Shifting from a legacy SIEM to a cloud-native solution

Discover the scalability, flexibility, and cost benefits of cloud services

LEARN MORE
Shifting from a legacy SIEM to a cloud-native solution is an increasingly common consideration for many SMBs due to the scalability, flexibility, and cost benefits of cloud services.

If you're contemplating this transition, here are some key considerations:

1. Cost structure
  • Predictable costs: Cloud-native solutions often come with a subscription-based model. Understand the pricing to ensure there are no unexpected costs.
  • Hidden charges: Be aware of potential costs for data ingestion, storage, or egress. These can add up quickly in cloud environments.
2. Data security & privacy
  • Data residency: If your business operates in a region with data residency requirements, ensure the cloud provider can store data within specific geographical boundaries.
  • Encryption: Ensure that data is encrypted both in transit and at rest. Check if you can manage your own encryption keys.
3. Integration with legacy systems
  • Even if you're moving to a cloud-native SIEM, you might still have on-premises systems that need monitoring. Ensure the solution can integrate seamlessly with these systems.
4. Scalability & performance
  • One of the key advantages of cloud-native solutions is scalability. Ensure that the SIEM can scale as your data grows, and you can adjust resources based on your needs.
  • Check if the solution provides real-time or near-real-time analysis even as data scales.
5. Compliance
  • If your industry has regulatory requirements, the cloud-native SIEM should provide the necessary reporting and auditing tools.
  • Some cloud providers offer compliance certifications for their services. This can help in demonstrating compliance for your organisation.
6. Vendor lock-in
  • Understand if you're getting tied to a particular cloud provider's ecosystem and what the implications might be for future changes or migrations.

 

 

7. Operational complexity
  • While cloud-native solutions can offer various benefits, they can also introduce new operational complexities. Ensure your team is prepared or can get the necessary training.
  • Consider solutions that offer straightforward dashboards, automation, and easy-to-use interfaces.
8. Reliability & uptime
  • Research the cloud provider's track record for uptime. Downtime can impact your ability to monitor and respond to security incidents.
  • Understand the provider's Service Level Agreement (SLA) and their commitments regarding availability.
9. Support & community
  • As with any solution, ensure the vendor provides robust support. For SMBs, having accessible and helpful support can be crucial.
  • A strong community around a product can be beneficial for troubleshooting, sharing best practices, and addressing common challenges.
10. Migration & transition
  • Plan for the migration process. There might be complexities in moving from a legacy system, especially in terms of data continuity and maintaining historical records.
  • Consider running both systems in parallel for a short period to ensure the new system captures and analyses data correctly.
11. Flexibility & customisation
  • Check if the cloud-native SIEM offers the flexibility to customise dashboards, alerts, and reports to your specific needs.
  • Some solutions may come with pre-built integrations or playbooks that can accelerate deployment and value realisation.
12. Incident response capabilities
  • Evaluate how the cloud-native SIEM supports your incident response process. This includes integration with other tools, providing context during investigations, and facilitating rapid response.

While cloud-native SIEMs offer many benefits, it's essential to carefully evaluate the potential challenges and ensure that the chosen solution aligns with your SMB's operational, security, and budgetary needs.
