Why choose a Bulletproof managed SIEM?

A key component of our managed SIEM service is an in-house 24/7 Service Operations Centre (SOC). Our SOC analysts work as an extension of your team, proactively looking for malicious activity in your network and taking full ownership of your SIEM service.

Unlike most other managed SIEM providers, we include clear step-by-step remediation advice for each and every security event – meaning you can fix issues fast and get back to other tasks. The Bulletproof managed SIEM service is delivered through our fast, intuitive SaaS platform.

Managed SIEM FAQs

Security Information and Event Management, or SIEM, has quickly become a core component of a business’ information and cyber security defence. A SIEM protects environments by aggregating log data from multiple sources, and correlating it to detect suspicious activity. If an issue is spotted, such as scanning activity from a region not associated with the business, it can be raised as a security alert and appropriate action taken.

You can think of SIEM as a programmed set of rules, where system and user behaviour is mapped against what is considered as normal baseline behaviour within your business. For example, a communication with devices in multiple geographic regions is normal behaviour for a multinational retailer, but not for local Government.

An effective SIEM must be programmed to recognise these different behaviours and raise alerts accordingly. This requires investment in dedicated, knowledgeable staff to manage and maintain the SIEM, and manage the correlations, runbooks and alerts.

Managed SIEM provides a comprehensive and centralised view of security threats across your organisation, empowering your business to make informed decisions about risk management and mitigation. Ultimately, a managed SIEM helps improve your overall security posture, stopping data breaches. A managed SIEM service is also mandated or strongly recommended by a variety of compliance standards, including PCI DSS, ISO 27001, SOC2, GDPR and more.

There are three approaches to incorporating a SIEM into a business: build, buy or outsource. Which option is right for you depends on the size and nature of your business, as well as your security objectives. There are benefits and drawbacks to each option and it’s important to remember that, even within each, no two SIEMs are the same.

Whereas building your own and buying-in need significant capital investments and on-going commitments to resources, outsourcing your SIEM requirements is often seen as the most effective, and cost-efficient, option. Having a third-party manage your monitoring responsibilities is a robust and affordable approach to security. Benefits include:

  • Affordable retainer-based service with no large upfront fees
  • Access to experienced security analysts 24/7
  • Deployment and reconfigurations supported by a trusted third party
  • No hardware appliances or support contracts to manage
  • Access to a wider variety of threat intelligence
  • Proactive threat hunting to uncover hidden threats
  • Immediate access to updates as and when they’re produced – often at no extra cost
  • Native integration with cloud and other modern infrastructures
