Recently, they have been under serious attack with major exploits, such as Log4j, affecting Fortinet and Palo Alto, and even Cisco and VMware.
AI-based recommendations save on time and money.
If a customer is already using Microsoft’s ecosystem, the ROI can be positive due to seamless integration.
We attribute our growth to Sentinel.
From a risk perspective, it's about mitigating risk, and as mentioned earlier, we haven't missed many things since we've had the offering in market—only a couple of minor incidents.

Sentiment score
8.0
Microsoft Sentinel offers scalable, adaptable security solutions using Azure, ideal for various organizations with its flexible and updated features.

Office 365 and Exchange are running on it, covering about 35,000 users efficiently.
As our organization uses Microsoft Azure and Defender, everything grows together, and we can integrate various features seamlessly.
Being a SaaS solution, the scalability of Microsoft Sentinel is robust.
 

Stability Issues

Sentiment score
7.1
Azure Web Application Firewall is stable and reliable, with rare performance issues, mainly solved by system restart.
Sentiment score
7.8
Microsoft Sentinel is highly reliable, with 99.9%+ availability and occasional minor issues, maintaining stability across diverse environments.
Very rarely do I see any latency issues.
So far, we have not experienced any issues, and it has been stable from the beginning.
In the past two years, our team hasn't encountered any issues with the stability of Microsoft Sentinel from an operations perspective.
I need to be aware of deprecated connectors as they may disconnect, but the data continues to be sent with a need for quick adaptation.
 

Room For Improvement

Azure WAF needs improvements in management, deployment simplicity, affordability, IP support, and comprehensive documentation for better user experience.
Microsoft Sentinel users seek better integration, user-friendliness, documentation, AI capabilities, and customizable features with improved performance and pricing.
Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead.
We have some tools, such as our off-site Meraki firewalls, that have not fully integrated with Sentinel.
Currently, we are happy to have a way in the middle with not so much cost, but it would be nice to have the ability to enhance the automation of workflows based on learned incidents.
There are complexities in calculating the right pricing tier for different customers, which makes it difficult for me as a consultant during upfront pricing.
 

Setup Cost

Enterprise users find Azure Web Application Firewall cost-effective and straightforward compared to AWS and GCP, especially in Brazil.
Microsoft Sentinel's usage-based pricing offers strong value with extensive integration, but cost unpredictability concerns some users.
It is even a lower cost compared to AWS and GCP.
Sometimes, when opting for a higher SKU, it's not the WAF itself that's costly but the additional requirements.
Microsoft Sentinel offers more capabilities than Bastion, with a more intuitive experience.
Setting up the right cost model for customers is intricate, requiring careful consideration of various components and licensing tiers.
The ingestion costs for the data analytics is usually the highest cost.
 

Valuable Features

Azure Web Application Firewall offers scalable, easy-to-configure protection with flexible pricing, enhancing security against DDoS and unauthorized access.
Microsoft Sentinel provides AI-driven automation, robust threat detection, scalability, and seamless integration for comprehensive security operations within the Microsoft ecosystem.
With Microsoft, everything is within a single suite, making it easier to configure and plan.
It is almost impossible to access these assets from outside, requiring a very skilled attacker to obtain asset tokens of a customer using Azure.
Microsoft Sentinel's ability to correlate data from multiple sources and its detection capabilities are essential.
Microsoft Sentinel has improved cost efficiency, which is one of the key areas we're able to win business against the ability to have threat intelligence.
Microsoft Sentinel's ability to correlate data from multiple sources enhances our threat detection capabilities beyond what is a simple data lake solution by filtering out the noise and consolidating the signal down to a meaningful level that is easier to investigate and see.

Featured Reviews

Mano Senaratne - PeerSpot reviewer
Comprehensive suite simplifies configuration while frequent updates require management
Mainly, it comes with the complete suite of Microsoft services. I can use it in conjunction with the best options and other features that come with it. Configuration is much easier than using different platforms. For example, if I have hosted the application in AWS and am using the Application Firewall from Azure, there are certain additional steps to follow when configuring them. With Microsoft, everything is within a single suite, making it easier to configure and plan. Azure continually upgrades platforms and sends us messages to upgrade to the next version, simplifying the process. Later, it's much easier if I want to upgrade the software platform, scale it, or move it to a different application host as the whole suite comes together. The return on investment is good. If I am doing applications for clients, I can invoice them for better costs. Most applications that I run and use have a better return on investment.
