Cloud DevOps Engineer at a consultancy with 10,001+ employees
CIS hardening has simplified secure container workloads but AppArmor still blocks Docker by default
The CIS L1 AppArmor enforcement breaks Docker out of the box. Containers fail to start with a permission denied on the containerd task directory. There is no documentation about this. A simple note explaining that Docker users need to either update the runc AppArmor profile or disable it would save a lot of debugging time. It takes a while to trace the failure back to AppArmor blocking runc writes to /run/containerd/.

Centralized networking has secured multi-cloud data pipelines and improves analytics reliability
VNS3 could improve in terms of ease of setup, as while it is powerful, initial configuration for complex multi-cloud topologies can still feel quite technical and requires strong networking knowledge. Another potential improvement would be to tighten native integration with modern data stack tools; Airflow, dbt, and cloud data warehouses can benefit from more out-of-the-box connectivity templates. Additionally, the user interface and observability experience could be more modern and intuitive, especially for quickly diagnosing network flows without diving deep into logs. A pain point regarding needed improvements is that troubleshooting can still feel quite network engineering heavy. For data teams in my organization, we often want more pipeline-level visibility, such as directly seeing which ETL jobs or data flows are impacted when a tunnel or route changes. I would also appreciate more automation around policy setup, such as having auto-generated secure network templates for common data architectures such as AWS to Snowflake or on-premises to BigQuery, which would significantly reduce setup time.

Quotes from Members

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

Pros

"The hourly software charge is small relative to the engineering time we used to spend building and maintaining our own hardened AMI."
"The same-day engineering support has been very valuable."
"ClearScale Ubuntu 26.04 LTS is an excellent choice for organizations adopting cloud-native technologies and modern DevOps practices."
"Once you get that launch template dialed in, the image is incredibly solid."
"The pre-applied CIS L1 benchmark is the main selling point, as getting a hardened baseline without manual effort is genuinely useful and the Ubuntu 26.04 LTS base also means I'm on a supported, up-to-date kernel with long-term security patches."
"VNS3 has positively impacted my organization by centralizing management and reducing operations overhead in terms of manpower and cost."
"People should try VNS3 as we have not faced any issues with this product and I recommend it to others."
 

Cons

"Because the firewall ships default-deny, the first launch in a new environment takes a little planning to open the exact ports the app and load balancer health checks need."
"The CIS L1 AppArmor enforcement breaks Docker out of the box."
"Enterprise management and compliance tooling could be more comprehensive out of the box."
"It'd be cool to have more detailed changelogs with each new release so we can see exactly what packages got updated without having to boot up a test instance and diff it ourselves."
"VNS3 could improve in terms of ease of setup, as while it is powerful, initial configuration for complex multi-cloud topologies can still feel quite technical and requires strong networking knowledge."
"VNS3 could benefit from additional features such as the ability to share files through a pre-signed URL, which would be useful for team members to collaborate."
