Managed SIEM FAQs

Choosing to outsource a Security Information and Event Management (SIEM) solution to a third party can be seen as the most balanced option in comparison to building your own solution or buying an off-the-shelf product.

A managed SIEM service allows you to save time and resource by letting a third party proactively look for threats on your behalf. Any security events or outcomes are escalated directly to you, instead of floods of alerts. You’ll also benefit from no dedicated hardware or support contracts to manage and access to a wider variety of threat intelligence.

By using a managed SIEM solution such as Defense.com, you can combine the best of technology and human expertise for 24/7 threat monitoring.

We can ingest logs from any system or vendor that provides security value, including:

  • WAF, load balancers
  • Microsoft 365
  • Firewalls, switches and routers
  • AV/endpoint
  • Windows/Linux servers
  • Custom application logs
  • AWS EC2 Instances
  • AWS CloudWatch
  • Azure Sentinel
  • Azure Virtual Machines
  • Google Cloud Platform

Here are just some examples of the runbooks that will determine what actions are taken for different types of events and alerts.

Microsoft 365/Entra ID:

  • Potentially malicious URL click detected
  • Creation of forwarding/redirect rule
  • Unfamiliar sign-in properties observed
  • Atypical travel

Endpoint protection:

  • AV/malware alert seen
  • Malware clean failed
  • Malware clean successful

Servers/applications:

  • Privilege escalation
  • Vulnerability being exploited
  • Multiple failed logins
  • Malicious PowerShell usage

Network/UEBA:

  • DoS/DDoS behaviour
  • Large transfer of data, especially during out of office hours
  • Sudden deviation from the baseline level of observed traffic
  • Suspicious internal activity

You’ll get up to 1 year of archived logs as standard to meet compliance requirements, which can be extended if required. 90 days of ‘always hot’ log data will be available for immediate searching.

Most larger vendors price their Managed SIEM service by log volumes, EPS or data storage capacity. However, this approach isn’t scalable or cost-effective and leaves you constantly calculating your usage each month.

At Defense.com we believe that good security doesn’t need to be expensive (or complicated!), so we price our service based on the number of log sources you have. This means you can clearly see what’s included, with a consistent and predictable price per month.
