Microsoft Security

Microsoft Sentinel Services

Strengthen cyber resilience with intelligent security operations

Cyber threats continue to evolve, while security teams face increasing pressure to manage growing volumes of data, alerts and compliance requirements. Many organisations struggle with fragmented tooling, limited visibility and the challenge of responding quickly to potential threats.
 
Microsoft Sentinel helps address these challenges by bringing security data, analytics and automation together in a cloud-native security operations platform. It provides the visibility needed to identify threats, investigate incidents and improve security operations across your organisation.
 
At Trustmarque Ultima, we help organisations design, deploy and optimise Microsoft Sentinel to deliver practical security outcomes. From strategic planning and implementation through to ongoing support and optimisation, we help you build a security operations capability that is aligned to your business objectives.

Our Microsoft Sentinel Services

Microsoft Sentinel strategy and advisory

Successful security operations begin with a clear understanding of your risks, priorities and operational requirements.

Our specialists work with you to:

  • Assess your current security operations maturity
  • Identify opportunities to improve visibility and threat detection
  • Develop a Microsoft Sentinel adoption or migration strategy
  • Align security operations with compliance and governance requirements
  • Create a practical roadmap for continuous improvement

Microsoft Sentinel implementation

Every organisation's security environment is different. We design and deploy Microsoft Sentinel to support your unique operational and security requirements.

Our implementation services include:

  • Architecture design and configuration
  • Data connector deployment
  • Log source onboarding
  • Detection rule development
  • Dashboard and workbook creation
  • Security use case development
  • Integration with Microsoft security technologies

Detection engineering and optimisation

Effective security monitoring requires more than simply collecting data.

We help organisations create detection strategies that focus on meaningful risks, reduce unnecessary alerts and improve analyst efficiency. By refining detection rules, use cases and operational processes, security teams can focus on responding to genuine threats rather than managing alert fatigue.

Managed Microsoft Sentinel services

Many organisations need additional support to maintain and optimise their security operations capability.

Our managed services help organisations maximise the value of their Microsoft Sentinel investment through ongoing monitoring, administration and optimisation. Services can include:

  • Platform management
  • Threat monitoring support
  • Detection tuning
  • Operational reporting
  • Continuous improvement reviews

Microsoft Sentinel and SecureXpert

Strong security operations depend on technology, expertise and operational support working together.
 
SecureXpert complements Microsoft Sentinel by helping organisations strengthen the operational effectiveness of their security capabilities. While Microsoft Sentinel provides the visibility, intelligence and automation needed to identify threats, SecureXpert supports organisations as they continue to develop and mature their security operations.
