a strong security track record and comprehensive security policies. Consider what Evidence offers in terms of security and compliance.
On-Premise Security
On-premise systems offer greater control over security, as you are responsible for implementing and maintaining all security measures. Key security advantages include:
Physical Control: You have complete control over the physical security of the hardware and data.
Data Residency: Data remains within your organisation's network, which can be important for compliance reasons.
Customisation: You can customise security policies and controls to meet your specific needs.
However, on-premise security also presents challenges:
High Costs: Implementing and maintaining robust security measures can be expensive.
Expertise Required: You need skilled IT staff to manage and monitor security.
Vulnerability to Attacks: On-premise systems can be vulnerable to cyberattacks if not properly secured.
Disaster Recovery: Implementing a robust disaster recovery plan is crucial to protect against data loss.
Scalability and Flexibility
Scalability and flexibility are important considerations, especially for organisations with growing evidence libraries.
Cloud-Based Scalability
Cloud-based systems offer excellent scalability and flexibility. You can easily scale up or down your storage capacity and computing resources as needed, without having to invest in additional hardware. This is particularly beneficial for organisations with fluctuating evidence volumes. Cloud solutions also allow for quick deployment and integration with other systems.
On-Premise Scalability
On-premise systems can be scaled, but it requires significant planning and investment. Adding more storage capacity or computing power involves purchasing and installing additional hardware. This can be time-consuming and disruptive. On-premise systems may also be less flexible in terms of adapting to changing business needs.

Maintenance and Support
Maintenance and support are crucial for ensuring the smooth operation of your EMS.
Cloud-Based Maintenance
With cloud-based systems, the provider is responsible for maintaining the infrastructure and software. This includes applying security patches, performing software updates, and monitoring system performance. This reduces the burden on your IT staff and frees them up to focus on other tasks. Support is typically provided by the cloud provider through various channels, such as phone, email, and online chat.
On-Premise Maintenance
With on-premise systems, you are responsible for all maintenance and support. This includes hardware maintenance, software updates, security patching, and troubleshooting. This requires dedicated IT staff with the necessary expertise. Maintenance can be time-consuming and costly, but it gives you greater control over the system.
Accessibility and Collaboration
Accessibility and collaboration are important for ensuring that authorised users can access and share evidence easily.
Cloud-Based Accessibility
Cloud-based systems offer excellent accessibility. Users can access evidence from anywhere with an internet connection, using a variety of devices. This facilitates collaboration among different teams and departments. Cloud-based systems also typically offer robust search and indexing capabilities, making it easy to find specific evidence items.
On-Premise Accessibility
On-premise systems can be accessed remotely, but it requires setting up and maintaining a secure remote access solution. This can be complex and costly. Accessibility may also be limited by network bandwidth and security restrictions. Collaboration may be more difficult with on-premise systems, as users may need to be physically present in the same location to access evidence.
Compliance Requirements
Compliance with relevant regulations is essential for evidence management. Different industries and jurisdictions have different compliance requirements.
Cloud-Based Compliance
Cloud providers often offer compliance certifications, such as ISO 27001, SOC 2, and HIPAA. These certifications demonstrate that the provider has implemented appropriate security controls to protect sensitive data. However, it's your responsibility to ensure that the cloud-based EMS meets your specific compliance requirements. This may involve conducting due diligence on the provider and implementing additional security measures. Consider reviewing the frequently asked questions about compliance.
On-Premise Compliance
With on-premise systems, you are responsible for ensuring compliance with all relevant regulations. This requires implementing appropriate security controls, documenting policies and procedures, and conducting regular audits. Compliance can be complex and costly, but it gives you greater control over the process.
In conclusion, both cloud-based and on-premise evidence management systems have their own advantages and disadvantages. The best choice for your organisation depends on your specific needs, budget, and technical capabilities. Carefully consider the factors discussed in this article to make an informed decision that meets your requirements.
