Businesses are under more pressure than ever to demonstrate that they have taken appropriate measures to minimise the risk of a cyber-attack…not only to protect themselves but also to safeguard their supply chain partners.
Regulations such as Def-Stan and the Cyber Resilience Bill, as well as others in the pipeline, are making security maturity a mandatory requirement for conducting business.
A strong SOC and Threat Detection & Response capability are key indicators of readiness. But building them requires the right people, technology, and constantly evolving processes.
The Buyer’s Dilemma: Microsoft Sentinel and the Reality of Ongoing Management
Building any SOC requires significant investment in people, technology, and processes. The costs of hiring skilled analysts, maintaining cutting-edge tools, and ensuring 24/7 monitoring can add up quickly.
Many organisations opt for Microsoft Sentinel due to its apparent ease of setup, cloud-native capabilities, and deep integration with existing Microsoft security tools. However, what often goes unnoticed is the significant skill and effort required to maintain and evolve Sentinel in line with new and evolving threats.
While Sentinel provides an intuitive starting point for security monitoring, ongoing success with the platform demands continuous investment in:
- Maintaining and Optimising Collectors: Ensuring that data sources remain properly configured and optimised for cost and performance.
- Testing and Tuning Analytics Rules: Regularly refining detection logic to minimise false positives and improve detection efficacy.
- Creating and Evolving Workbooks: Designing dashboards and visualisation tools that offer meaningful insights into security trends.
- Integrating Latest Threat Intelligence into Hunting Queries: Keeping Sentinel aligned with the latest threat intelligence feeds for proactive detection.
- Maintaining Watchlists: Ensuring that high-value indicators of compromise (IoCs) and other key security assets remain up to date.
- Developing and Evolving Automation using Playbooks and Logic Apps: Automating responses to alerts using Sentinel’s playbook and logic app functionality to improve response times and reduce manual workload.
This complexity often takes security teams by surprise. Without the right expertise, organisations struggle to keep Sentinel operating at peak effectiveness. This often leads security decision makers to evaluate the options for outsourcing the operation to a Managed Security Services Provider (MSSP) or Managed Detection & Response (MDR) Service provider.
For many security decision-makers, outsourcing to an MSSP / MDR provider appears to be the straightforward choice. However, not all MSSPs and their service approaches are the same. Choosing the wrong provider can lead to issues such as:
- Inefficiencies
- Wasted resources
- Security gaps
However, the right partnership can enhance your organisation’s resilience and compliance posture. Understanding the key differences and knowing what to look for in a provider is crucial to making an informed decision.
Bridging the Gap with a Sentinel Operations Assessment
Before outsourcing or reconfiguring your SOC, it’s worth understanding where your current Sentinel deployment stands. The Sentinel Operations Assessment from e2e-assure offers a detailed review of your existing configuration, analytics, automation, and threat detection capabilities. It provides a prioritised roadmap to uplift your SOC maturity – whether you’re managing Sentinel in-house or working with a provider.
This assessment is ideal for organisations that:
- Are unsure whether their current Sentinel setup is delivering ROI
- Have recently undergone transformation or M&A activity
- Want to benchmark their SOC maturity and identify optimisation opportunities
Your next steps…
Microsoft Sentinel is a powerful, cloud-native SIEM, but unlocking its full potential requires more than just initial deployment. Continuous tuning, proactive threat hunting, automation, and platform optimisation are essential to keep detection sharp and response times low.
If you’re finding it difficult to manage Sentinel in-house, or you’re unsure whether your current setup is delivering maximum value, it might be time to consider bringing in external support. But choosing the right Managed Security Services Provider (MSSP) is a critical decision.
In our next blog, Choosing the Right MSSP for Microsoft Sentinel and Modern SOC Operations, we explore how to evaluate potential partners, what questions to ask, and how to avoid common pitfalls when outsourcing your SOC.
