Log ingestion and retention costs can grow quickly, and understanding which data source is driving cost is not always straightforward.
Cyber Security Consultant at HR Software Solution
We have some tools, such as our off-site Meraki firewalls, that have not fully integrated with Sentinel.
Systems Emgineer at a non-profit with 1-10 employees
There are complexities in calculating the right pricing tier for different customers, which makes it difficult for me as a consultant during upfront pricing.
senior cyber security at a tech services company with 201-500 employees
The adoption rate will be less compared to other products, as this can be a time-taken process because all my data needs to be offloaded and the system needs to understand my existing alerts, logs, and other things.

Featured Reviews

Kallamuddin Ansari - PeerSpot reviewer
Cyber Security Consultant at HR Software Solution
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.

Consolidated security operations have improved detection speed and reduced SOC costs
There is room for improvement when it comes to the technical support quality and expertise of SentinelOne. Sometimes, the technical support team does not know how to resolve certain issues and takes time to respond, often requiring follow-up interactions within 24 hours. SentinelOne Singularity AI SIEM can be improved in terms of support capabilities. Some logs from the server side need to be ingested. Secureworks was integrating with domain controllers and other systems, but SentinelOne still has some gaps. Some vendors cannot be integrated directly. For example, we are using Cisco Umbrella for DNS security, and we have to integrate it through an Amazon S3 bucket where we dump the logs and SentinelOne reads them from that location. For some Microsoft integrations, we must enable certain storage components and pay Microsoft directly to retrieve logs. There is no direct integration, so we must access the logs through that workaround. Previously with Secureworks, we had direct integration with Microsoft. Direct integration with Microsoft is not available now. SentinelOne needs to work on many product integrations to enable direct connectivity.
