IT Security Expert at Alior Bank S.A.
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.
SK
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.
Harish (Kumar) - PeerSpot reviewer
Cybersecurity And Information Governance Head at Aeren
Email security has blocked sophisticated phishing and now protects inboxes with AI detection
The only challenge with Check Point Email Security (formerly Harmony Email & Collaboration) is that it is an API-based solution. In an API-based solution, the major challenge is that it can read email content and Google Drive content. This presents a data privacy challenge, and we had to mitigate it by signing a Data Processing Agreement and other agreements. Because it is not a traditional in-line solution, Check Point Email Security (formerly Harmony Email & Collaboration) connects with Google Workspace using API permission and can access email, attachments, sender, recipient information, links, and all metadata is with Check Point. Data storage and everything else is with Check Point, which is the challenge. This solution has a drawback because of API deployment, while other solutions are traditional secure email gateways that are in-line solutions. In those solutions, we need to change the MX record, but with this solution we do not need to change the MX record, which is a pro of API-based deployment. However, there is also a con in that with API solutions, the email is scanned but after delivery in the mailbox.
