Case studies

Interana uses ESM while planning public cloud upgrades to 18.04

Due to the large amounts of customer data that Interana handles, ensuring that security was tight was a priority. Rather than rush the upgrade from Ubuntu 14.04LTS, which would have been a major inconvenience for its customers, Interana turned to Canonical and ESM.

TIM maintains system security and client confidence with ESM

To ensure the ongoing security of Ubuntu 14.04 LTS machines, ESM provided TIM, the world's largest trade recommendations network, the freedom to upgrade within their own timeframe.

This approach saved time and money for this finserv organisation.

ESM on public clouds
with Ubuntu Pro

If you are running Ubuntu 18.04 LTS images on the public cloud and are looking for continued security coverage with ESM, it is recommended to launch new, Ubuntu Pro images for Azure, AWS and Google Cloud. Ubuntu Pro images are paid, premium images that are optimised and priced for the cloud, with security and compliance features built-in.

Ubuntu 18.04 LTS out of standard security maintenance

Ubuntu 18.04 LTS Bionic Beaver, one of the most popular Ubuntu releases, has reached the end of standard support. If you continue to run Ubuntu 18.04 LTS without ESM, you will not receive any security updates after 31 May 2023. Watch a webinar to explore your options.
