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.

Senior IT Auditor at Ernst & Young
Has provided automated threat detection and daily malicious activity insights while supporting seamless orchestration with existing dashboards
I would assess the integration of AWS GuardDuty with Threat Intelligence as majorly positive; no threat intelligence is 100% accurate, and there are a few false positives, but as a security engineer, this must be accepted, and overall, the response and service is good for us. We do not directly use AWS GuardDuty dashboard by itself, as we have our own integrated security dashboard; AWS GuardDuty gives the feed to that dashboard, and it's giving us a satisfactory view of how the security landscape looks. We use metrics such as zero-day threats, any malicious traffic, and any traffic which originates from OFAC countries to measure its effectiveness, as we are majorly into a financial institution, as any traffic that is from a malicious IP or a rogue device. I don't see any significant negative points regarding AWS GuardDuty; it's a good product to have if you're a cloud consumer. I rate AWS GuardDuty nine out of ten overall.

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.
