System Administrator at Templars
Opportunities for improvement overshadow benefits
Microsoft support is great overall. However, their business model of outsourcing to third-party partners, especially in Nigeria with tech experts and other partners, needs improvement. I have raised tickets and worked with these support teams. Microsoft needs to address how partners treat their technical support staff. The quality of support is affected because most support staff seem focused on obtaining five-star ratings rather than resolving problems thoroughly. This appears to be due to the pressure from partners and Microsoft's feedback metrics system. They often rush to close tickets without deeply investigating complaints. From the level of support received, I usually try to resolve issues independently. I rate the engineers favorably understanding their pressures, even when issues remain unresolved. Overall, I would rate Microsoft Support five out of 10.

Centralized monitoring has improved threat response but cost control still needs refinement
Based on real operations used in our corporate IT environment, the key features include log correlation and incident view. Microsoft Sentinel's biggest strength is how it correlates multiple related alerts into a single incident. This significantly reduces alert noise and helps the SOC focus on real threats instead of isolated events. Another valuable feature is KQL-based threat hunting with Kusto Query Language. The flexibility of this language allows us to build custom hunting queries based on our environment's behavior. This is extremely useful for detecting low and slow threats or hidden threats that default rules may miss. Cloud-native scalability and stability is another important feature. Being cloud-native, Microsoft Sentinel scales well for medium to large corporate environments without infrastructure management. Stability has been solid in day-to-day production. SOAR automation using playbooks is a feature we highly recommend. Microsoft Sentinel's SOAR functionality helps automate repetitive SOC tasks like alert enrichment and notification. This saves analyst time and improves response consistency.
