Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

Email protection has stopped phishing and secured cloud collaboration across all devices
Deployment is very easy since it is API based and does not require any harsh configuration. The DMARC management and DMARC forensic is the best feature. Their security engine provides everything such as DLP and encryption. Check Point Harmony Email & Collaboration provides almost 100% security for phishing emails. Their DMARC management is very standard compared with any other brand or any other email security provider. The best thing is that on a single tenant I can manage multiple services such as Harmony Endpoint, Check Point Harmony Email & Collaboration, Harmony Browser, mobile security, EDR, XDR, which is endpoint security, and SaaS. All of these services have a single dashboard. When giving security to email, in Check Point Harmony Email & Collaboration, I do not need to change any MX record or any DNS entry changes. I simply add one text record for DMARC and no changes are needed in the MX record of that particular domain. This is very easy because Check Point Harmony Email & Collaboration is in the tenant of Microsoft Office 365 and Google Workspace only. Check Point works on zero trust network technology. They are not only giving a feature of artificial intelligence but also machine learning summary. Machine learning summary is also given when they catch any kind of incidents such as phishing attacks, malware attacks, and ransomware attacks. They always provide real-time alerts for that. Real-time URL analysis is provided for phishing links and all these things. It gives 100% output for that and shows the source from where the malicious URL comes from. Additionally, they always provide threat emulation. This means the simulation of what danger happens when I click that particular URL is also provided in their report. It gives 100% protection to all BYOD devices. For example, one single Microsoft 365 account can be configured on different five devices. Many companies give email access to their employees on their mobile as well. In that case, if any malicious file is on the mobile and the employee would like to save it on OneDrive, due to this security, the user and administrator will get a real-time alert that this file is malicious and cannot be uploaded to OneDrive. This not only saves money but also saves time and prevents the organization from such cyber attacks.

Advanced rollback and AI-driven insights have protected endpoints and simplified security operations
We can check multiple types of alerts and triggers, and we can analyze these. There are many types of functions such as Kill, Quarantine, and remediate rollback types of features, which we can use for client safety. The rollback feature is the best feature because it is only used in SentinelOne Singularity Cloud Security. We have used multiple types of EDR, but the rollback feature is unique to SentinelOne Singularity Cloud Security. When many types of attacks happen in an organization, the rollback feature deletes all types of malicious files and other malware-type files and completely cleans your system. This feature is very interesting according to me. SentinelOne Singularity Cloud Security provides many types of features such as Kill and Quarantine, which are very interesting features for security operations. There are deep visibility features, and Purple AI is also one of the best features. It is easy for security operations and incident response. We can check log analysis with the help of deep visibility, and any types of attacks, malware, and phishing attacks are detected by SentinelOne Singularity Cloud Security. Many types of security operations can be tracked and observed with the help of SentinelOne Singularity Cloud Security. Purple AI is one of the interesting features in SentinelOne Singularity Cloud Security. Deep visibility is one of the best features in SentinelOne Singularity Cloud Security. You can find any types of logs and any types of devices through searching portals, similar to Google search. It gives you information regarding this. With deep visibility, you can search for any name. For example, we can search for any name and check what is happening with that person's laptops, what USB is connected or disconnected, and whether the network is connected or not. This is with the help of Purple AI.
