Automate phishing simulations and reduce third-party security costs through AI integration
I consider integrating AI into our system to be one of the most valuable features of Microsoft Security Exposure Management because, as I mentioned, humans get tired and cannot work 24/7. AI can store more knowledge than a human brain. Therefore, using and integrating AI into our system is going to help us become more secure and improve our scores faster, in my opinion.My impression of Microsoft Security Exposure Management's ability to provide unified security insights across multi-cloud, SaaS, identity, OT, IoT, and non-Microsoft tools is quite positive. I was very impressed with the keynotes and the session about the new Security Copilot and cloud agents. I feel this will change the IT perspective significantly. People will start thinking about how to use AI and integrate it to make our environment more secure and work more efficiently, allowing us to focus on more innovative tasks. You do not have to sit down all the time; you can let the agent run automatically and follow a more secure path. I believe this is going to be a really great innovation. I evaluate the impact of Microsoft Security Exposure Management on our SOC operations efficiency from pre- to post-breach protection positively. We utilize a third-party security platform named Recon, which helps us monitor external attacks. However, we also have Microsoft Defender as a secondary secure layer. We receive notifications when users access untrusted websites or download large amounts of data from untrusted apps. As soon as we receive a notification, we contact our third party, Recon. With the changes I learned, I feel we no longer need a third-party tool. We can build an agent just like Recon did, and integrate it into our system to handle all the work, which means saving tons of money for the company, making everyone happy. The critical asset management feature of Microsoft Security Exposure Management helps in tagging and prioritizing high-value assets significantly. We also use a third-party organization for managing critical vulnerabilities and utilize the HPS dashboard. They provide us with monthly patches since Microsoft has a monthly update cycle. They show us pending updates or indicate if there are updates several months behind, highlighting critical vulnerabilities we must address. However, integrating Microsoft vulnerability management with the agent will be very beneficial. We can eliminate third-party tools and utilize the agent correctly, inputting the necessary knowledge that will save us a lot of money.

Centralized security testing has improved vulnerability remediation and compliance reporting
I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"With the new agent deal, we are set to eliminate all third-party tools once we are ready, which will save us at least $100,000 per year."
"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."
"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."
 

Cons

"I find the pricing, setup costs, and licensing for Microsoft Security Exposure Management a bit confusing because they do not clearly communicate what licenses are needed to access all features."
"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."
