Ten tips for buying managed SIEM

25 February 2020

SIEM isn't a one-size fits all proposition. Organisations have unique IT estates, face unique threats and risks, and have unique requirements from their security solutions. Finding the right SIEM (security information and event management) solution means weighing up your needs and matching them to the vendor and service who can best satisfy them, and at the right price.

To help you choose wisely, we've put together these 10 tips for getting a SIEM service that meets your requirements. Some are factors to bear in mind when choosing, others are questions to ask of potential service providers. Together they'll help you make an informed buying decision.

1) Implementation - consider if you want immediate benefit from a system that detects threats from day one, or if you have more complex operations that require customisation and fine-tuning.

2) Life cycle management - you need the ability to manage the full discovery and rediscovery of critical assets. Ensure your product has proven search and storage efficiency, and that it can quickly and accurately query data, including historical data.

3) Integration - to detect advanced threats, look for products that easily integrate and ingest external intelligence sources, such as threat intelligence, access management systems, database activity monitoring and file integrity monitoring.

4) Integrated security - aside from log management, look for providers with out-of-the-box security capabilities including asset management, behavioural monitoring, vulnerability assessment, file integrity management and intrusion prevention and detection.

5) Deployment options - your infrastructure is likely to span the data centre, public cloud and a virtualised private cloud. You will want a single platform solution that can monitor both cloud and on-premises infrastructure.

6) Compatibility - validate all your logging needs beforehand. Ensure any candidate SIEM product is compatible, and that it can parse and normalise all logs.

7) Reporting - you will want to see in real-time what is happening on your estate via easy-to-interpret visual dashboards and reports. Find tools that allow you to create fast, accurate and personalised reports to ensure regulatory compliance, and streamline audits.

8) Threat intelligence - look for a provider that can deliver continuous, actionable threat intelligence from within the platform, combining assessment, detection and response. Fast, automated feeding in of threat information can help narrow the window of attack.

9) Licensing - licensing models vary. Some - based purely on the number of events, or log volume - can make growth costly, or force you to limit what is monitored. Ensure you have a baseline of what you want to monitor.

10) Growth - as your business is likely to expand, ensure the technology you select can accommodate and scale with you, especially when it comes to secure log storage.


Like we say, SIEM isn't a one-size fits all proposition, but the right vendor will have a flexible offering, and an approach that puts your business needs at the centre of a solution that's as unique as your requirements. Ideal places the customer at the centre of everything it does, will tailor its in-house Managed SIEM service to your needs, and will prove its value through proof-of-concept testing.
