Featured Reviews

Olakunle Obasoro - PeerSpot reviewer
DevOps Engineer at Exponential Craft
Security posture has become visible and container risks are managed proactively
Regarding improvements for Calico Cloud, there is a need to build agentic security systems. I believe Calico Cloud is progressing towards this, and I believe they can enhance their teaching methods to facilitate adoption. Documentation needs continuous improvement. It is good and easy to read, but it can get better. Having a searchable summary feature, such as a chatbot, could help users quickly resolve issues without having to read extensive documentation. At the moment, I do not believe there are more improvements needed, but as mentioned earlier, there should be a focus on better documentation, possibly by embedding chatbot features that could respond to user prompts effectively.

Comprehensive monitoring boosts security, yet incident management features need expansion
Fortinet FortiSIEM should broaden its remediation part to include more features for incident management. Currently, to manage repetitive incidents or for remediation, I need to use a separate software called FortiSOAR. Additionally, the search functionality in FortiAI should be improved to provide more precise results, making it easier for me to understand what actions need to be taken.
