We are excited to be sharing Zentables-addons with the open source community so everyone can benefit from the performance gains we were able to achieve.

ZENEDGE, a leading provider of cloud-based, Artificial Intelligence (AI) driven cybersecurity solutions, announced today that the Company is contributing a Linux kernel extension called Zentables-­addons to open source​, developed to increase the capacity to block IP addresses behind an HTTP load balancer, such as HA Proxy or ​Amazon ELB​.

Many organizations have virtualized environments deployed in the cloud. Cloud platforms such as Rackspace, Azure and AWS offer HTTP(S) load balancers, such as HAProxy​ and Amazon ELB. By running behind a Load Balancer that is not under the organization’s control, the organization loses the ability to use traditional software firewalls such as iptables. A work-around exists by moving the IP blocking to Layer 7, the application layer, but comes at the expense of performance. Zentables-addons offloads the IP blocking from userspace to the kernel, alleviating the performance issue.

In ZENEDGE lab tests, the Zentables-addons achieved great results by offloading blocking of IPs from the userspace to the kernel, increasing blocking capacity by ​66% from pre­identified malicious IPs based on Proxy​ Protocol inspection. On a virtual test environment, ZENEDGE observed an improvement of 15,000​ RPS to ​25,000 RPS by moving the blocking logic from Layer 7 (Nginx or Apache) to Zentables-­addons.

“ZENEDGE is a strong believer and supporter Open Source software,” said Leon Kuperman, CTO at ZENEGE. “We are excited to be sharing Zentables-addons with the open source community so everyone can benefit from the performance gains we were able to achieve.”
